Transport in Plants

Question 1

Give 8 features of the xylem:

Answer 1

-Made up of thick walled dead cells
-Which contain no cytoplasm
-Cells are hollow
-And arranged end to end
-Cell walls contain lignin - waterproof
-End walls have broken down to form a continuous transport system
-Transports water
-And mineral ions (both from roots to leaves)

Question 2

Give 6 features of the phloem:

Answer 2

-Consists of living cells
-Tubes are formed by cells arranged end to end
-Cell walls made of cellulose
-Transports sucrose
-And amino acids (both from leaves to growing/storing points)
-Moving sucrose and amino acids around the plant requires energy, this is called translocation

Question 3

What do plants take in water through?

Answer 3

Root hair cells

Question 4

How do mineral ions move into the roots?

Answer 4

Through active transport.

Question 5

Give 2 adaptations of root hair cells and how this helps movement:

Answer 5

-Thin walled (short diffusion distance)
-Hair-like extensions which increase surface area greatly

Question 6

How does water move into the roots?

Answer 6

Through osmosis
