Transport in Plants

Question 1

What is transport in plants

Answer 1

Transport in plants refers to the movement of water, nutrients, hormones, and other essential substances throughout the plant body.

Question 2

What are the two main types of transport in plants

Answer 2

The two main types of transport in plants are:

Water and mineral transport (through the xylem).
Organic nutrient transport (through the phloem)

Question 3

What is the function of the xylem in plants

Answer 3

The xylem transports water and minerals absorbed from the soil upward from the roots to the leaves and other parts of the plant.

Question 4

What are the main components of the xylem

Answer 4

The main components of the xylem are:

Tracheids: elongated cells with tapered ends.
Vessel elements: wider, shorter cells with perforations in their walls

Question 5

What is transpiration

Answer 5

Transpiration is the process by which water is lost from the plant’s leaves through tiny openings called stomata

Question 6

How does transpiration contribute to water movement in plants

Answer 6

Transpiration creates a negative pressure in the leaves, causing water to be pulled upward through the xylem from the roots to replace the water lost.

Question 7

What factors affect the rate of transpiration

Answer 7

Factors affecting transpiration rate include temperature, humidity, wind speed, and light intensity.

Question 8

What is the function of the phloem in plants

Answer 8

The phloem transports organic nutrients such as sugars, amino acids, and hormones produced in the leaves to other parts of the plant for growth, storage, and energy.

Question 9

What are the main components of the phloem

Answer 9

The main components of the phloem are sieve tube elements and companion cells

Question 10

What are stomata, and what is their role in plant transport

Answer 10

Stomata are small pores found on the surfaces of leaves that regulate gas exchange and water loss through transpiration
