Understanding Endosymbiosis Theory

What is the basic premise of the endosymbiosis theory?

• Eukaryotic cells evolved independently.

• Prokaryotic cells engulfed eukaryotic cells.

• Eukaryotic cells engulfed prokaryotic cells.

• Prokaryotic cells evolved into eukaryotic cells.

Which type of cell is more complex?

• Prokaryotic cell

• Eukaryotic cell

• Neither, they are simple

• Both are equally complex

What mnemonic device can help remember the complexity of eukaryotic cells?

• You carry organelles

• You means simple

• Pro means complex

• Pro means nucleus

What process allows eukaryotic cells to engulf prokaryotic cells?

• Exocytosis

• Photosynthesis

• Endocytosis

• Mitosis

What is the result of eukaryotic cells engulfing prokaryotic cells over time?

• Destruction of prokaryotic cells

• Formation of simpler organisms

• No significant change

• Evolution into more complex organisms

Which organelle is known as the powerhouse of the cell?

• Nucleus

• Mitochondria

• Ribosome

• Chloroplast

What is the primary function of chloroplasts in plant cells?

• Energy production

• Cell division

• Photosynthesis

• Protein synthesis

What are the three elements that allow mitochondria and chloroplasts to be free-living?

• Membrane, cytoplasm, nucleus

• Chlorophyll, ATP, photosynthesis

• Ribosomes, DNA, replication ability

• Cell wall, nucleus, ribosomes

What color is associated with chlorophyll in plants?

• Green

• Red

• Blue

• Yellow

What is the significance of the endosymbiosis theory?

• It outlines the structure of DNA.

• It describes the evolution of complex organisms.

• It explains the origin of prokaryotic cells.

• It details the process of cell division.
