Front

What is the rough endoplasmic reticulum (RER)?

Back

The rough endoplasmic reticulum is a type of endoplasmic reticulum that has ribosomes attached to its surface, giving it a 'rough' appearance. It is involved in protein synthesis and processing.

Front

What do ribosomes do?

Back

Ribosomes are cellular structures that synthesize proteins by translating messenger RNA (mRNA) into polypeptide chains.

Front

What are archeabacteria?

Back

Archeabacteria are a group of microorganisms that are prokaryotic and often live in extreme environments, such as hot springs and salt lakes.

Front

What is a cell?

Back

A cell is the basic structural and functional unit of all living organisms, often referred to as the building block of life.

Front

Are most protists unicellular or multicellular?

Back

Most protists are unicellular, but a few are multicellular.

Front

What type of cells contain many mitochondria?

Back

Muscle cells contain many mitochondria because they require a lot of energy for contraction.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell; they generate ATP through cellular respiration, providing energy for cellular activities.

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 are the main components of a cell membrane?

Back

The main components of a cell membrane are phospholipids, proteins, cholesterol, and carbohydrates.

Front

What is the role of the Golgi apparatus?

Back

The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.
