Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, typically along the concentration gradient.

Front

What is active transport?

Back

Active transport is the movement of substances across a cell membrane against the concentration gradient, requiring energy, often in the form of ATP.

Front

What is homeostasis?

Back

Homeostasis is the maintenance of a relatively stable internal environment within an organism, often involving feedback regulation.

Front

What is the role of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and support.

Front

What are the main differences between plant and animal cells?

Back

Plant cells have cell walls, chloroplasts, and a large central vacuole, while animal cells do not.

Front

What is DNA replication?

Back

DNA replication is the process by which a cell makes an identical copy of its DNA before cell division.

Front

What is the function of chloroplasts?

Back

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

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, generating ATP through cellular respiration.

Front

What is a concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance across a space, driving passive transport.

Front

What is feedback regulation?

Back

Feedback regulation is a process in which the output of a system regulates its own production, maintaining homeostasis.
