CP Comparing Cell Types & Endosymbiotic Theory

What is the main difference between prokaryotic and eukaryotic cells?

• Prokaryotic cells have a nucleus, while eukaryotic cells do not.

• Prokaryotic cells have membrane-bound organelles, while eukaryotic cells do not.

• Prokaryotic cells have linear chromosomes, while eukaryotic cells have circular DNA.

• Prokaryotic cells have a cell wall, while eukaryotic cells do not.

Which of the following is a characteristic of prokaryotic cells?

• Presence of a nucleus

• Linear chromosomes

• Membrane-bound organelles

• Circular DNA

What is the function of ribosomes in prokaryotic cells?

• Capture light energy and convert it into chemical energy

• Store water, nutrients, and waste products

• Make proteins

• Transport substances between different parts of the cell

Which of the following is a structure found in some prokaryotic cells?

• Chloroplasts

• Mitochondria

• Cell wall

• Nucleus

What is the main difference between plant and animal cells?

• Plant cells have a cell wall, while animal cells do not.

• Plant cells have mitochondria, while animal cells do not.

• Plant cells have a nucleus, while animal cells do not.

• Plant cells have membrane-bound organelles, while animal cells do not.

Which organelle is responsible for capturing light energy in plant cells?

• Chloroplasts

• Endoplasmic reticulum

• Golgi apparatus

What is the function of the cell wall in plant cells?

• Capture light energy and convert it into chemical energy

• Store water, nutrients, and waste products
