What is a cell?

A cell is the basic unit of life, the smallest structure capable of performing all functions necessary for life.

What are prokaryotic cells?

Prokaryotic cells are single-celled organisms that lack a nucleus and membrane-bound organelles.

What are eukaryotic cells?

Eukaryotic cells are complex cells with a nucleus and membrane-bound organelles, which can be unicellular or multicellular.

What is the function of the cell membrane?

The cell membrane controls what enters and exits the cell, providing protection and structural support.

What is the nucleus?

The nucleus is the organelle that contains the cell's genetic material and controls cellular activities.

What is cytoplasm?

Cytoplasm is the jelly-like substance inside the cell that contains organelles and is the site of many metabolic processes.

What are ribosomes?

Ribosomes are the cellular structures responsible for protein synthesis, found either free in the cytoplasm or attached to the endoplasmic reticulum.

What is the function of mitochondria?

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

What is the role of lysosomes?

Lysosomes contain digestive enzymes that break down waste materials and cellular debris.

What is the endoplasmic reticulum?

The endoplasmic reticulum is a network of membranes involved in protein and lipid synthesis; it comes in two forms: rough and smooth.
