Unit 3: Cell Theory, Structures, Specialized Cells

Front

What is the Cell Theory?

Back

The Cell Theory states that all living things are made up of cells, cells are the basic unit of life, and all cells come from pre-existing cells.

Front

What is the function of the Rough Endoplasmic Reticulum (Rough ER)?

Back

The Rough ER has ribosomes on its surface and is responsible for the synthesis and packaging of proteins.

Front

What is the role of the Golgi Apparatus in a cell?

Back

The Golgi Apparatus processes, sorts, and ships proteins received from the Endoplasmic Reticulum.

Front

What are organelles?

Back

Organelles are specialized structures within a cell that perform distinct functions to help the cell operate.

Front

What is the order of the major levels of organization in the body?

Back

The order is: cells, tissues, organs, organ systems, and the organism.

Front

What distinguishes prokaryotic cells from eukaryotic cells?

Back

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

Front

What is the function of mitochondria?

Back

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

Front

What is the function of chloroplasts?

Back

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

Front

What is the function of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is the difference between plant and animal cells?

Back

Plant cells have a cell wall and chloroplasts, while animal cells do not.
