stomata located on top of leaf

2018-02-12 04:38:13 UTC

- so leaf can be in contact with air
- allows gas to be exchanged

Adaptations : Hydrophytes

2018-02-12 04:38:38 UTC

- No waxy cuticle or they can be very thin, this is because they do not need to conserve water.
- Their stomata remains open all the time and the stomata is located on the upper surface of the leaf. Hydrophytes have no problem with getting enough water for photosynthesis and transpiration.
- Hydrophytes have large air spaces in their leaves, to help keep their leaves near the surface of water where there is more light available for photosynthesis.

- water loss is not a problem so there are no protective layer
- surface cell is to absorb nutrient and dissolved gas
- adapted to live in wet conditions
- the leaves are often dissected for large surface area for absorption and photosynthesis
- the chloroplast is located in the upper surface

Adaptation

2018-02-12 04:40:20 UTC

- Leaves are divided for large surface for absorption and photosynthesis.
- No waxy cuticle
- Stomata on top
- Lack xylem
- Thick waxy layer on top to repel water
- Smaller roots and usually there are no root hairs.

Adaptations
- Submerged leaves are divided creating a large surface area for absorption and photosynthesis.
- Emergent leaves are much less divided and have similar structures to those of land plants.
- No waxy cuticle as they live in water so no water needs to be conserved.
- Chlorophyll and stomata only on upper surface where most of the sunlight will reach.

Hydrophytes

Leaf shape- submerged leaves- increase surface area for absorption and photosynthesis- floating- similar internal structure.
Lack of protective layer- no or little cuticle- lack of stomata underside the leaf. Water loss is not a problem.
Stomata located on the upper surface of the leaves, has a thick waxy cuticle to repel water and to keep stomata clear and open. chloroplasts on the upper surface

small roots

2018-02-12 04:42:53 UTC

- water can diffuse directly into the leaf and stem
- less need for roots to absorb water

Plant adapted to live in extremely wet conditions. Common adaptations to increase the rate of gaseous exchange: Leaf Shape: The submerged leaves are often highly dissected or divided to create a very large surface area for absorption and photosynthesis.

2018-02-12 04:46:31 UTC

-Stomata and chloroplast only found in the upper surface.
-All surface able to absorb water,dissolved gasses and nutrients directly from water.
-Adapted to live in extremely wet condition
-Air sacs allow them to float more sunlight exposure for photosynthesis

air sacs

allows leaves and flowers to float on water
