Prokaryotic & Eukaryotic, Cell theory

Front

What are prokaryotic cells?

Back

Prokaryotic cells are simple, single-celled organisms that lack a nucleus and membrane-bound organelles. Examples include bacteria.

Front

What are eukaryotic cells?

Back

Eukaryotic cells are complex cells that have a nucleus and membrane-bound organelles. They can be single-celled or multicellular, such as plants and animals.

Front

What is the cell theory?

Back

The cell theory states that all living organisms are made up of cells, cells are the basic unit of life, and all cells come from pre-existing cells.

Front

What is an autotroph?

Back

An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Examples include plants.

Front

What is a heterotroph?

Back

A heterotroph is an organism that cannot produce its own food and must consume other organisms for energy. Examples include animals.

Front

What is the main difference between prokaryotic and eukaryotic cells?

Back

The main difference is that prokaryotic cells do not have a nucleus, while eukaryotic cells do.

Front

What type of organisms are bacteria classified as?

Back

Bacteria are classified as prokaryotic organisms.

Front

Can eukaryotic cells be multicellular?

Back

Yes, eukaryotic cells can be multicellular, as seen in plants and animals.

Front

What is the function of the nucleus in eukaryotic cells?

Back

The nucleus contains the cell's genetic material (DNA) and controls the cell's activities.

Front

What are membrane-bound organelles?

Back

Membrane-bound organelles are specialized structures within eukaryotic cells that perform specific functions, such as mitochondria and the endoplasmic reticulum.
