Front

What are mitochondria believed to have originated from?

Back

Mitochondria are believed to have originated from aerobic bacteria through the process of endosymbiosis.

Front

What is the endosymbiotic theory?

Back

The endosymbiotic theory suggests that certain organelles, like mitochondria and chloroplasts, originated from free-living prokaryotes that were engulfed by ancestral eukaryotic cells.

Front

How do archaebacteria differ from eukaryotic cells?

Back

Archaebacteria are prokaryotic and lack a nucleus, while eukaryotic cells have a nucleus and membrane-bound organelles.

Front

Which two groups are most closely related: fungi and plants, or animals and gram positives?

Back

Fungi and plants are most closely related, as they share a more recent common ancestor.

Front

What are the characteristics of prokaryotic cells?

Back

Prokaryotic cells are unicellular, lack a nucleus, and have no membrane-bound organelles.

Front

What are the main types of prokaryotes?

Back

The main types of prokaryotes are bacteria and archaea.

Front

What role do mitochondria play in eukaryotic cells?

Back

Mitochondria are the powerhouse of the cell, responsible for producing ATP through cellular respiration.

Front

What is the function of chloroplasts in plant cells?

Back

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