Question

look up and explain in your own words: why are (most) plants (usually) green?
water is absorbed by the roots. it must be moved into the leaves for photosynthesis.
glucose (sugar) is created in the leaves during photosynthesis. it must then be moved to other locations in the plant.

Explanation:

Most plants are green because they contain chlorophyll. Chlorophyll is a pigment that is essential for photosynthesis. It absorbs light energy (mainly in the blue and red wavelengths) and uses it to convert carbon dioxide and water into glucose and oxygen. The green color is due to the reflection of green light, as chlorophyll does not absorb green light as efficiently as other colors. This pigment is located in chloroplasts within plant cells, especially in the leaves where most photosynthesis occurs.

Answer:

Most plants are green because they have chlorophyll. Chlorophyll is crucial for photosynthesis. It soaks up light energy (mostly blue and red) and helps turn carbon dioxide and water into glucose and oxygen. The green hue comes from reflecting green light since chlorophyll doesn't absorb it as well as other colors. It's in chloroplasts, mainly in leaves where photosynthesis happens a lot.
