7.2 Vascular System: Xylem And Phloem

Question 1

Describe how the sugar and mineral ions are transported across the plant

Answer 1

The substances transported such as mineral ions and organic compounds dissolve in water to form solutions and these solutions are moved through specialised.

Question 2

What is the vascular system?

Answer 2

System of fluid filled tubes, vessels or spaces most commonly used for long distance transport in living organisms.

Question 3

What are two examples of vascular systems?

Answer 3

The blood vascular system in animals and the vascular system of xylem and phloem in plants
The lymphatic system which carries the fluid lymph

Question 4

The vascular refers to

Answer 4

Tubes or vessels

Question 5

What are the vascular tissues in plants in it’s vascular system?

Answer 5

Xylem and phloem

Question 6

What is xylem?

Answer 6

A tissue containing tubes called vessels and other types of cell responsible for the transport of water and mineral salts to a plant and for support.

Question 7

What is phloem?

Answer 7

A tissue containing cubes called sieve tubes and other types of cells responsible for the transport through the plant of organic solutes(assimilates) such as sucrose

Question 8

Both xylem and phloem contain ________ for transporting fluids

Answer 8

Specialised tubes

Question 9

The fluid transported in xylem or phloem is called

Answer 9

Sap(xylem sap or phloem sap)

Question 10

Xylem saps moves in tubes called

Answer 10

Xylem vessels

Question 11

Phloem sap moves in tubes called

Answer 11

Sieve tubes

Question 12

Xylem and phloem are together known as

Answer 12

Vascular tissue

Question 13

What is a vascular tissue?

Answer 13

A tissue in plans consisting mainly of xylem and phloem but also containing sclerenchyma and parenchyma cells

Question 14

What do xylem vessels mainly carry?

Answer 14

Water and inorganic ions(mineral salts) from roots to the parts above the ground

Question 15

Xylem sap can move in only one direction

Answer 15

From roots to the parts above the ground

Question 16

What does phloem sap carry?

Answer 16

Carries substances made by photosynthesis from the leaves to the other areas of the plants. it can also carry substances from the storage organs to other parts of the plant. These might be underground.

Question 17

At any one time, the fluid in the phloem can be moving

Answer 17

In different directions, in different tubes of the phloem, up or down the plant

Question 18

What is the difference between the vascular system of plants and mammals?

Answer 18

The fluids(blood) moves more rapidly in mammals than xylem or phloem
There is no obvious pump such as the heart in plant’s vascular system
