Question

define photosynthesis​

Answer 1

Answer:

It is the process by which green plants make their food.

Explanation:

In photosynthesis,plants make their food from simple inorganic substances like(co2, water, sunlight) using chlorophyll to absorb heat from sun.It take place in all green plants ,blue green algaeand cyanobacteria.

Answer 2

$\huge\mathbb\red{ANSWER}$

Definition:

In plants, leaves prepare their food by utilizing water and carbon dioxide in the presence of sunlight by a process called photosynthesis.

What is necessary for photosynthesis:

➙Photosynthesis is the making of food by plants. The essential ingredients in making this food are sunlight, the chlorophyll that is present in green plants, water and carbon dioxide in the air.

➙Photosynthesis is necessary not just for plants to make food for themselves, but for animals, including us eventually.

The quantum yield of photosynthesis:

The number of photons or quanta required by a plant or leaf to release one molecule of oxygen during photosynthesis is called quantum requirement. It has been observed that in most of the cases the quantum requirement is 8.

Quantum yield:

The number of oxygen molecule evolved by one quantum of light in photosynthesis is called as Quantum yield. Hence the quantum yield is 0.125 or 12.5%.
