Cell Components Flashcard

Front

What is the primary function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and structural support.

Front

What are ribosomes and where are they commonly found?

Back

Ribosomes are organelles that synthesize proteins and are often found attached to the endoplasmic reticulum (ER).

Front

What organelle is known as the powerhouse of the cell?

Back

The mitochondria are known as the powerhouse of the cell because they generate ATP, the energy currency of the cell.

Front

What is cytoplasm and what is its role in the cell?

Back

Cytoplasm is the jelly-like substance within the cell membrane that contains organelles and is the site for many metabolic processes.

Front

What is the function of vacuoles in a cell?

Back

Vacuoles store nutrients, waste products, and other materials; they are similar to a pantry in a kitchen.

Front

What is the structure of the cell membrane?

Back

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

Front

How do mitochondria contribute to cellular respiration?

Back

Mitochondria convert biochemical energy from nutrients into ATP through the process of cellular respiration.

Front

What is the difference between rough and smooth endoplasmic reticulum?

Back

Rough ER has ribosomes on its surface and is involved in protein synthesis, while smooth ER lacks ribosomes and is involved in lipid synthesis and detoxification.

Front

What role do lysosomes play in the cell?

Back

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

Front

What is the significance of the cytoskeleton in a cell?

Back

The cytoskeleton provides structural support, helps maintain cell shape, and facilitates movement within the cell.
