6
Which of the following lacks membrane-bound cells?
A
Neither eukaryotic cells nor prokaryotic cells
B
Only eukaryotic cells
C
Both eukaryotic cells and prokaryotic cells
D
Only prokaryotic cells
▼ View Solution
✓ Answer:
D
Only prokaryotic cells
Prokaryotic cells lack membrane-bound organelles such as a true nucleus, mitochondria and endoplasmic reticulum.
7
Which of the following options is correct regarding nuclear membrane and other organelles in cells?
A
Nuclear membrane is present in prokaryotic cells
B
Nuclear membrane is absent in prokaryotic cells
C
Nuclear membrane is absent in eukaryotic cells
D
Most of the cytoplasmic organelles are present in prokaryotic cells
▼ View Solution
✓ Answer:
B
Nuclear membrane is absent in prokaryotic cells
Prokaryotic cells lack a true nucleus and nuclear membrane, whereas eukaryotic cells have a membrane-bound nucleus.
8
Which of the following substances can move across the cell membrane by diffusion?
A
Oxygen
B
Nucleic acid
C
Protein
D
Starch
▼ View Solution
✓ Answer:
A
Oxygen
Oxygen is a small nonpolar molecule and can diffuse through the lipid bilayer of the cell membrane.
9
Plasma membrane is made up of ____.
A
Only protein
B
Only cellulose
C
Both protein and lipid
D
Only lipid
▼ View Solution
✓ Answer:
C
Both protein and lipid

Four
B
Twenty four
C
Sixteen
D
Eight
▼ View Solution
✓ Answer:
A
Four
