Why is sunlight necessary in photosynthesis?

Answer 1

you do not necessarily need sunlight but without light there is no photosynthesise because a plant needs it to preform photosynthesis.

Yes you do! The human body required sunshine in order to synthesize Vitamin D. Without adequate sunshine or compensating nutrition you will suffer from rickets, a deforming disease.

Answer 2

NO, It does not need sunlight. It just needs light. Sunlight is referred to most of the time because of its intensity and quality.

Answer 3

sunlight is necessary in photosynthesis because its date is the sun . the sun and the plants like to play love games with each other, which attracts the making of food because there bond is intelectualy firm and strong !

Answer 4

Llight is the most important factor that affects photosynthesis because it provides the energy necessary for driving the reaction. On a sunny day, the process is at its peak and on a cloudy day, when there is less light, the process slows down.

On the atomic level, a photon comes toward the chlorophyll pigment in the chloroplasts in the cells of the plant. The chlorophyll gets electrically excited and transfers the energy to the center of a group of pigments. Enough energy is realized at this center pigment which excites a valence electron in the Magnesium atom, moving the electron further from the center of the atom and into a conduction band. Once in the conduction band the electron moves to a different molecule. This movement of electrons allows chemical reactions to proceed, which eventually produce high energy molecules and oxygen gas.

Answer 5

Most animals inhale or metabolise oxygen and exhale carbon dioxide.

Photosynthesis is the process whereby plant take in Carbon Dioxide and convert it to Oxygen and sugars (for the plant to grow).

Thus photosynthesis converts Carbon Dioxide back into Oxygen so animals can continue breathing relatively good levels of Oxygen. secondly the glucose/ sugars which the plants produce during photosynthesis (for growth) are eaten by animals, which in turn are eaten by other animals and people - providing food.

Answer 6

That is what the plant "feeds" on to make the process of photosynthesis

Answer 7

The sunlight gives nutrients to the plant.
