The endosymbiotic theory helps to explain the origin of which structures?

Biology

The answer is <span>A)mitochondria
</span>

<span>The endosymbiotic theory explains that mitochondria and chloroplasts descended from the same type of bacteria. Symbiosis is an interaction between two organisms of different species, and endosymbiosis is a type of symbiosis in which one organism lives inside the other one. According to the endosymbiotic theory, a host cell ingested symbiotic bacteria, which specialised into mitochondria or chloroplasts. The evidence for this theory is that mitochondria and chloroplasts, like bacteria, have their own circular DNA. and They also have their own transcriptional and translational machinery.</span>

Which of these CORRECTLY explains the difference between the processes of photosynthesis and respiration?
Anastasy [175]

Answer:

The correct answer would be C) The Calvin cycle takes place only in the chloroplast.

The major difference between photosynthesis and respiration is that photosynthesis takes place only in plants while respiration takes place in all the living organisms including plants and humans.

Green plants and few bacteria contain special organelle called chloroplast which enables them to perform photosynthesis.

Hence, Calvin cycle (light independent phase of photosynthesis) takes place only in plants that too in chloroplasts.

In contrast, Krebs cycle usually takes place in mitochondria in both plants and animals and glycolysis takes place in the cytoplasm of the cell.

The electron transport chain takes place in mitochondria in animals whereas in plants it takes place in both mitochondria and thylakoid membrane.
