Question

What are the conditions necessary for glucose production in a leaf

Answer 1

In simple all the conditions which are required for photosynthesis, is same as what conditions required to produce glucose in a leaf.

Which are :

1. Chlorophyll
2. Sunlight
3. Carbon-dioxide
4. Water

This follows as given below :

"$\textbf{ Photosynthesis " }$

It is the process by which green plant and some other organism use sunlight to synthesize nutrients from carbon dioxide and water.

The main product form here is glucose and by products are oxygen and water.

Here it takes place in chlorophyll and I'm presence of sunlight.

There are two stages of photosynthesis :

1. Light reactions :

It occurs in the grana where photon are absorbed so as to excite electrons of chlorophyll to a higher energy level. These activated elctrons are harnessed to form ATP from the ADP and reduce NADP to NADPH. Wayer ia also spotted here and oxygen is released.

2. Dark reactions :

Calvin cycle occurring in chlorophyll here carbon combine with 5-carbon sugar called ribulose biphospahte. This unstable compound breaks down into 3-carbon compound. This then forms glucose.

Answer 2

The conditions necessary for glucose production in a leaf are:

(i) Photosynthesis Reaction: Green plants make food by photosynthesis reaction. Hence, it must take place to produce glucose.

(ii) Presence of Light: Plants generally use sunlight to produce glucose. So it must be present (artificial light can also work).

(iii) Presence of Chlorophyll: Chlorophyll is the green pigment due to which photosynthesis happens. Hence it is also a must condition for glucose production.

(iv) Presence of Carbon dioxide: Carbon dioxide is the main reactant in photosynthesis. In its absence, glucose will not be produced.

(v) Presence of Water: Without water, plants cannot make glucose.
