Plant Tissues

Question 1

are made up of a group of similar cells that are adapted for a particular function. Organs are then formed by the functional grouping together of multiple tissues.

Answer 1

Tissues

Question 2

Plants are typically made up of roots, stems and leaves. Plant tissues can be broadly categorized into

Answer 2

dividing, meristematic tissue
or non-dividing, permanent tissue.

Question 3

Permanent tissue

Answer 3

is made up of simple and complex tissues.

Question 4

is made up of simple and complex tissues.

Answer 4

Permanent tissues

Question 5

is undifferentiated tissue.
Meristematic tissue contains actively dividing cells that result in formation of other tissue types (e.g. vascular, dermal or ground tissue).

Answer 5

Meristematic tissue

Question 6

is found in buds and growing tips of plants. It generally makes plants grow taller or longer.

Answer 6

Apical meristematic tissue

Question 7

is a type of primary meristematic tissue containing cells that can divide and promote the growth of the plant.
They are located at the base of internodes. The function of the intercalary meristem is to promote the lengthening of the stem and increase the height of the plant.

Answer 7

Intercalary meristematic tissue

Question 8

makes the plant grow thicker. Lateral meristems occur in woody trees and plants.

Answer 8

Lateral meristematic tissue

Question 9

makes the plant grow thicker. occur in woody trees and plants.

Answer 9

Lateral meristematic tissue

Question 10

is responsible for increasing the diameter of stems and roots and for forming woody tissue. The cork cambium produces some of the bark.

Answer 10

The vascular cambium

Question 11

is also found in root tips as this is where roots are growing and where dividing cells are produced

Answer 11

Meristematic tissue

Question 12

Once cells develop to perform this particular function, they lose their ability to divide. The process of developing a particular structure suited to a specific function is known as

Answer 12

cellular differentiation.

Question 13

1. Simple permanent tissues

Answer 13

• Epidermis
• Parenchyma
• Collenchyma
• Sclerenchyma

Question 14

2. Complex permanent tissues

Answer 14

• Xylem vessels (made up of tracheids and vessels)
• Phloem vessels (made up of sieve tubes and companion cells)

Question 15

(made up of tracheids and vessels)

Answer 15

Xylem vessels

Question 16

(made up of sieve tubes and companion cells)

Answer 16

Phloem vessels

Question 17

a single layer of cells that covers plants’ leaves, flowers, roots and stems. It is the outermost cell layer of the plant body and plays a protective role in the plant.

Answer 17

epidermis tissue

Question 18

a pore found in the leaf and stem epidermis that allows for gaseous exchange.

Answer 18

A stoma

Question 19

The stoma is
bordered on either side by a pair of specialized cells known as

Answer 19

guard cells

Question 20

Guard cells are bean shaped specialized epidermal cells, found mainly on the lower surface of leaves which are responsible for regulating the size of the stoma opening.
Together, the stoma and the guard cells are referred to as

Answer 20

stomata

Question 21

together these tissue types are referred to as ground tissues. Ground tissues are located in the region between epidermal and vascular tissue.

Answer 21

parenchyma, collenchyma and sclerenchyma cells,

Question 22

are located in the region between epidermal and vascular tissue.

Answer 22

Ground tissues

Question 23

forms the majority of stems and roots as well as soft fruit like tomatoes and grapes. It is the most common type of ground tissue.

Answer 23

Parenchyma tissue

Question 24

is responsible for the storage of nutrients.

Answer 24

Parenchyma tissue

Question 25

a simple, permanent tissue typically found in the shoots and leaves of plants.
Collenchyma cells are thin-walled but the corners of the cell wall are thickened with cellulose. This tissue gives strength, particularly in growing shoots and leaves due to the thickened corners. The cells are tightly packed and have fewer inter-cellular spaces.

Answer 25

Collenchyma tissue

Question 26

are thin-walled but the corners of the cell wall are thickened with cellulose. This tissue gives strength, particularly in growing shoots and leaves due to the thickened corners. The cells are tightly packed and have fewer inter-cellular spaces.

Answer 26

Collenchyma cells

Question 27

is a simple, permanent tissue. It is the supporting tissue in plants, making the plants hard and stiff. Two types of sclerenchyma cells exist: fibers and sclereids.

Answer 27

Sclerenchyma tissue

Question 28

Two types of sclerenchyma cells exist:

Answer 28

fibers and sclereids.

Question 29

are long, narrow and have thick lignified cell walls. They provide mechanical strength to the plant and allow for the conduction of water.

Answer 29

Sclerenchyma fibers

Question 30

are specialized sclerenchyma cells with thickened, highly lignified walls with pits running through the walls. They support the soft tissues of pears and guavas and are found in the shells of some nuts.

Answer 30

Sclereids

Question 31

COMPLEX PERMANENT
TISSUES

Answer 31

Xylem
phloem

Question 32

transports water and mineral salts from the roots up to other parts of the plant,

Answer 32

Xylem

Question 33

transports sucrose and amino acids between the leaves and other parts of the plant.

Answer 33

phloem
