Parts of a Plant
Name: ________________________
Read the definitions then label the diagram:
flower - Flowers produce the seeds of a plant.
leaf - Leaves convert energy from sunlight into food for
the plant through a chemical process called
photosynthesis.
root - Roots take food and water from the soil, store energy,
and provides support for the plant. Most roots grow
underground.
stem - The stem is the main support of the plant.
Labeling Parts of a Flower:
Important Information
The Flower:
The flower is the reproductive unit of some plants (angiosperms). Parts of the flower include petals, sepals, one or
more carpels (the female reproductive organs), and stamens (the male reproductive organs).
The Female Reproductive Organs:
The pistil is the collective term for the carpel(s). Each carpel includes an ovary (where the ovules are produced;
ovules are the female reproductive cells, the eggs), a style (a tube on top of the ovary), and a stigma (which
receives the pollen during fertilization).
The Male Reproductive Organs:
Stamens are the male reproductive parts of flowers. A stamen consists of an anther (which produces pollen) and
a filament. The pollen consists of the male reproductive cells; they fertilize ovules.
Fertilization:
Pollen must fertilize an ovule to produce a viable seed. This process is called pollination, and is often aided by animals
like bees, which fly from flower to flower collecting sweet nectar. As they visit flowers, they spread pollen around,
depositing it on some stigmas. After a male's pollen grains have landed on the stigma during fertilization, pollen tubes
develop within the style, burrowing down to the ovary, where the sperm fertilizes an ovum (an egg cell), in the ovule.
After fertilization, the ovule develops into a seed in the ovary.
Types of Flowers:
Some flowers (called perfect flowers) have both male and female reproductive organs; some flowers (called imperfect
flowers) have only male reproductive organs or only female reproductive organs. Some plants have both male and
female flowers, while other have males on one plant and females on another

Plant Adaptations Mini-Project
Learning Target: I am able to give examples and explain how characteristic animal behaviors of animals and specialized
plant structures increase their odds of reproduction.
Knowledge Probe:
Plants have specialized in a number of different ways to encourage survival in different environments and successful
reproduction. Flowering plants have different adaptations to enable their seeds to be dispersed as far away as possible.

Where does your plant grow? (Which biome)
What is one adaptation it has for gaining food, water, and nutrients?
o Label it as structural or behavioral.
Explain adaptations for reproduction and pollination
o Include a description of the structural or behavioral adaptation and how it benefits the plant’s odds at
successful reproduction
