Answer 1

Hint: Cristae are sub-compartments of the mitochondrial inner membrane and are critical to mitochondrial function. The powerhouses of the cell are also considered mitochondria because they are the organelles responsible for producing ATP, the cell 's energy currency.

Complete answer:
Changed centrioles that give rise to cilia and flagella are basal bodies. Apex is the basal body in the cell, which is the anchoring place for a flagellum.
Chlorophyll is present in high concentrations in plant cell chloroplasts. Chlorophyll, which helps plants to absorb energy from light, is essential for photosynthesis. In and around photosystems that are embedded in the thylakoid membranes of chloroplasts, chlorophyll molecules are precisely arranged.
The inner membrane of the mitochondrion, containing the cristae, folds inwards. These folds cause the mitochondrion to be packed with a much greater quantity of electron transport chain enzymes and ATP synthase. For inter-mitochondrial communication, Cristae junctions are also important. Cristae are parallel to each other and perpendicular to the relations between mitochondria of nearby mitochondria.
Similar to the action of protein enzymes, ribozymes (ribonucleic acid enzymes), often referred to as RNA molecules, can catalyse complex biochemical reactions. RNA can be both a genetic material (such as DNA) and protein enzymes can be a biological catalyst.

Hence, the correct answer is option (A).

Note: In several human diseases and during programmed cell death, irregular inner membrane structures are found. In amyotrophic lateral sclerosis ( ALS), Alzheimer's disease and Parkinson's disease , for example, cristae morphology is disrupted by mitochondrial inclusions as well as abnormal configurations of the inner membrane
