Front

What is the Smooth Endoplasmic Reticulum (Smooth ER)?

Back

A type of endoplasmic reticulum that is involved in the synthesis of lipids and detoxification of drugs.

Front

What is a eukaryotic cell?

Back

A cell that has a nucleus and membrane-bound organelles, such as plant and animal cells.

Front

What is cell theory?

Back

A fundamental concept in biology stating that all living organisms are composed of cells, and all cells arise from pre-existing cells.

Front

What is facilitated diffusion?

Back

A passive transport process that allows substances to cross membranes with the assistance of special proteins.

Front

What is the Golgi body?

Back

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

Front

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

Back

It is involved in the synthesis of proteins that are secreted from the cell or incorporated into the cell's plasma membrane.

Front

What is active transport?

Back

The movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is a prokaryotic cell?

Back

A simple, unicellular organism that lacks a nucleus and membrane-bound organelles, such as bacteria.

Front

What is the role of mitochondria?

Back

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

Front

What is a vacuole?

Back

A membrane-bound organelle in cells that stores nutrients, waste products, and helps maintain turgor pressure in plant cells.
