What is the function of the Endoplasmic Reticulum in a cell?

Back

The Endoplasmic Reticulum (ER) is involved in the transportation of materials within the cell, including the synthesis of proteins and lipids.

Front

Why is the mitochondria referred to as the 'powerhouse' of the cell?

Back

Mitochondria are called the 'powerhouse' of the cell because they generate adenosine triphosphate (ATP), the energy currency of the cell, through cellular respiration.

Front

What is the primary function of chloroplasts in plant cells?

Back

Chloroplasts are responsible for photosynthesis, converting light energy into chemical energy stored in glucose.

Front

What is the role of the central vacuole in plant cells?

Back

The central vacuole stores nutrients and waste products, helps maintain turgor pressure, and plays a role in cell growth.

Front

What is the structure and function of the cell membrane?

Back

The cell membrane is the outermost layer of an animal cell, composed of a phospholipid bilayer that regulates the movement of substances in and out of the cell.

Front

What are the differences between plant and animal cells regarding organelles?

Back

Plant cells have chloroplasts and a central vacuole, while animal cells have lysosomes and centrioles.

Front

What is the significance of ribosomes in a cell?

Back

Ribosomes are the sites of protein synthesis, translating messenger RNA (mRNA) into polypeptide chains.

Front

How do lysosomes function within a cell?

Back

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

Front

What is the role of the Golgi apparatus in cellular processes?

Back

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

Front

What is the function of the cytoskeleton in a cell?

Back

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