Cell structures

Front

What do lysosomes do?

Back

Lysosomes are organelles that contain enzymes to break down waste materials and cellular debris. They are often referred to as the 'clean-up crew' of the cell.

Front

What is the hydrophobic region of the cell membrane?

Back

The hydrophobic region of the cell membrane consists of the fatty acid tails of phospholipids, which repel water and help maintain the structure of the membrane.

Front

Which organelle produces energy for the cell?

Back

Mitochondria are known as the powerhouse of the cell, as they convert nutrients into energy (ATP) through cellular respiration.

Front

What is the function of the cell membrane?

Back

The cell membrane controls what enters and exits the cell, providing a barrier and maintaining homeostasis.

Front

Which organelle packages and distributes proteins?

Back

Golgi Bodies receive proteins and materials from the endoplasmic reticulum (ER), modify them, and send them to their destinations.

Front

What is the role of the nucleus in a cell?

Back

The nucleus acts 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 function of ribosomes?

Back

Ribosomes are responsible for protein synthesis, translating messenger RNA (mRNA) into polypeptide chains.

Front

What is the structure of the cell membrane?

Back

The cell membrane is composed of a phospholipid bilayer with embedded proteins, cholesterol, and carbohydrates, creating a fluid mosaic model.

Front

What are vacuoles?

Back

Vacuoles are storage organelles in cells that hold various substances, such as nutrients, waste products, or water.

Front

What is the endoplasmic reticulum (ER)?

Back

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