What are prokaryotes?

Back

Prokaryotes are single-celled organisms that lack a nucleus and membrane-bound organelles. They are generally smaller than eukaryotic cells.

Front

What organelle is responsible for making ATP?

Back

The mitochondria are the organelles that produce ATP, the energy currency of the cell.

Front

Define multicellular organisms.

Back

Multicellular organisms are living beings that consist of many cells, which work together to perform various functions.

Front

How do particles move in diffusion?

Back

Particles move from a region of high concentration to a region of low concentration until equilibrium is reached.

Front

What is the difference between active and passive transport?

Back

Active transport requires energy (ATP) to move substances against their concentration gradient, while passive transport does not require energy and moves substances along their concentration gradient.

Front

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.

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 role of chloroplasts?

Back

Chloroplasts are organelles found in plant cells that conduct photosynthesis, converting light energy into chemical energy.

Front

What is the function of ribosomes?

Back

Ribosomes are the cellular structures responsible for protein synthesis, translating messenger RNA into polypeptide chains.

Front

What is the cell membrane?

Back

The cell membrane is a biological membrane that separates and protects the interior of all cells from the outside environment.
