Biology Cell structures assessment

Front

What is the function of the cell membrane?

Back

The cell membrane is responsible for deciding what enters and leaves the cell due to its selectively permeable nature.

Front

Describe the structure of the cell membrane.

Back

The cell membrane is made up of a phospholipid bilayer with hydrophilic heads facing outward and hydrophobic tails facing inward, creating a barrier that keeps water out.

Front

What role do centrioles play in cell division?

Back

Centrioles are organelles that help pull chromosomes apart during cell division by releasing spindle fibers.

Front

What can be inferred about a cell that lacks centrioles?

Back

The cell cannot divide because it lacks centrioles.

Front

Which organelle is least useful for protein synthesis in animal cells?

Back

Chloroplasts are least useful for protein synthesis in animal cells.

Front

What happens to a plant cell when water pressure changes?

Back

The cell wall helps the plant cell maintain its shape when water pressure changes.

Front

What is the composition of the cell membrane?

Back

The cell membrane is composed of a phospholipid bilayer, proteins, cholesterol, and carbohydrates.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are responsible for synthesizing proteins by translating messenger RNA.

Front

What is the function of the endoplasmic reticulum?

Back

The endoplasmic reticulum is involved in the synthesis of proteins and lipids, and it also helps in the transport of materials within the cell.

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.
