Learn which plants thrive in your Hardiness Zone with our new interactive map! Like any living thing, plants go through a life cycle. Although each genus may have its own lifespan and duration of each development stage specific to its own species, all plants follow a standard pattern. The basic life cycle begins at the seed stage and ends with the regeneration stage; from there the life cycle starts all over again.
The seed embryo consists of cotyledons, which turn into the first leaves of a seedling. Monocotyledon monocot is the term used for species with one cotyledon, while dicotyledon dicot is for plants with two. There is no significant growth during this stage.
In order for a seed to germinate, the temperature must be right and there must be water to soak the seed.
As the seed coat absorbs water, it swells until it opens up. As water absorption increases, it stretches the radicle out into the taproot turning the cotyledons into leaves. As soon as the leaves start to open, the seedling stage begins. The root emerges first, penetrates the soil rapidly and anchors itself firmly in the soil. Growth stops on the side exposed to light and continues underneath until the seedling is in an upright position.
This happens as the hypocotyl the portion of the embryonic plant axis below the cotyledon arch emerges from the soil, where the cotyledons rise above the soil surface and expand. This exposes the growing point epicotyl of the seedling. The first true leaf emerges from a bud at the first stem node above the cotyledons. The plant uses the energy absorbed, water and carbon dioxide to produce oxygen and simple sugars, which it uses to make more complex sugars and carbohydrates to store energy.
It makes cell walls out of cellulose and hemicelluloses and with nitrogen to make proteins. The plant will use its energy depending on the stage of its development and environmental conditions.
When the plant receives five or more hours of light per day, the vegetative growth stage begins. In this stage, the plant rushes to grow leaves and stems that will support the growth of future flowers or fruits.
The vegetative stage varies from plant to plant. Vegetative growth continues through cell division mitosis and expansion in the epicotyl or growing point of the young plant. Some plants produce flowers when they turn into adults. Flowers contain male and female parts. In most plants, these appear together in the same flowers while in other plants they are separate flowers on the same plant.
Ovaries or carpels make up the female parts of the flower while male parts consist of stamens. During the flowering period, plants put all their energy towards reproduction. Different plants may differ in the manner they reproduce.
Some seeds will only develop once pollinated by a male plant. In other cases, the female plant will continue to produce more flowers in an effort to reproduce until fertilization happens sexual. In other plants, seeds will develop during the flowering stage without the need for pollination or fertilization asexual.

Regeneration is the method by which plants reproduce themselves. Seeds produced by plants will go through similar life cycles that parent plants went through.
Similarly, the nutritional needs of people and plants change as they grow. This graphic shows how a plant develops in this case, a tomato and highlights the changing nutrient needs for plants as they grow.
Each seed contains a small parcel of nutrients that is all they need to germinate and begin growing their first pair of leaves. As plants' roots develop and spread, a boost of quickly absorbed, well-balanced nutrients fuels the rapid growth from spindly seedling to healthy plant. Phosphorus is in extra high demand at the start of a plant's' reproductive cycle, the transition from growing leaves to forming buds.
17 Creative Ways to Teach Plant Life Cycle
Potassium plays a primary role in producing and transporting the sugars and starches plants use up as they develop healthy flowers and fruit. When flowers and fruit are verging on full maturity, they need a week or two of just water without nutrients, a process known as "flushing," so they can use up all of the nutrients they have already absorbed.

With multiple learning experiences, students can gain new ideas, demonstrate thinking, draw conclusions, develop critical thinking skills, and interact with peers through discussions and hands-on activities. With each stage in this lesson model, I select strategies that will serve students best for the concepts and content being delivered to them.
Students participate in distinguishing structures that define classes of animals and plants, and develop an understanding that all organisms go through predictable life cycles.
They learn that organisms depend upon one another for growth and development, discover that plants use the sun' energy to produce food for themselves, and that it gets transferred within a food chain from producers to consumers to decomposers.
They then explore these structures by dissecting a seed and locating them. After the seed dissection, I introduce other key terms germination and sprout by defining them and explaining that as the embryo in the seed begins to grow, the seed germinates and sprouts into a mature plant. Then, students apply what they have learned by creating a diagram that illustrates the life cycle of a plant, beginning with the seed.
They write brief descriptions about each part of the process. This assignment is started in class and continued at home for homework. I collect it the next day as a formative assessment.
Make observations of plants and animals to compare the diversity of life in different habitats. Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment.
Students take part in inquiry based investigations and apply their evidence to explain justify their thinking. Providing my students the opportunity to practice this type of learning will help to facilitate their scientific thinking for future investigations in any lesson.
Students are engaged in the following scientific and engineering practices. They use their experience in the investigation to create diagram a that illustrates and describes the life cycle of the plant.
Crosscutting Concepts. These Crosscutting Concepts include:. Responsibility, Accountability, and Independence. Depending upon the time of year, this lesson is taught, teachers should consider modeling how groups should work together; establish group norms for activities, class discussions, and partner talks.The plant life cycle starts when a seed falls on the ground.
There are many different kinds of plant life, but the flowering plants, or angiosperms, are the most advanced and widespread due to their amazing ability to attract pollinators and spread seeds.
Flowers are more than beautiful objects to look at or decorate with; they serve a very important purpose in the reproduction of plants. The major stages of the flower life cycle are the seed, germination, growth, reproduction, pollination, and seed spreading stages. The plant life cycle starts with a seed; every seed holds a miniature plant called the embryo.
There are two types of flowering plant seeds: dicots and monocots. An example of a dicot is a bean seed. It has two parts called cotyledons in addition to the embryo.
The cotyledons store food for the plant. Cotyledons are also the first leaves that a plant has-they emerge from the ground during germination. Monocots have only one cotyledon-the corn seed is an example.
Both kinds of seeds have the beginnings of a root system as well. The hard outside of the seed is called the seed coat and it protects the embryo. Some seeds are capable of growing even after many years if they are kept cool and dry. When a seed falls on the ground, it needs warmth and water in order to germinate; some seeds also need light.
Dicots have seed coats that soften with moisture. After being planted in the soil for a few days, the seed absorbs water and swells until the seed coat splits. Monocots have harder seed coats that do not split, but stay in one piece. The stem, called the hypocotyl, pushes through the soil along with the cotyledons, or seed leaves; this is called germination, or sprouting.Class 5 Science - Plant Germination - Learn about Seed Germination - Pearson
The tiny root pushes down and grows, looking for water and nutrients. Soon the cotyledons fall off and the first true leaves emerge. It is important that the seed is planted in the right place at the right time in order for it to germinate.
Some seeds need to go through a fire in order to sprout, such as prairie grasses. Some need to go through the stomachs of animals, or be scraped. Different seeds have different needs!
In order to complete the flower life cycle stage of growth, plants have to produce their own food. This process is called photosynthesis. As soon as the leaves emerge, they start the process of photosynthesis. Plants contain chloroplasts in the leaves which convert the energy from sunlight, carbon dioxide, and water into sugars, which they use as food.
The plants store the sugars in the roots and stem. The root system continues to develop, anchoring the plant into the ground and growing root hairs which help the plant to better absorb water and nutrients. The stem grows longer towards the sun and transports water and food between the roots and leaves.
Stages of Plant Life Cycles
Sugars and starches are changed into energy used to make new plant growth.Plants have a life cycle, just like humans and other animals. The plant life cycle describes the stages the plant goes through from the beginning of its life until the end when the process starts all over again. The life cycle of a plant begins with a seed.
Some non-flowering plants, such as ferns, begin with spores. You are probably familiar with seeds and may have even eaten a few, such as sunflower or pumpkins seeds. A seed has a protective coating called the shell. The shell contains everything needed to start a new plant.
How Plants Grow
Inside the seed coating is an embryo, which will become the new plant, and the endosperm, which provides the nutrients for the embryo. Seeds are dispersed, or spread, in a variety of ways. Some are blown by the wind. Others float on water. Still, others are carried by birds, beesother insects, or on the fur of animals. Some are even eaten by animals and spread through their waste. And, of course, humans plant seeds for their fruit or to make their lawns attractive. Seeds need four things to grow: oxygen, moisture, sunlight, and the right temperature.
When the proper conditions are met for the seed, it will begin to sprout. The roots push their way through the seed coating and begin growing into the soil. This process is called germination. A small, fragile young plant called a seedling will then poke its way out of the ground and start growing towards the sunlight. The seedling gets many of the nutrients it needs to grow from the soil through its roots.
