diffusion
green pigment found in plants and algae that absorbs light and helps plants make food
chlorophyll
What does the word part "synthesis" mean?
to put together
specialized plant cells that control gas exchange and water loss in plants
Guard cells
What is the role of this pigment during the process of photosynthesis is to absorb light energy
chlorophyll
The movement of molecules from an area of low concentration to an area of high concentration is an example of

pores in the epidermis of leaves, stems, and other plant organs that control the exchange of gases between the plant and the atmosphere
stomata
This catalyst is necessary for photosynthesis to occur
light energy or solar energy
Why are plants also called "producers?"
they produce their own food
A root of a plant may continue to absorb minerals even though the concentration of these minerals is greater inside the cell than in the soil. This absorption is accomplished chiefly as a result of
