What is the function of the mitochondrion in a cell?

Back

The mitochondrion is known as the powerhouse of the cell, as it releases energy through the process of cellular respiration.

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 main function of the nucleus in a cell?

Back

The nucleus serves as the control center of the cell, housing the cell's DNA and coordinating activities such as growth, metabolism, and reproduction.

Front

What is the structure and function of the cell wall?

Back

The cell wall is a rigid outer layer found in plant cells, providing structural support and protection.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the sites of protein synthesis, where amino acids are assembled into proteins based on the instructions from mRNA.

Front

What is the endoplasmic reticulum (ER) and its types?

Back

The endoplasmic reticulum is a network of membranes involved in protein and lipid synthesis. It has two types: rough ER (with ribosomes) and smooth ER (without ribosomes).

Front

What is the function 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.

Front

What is the role of vacuoles in plant cells?

Back

Vacuoles are large storage sacs that hold water, nutrients, and waste products, helping maintain turgor pressure in plant cells.

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.
