What is a chloroplast?

Back

A chloroplast is an organelle found in plant cells that is responsible for photosynthesis, converting sunlight into energy.

Front

What is the function of a cell membrane?

Back

The cell membrane is a protective barrier that regulates what enters and exits the cell, maintaining homeostasis.

Front

What is the Golgi Body?

Back

The Golgi Body is an organelle that modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What makes the endoplasmic reticulum rough?

Back

The rough endoplasmic reticulum is studded with ribosomes, which are the sites of protein synthesis.

Front

Where are proteins made in the cell?

Back

Proteins are made in the ribosomes, which can be found free in the cytoplasm or attached to the rough endoplasmic reticulum.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are responsible for synthesizing proteins by translating messenger RNA (mRNA) into polypeptide chains.

Front

What is the difference between plant and animal cells?

Back

Plant cells have chloroplasts, a cell wall, and large vacuoles, while animal cells do not.

Front

What is the function of vacuoles in plant cells?

Back

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

Front

What is the structure of the plasma membrane?

Back

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

Front

What is the function of the nucleus?

Back

The nucleus houses the cell's genetic material (DNA) and controls cellular activities by regulating gene expression.
