Cell Biology Concepts and Processes

Front

What is the function of chloroplasts in plant cells?

Back

Chloroplasts are organelles that conduct photosynthesis, converting light energy into chemical energy in the form of glucose.

Front

What is the powerhouse of the cell?

Back

The mitochondria are known as the powerhouse of the cell because they produce energy (ATP) through cellular respiration.

Front

What does homeostasis refer to in biological systems?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite external changes.

Front

What is photosynthesis?

Back

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

Front

What is a hypertonic solution?

Back

A hypertonic solution is one that has a higher concentration of solutes compared to the inside of a cell, causing the cell to lose water and shrink.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is ATP and its role in the cell?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes are biological catalysts that speed up chemical reactions in the body without being consumed in the process.

Front

What is the difference between a hypotonic and hypertonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of a cell, causing the cell to swell, while a hypertonic solution has a higher concentration, causing the cell to shrink.

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.
