plant tissues

Question 1

xylem

Answer 1

(dead) made of lignified cells, found in vascular bundle and transports water and nutrients around the plant

Question 2

phloem

Answer 2

(living) made of cells , found in vascular bundle and transports food away from the leaves

Question 3

epidermis

Answer 3

upper - 1 cell thick, found under cuticle and provides protection and transparent allowing for sunlight to enter chloroplasts
lower - 1 cell thick, found at the bottom of the plant, and contains guard cells (and stomata) for controlled transpiration

Question 4

mesophyll

Answer 4

palisade - found under epidermis, packed vertically to fit more space and contains chloroplasts for photosynthesis
spongy - very loosely packed, allowing for gaseous exchanges and transpiration to occur (does contain very few chloroplasts)

Question 5

cuticle

Answer 5

waxy, transparent layer found at the top of the leave. it is meant for retaining water, and protecting the leaf as well as allowing for photosynthesis to occur

Question 6

stoma

Answer 6

gaps in the underside of the leaf allowing for transpiration surrounded by guard cells

Question 7

guard cells

Answer 7

large vacuole containing cells that allow for the stoma to open and close at day and night

Question 8

root hair

Answer 8

allows for osmosis to transport nutrients in water into the root, to travel up the xylem with adhesion and cohesion

Question 9

epidermis

Answer 9

trichomes - adapted epidermal cells on the leaf
