specialised cells- plant cells

Question 1

what does specialised cell mean

Answer 1

the organs are specifically adapted for their function

Question 2

what shape are palisade cells

Answer 2

cylindrical shaped

Question 3

why are palisade cells * shaped

Answer 3

so they pack tightly in the upper part of the leaf

Question 4

why do palisade cells contain many chloroplasts

Answer 4

to capture as much energy from the light as possible for photosynthesis

Question 5

why do palisade have a large vacuole

Answer 5

helps to keep the cell and leaf structure rigid

Question 6

palisade cell- why is it needed that the cytoskeleton can move chloroplasts around

Answer 6

to maintain photosynthesis in low light and to protect chloroplasts in intense light

Question 7

why are there long narrow gaps between palisade cells

Answer 7

to allow air to circulate for gas exchange

Question 8

why do palisade cells have a thin and transparent cellulose wall

Answer 8

for easy gas diffusion

Question 9

where are root hair cells found

Answer 9

in the epithelium

Question 10

root hair cell- the hair is a fine protrusion from the cell out into the cell what does this provide

Answer 10

a large surface area to volume ratio in order to absorb water and dissolved minerals from the cell

Question 11

root hair cell- why is the cell membrane thin and partially permeable to water

Answer 11

enables easier water absorption

Question 12

root hair cell- why are there channels in the cell membrane and carrier of proteins

Answer 12

to enable ions to cross the membrane into the cell, the short distance across the cell wall increases the rate of diffusion

Question 13

root hair cell- why is there many mitochondria

Answer 13

to help supply energy for active transport of minerals from the soil into the cell
