- gas exchange / transport



Slide 7 - Tekstslide

Slide 8 - Tekstslide

Slide 9 - Tekstslide

Structures of a leaf

Slide 10 - Tekstslide

What does the leaf do?
  • The palisade layer does photosynthesis.
  • The stomata do gas exchange.
  • The spongy layer stores gasses.
  • The veins transport chemicals into and out of the leaf.
  • The cuticle and epidermis protect the leaf.

Slide 11 - Tekstslide

Structures of a stem
xylem flows up. 

phloem flows down. 

Slide 12 - Tekstslide

What does the stem do?
  • The xylem transports water and chemicals up the plant.
  • The phloem transports water and chemicals down the plant.
  • The stem itself supports the weight of the leaves, flowers & fruits.

Slide 13 - Tekstslide

Structures of a root

Slide 14 - Tekstslide

What do the roots do?
  • The root cap senses where there is water.
  • The primary and lateral roots anchor the plant in the round and provide support.
  • The root hairs absorb the water and nutrients from the soil.

Slide 15 - Tekstslide

The plant absorbs sunlight through the palisade cells.
The plant absorbs water and nutrients through the roothair cells.
The plant transports water and nutrients up through the xylem vessels.
The plant transports sugars and nutrients down through the phloem vessels.
The plant absorbs carbon dioxide through the stomata cells.
The plant releases oxygen through the stomata cells.
