The light reactions stage:
(a) occurs before the calvin cycle
(b) requires light energy to work
(c) releases oxygen through the stomata
(d) all of the above

(D) all of the above

Explanation:

The light reactions stage, occurs before the Calvin cycle, requires light energy to work, and releases oxygen through the stomata.

The light reactions stage occurs before the Calvin cycle , requires light energy to work  and releases oxygen through the stomata.

D) all the above

Explanation

The light reactions stage is one of the two stages which occur during the chemical reaction of photosynthesis.

It is the first stage and second stage is Calvin cycle. So the first option is true which states that the light reactions stage occurs before the Calvin cycle.

In light reactions stage, the light energy of sun is captured by the chloroplast and this energy is the main trigger for starting the light reaction stage between the reactants carbon-di-oxide and water.

So the second option is also true i.e., the light reactions require light energy to work.

In light reaction stage, the water molecules will release oxygen gas from the stomata.

Thus all the options are true for light reactions stage in photosynthesis.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
