Front

What is the Golgi Apparatus?

Back

An organelle that modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

Define Nucleoid.

Back

A dense region of DNA in a prokaryotic cell.

Front

What are Pili?

Front

What is the Plasma Membrane?

Back

A phospholipid bilayer that surrounds the cell, controlling the movement of substances in and out.

Front

What is a Prokaryote?

Back

A single-celled organism without a nucleus or membrane-bound organelles.

Front

What is the function of Ribosomes?

Back

Organelles made of protein and RNA that direct protein synthesis.

Front

What is the difference between Prokaryotic and Eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while Eukaryotic cells have both.

Front

What is the role of the Rough Endoplasmic Reticulum (Rough ER)?

Back

It is involved in the synthesis and processing of proteins, studded with ribosomes.

Front

What is the function of Mitochondria?

Back

Organelles that produce energy (ATP) through cellular respiration.

Front

What is the Cytoplasm?

Back

The jelly-like substance within the cell membrane that contains organelles.
