Answer 43

slide 48 and book

Question 44

whats a palisade mesophyll cell

Answer 44

Palisade mesophyll cells, tall and narrow, contain numerous chloroplasts located near the leaf's upper surface, which absorb light for photosynthesis.

Question 45

whats a root hair

Answer 45

Root hair cells have a long hair extending out, providing a large surface area to absorb water and nutrients. There are no chloroplasts, since these cells are underground.

Question 46

whats a phloem cells

Answer 46

Phloem cells are long and thin, with gaps at the end to allow sugary water to flow freely.

Question 47

whats a guard cell

Answer 47

Guard cells, on the underside of leaves, change shape to open the stoma (hole) to allow gases in and out of the leaf.

Question 48
