Plants are extremely important to all forms of life on our planet. Plants use carbon dioxide from the air, water and sunlight to produce food and oxygen.


Plant Reproduction

Plants are living things, and all living things need to reproduce. Different plants have different life cycles. Some only live for a very short time during one growing season while others may live a few hundred years like Sequoiatrees in California. The reproductive cycle of a living thing is linked to its life cycle.

Sexual Reproduction in Flowering Plants

A flower may have both male (pollen) and female parts (eggs). The male and female parts join to form a seed which will house the embryo (baby plant). Bees and other pollinators may carry pollen from flower to flower. After the male and female cells join together (fertilization), an embryo (baby plant) starts to develop in a seed within the ovary. The ovary enlarges and turns into a fruit containing the seeds. Fruits vary in colour, size, shape, smell, and many other ways. Some fruits are edible. Many animals help with seed dispersal.

Ovule: The female part of the flower,
which after fertilization develops into a seed.

Seed Dispersal

After seeds are developed, they need to be dispersed to increase their chance of survival. Most plants use the following methods to disperse their seeds

Animal Carriers

Water Dispersal

Coconuts are dispersed by gravity and water

Wind Dispersal

Dandelion seeds are dispersed by wind.


When the time is right, seeds germinate.

Other Forms of Reproduction

Plants may use other methods to reproduce. These are vegetative or asexual reproduction when the plant produces a clone of itself without seeds. Plants can also use bulbs, tubers, etc. for food and water storage to help them survive during harsh conditions such as droughts and during seasonal periods when they are dormant.

Plant Growth Test (PDF file)

  • These are printable tests about plants. They are designed for grade 3 students, but it's useful for other grades as well. The tests have a variety of different questions such as (drawing, labelling, True and False, Point Form, Fill in the Blanks, Open Ended, etc.)
