Cell Theory & Organelle Review (open notes_minor grade)

Front

What is the Cell Theory?

Back

The Cell Theory states that all living organisms are composed of cells, cells are the basic unit of life, and all cells arise from pre-existing cells.

Front

What are the main differences between plant and animal cells?

Back

Plant cells have a cell wall, chloroplasts, and large central vacuoles, while animal cells do not have a cell wall and have smaller vacuoles.

Front

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 structural support.

Front

What is a cell wall and which organisms have it?

Back

A cell wall is a rigid outer layer that provides support and protection to the cell. It is found in plant cells, fungi, and some bacteria.

Front

What are organelles?

Back

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

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 in a cell?

Back

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

Front

How do you identify a plant cell under a microscope?

Back

A plant cell can be identified by the presence of a cell wall and chloroplasts, which are not found in animal cells.

Front

What is the function of the vacuole in plant cells?

Back

The vacuole stores nutrients, waste products, and helps maintain turgor pressure in plant cells.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells do.
