What did chloroplasts and mitochondria used to be?

What did chloroplasts and mitochondria used to be?

Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. Eukaryotic cells containing mitochondria then engulfed photosynthetic prokaryotes, which evolved to become specialized chloroplast organelles.

What is the importance of chloroplasts and mitochondria in our environment?

Chloroplasts (members of the plastid family) and mitochondria are central to the energy cycles of ecosystems and the biosphere. They both contain DNA, organized into nucleoids, coding for critical genes for photosynthetic and respiratory energy production.

Why plants need both chloroplasts and mitochondria?

Explanation: Chloroplasts are present in photosynthetic plants and is responsible for making the food of the plant. It is important to note that plants need both chloroplasts and mitochondria because without one organelle say the mitochondria the entire cell would be unable to carry out its life activities.

How do mitochondria and chloroplasts support endosymbiotic theory?

Explanation: Bacteria, a prokaryote, has circular DNA, as do mitochondria and chloroplasts. This provides support for the Endosymbiotic Theory, which states that the mitochondria and chloroplast in eukaryotic cells were once aerobic bacteria (prokaryote) that were ingested by a large anaerobic bacteria (prokaryote).

How does chloroplast and mitochondria work together?

-Chloroplasts convert the sunlight (absorbed by the chlorophyll) into food, and then mitochondria make/produce energy out of the food in the form of ATP.

What is the function of the mitochondria Why do plants need both a chloroplasts and mitochondria quizlet?

Cells need both chloroplasts and mitochondria to undergo both photosynthesis AND cell respiration. After photosynthesis, which chloroplasts are needed for, which yields oxygen and glucose, plants need to break down the glucose and they use cell respiration to do this, which happens in the mitochondria.
