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)

Slide 10 - Drag question

Which vascular tissue transports water?
A
Phloem
B
Chlorophyll
C
Stomata
D
Xylem

Slide 11 - Quiz

What type of plant cell is specialised to help a plant breathe?
A
stomata
B
palissade cell
C
phloem
D
xylem

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!
