|
|
|
This is the green pigment of plants, where is it found
|
chlorophyll, in the chloroplasts
|
|
|
What are cotyledons
|
Cotyledens are sturctures in a seed that are designed for food absorptiona nd storage.
|
|
|
What is photosythesis
|
The food-manufacturing process of plants.

|
|
|
What does the root system do for a plant
|
The root system anchors the plant to the soil, absorbs water and minerals for growth and stores food.
|
|
|
What are root hairs
|
Tiny hairs that develop from the sides of the root and force their way between soil particles to absorb water and dissoved minerals.
