Structure and Function
The structure and function of plant parts is evidence of adaptation. Plant populations and species develop defenses against consumers, ways to attract pollinators, and seed dispersal to ensure survival.
Common Plant Parts There are more than half a million different types of plants, and even though they look different, they all have some common parts. Most plants have: Roots Stems Leaves Flowers
All plants must find and take in nutrients food carbon dioxide water
Roots Most roots act as anchors to keep the plant in the ground.
Roots take in water and minerals from the soil through tiny root hairs. Roots can also store food. Different roots are also adapted to their different environments.
Some roots spread out in search of water in places where it rains often such as in a rain forest.
Roots carry water and minerals to the plant.
Some roots grow deep into the ground in search of water in places where it rains very little such as a desert.
Special Roots These roots begin on a stem rather than below the ground. They are used for support to prop or brace up the tree.
Storage Roots Some plants are able to store food in their roots for later use. People grow these plants to eat such as sweet potatoes, carrots, beets, and radishes.
