,1. Multiple Choice: Which organelle is primarily involved in
the synthesis of oils, phospholipids, and steroids?
- A) Ribosome
- B) Smooth Endoplasmic Reticulum
- C) Lysosome
- D) Mitochondrion
Answer: B) Smooth Endoplasmic Reticulum
Rationale: The smooth endoplasmic reticulum is
responsible for the synthesis of lipids, including oils,
phospholipids, and steroids.
2. Fill-in-the-Blank: The process by which a cell engulfs
foreign particles is known as __________.
Answer: Phagocytosis
Rationale: Phagocytosis is the process by which a cell
engulfs large particles or cells, either to destroy them, to
feed on them, or to get information from them.
3. True/False: Mitochondria are found only in animal cells.
Answer: False
Rationale: Mitochondria are found in most eukaryotic
cells, including plants and fungi, not just in animal cells.
, Rationale: The cytoskeleton maintains the cell's shape,
secures organelles in specific positions, allows cytoplasm
and vesicles to move within the cell, and enables unicellular
organisms to move independently.
5. Multiple Choice: What is the primary function of the
nucleolus?
- A) DNA replication
- B) Cell division
- C) Ribosome production
- D) Protein synthesis
Answer: C) Ribosome production
Rationale: The nucleolus is the site of ribosomal RNA
synthesis and ribosome assembly.
6. Fill-in-the-Blank: Proteins that are destined for secretion
are typically synthesized in the __________.
Answer: Rough Endoplasmic Reticulum
Rationale: The rough endoplasmic reticulum is studded
with ribosomes and is the site where proteins destined for
export are synthesized.
7. True/False: All cells have a cell wall.
Answer: False
Rationale: Only plant cells and some prokaryotes have a
cell wall; animal cells do not.
