What is the function of lysosomes in a cell?

Back

Lysosomes are known as the 'junk yard' of the cell; they break down waste materials and cellular debris.

Front

What happens if a cell lacks a cell membrane?

Back

The cell will not be able to monitor what goes in and out, leading to potential dysfunction.

Front

What is the primary role of the excretory system?

Back

The excretory system is responsible for the removal of liquid waste products from the body.

Front

What occurs to skin cells when they are damaged?

Back

Damaged skin cells divide and produce new skin cells to repair the injury.

Front

What are the two main sources of energy for plant cells?

Back

The two main sources of energy for plant cells are mitochondria and chloroplasts.

Front

Define the role of mitochondria in a cell.

Back

Mitochondria are known as the powerhouse of the cell; they generate ATP through cellular respiration.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are responsible for photosynthesis, converting light energy into chemical energy.

Front

Explain the importance of the cell membrane.

Back

The cell membrane regulates the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the significance of cell division in tissue repair?

Back

Cell division is crucial for tissue repair as it replaces damaged or dead cells, allowing for healing.
