Cell Theory & Organelles - 6th Period

Front

What is the Cell Theory?

Back

The Cell Theory states that: 1) All living organisms are composed of cells, 2) The cell is the basic unit of life, 3) All cells arise from pre-existing cells.

What is the function of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, providing protection and support.

Front

What are organelles?

Back

Organelles are specialized structures within a cell that perform distinct processes, such as energy production, protein synthesis, and waste processing.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and membrane-bound organelles.

Front

What is the role 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 function of the nucleus?

Back

The nucleus is the control center of the cell, containing the cell's genetic material (DNA) and regulating gene expression.

Front

What is a vacuole?

Back

A vacuole is a membrane-bound sac within a cell that stores substances such as nutrients, waste products, or water.

Front

What is the difference between plant and animal cells?

Back

Plant cells have a cell wall, chloroplasts, and large central vacuoles, while animal cells have only a cell membrane and smaller vacuoles.

Front

What is the function of ribosomes?

Back

Ribosomes are the sites of protein synthesis, where amino acids are assembled into proteins.

Front

What is the role of mitochondria?

Back

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