Unit 4A: Cell Types & Organelles

Front

What is a Prokaryote?

Back

A single-celled organism that lacks a membrane-bound nucleus and organelles, and has DNA that is not enclosed within a nuclear membrane.

Front

What is the function of the Rough Endoplasmic Reticulum?

Back

It makes and transports proteins within the cell.

Front

What is the role of Lysosomes in a cell?

Back

Lysosomes use enzymes to digest bacteria, viruses, and old organelles, recycling old cell parts.

Front

What is the primary function of Mitochondria?

Back

Mitochondria convert chemical energy stored in food into ATP, which is more convenient for the cell to use.

Front

True or False: Both prokaryotes and eukaryotes have ribosomes and a plasma membrane.

Back

True.

Front

What is a Eukaryote?

Back

An organism whose cells contain a nucleus and other membrane-bound organelles.

Front

What is the function of the Golgi Apparatus?

Back

The Golgi Apparatus modifies, sorts, and ships proteins and lipids to their destinations.

Front

What is the role of the Plasma Membrane?

Back

The Plasma Membrane controls the movement of substances in and out of the cell.

Front

What is the function of Vacuoles in plant cells?

Back

Vacuoles store food, water, or wastes and help maintain turgor pressure in plant cells.

Front

What is the function of Ribosomes?

Back

Ribosomes are the sites of protein synthesis in the cell.
