Flashcards in Plant Structure Deck (14):
1

axil

angle between leaf and stem

2

node

point at which the leaf is attached to the stem

3

internode

region on a stem between two nodes

4

bud

potential growth point which may develop into a shoot/ leaf/ flower

5

Herbaceous

contain no wood/ lignin

6

Woody

contain wood/ lignin

7

Lenticel

an opening on the stem for gas exchange.

8

Functions of roots

-Anchorage
-Absorbs water/ minerals
-stores food
-transports absorbed things to shoot.

9

Functions of stem

-supports aerial parts of plant
-sometimes stored food
-transports minerals from roots to leaves
-If green, photosynthesis also occurs here

10

Functions of leaves

-where photosynthesis takes place
-transpiration
-site for gas exchange
-stores food. eg. cabbage

11

Function of ground tissue

storage, support, photosynthesis, gives strength

12

Xylem

transports water and minerals throughout plant

13

Phloem

transports food throughout plant.

14

Lignin

strengthening material found in some plant cell walls
