Which of the following features is/are present in mitochondria but not in chloroplasts?I. DNA and ribosomesII. Outer and inner membranesIII. Cristae
A
I only
B
II only
C
III only
D
I and III only
Explanation: 

Detailed explanation-1: -The inner membrane of mitochondria is thrown into various types of folds called cristae. Cristae are generally tubular in plant cells and plate like in animal and fungal cells. The inner mitochondrial membrane bears oxysomes, electron transport chains, succinate dehydrogenase and enzymes of fatty acid synthesis.

Detailed explanation-2: -Mitochondria are the “powerhouses” of the cell, breaking down fuel molecules and capturing energy in cellular respiration. Chloroplasts are found in plants and algae. They’re responsible for capturing light energy to make sugars in photosynthesis.

Detailed explanation-3: -Instead, DNA is also found in the mitochondria present in most plant and animals cells, as well as in the chloroplasts of plant cells.
