Cell Organelles

Front

What is the function of the cell wall?

Back

The cell wall provides structural support and protection to the cell, and is found in plant cells, fungi, and some bacteria, but not in animal cells.

Front

What distinguishes eukaryotic cells from prokaryotic cells?

Back

Eukaryotic cells have a defined nucleus and membrane-bound organelles, while prokaryotic cells do not.

Front

What is the structure and function of the cell membrane?

Back

The cell membrane is a double layer of phospholipids that acts as a barrier, controlling the movement of substances in and out of the cell (selectively permeable).

Front

What is the role of the nucleus in a cell?

Back

The nucleus contains the cell's genetic material (DNA) and is responsible for regulating gene expression and cell division.

Front

What are ribosomes and what is their function?

Back

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

Front

What is the difference between plant and animal cells regarding organelles?

Back

Plant cells have a cell wall, chloroplasts, and large central vacuoles, while animal cells do not have these structures.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are organelles 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 involved in the synthesis of proteins (rough ER) and lipids (smooth ER), and in the transport of materials within the cell.

Front

What is the purpose of the Golgi apparatus?

Back

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

Front

What is the function of lysosomes?

Back

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