Structure of a Leaf

Question 1

what is the function of a Spongy Layer in a leaf?

Answer 1

Air spaces between cells allow the movement of gases

Question 2

what is the function of Xylem in a leaf?

Answer 2

To transport water from the roots to the leaves

Question 3

what is the function of phloem in a leaf?

Answer 3

To transport the products of photosynthesis to the rest of the plant

Question 4

what is the function of a stomata in a leaf?

Answer 4

To Allow gases to move in and out of the leaf

Question 5

palisade mesophyll cells

Answer 5

Palisade mesophyll cells are tall and narrow, and have many chloroplasts. These are found near the leaf’s upper surface so that the chloroplasts can absorb light for photosynthesis.

Question 6

root hair cells

Answer 6

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

Question 7

phloem cells

Answer 7

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

Question 8

guard cells

Answer 8

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