B2.2 Cell Organelles and Compartmentalization (SL)

Front

What is the advantage of separating the nucleus and cytoplasm in eukaryotic cells?

Back

Regulation of gene expression.

Front

How did the development of ultracentrifuges and cell fractionation techniques contribute to our understanding of organelles?

Back

Allowed isolation and study of individual organelles.

Front

What would be the consequences if mRNA immediately met ribosomes in eukaryotic cells, similar to prokaryotic cells?

Back

Less precise control over gene expression.

Front

Why is post-transcriptional modification of RNA not possible in prokaryotic cells?

Back

Lack of nuclear membrane.

Front

Why isn't the cytoplasm considered an organelle?

Back

It is not specialized to perform a specialized function.

Front

Define eukaryotic cells.

Back

Cells that have a nucleus enclosed within membranes, unlike prokaryotic cells.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis.

Front

What role does the nuclear membrane play in eukaryotic cells?

Back

It separates the nucleus from the cytoplasm, regulating the passage of materials.

Front

Explain the significance of compartmentalization in eukaryotic cells.

Back

Compartmentalization allows for specialized environments for different cellular processes.

Front

What is the function of the endoplasmic reticulum?

Back

It synthesizes proteins and lipids and transports them within the cell.
