Cell Structure and Function Concepts

What are the three common components found in all cells, regardless of their type?

• Cell wall, nucleus, cytoplasm

• Cell membrane, cytoplasm, DNA

• Mitochondria, chloroplast, cell membrane

• Nucleus, DNA, cell wall

Which type of cell is characterized by the presence of a nucleus and membrane-bound organelles?

• Prokaryotic cell

• Bacterial cell

• Eukaryotic cell

• Unicellular organism

What is a distinguishing feature of prokaryotic cells compared to eukaryotic cells?

• They are always multicellular

• They contain a nucleus

• They lack membrane-enclosed organelles

• They are found in plants and animals

What is the primary role of organelles within a cell?

• To provide structural support to the cell

• To store genetic material

• To perform unique and specialized functions

• To regulate cell division

What is the primary function of the nucleus in a eukaryotic cell?

• Protein synthesis

• Energy production

• Waste disposal

• Controlling cell activities

What is chromatin?

• A type of protein

• The condensed form of DNA during cell division

• The tangled, spread-out form of DNA

• A component of the cell membrane

Where are ribosomes primarily made within the cell?

• Cytoplasm

• Endoplasmic reticulum

• Nucleolus

• Golgi apparatus

What is the jelly-like substance where organelles float within a cell?

• Nucleoplasm

• Cytoplasm

• Cell sap

• Protoplasm

What distinguishes rough endoplasmic reticulum (rER) from smooth endoplasmic reticulum (sER)?

• rER synthesizes lipids, sER synthesizes proteins

• rER has ribosomes attached, sER has ribosomes attached

• rER stores water, sER stores waste

• rER has ribosomes attached, sER does not

What are the small, membrane-bound sacs that transport proteins and other materials from the endoplasmic reticulum?

• Lysosomes

• Vacuoles

• Vesicles

• Mitochondria
