Structure of Cells

Which of the following is a characteristic of prokaryotic cells?

• Nucleus

• Mitochondria

• Cell wall

• Endoplasmic reticulum

Answer explanation

Prokaryotic cells have a cell wall.

Eukaryotic cells are typically found in:

• Bacteria

• Archaea

• Animals

• Viruses

Answer explanation

Eukaryotic cells are typically found in animals.

Which structure is present in eukaryotic cells but not in prokaryotic cells?

• Ribosomes

• DNA

• Nucleus

• Cytoplasm

Answer explanation

The nucleus is a structure found in eukaryotic cells but not in prokaryotic cells. It contains the cell's DNA and controls cellular activities.

Prokaryotic cells reproduce by:

• Mitosis

• Meiosis

• Binary fission

• Budding

Answer explanation

Prokaryotic cells reproduce by binary fission, where a single cell divides into two identical daughter cells.

Which of the following organelles is found only in eukaryotic cells?

• Golgi apparatus

• Chloroplast

• Both A and B

• None of the above

Answer explanation

The Golgi apparatus and chloroplast are organelles found only in eukaryotic cells. Therefore, the correct answer is Both A and B.

Prokaryotic cells do not have:

• DNA

• A cell membrane

• A nucleus

• Ribosomes

Answer explanation

Prokaryotic cells lack a nucleus, which is a defining characteristic of eukaryotic cells.

Eukaryotic cells are generally:

• Smaller than prokaryotic cells

• The same size as prokaryotic cells

• Larger than prokaryotic cells

• Variable in size

Answer explanation

Eukaryotic cells are larger than prokaryotic cells. They have a more complex structure and contain a nucleus.

Which of the following is true about prokaryotic cells?

• They have multiple chromosomes.
• Their DNA is not enclosed within a membrane.
• They have a well-defined nucleus.
• They contain mitochondria.

Discuss, how the concept of change is evident in the evolution from prokaryotic to eukaryotic cells.

Suggest, how does the structural simplicity of prokaryotic cells relate to their efficiency as a system?
