Flashcards in Chapter 2.6a The need for transport in plants Deck (13):
1

Plants require water for transporting materials such as

minerals, for photosynthesis

2

Plants take up water by osmosis and minerals from the soil through the

root epidermis

3

The surface area of the root epidermis is increased by

root hair cells

4

Water and minerals taken up by roots are passed into tubes made up of dead

xylem cells

5

the cell walls of xylem cells contain a tough woody substance called

lignin

6

Water and minerals ass through the

plant stems to the leaves through xylem vessels

7

Water enters leaves in xylem vessels and passes into

spongy mesophyll cells by osmosis

8

Water evaporates into spaces in the

spongy mesophyll

9

Water vapour diffuses out of leaves through pores in the leaf epidermis called

stomata

10

The stomata open and close by movements of

guard cells found on either side of each pore

11

Loss of water though the leaves of a plant is called

transpiration

12

Sugars made by photosynthesis are transported around plants in

phloem tubes which are made from living cells

13

Phloem and xylem make up the

vascular tissue of flowering plants
