Q2 CFA Review

Front

What process allows water to move into flower cells, making them healthy again?

Back

Osmosis: the movement of water from an area of low solute concentration to an area of high solute concentration through a semi-permeable membrane.

Front

What type of cells are rich in mitochondria and why?

Back

Muscle cells: they require a lot of energy for contraction and movement, which is produced by mitochondria.

Front

What are the main products of photosynthesis?

Back

Glucose and oxygen: plants convert carbon dioxide and water into glucose and oxygen using sunlight.

Front

What is the function of chloroplasts in plant cells?

Back

Chloroplasts convert solar energy into chemical energy through photosynthesis.

Front

Which organ is responsible for gas exchange in the respiratory system?

Back

Lungs: they allow oxygen to enter the blood and carbon dioxide to be expelled.

Front

Define diffusion in biological terms.

Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is the role of mitochondria in cells?

Back

Mitochondria are known as the powerhouse of the cell; they break down glucose to produce ATP, the energy currency of the cell.

Front

Explain the process of photosynthesis in simple terms.

Back

Photosynthesis is the process by which green plants use sunlight to make their own food (glucose) from carbon dioxide and water.

Front

What is the primary function of vacuoles in plant cells?

Back

Vacuoles store nutrients, waste products, and help maintain turgor pressure in plant cells.

Front

What is the significance of the nucleus in a cell?

Back

The nucleus stores genetic information (DNA) and controls the cell's activities.
