moisture from the ground and prevent the grazing animals from
pulling them out.
10. Trees with needle-like leaves retain less water than broad leave
Answers
6. Potato is a Tuber.
7. True An epiphyte is a plant that grows on other plants, but is not dependent upon the other plant for nutrition atmosphere
8. True Like any other plant, photosynthesis in cacti takes place in chloroplasts. ... Since the largest amount of chloroplasts are present in the leaves , they are the site of mainstream photosynthesis. But Cactus has no leaves . Its leaves are modified into spines, an adaptation to reduce transpiration
9. True .The temperate grass is called Prairie absorbs moisture and dies soon causing the soil fertile. Even during a fire the root portion sprouts again. The grazing animals cannot uproot them that easily as they are strongly rooted downwards.
10. True. broad leaves have greater surface area so, transpiration takes place effectively and easily. but trees having needle like leaves retain less water because very less transpiration takes place. hence they retain less water.
