Understanding Eukaryotic Cell Organelles

What are organelles and why are they important in eukaryotic cells?

• They are only found in animal cells.

• They are the same as prokaryotic cells.

• They are structures within cells that perform specific functions.

• They are the smallest unit of life.

Which of the following best describes the function of the nucleus?

• It is the powerhouse of the cell.

• It stores water and nutrients.

• It packages proteins for secretion.

• It controls all cell activities.

What structural feature is unique to the mitochondrion?

• Thylakoid stacks.

• A large central vacuole.

• A double membrane with cristae.

• A single membrane.

What is the primary function of the mitochondrion?

• Photosynthesis.

• Protein synthesis.

• Energy production through aerobic respiration.

• Storage of genetic information.

Which pigment is crucial for the chloroplast's function in photosynthesis?

• Xanthophyll.

• Carotene.

• Anthocyanin.

• Chlorophyll.

Why can't animal cells perform photosynthesis?

• They lack mitochondria.

• They do not have chloroplasts.

• They lack a cell membrane.

• They do not have a nucleus.

What is the primary role of the vacuole in plant cells?

• Photosynthesis.

• Maintaining cell shape and osmotic balance.

• Protein synthesis.

• Energy production.

What is the function of the Golgi body in a cell?

• It produces ribosomal RNA.

• It synthesizes lipids.

• It packages and secretes proteins and carbohydrates.

• It stores genetic material.

What distinguishes the rough ER from the smooth ER?

• The smooth ER is involved in protein synthesis, while the rough ER is not.

• The rough ER is involved in lipid synthesis, while the smooth ER is not.

• The smooth ER has ribosomes, while the rough ER does not.

• The rough ER has ribosomes, while the smooth ER does not.

What is the primary function of the endoplasmic reticulum?

• Energy production.

• Transport of materials within the cell.

• Photosynthesis.

• Storage of water and nutrients.
