What is differentiation in biology?

Back

Differentiation is the process by which cells become specialized in structure and function, allowing them to perform specific roles in an organism.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are organelles in plant cells that conduct photosynthesis, converting light energy into chemical energy in the form of glucose.

Front

How do muscle cells differ from blood cells?

Back

Muscle cells and blood cells differ because different genes are activated in each type of cell, leading to distinct structures and functions.

Front

What is the significance of DNA activation in cell differentiation?

Back

During differentiation, specific parts of the DNA are activated, which determines the structure and function of the cell, allowing for specialization.

Front

What structure is unique to plant cells and not found in animal cells?

Back

The cell wall is a structure found in plant cells that provides support and protection, which is absent in animal cells.

Front

What is the primary function of mitochondria in cells?

Back

Mitochondria are known as the powerhouse of the cell, as they generate ATP through cellular respiration, providing energy for cellular activities.

Front

What is the process by which nerve and muscle cells develop from a fertilized egg?

Back

The process is called differentiation, where cells develop into specialized types based on gene expression.

Front

What is the function of vacuoles in plant cells?

Back

Vacuoles are storage organelles in plant cells that hold various substances, including nutrients, waste products, and water.

Front

What is the main purpose of photosynthesis?

Back

The main purpose of photosynthesis is to convert light energy into chemical energy stored in glucose, which plants use for growth and energy.

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.
