What is a cell membrane?

Back

A cell membrane is a biological membrane that separates and protects the interior of all cells from the outside environment. It is found in all types of cells, including plant, animal, and prokaryotic cells.

Front

What are the stages of mitosis?

Back

Mitosis consists of several stages: Prophase, Metaphase, Anaphase, and Telophase. Each stage plays a crucial role in cell division.

Front

What is the function of ATP in cells?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells. It releases energy when converted to ADP (adenosine diphosphate) during cellular processes.

Front

What structures are found in prokaryotic cells?

Back

Prokaryotic cells typically have a cell wall, cell membrane, ribosomes, and genetic material (DNA) but lack membrane-bound organelles like a nucleus.

Front

What is sexual reproduction?

Back

Sexual reproduction is a biological process that involves the combination of genetic material from two parents, resulting in offspring with variation in traits.

Front

What is a plant cell?

Back

A plant cell is a type of eukaryotic cell that has a cell wall, chloroplasts for photosynthesis, and a large central vacuole.

Front

What is an animal cell?

Back

An animal cell is a type of eukaryotic cell that lacks a cell wall and chloroplasts but has a flexible cell membrane and various organelles.

Front

What is binary fission?

Back

Binary fission is a form of asexual reproduction in which a single organism divides into two identical daughter cells.

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 Golgi apparatus?

Back

The Golgi apparatus is an organelle that modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.
