Explanation:
What role do these parts play?
Cell walls: provide structural and mechanical support, protect cells against pathogens, maintain and determine cell shape, control the rate and direction of growth and generally provide form to the plant.
Cytoplasm: provides the platform for most chemical processes, controlled by enzymes.
Cell membrane: acts as a barrier, controlling the movement of substances into and out of the cell.
Chloroplasts: As described above, simply contain chlorophyll, a green substance which absorbs light energy for photosynthesis.
Vacuole: the container that holds moisture, and keeps the plant turgid.
Nucleus: this contains genetic make (the DNA), which controls the activities of the cell.
Chlorophyll absorbs the light energy needed to make photosynthesis happen. It is important to note that not all the color wavelengths of light are absorbed. Plants mostly absorb red and blue wavelengths — they do not absorb light from the green range
