Explain if a plant was in a very dry environment, how diffusion and osmosis be affected?

1 answer:

3 0

Some plants have genetic modifications to tackle dry conditions and some plants in desert kind of atmosphere have specially adopted structures for effecting osmosis and diffusion.

Explanation:

Osmosis help plants to absorb water from soil. Diffusion is the process by which carbon dioxide diffuses to the leaves and then to the cells.
The genetic modifications in some of the plants can help in survive and adopt the osmosis in a very dry environment. They also develop defense methods to handle the water loss.
Some plants in a permanent dry environment like desert have special structures like reduced leaves, hairs, sunken stomata, and so on to conserve water.

Answer:

D) In case 1, both PS I and PS II completely lose function; in case 2, a proton gradient is still produced.

Explanation:

The light dependent reaction of photosynthesis, which produces the ATP and NADPH needed in the light independent stage of the process, includes complexes of proteins and pigments called PHOTOSYSTEMS. These photosystems (I and II) are key to the functionality of the light dependent reactions in the thylakoid.

The major pigment present in both photosystems is CHLOROPHYLL A, which absorbs light energy and transfers electrons to the reaction center. Chlorophyll B is only an accessory pigment meaning it can be done without. Hence, if all of the chlorophyll A is inactivated in the algae but leaves chlorophyll B intact as in case 1, both PS I and PS II will lose their function because Chlorophyll A is the major pigment that absorbs light energy in both photosystems.

In case 2, if PS I is inhibited and PS II is unaffected, a PROTON GRADIENT WILL STILL BE PRODUCED because the splitting of water into protons (H+) and electrons (e-) occurs in PSII. Hence, H+ ions can still be pumped into the inner membrane of the thylakoid in order to build a proton gradient even without the occurrence of PS I.
