NEET BIOLOGY

Detailed explanation-1: -mitochondrion, membrane-bound organelle found in the cytoplasm of almost all eukaryotic cells (cells with clearly defined nuclei), the primary function of which is to generate large quantities of energy in the form of adenosine triphosphate (ATP).

Detailed explanation-2: -Furthermore, it is no surprise that mitochondria are present in both plants and animals, implying major commonalities in regulation, energy production, substrates employed, etc. This common presence of mitochondria, with similar functions and structure, underscores how close our life forms are.

Detailed explanation-3: -The plant cell has a cell wall, chloroplasts, plastids, and a central vacuole-structures not found in animal cells. Plant cells do not have lysosomes or centrosomes.

Detailed explanation-4: -Plant cells typically contain several hundred physically discrete mitochondria. For example, Arabidopsis mesophyll cells contain 200–300 discrete mitochondria, while tobacco mesophyll protoplasts contain 500–600 (Logan, 2010; Preuten et al., 2010).
