plant and animal tissues

Question 1

tissue

Answer 1

groups of cells that are the exact same, perform the
same function and occur in the same place in
large numbers

Question 2

types permanent tissues

Answer 2

epidermal, vascular and ground tissues

Question 3

epidermal tissues

Answer 3

cover the plant

Question 4

vascular tissues

Answer 4

transport water and nutrients

Question 5

ground tissues

Answer 5

fill the space between the epidermal and vascular tissues

Question 6

types of epidermal tissue

Answer 6

guard cells and root hairs

Question 7

structure of epidermal tissue

Answer 7

single layer tightly packed thin-walled cell

cover with waxy layer

Question 8

waxy layer covering epidermal tissue and function

Answer 8

cuticle protects plant and prevents too much water loss

Question 9

function of epidermal tissue

Answer 9

covers and protects plant
controls movement of water out of plant
roots absorb water

Question 10

types of ground tissues

Answer 10

parenchyma, collenchyma, chlorenchyma and sclerenchyma

Question 11

function of parenchyma

Answer 11

stores food and water

allows gases and water to move through plant

Question 12

structure of parenchyma

Answer 12

large vacuoles
loosely packed
large intercellular spaces
thin cellulose cell walls

Question 13

a tissue that that performs photosynthesis

Answer 13

chlorenchyma

Question 14

the function of chlorenchyma

Answer 14

stores starch
makes up mesophyll of leaf
allows gases and water to past between cells

Question 15

structure of chlorenchyma

Answer 15

parenchyma tissues with chloroplast
irregular shape in leaf mesophyll
large intercellular space in spongy parenchyma
small intercellular space in palisade parenchyma

Question 16

what provides mechanical support for plant

and provides strengthening tissue

Answer 16

collenchyma

Question 17

collenchyma structure

Answer 17

cell walls are unevenly thickened

thickness mainly occurs on the corners off cell walls

Question 18

types vascular tissues

Answer 18

xylem, phloem

Question 19

what is xylem

Answer 19

it contains non living material

Question 20

what is regarded a dead tissue

Answer 20

xylem

Question 21

what does xylem mainly consist of

Answer 21

xylem vessels and tracheids

Question 22

basic structure of xylem vessels

Answer 22

a series of elongated cells (connected end to end)
doesn’t contain cytoplasm
perforated cross walls
callouses walls are thickened by lignin
uneven thickening

Question 23

why do xylem vessels have uneven thickening

Answer 23

for additional strength and support
