Transport in plants

Question 1

Transpiration

Answer 1

The loss of water, via evaporation, from the aerial parts of a plant mainly through the stomata in the leaves

Question 2

Cohesion

Answer 2

the attraction between water molecules due to H-bonds

Question 3

Adhesion

Answer 3

The attraction of water molecules to hydrophyllic substances

Question 4

Xerophytes

Answer 4

plants adapted to living in dry conditions

Question 5

hydrophytes

Answer 5

plants specifically adpated to living in water not soil

Question 6

Apoplast

Answer 6

the cell walls and itercellular-spaces of plant cells

Question 7

Apoplast route

Answer 7

movement of substances through the cell walls and cell spaces by diffusion and into the cytoplasm by active transport

Question 8

symplast

Answer 8

the continuous cytoplasm of living plant cells connected through the plasmodesmata

Question 9

symplast route

Answer 9

phloem loading through the cytoplasm via the plasmodesmata by diffusion (passive)

Question 10

sieve plates

Answer 10

Areas between the cells of the phloem where the walls become
perforated giving many gaps and a sieve-like appearance that allows the phloem contents to flow through

Question 11

Sieve tube elements

Answer 11

The main cells of the phloem that have a greatly reduced living
content and sieve plates between the cells

Question 12

Companion cells

Answer 12

The active cells found next to sieve tube elements that supply the phloem vessels with all of their metabolic needs
