What are membrane-bound organelles?

Back

Membrane-bound organelles are specialized structures within a cell that are enclosed by membranes, such as the nucleus, mitochondria, and endoplasmic reticulum.

Front

What is the function of the nucleus?

Back

The nucleus is the control center of the cell, containing DNA and regulating gene expression and cell division.

Front

What is the cell wall?

Back

The cell wall is a rigid outer layer that provides support and protection to plant cells, fungi, and some bacteria.

Front

What is the function of chloroplasts?

Back

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

Front

What is a vacuole?

Back

A vacuole is a storage organelle in cells, larger in plant cells, used to store nutrients, waste products, and help maintain turgor pressure.

Front

Who is Robert Hooke?

Back

Robert Hooke was a scientist who first coined the term 'cells' after observing cork under a microscope.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, responsible for producing energy (ATP) through cellular respiration.

Front

What are organelles?

Back

Organelles are specialized structures within a cell that perform specific functions, such as the nucleus, mitochondria, and ribosomes.
