What is the primary function of mitochondria in a cell?

Back

Mitochondria are responsible for producing ATP (adenosine triphosphate), which is the energy currency of the cell.

Front

What type of organisms are classified as prokaryotes?

Back

Prokaryotes are single-celled organisms that lack a nucleus, and they are primarily represented by bacteria.

Front

What is the role of the nucleus in a cell?

Back

The nucleus holds the cell's DNA and is responsible for regulating gene expression and cell division.

Front

Front

What is the function of vacuoles in plant cells?

Back

Vacuoles store water, nutrients, and waste products, and they help maintain turgor pressure in plant cells.

Front

How do mitochondria and chloroplasts differ in function?

Back

Mitochondria generate ATP through cellular respiration, while chloroplasts convert light energy into chemical energy through photosynthesis.

Front

What is the significance of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is the structure that surrounds the nucleus called?

Back

The nuclear envelope is the double membrane that surrounds the nucleus.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis by translating messenger RNA (mRNA) into polypeptides.

Front

What organelle is involved in the modification and packaging of proteins?

Back

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