Chapter 5 - Plant Tissue, Organs And Systems

Question 1

What flows up the Xylem tissue and what is the process called

Answer 1

Water flows up the xylem tissue from roots to leaves during transpiration

Question 2

What does Phloem cells carry and what it is called

Answer 2

Phloem cells carry the glucose made in photosynthesis from leave of a plant to the other parts of the plant during translocation.

Question 3

What is meristem?

Answer 3

Region of plant tissue in which stem cells are produced and plants growth occurs.

Found in shoot tips towards the sun and root tips following gravity

Question 4

Why are plant roots white?

Answer 4

Because they don’t contain any chloroplasts for photosynthesis.

Question 5

What do roots absorb?

Answer 5

Water by osmosis.

Minerals by active transport for the soil.

Question 6

What are the layers in a leaf?

Answer 6

Cuticle 
Epidermis 
Palisade mesophyll cells
Spongy mesophyll cells
Guard cell 
Stomata

Question 7

What is translocation?

Answer 7

The movement of dissolved food through the phloem.

Question 8

What are the functions of Transpiration?

Answer 8

Providing water for the leaves

Providing water to cells for the process of photosynthesis.

Transporting minerals to the leaves.

Question 9

When does high rate of transpiration happen?

Answer 9

There is more wind

High temperature

The air is less humid

The light intensity is high (during the day)

Question 10

Diffusion of substances in a plant

Answer 10

Diffusion of any substance happens faster if the concentration gradient is greater.
