Plant Tissues

Question 1

Main Tissues in Plant

Answer 1

meristematic and permanent tissues

Question 2

Tissues that are responsible for plant growth. The cells present in these tissues constantly divide to produce new cells. This leads to an increase in the height and girth of plants.
- found in the growing areas of plants

Answer 2

meristematic tissues

Question 3

tissues in a plant that contain nondividing cells. The cells are also modified to perform specific functions in plants. The cells of this tissue are derived from the meristematic tissue. The cells are also fully differentiated. (matured merismatic tissue)

Answer 3

permanent tissue

Question 4

types of merismatic tissue

Answer 4

apical and lateral meristem

Question 5

meristematic tissues that are responsible
for the primary growth of plants.
- located at the tip of the root and shoot

Answer 5

apical meristem

Question 6

meristematic tissues that are responsible for the secondary growth of plants.
- increases the diameter of the plant
- located at the stems and roots at lateral side

Answer 6

lateral meristem

Question 7

two types of lateral meristem

Answer 7

vascular cambium and cork cambium

Question 8

lateral meristem that gives rise to secondary xylem and phloem. (Secondary xylem gives rise to wood.)

Answer 8

vascular cambium

Question 9

parts of wood

Answer 9

heartwood - dead cells, dense
sapwood - alive and functional xylem (lighter)

Question 10

what does the circles of wood of a tree determine

Answer 10

the age of tree, climate, season

Question 11

lateral meristem that gives rise to cork cells which replaces the epidermis of plants once they mature. This, along with cork and phloem make up the bark.

Answer 11

cork cambium

Question 12

Permanent tissue that is composed of only one kind of cell

Answer 12

Simple permanent Tissue

Question 13

Permanent tissue that is composed of two or more kinds of cells

Answer 13

Complex permanent Tissue

Question 14

Two types of simple permanent tissue

Answer 14

epidermal and ground tissue

Question 15

It covers the whole body of nonwoody and young woody plants and is protected by a waxy cuticle.

Answer 15

Epidermis

Question 16

Simple permanent tissue - epidermal

What does the cuticle do in the epidermis?

Answer 16

prevents loss of water
and invasion of disease-causing
microorganisms.

Question 17

Simple permanent tissue - epidermal

The epidermis in roots has _________ which help in increasing the absorption capacity of roots.

Answer 17

root hairs

Question 18

Simple permanent tissue - epidermal

In leaves and in stems, the epidermis has _________. These hair-like outgrowths prevent water loss and reflect excess light.

Answer 18

trichomes

Question 19

Simple permanent tissue - epidermal

The _______ and _____ parts of leaves are protected by the epidermis.

Answer 19

lower and upper

Question 20

Simple permanent tissue - epidermal

The lower epidermis of a leaf has
___________. They are specialized structures that regulate the opening and closing of stomata.

Answer 20

guard cells

Question 21

are slit-like structures on the lower epidermis of leaves that aids in the exchange of gases between plants and the environment.

Answer 21

stomata

Question 22

These cell types primarily support storage, and mechanical support, but can also serve for food production in the photosynthetic cells, or serve in wound healing and regeneration, depending on which class of cells they belong to.

Answer 22

ground tissue/fundamental tissue

Question 22

cells in ground tissue that are mostly responsible for
the synthesis and storage of plant food. Thin-walled and alive at maturity.

Answer 22

parenchyma

Question 22

cells in ground tissue that provides furnishing
flexible support to immature parts of plants. Thick-walled and alive at maturity

Answer 22

collenchyma

Question 23

cells in ground tissue that are thick-walled and dead at maturity. Provide support to the plant’s body.

Answer 23

sclerenchyma

Question 24

The only complex permanent tissue in plants

Answer 24

Vascular Tissues

Question 25

Two types of vascular tissue

Answer 25

Xylem and Phloem

Question 26

the specialised tissue of vascular plants that transports water and nutrients from the plant–soil interface to stems and leaves, and provides mechanical support and storage. (upward)

Answer 26

xylem

Question 27

cell types of xylem

Answer 27

tracheids, vessel elements, xylem parenchyma cells, fibers

Question 28

xylem cells that are thin and
elongated where water passes
through.

Answer 28

tracheids

Question 29

xylem cells that have perforated plates that allow the transport of
water through the vessels.

Answer 29

vessel elements

Question 30

the vascular tissue in charge of transport and distribution of the organic nutrients and food. (upward and downward)

Answer 30

phloem

Question 31

cell types of phloem

Answer 31

companion cells, sieve tube elements, phloem parenchyma cells, fibers

Question 32

Phloem is composed of
_____________ that help in the transport of nutrients throughout the plant’s body.

Answer 32

sieve tube elements

Question 33

Plant tissue is divided on the basis of?

Answer 33

function, shape, and size

Question 34

Defending tissues of the plant

Answer 34

Cork and Epidermis

Question 35

found between the upper and lower epidermis; it aids in gas exchange and photosynthesis via chloroplasts.

Answer 35

mesophyll
