Plant Basics
These green parts of the plant are where photosynthesis and gas exchange happen.
What are leaves?
These are plants that grow flowers and hide their seeds inside fruit.
What are Angiosperms?
These are often brightly colored to attract bees and butterflies to the flower.
What are petals?
Apples and cherries are called "fleshy" fruits, but a walnut is called this type of fruit.
What is a dry fruit?
A plant will grow toward this to make sure it can get enough energy for food.
What is light?
This part of the plant grows upward and supports the leaves and flowers.
What is the stem?
This soft, green plant doesn't have "real" roots or seeds and usually grows in damp places.
What is Moss?
This is the yellow powder made by the male part of the flower.
What is pollen?
To avoid competing for sunlight, plants use wind, water, or animals to do this to their seeds.
What is dispersal?
The "Venus Flytrap" is famous for closing its leaves when it feels this.
What is touch?
These are found underground; they drink up water and keep the plant from blowing away.
What are roots?
Instead of flowers, pine trees and fir trees use these to hold their seeds.
What are cones?
When a bee carries pollen from one flower to another, it is called this.
What is pollination?
This part of the plant develops from the ovary and protects the seeds inside.
What is the fruit?
This is a plant’s growth response toward or away from a stimulus.
What is a tropism?
Most plants start their life as one of these, which contains a tiny baby plant (embryo).
What is a seed?
These plants have big leaves called "fronds" and reproduce using spores instead of seeds.
What are ferns?
This is the female part of the flower that eventually turns into a fruit.
What is the carpel (or ovary)?
Dandelion seeds use this "natural force" to travel far away from their parent plant.
What is the wind?
If you put a plant in a dark box with a small hole, it will grow toward the hole because of this "phototropic" response.
What is positive phototropism?
Plants are different from animals because they use this green pigment to make their own food.
What is chlorophyll?
This group of plants, like the cactus, has a "vascular system" to move water, but no flowers or seeds.
What are Pteridophytes?
These tiny green leaf-like structures protect the flower while it is still a bud.
What are sepals?
This is the specific stage when a seed finally gets enough water and warmth to start growing.
What is germination?
This gas is like a "ripening signal" that tells a green banana it's time to turn yellow.
What is ethylene?
