structure of a leaf

Question 1

waxy cuticle

Answer 1

Protects leaf from water loss and also protects leaf from pathogen entry.

Question 2

Upper epidermis

Answer 2

Protective layer of the cell that are mostly transparent to allow light through the leaf to reach the palisade cell

Question 3

Palisade Cell in the palisade mesophyll tissue

Answer 3

Main cell that photosynthesises. Contains a lot of chloroplasts.

Question 4

Chloroplast in the palisade cell

Answer 4

organelle responsible for photosynthesis which uses chlorophyll to capture light energy to convert carbon dioxide + water into glucose.

Question 5

Spongy Cell in the spongy mesophyll tissue

Answer 5

Allow gas exchange to occur so that CO2 can get into the leaf for photosynthesis and O2 out (other way around when the leaf does cellular respiration)

Question 6

Xylem in the vascular bundle

Answer 6

Carries water and mineral ions from the roots in the soil to the leaves

Question 7

Phloem in the vascular bundle

Answer 7

Carries the glucose made by the leaves of the plant to other parts in the form of sucrose

Question 8

Air spaces

Answer 8

Large air spaces are located between these cells allow gases to get in and out

Question 9

Lower epidermis

Answer 9

Similar to the upper epidermis, it provides a protective layer for the underlying plant tissues.

Question 10

Stomata

Answer 10

Tiny pores on the underside of a leaf that allow gases to flow in and out of the leaf and also allow transpiration to occur.

Question 11

Guard Cells

Answer 11

Open and close to control size of the stomata.
