IB 1.2 Eukaryote structure

Which of the following are not membrane-bound organelles?

• Nucleoid

• Ribosomes

• Mitochondria

• Vacuole

• Golgi

The function of the [?] is to fold proteins that have been made by ribosomes.

Once the golgi has packaged a protein, which organelle takes the protein out of the cell?

• Vesicle

• Lysosome

• Endoplasmic reticulum

• Ribosome

How do eukaryotic ribosomes differ from prokaryotic ribosomes?

• Eukaryotic ribosomes are 70S whilst prokaryotic ribosomes are 80S.

• Eukaryotic ribosomes are 80S whilst prokaryotic ribosomes are 70S.

• Prokaryotic ribosomes are 80S whilst Eukaryotic ribosomes are 70S.

• In eukaryotes, some ribosomes are attached to the ER, whereas in prokaryotes they are not

Which organelle is represented in the image?

How does the appearance of lysosomes differ from that of vesicles?

• Lysosomes are larger than vesicles

• Vesicles are usually close to the golgi

• Vesicles appear colourless whereas lysosomes appear dark

• Vesicles transport proteins out of the cell whereas lysosomes have a digestive function

Which of these is the largest?

• Mitochondria

• Chloroplasts

Which of these is the largest?

• Nucleus

• Chloroplasts

Ciliated cells found in the respiratory system have tiny hairs on their surface which beat constantly. Which organelle supplies the energy for this?

Cells of the pancreas produce digestive enzymes for secretion into the small intestine. Which organelles would be required in abundance for this process?

• Mitochondria

• Endoplasmic reticulum

• Golgi

• Vesicles

• Lysosomes
