Endosymbiotic Theory

How do mitochondria and chloroplasts replicate?

• They divide in a way similar to how prokaryote cells divide.

• They replicate through binary fission like bacteria.

• They undergo mitosis like eukaryotic cells.

• They replicate by budding off from the parent cell.

What evidence supports the endosymbiotic theory?

• Mitochondria and chloroplasts have their own DNA, similar to bacterial DNA.

• Mitochondria and chloroplasts are the same size as prokaryotic cells.

• Mitochondria and chloroplasts can replicate independently of the cell.

• Mitochondria and chloroplasts have ribosomes similar to those found in eukaryotic cells.

What is the main difference between prokaryote and eukaryote cells?

• Prokaryote cells have no true nuclei, while eukaryote cells do.

• Eukaryote cells are smaller than prokaryote cells.

• Prokaryote cells have membrane-bound organelles, while eukaryote cells do not.

• Eukaryote cells reproduce asexually, while prokaryote cells reproduce sexually.

What is the role of chloroplasts in eukaryotic cells?

• Chloroplasts are responsible for photosynthesis, converting sunlight into energy.

• Chloroplasts are involved in cellular respiration and energy production.

• Chloroplasts help in the synthesis of proteins and enzymes.

• Chloroplasts are responsible for storing genetic information.

What is the significance of the endosymbiotic theory in biology?

• It explains the origin of eukaryotic cells and their complex structures.

• It describes the process of natural selection in species.

• It outlines the stages of cellular respiration in prokaryotes.

• It provides a framework for understanding genetic mutations.

What did the bacteria that used sunlight energy to produce their own food evolve into?

• Mitochondria

• Chloroplasts

• Nucleus

• Ribosomes

What are mitochondria?

• Organelles that generate ATP through cellular respiration.

• Structures that store genetic information in cells.

• Components responsible for protein synthesis in cells.

• Cellular structures that provide structural support to the cell.

What is a key characteristic of prokaryote cells?

• They have a nucleus.

• They lack membrane-bound organelles.

• They are larger than eukaryotic cells.

• They reproduce sexually.

What is the function of ribosomes in cells?

• Ribosomes are responsible for energy production.

• Ribosomes are responsible for protein synthesis.

• Ribosomes are responsible for DNA replication.

• Ribosomes are responsible for cell division.

What is the importance of ATP in cellular processes?

• ATP serves as the primary energy currency of the cell.

• ATP is a structural component of DNA.

• ATP is involved in the synthesis of proteins.

• ATP acts as a signaling molecule in the cell.
