What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water, and releasing oxygen as a byproduct.

Front

What factors can affect the rate of photosynthesis?

Back

Factors include light intensity, carbon dioxide concentration, temperature, and water availability.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily from the sun, which is essential for photosynthesis.

Front

What is the equation for photosynthesis?

Back

6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂ (Carbon dioxide + Water + Light energy → Glucose + Oxygen)

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell.

Front

What are the phases of mitosis?

Back

The phases of mitosis are prophase, metaphase, anaphase, and telophase.

Front

What happens during metaphase?

Back

During metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres of the chromosomes.

Front

What is gel electrophoresis?

Back

Gel electrophoresis is a laboratory technique used to separate DNA fragments based on their size and charge.

Front

Why do DNA fragments move in gel electrophoresis?

Back

DNA fragments move towards the positive electrode because DNA is negatively charged.

Front

What is DNA fingerprinting?

Back

DNA fingerprinting is a technique used to identify individuals based on unique patterns in their DNA.
