6.4 leaves: the green machine
Slide 1 - Slide
Photsynthesis:
- Plants use carbon dioxide, water and sunlight do to photosynthesis.
- Plants create sugars and oxygen.
- The sugars are used for growth and development ad the oxygen is released back into the atmosphere.
Slide 2 - Slide
Slide 3 - Slide
photosynthesis
water + carbon dioxide (+ sunlight) => glucose + oxygen
Slide 4 - Slide
Slide 5 - Video
LIMITING FACTORS:
- sunlight
- water
- carbon dioxide
- space
- other nutrients to help with growth
Slide 6 - Slide
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.
Slide 7 - Drag question
Slide 8 - Slide
waxy layer - upper outer layer - layer of cells performing photosynthesis - spongy layer - xylem/phloem (vein) - lower outer layer - stoma (pore with guard cells)

D
Xylem
Slide 11 - Quiz
What type of plant cell is specialised to help a plant breathe?
A
stomata
B
palissade cell
C

Slide 12 - Quiz
respiration and photosynthesis
photosynthesis
: turning sunlight into glucose (with carbon dioxide and water) => daytime
respiration
: burn glucose to release energy for the plant to use (cells to grow, cells to use for other processes) => daytime and night time!
