Cell Organelles

Front

What are organelles?

Back

Organelles are tiny structures within a cell that carry out specific functions necessary for the cell's life and activities.

Front

What is cytoplasm?

Back

Cytoplasm is the jellylike substance that fills the space between the cell membrane, organelles, and the nucleus, providing a medium for biochemical reactions.

Front

What is the function of ribosomes?

Back

Ribosomes are small organelles that function as factories for protein synthesis; they can be found floating in the cytoplasm or attached to the endoplasmic reticulum (E.R.).

Front

What is the role of the nucleus in a cell?

Back

The nucleus is the control center of the cell, directing all cellular activities and containing the cell's genetic material.

Front

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

Back

Mitochondria are known as the 'powerhouse' of the cell because they convert energy from food molecules into usable energy (ATP) for the cell.

Front

What is the function of the cell membrane?

Back

The cell membrane protects the cell and regulates what enters and exits the cell, maintaining homeostasis.

Front

What is the endoplasmic reticulum (E.R.)?

Back

The endoplasmic reticulum (E.R.) is a network of membranes involved in protein and lipid synthesis; it comes in two forms: rough (with ribosomes) and smooth (without ribosomes).

Front

What is the role of lysosomes in a cell?

Back

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

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 are chloroplasts and their function?

Back

Chloroplasts are organelles found in plant cells that conduct photosynthesis, converting light energy into chemical energy (glucose).
