Honors - Cells & Organelles

Front

What is a Ribosome?

Back

A ribosome is a cellular structure that synthesizes proteins by translating messenger RNA (mRNA). It can be found floating freely in the cytoplasm or attached to the endoplasmic reticulum.

Front

What is the nuclear membrane?

Back

The nuclear membrane, also known as the nuclear envelope, is a double-layered membrane that surrounds the nucleus of a cell, protecting its contents and regulating the passage of materials in and out.

Front

What is the function of a cell wall?

Back

The cell wall is a rigid outer layer that provides protection and support to plant cells, helping to maintain their shape and prevent excessive water loss.

Front

What is the cell membrane?

Back

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

Front

What is a Vacuole?

Back

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

Front

What is the function of Mitochondria?

Back

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

Front

What is the role of the Golgi Apparatus?

Back

The Golgi apparatus is responsible for modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles.

Front

What is Cytoplasm?

Back

Cytoplasm is the jelly-like substance within the cell membrane that contains organelles, cytoskeleton, and various molecules, facilitating cellular processes.

Front

What is Chloroplast?

Back

Chloroplasts are organelles found in plant cells that conduct photosynthesis, converting light energy into chemical energy stored in glucose.

Front

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

Back

The endoplasmic reticulum is a network of membranes involved in the synthesis of proteins (rough ER) and lipids (smooth ER), as well as the transport of materials within the cell.
