Cell Structures and Function

Front

What is the function of the cell wall?

Back

The cell wall provides structural support and protection to the cell, and it helps maintain cell shape.

Front

What is the primary function of the cytoplasm?

Back

The cytoplasm is a gel-like fluid that fills the cell and holds organelles in place, facilitating cellular processes.

Front

What organelle is known as the powerhouse of the cell?

Back

Mitochondria are known as the powerhouse of the cell because they produce energy (ATP) through cellular respiration.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts capture sunlight and convert it into chemical energy through photosynthesis, producing glucose.

Front

What is the process of photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What are the main components of the cell membrane?

Back

The cell membrane is primarily composed of a phospholipid bilayer, proteins, cholesterol, and carbohydrates.

Front

How do mitochondria contribute to cellular respiration?

Back

Mitochondria convert biochemical energy from nutrients into ATP, which is used as energy currency in cells.

Front

What is the significance of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis, translating messenger RNA (mRNA) into polypeptide chains.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and various organelles.

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), as well as the transport of materials within the cell.
