Biology - Plant tissues

Question 1

It is a group of cells that work together to perform a specific function

Answer 1

Tissues

Question 2

What are the two main types of plant tissues?

Answer 2

Meristematic (capable of cell division) and Permanent tissue (not capable of cell divsion)

Question 3

What is the function of meristematic tissue

Answer 3

For cell division and growth of the plant

Question 4

Where can meristematic tissue be found in a plant

Answer 4

Either the tips of roots/shoots (apical) or the vascular camium/length of roots and stems (lateral)

Question 5

What are the two types of permanent tissue?

Answer 5

Simple permanent tissue and complex permanent tissue.

Question 6

What is simple permanent tissue?

Answer 6

Simple permanent tissue consists of cells that are structurally similar and perform a single function. Examples include parenchyma, collenchyma, and sclerenchyma.

Question 6

What is the function of parenchyma tissue?

Answer 6

Parenchyma tissue is involved in photosynthesis, storage, and gas exchange. It is also the primary tissue found in leaves, stems, and roots.

Question 7

What is the function of collenchyma tissue?

Answer 7

Collenchyma tissue provides flexible support to growing parts of the plant, such as young stems and petioles.

Question 8

What is the function of sclerenchyma tissue?

Answer 8

Sclerenchyma tissue provides structural support and strength to the plant. It contains lignin and forms hard, woody structures.

Question 9

What is complex permanent tissue?

Answer 9

Complex permanent tissue consists of different types of cells that work together to perform a specific function. Examples include xylem and phloem.

Question 10

What is the function of xylem tissue?

Answer 10

Xylem is responsible for the transport of water and minerals from the roots to the rest of the plant.

Question 11

What is the function of phloem tissue?

Answer 11

Phloem is responsible for the transport of food (mainly sugars) produced by photosynthesis from the leaves to other parts of the plant.

Question 12

What is the difference between xylem and phloem?

Answer 12

Xylem transports water and minerals, while phloem transports food (sugars) throughout the plant.

Question 13

What are the main cell types found in xylem?

Answer 13

The main cell types in xylem are tracheids, vessel elements, xylem fibers, and xylem parenchyma.

Question 14

What are the main cell types found in phloem?

Answer 14

The main cell types in phloem are sieve tube elements, companion cells, phloem fibers, and phloem parenchyma.

Question 15

What is the function of epidermal tissue in plants?

Answer 15

Epidermal tissue acts as a protective barrier against water loss, pathogens, and physical damage. It also aids in gas exchange (through stomata).

Question 16

What is the role of the cambium in plant growth?

Answer 16

The cambium is a lateral meristem that allows the plant to grow in girth (thickness) by producing new xylem and phloem cells.

Question 17

What is the difference between primary and secondary growth in plants?

Answer 17

Primary growth increases the length of the plant, while secondary growth increases the thickness (girth) of the plant.

Question 18

What is the role of sclerenchyma in mature plants?

Answer 18

Sclerenchyma provides mechanical support and strength in mature parts of the plant, such as stems and seeds.

Question 19

How does the structure of xylem support its function?

Answer 19

Xylem cells have thick, lignified walls that help support the plant and allow for efficient water transport under high pressure.
