plant tissue term 3

Question 1

what are 2 plant tissue forms

Answer 1

meristimatic tissue
permanent tissue

Question 2

define meristematic tissue

Answer 2

-plant tissue that undergoes change and can divide.
-they change into permanent cells eventually

Question 3

define permanent tissue

Answer 3

-plant tissue that does not divide and grow further
-they develop for specific functions

Question 4

what are ground tissues

Answer 4

tissues made of identical cells
-parenchyma
-collenchyma
-chlorenchyma
-sclerenchyma

Question 5

Function of meristematic tissue

Answer 5

For plant growth
Initially undifferentiated
Make new cells

Question 6

Function of sclerenchyma

Answer 6

lignin thickening strong
Provides structure
support of various regions of the plant

Question 7

Function of parenchyma

Answer 7

Store food and water
Allow gas diffusion
Allow water movement
Packing tissue (some degree of support)

Question 8

Function of Chlorenchyma

Answer 8

makes up mesophyll in leaf
photosynthesis (chloroplasts)
Spongy mesophyll allows movement of gases

Question 9

Function of collenchyma

Answer 9

flexible support

Question 10

what are the vascular tissues

Answer 10

vascular makes you think of vein-like tubes xylem
phloem

Question 11

list of the function of the xylem

Answer 11

transports water
strenghthen and supports

Question 12

list the three groups permanent tissues are divided into

Answer 12

dermal tissue
vascular tissue
ground tissue

Question 13

what is the function of epidermal tissue

Answer 13

covers the plant
its cuticle protects the plant and prevents water loss

Question 14

what is the function of vascular tissue

Answer 14

transports water and nutrients

Question 15

what is the function of ground tissue

Answer 15

fills the space between the epidermal and vascular tissues, also performs other function

Question 16

whats a non permeable substance that strengthens permanent tissue

Answer 16

lignin

Question 17

what is the structure of the xylem tissue

Answer 17

it contains:
vessel elements
tracheids
sclerenchyma fibres

Question 18

what is the structure of phloem tissue

Answer 18

it contains:
sieve tubes (has no nuclei, kept alive by companion cells)
companion cells
parenchyma cells

Question 19

what is the function of the phloem tissue

Answer 19

transports food produced through photosynthesis
takes it from the leaves to the rest of the plant

Question 20

Function of epidermal guard cells

Answer 20

Open or close pores (stoma)
control entry and exit of gases

Question 21

Function of epidermal root hairs

Answer 21

Increased surface area of root
Increased water and mineral uptake

Question 22

Function of phloem sieve tubes

Answer 22

Transport manufacture organic food
From source to sink e.g. leaves to other tissues

Question 23

Function of phloem companion cells

Answer 23

Keep sieve tube cells alive
Regulate sieve tube functioning

Question 24

Functions of xylem tracheids

Answer 24

Lateral water and mineral transport
Strength and support

Question 25

Functions of xylem vessels

Answer 25

Transport water and disolved minerals
‘big pipes’
Unidirectional movement from roots up stem to leaves

Question 26

what tissues are the supportive tissues

Answer 26

collenchyma sclerenchyma xylem pholem and parenchyma

Question 27

what are the transportation tissues

Answer 27

xylem phloem and parenchyma

Question 28

function of the pericycle

Answer 28

strengthen and protect vascular bundle

Question 29

function of the endodermis

Answer 29

controls water entering the vascular bundle

Question 30

what is the cortex

Answer 30

allows water to move towards vascular bundle
