A plant kept in the dark for several days shows poor growth. Explain why.

A plant kept in dark cannot perform photosynthesis properly, so it fails to produce enough food required for growth.

Key Factors

Factor	Impact	Explanation
Lack of Light	Stops photosynthesis	Light is essential to convert CO2 and water into glucose
Reduced Food Production	Energy shortage	Plant cannot make enough glucose
Chlorophyll Activity	Becomes inactive	Without light, chlorophyll cannot function properly
Growth Processes	Slows down	Cell division and elongation reduce

Stepwise Understanding

1. Plant is kept in dark, no light available

2. Photosynthesis process stops

3. No glucose (food) is produced

4. Plant starts using stored food

5. After some time, energy becomes insufficient

6. Growth becomes weak and slow

Important Concept

Photosynthesis is the primary source of food for plants, without it survival becomes difficult.

Real Insight

Plants kept in dark often become pale and weak, sometimes leaves turn yellowish because chlorophyll is not maintained properly.

So basically, without light, plant cannot produce its own food, which directly affects its growth.
