Which process( photosynthesis, cellular respiration, both) do algae preform when incubated in the light? in the dark?

Algae preforms both photosynthesis and cellular respiration when incubated in the presence of light.

Algae preform only the Calvin cycle part of photosynthesis and cellular respiration when incubated in the absence of light.

Photosynthesis involves the production of food by green plants in the presence of water, carbon dioxide and light energy.

Algae are green plants which performs both photosynthesis and cellular respiration The chlorophyll which is a  pigment found in the chloroplast traps light energy needed for photosynthesis.

We know that photosynthetic process involves the light  and dark phases.  The dark reaction is also called Calvin cycle. Under dark conditions, the algae only performs Calvin cycle and is unable to perform the light phase of photosynthesis.

All living organisms perform cellular respiration and isn't affected affected by any pigment or light exposure.

Explanation:

Algae do perform photosynthesis and cellular respiration during light just like other plant specie. They use chlorophyll a or b as pigments to collect light energy and drive the process of photosynthesis.

We know that photosysnthesis is basically a two step process i.e light reactions and dark reactions (dark reaction is also called Calvin cycle). So, in dark algae only performs Calvin cycle and shuts off the light harvesting steps of photosynthesis. However, cellular respiration keeps going throughout the life of algae without being affected. We can say that algae share these characteristics with the green plants.

Hope it helps! :)

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
