18 Questions
What is a distinguishing feature of eukaryotic cells compared to prokaryotic cells?
Presence of membrane-bound organelles
Which organelles are visible only with an electron microscope?
Lysosomes
What is the function of endoplasmic reticulum in a cell?
Cytoplasmic framework providing a surface for biochemical activities
Which organelle is responsible for carrying out crucial functions in cells?
Plastids
How do large and complex cells maintain different chemical activities separate from each other?
Through membrane-bound organelles
In terms of size, how do eukaryotic cells generally compare to prokaryotic cells?
Eukaryotic cells are generally larger than prokaryotic cells
What is a major difference in size between prokaryotic and eukaryotic cells?
Prokaryotic cells are generally smaller, while eukaryotic cells are generally larger.
How is the nuclear region in a eukaryotic cell different from that in a prokaryotic cell?
The nuclear region in eukaryotic cells is well defined and surrounded by a nuclear membrane.
Which type of cells typically have a single chromosome?
Prokaryotic cells
What is a key difference between prokaryotic and eukaryotic cells in terms of organelles?
Prokaryotic cells lack most of the cytoplasmic organelles present in eukaryotic cells.
Which statement best describes the organelles in prokaryotic cells?
Prokaryotic cells have no organelles.
What is the function of the cytoplasm in a cell?
To contain the fluid content inside the plasma membrane.
What vital function do endoplasmic reticulum (ER) serve in eukaryotic cells?
They help in the manufacture of fat molecules important for cell function.
Which statement accurately describes the role of membranes in cells?
Eukaryotic cells have nuclear membrane and membrane-enclosed organelles.
How does rough endoplasmic reticulum (RER) differ from smooth endoplasmic reticulum (SER) in terms of appearance?
RER looks rough under a microscope due to ribosomes, while SER looks smooth.
Which type of cells associate chlorophyll with membranous vesicles?
Prokaryotic cells
What distinguishes eukaryotic cells from prokaryotic cells based on their chromosome organization?
Prokaryotic cells have nucleoids instead of a defined nucleus.
Why do viruses lack characteristics of life until they enter a living body?
Viruses need to use cell machinery from living bodies to show characteristics of life
