transport system in plants

Question 1

what are the main organs in plants

Answer 1

roots, stems and leaves

Question 2

what are the roots responsible for (2)

Answer 2

absorbing water and minerals and holding the plant in place

Question 3

what does the stem do in a plant

Answer 3

provides support for the leaves and buds

Question 4

what do the leaves do in the plant

Answer 4

they are the site of photosynthesis

Question 5

what is photosynthesis

Answer 5

the process in which plants makes there own food using sunlight

Question 6

what is the primary role of a leaf

Answer 6

to carry out photosynthesis

Question 7

name the tissues in plant leaf that contain chloroplast

Answer 7

spongy mesophyll, palisade mesophyll

Question 8

which structure are responsible for opening and closing the stomata

Answer 8

guard cell

Question 9

which structure in the leaf helps reduce evaporation from the leaf surface

Answer 9

waxy cuticle

Question 10

name the structure which allows movement of gases into and out of the leaf

Answer 10

stomata

Question 11

which structure allows plants to carry out the process of photosynthesis

Answer 11

palisade mesophyll

Question 12

what is the function of the waxy cuticle in the leaf

Answer 12

helps prevent evaporation of water

Question 13

what is the function of the upper epidermis tissue in the leaf

Answer 13

be the protective outer layer

Question 14

what is the function of the palisade mesophyll tissue in the leaf

Answer 14

contains many chloroplast. Most photosynthesis occurs here

Question 15

what is the function of the spongy mesophyll tissue in the leaf

Answer 15

some photosynthesis occurs here. The large, moist, air spaces are important for diffusion of gases within the leaf

Question 16

what is the function of the xylem vessel in the leaf

Answer 16

transports water and minerals

Question 17

what is the function of the phleom vessel in the leaf

Answer 17

transports glucose around the plant

Question 18

what is the function of the lower epidermis tissue in the leaf

Answer 18

protective outer layer

Question 19

what is the function of the guard cells tissue in the leaf

Answer 19

control opening of stomata and therefor control gas exchange

Question 20

what is the function of the stomata in the leaf

Answer 20

allows gas exchange to occur

Question 21

what does the xylem transport

Answer 21

water

Question 22

what does the phloem transport

Answer 22

glucose

Question 23

what direction does the xylem transport

Answer 23

up

Question 24

what direction does the phloem transport

Answer 24

all directions (up and down)

Question 25

are the phloem cells dead or living

Answer 25

living

Question 26

are the xylem cells dead or living

Answer 26

dead

Question 27

what are the factors affecting transpiration (4)

Answer 27

wind speed, humidity, light/dark and surface area

Question 28

what does the plants transport system enable them to carry

Answer 28

water and minerals

Question 29

what is most of the water in a plant lost to

Answer 29

evaporation

Question 30

what is the process of evaporation in a plant known as

Answer 30

transpiration

Question 31

what cell do water and minerals enter the plant through

Answer 31

root hair cells

Question 32

what is the cell wall of the xylem strengthened by

Answer 32

Question 33

what do plants carry out gas exchange through

Answer 33

stoma

Question 34

what is the apparatus that measures transpiration called

Answer 34

a potometer

Question 35

what is transpiration

Answer 35

the process of water movement through plant

Question 36

what does water move form the soil into the root hair through

Answer 36

osmosi

Question 37

what are sieve tubes

Answer 37

parts of the phloem tube that glucose move through
