Unit 1A Cells

Front

What are eukaryotes?

Back

Eukaryotes are organisms whose cells have a nucleus enclosed within membranes, unlike prokaryotes, which do not have a nucleus.

Front

What are prokaryotic cells?

Back

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

Front

What is the function of the Golgi apparatus?

Back

The Golgi apparatus receives proteins and materials from the endoplasmic reticulum, packages them, and distributes them to their destinations.

Front

What is a vacuole?

Back

A vacuole is a membrane-bound organelle that stores materials such as water, salts, proteins, and carbohydrates.

Front

What are organelles?

Back

Organelles are specialized structures within a cell that perform distinct processes. They are found in eukaryotic 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.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are organelles that synthesize proteins by translating messenger RNA.

Front

What is the endoplasmic reticulum?

Back

The endoplasmic reticulum (ER) is a network of membranes involved in protein and lipid synthesis. It comes in two forms: rough ER (with ribosomes) and smooth ER (without ribosomes).

Front

What are lysosomes?

Back

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

Front

What is the cell membrane?

Back

The cell membrane is a protective barrier that surrounds the cell, controlling the movement of substances in and out.
