Front

What organelle is responsible for photosynthesis in plant cells?

Back

Chloroplast

Front

What is the relationship between Cell 'A' and Cell 'B' in terms of genetic information?

Back

Cell 'A' contains exactly the same genetic information as Cell 'B'.

Front

What happens when a cold front approaches?

Back

Warm air rises, cools, and causes rain and thunderstorms.

Front

What adaptation might a desert animal develop in response to high temperatures?

Back

They are active only at night.

Front

What is the primary function of capillaries in the circulatory system?

Back

Passing materials in blood cells.

Front

Define photosynthesis.

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the pigment that absorbs sunlight, allowing plants to convert light energy into chemical energy.

Front

Explain the significance of genetic information in cells.

Back

Genetic information determines the characteristics and functions of cells, ensuring that all cells in an organism have the same DNA.

Front

What are the characteristics of a cold front?

Back

A cold front is characterized by a boundary where a colder air mass replaces a warmer air mass, often leading to precipitation.

Front

List two adaptations of desert animals to survive in their environment.

Back

1. Nocturnal behavior (active at night). 2. Ability to conserve water.
