The mitochondrial inner membrane is deeply folded.
Mitochondria Plant Cell Characteristics Explained
Let's analyze the statements regarding mitochondria in a plant cell:
-
Statement 1: Mitochondria does not have its own DNA.
This is incorrect. Mitochondria contain their own circular DNA (mtDNA) and ribosomes, allowing them to synthesize some of their own proteins.
-
Statement 2: Mitochondria performs photosynthesis.
This is incorrect. Photosynthesis occurs in chloroplasts, which contain chlorophyll. Mitochondria are primarily involved in cellular respiration.
-
Statement 3: Mitochondria has a single membranous covering.
This is incorrect. Mitochondria are enclosed by two membranes: an outer membrane and an inner membrane.
-
Statement 4: The mitochondrial inner membrane is deeply folded.
This is correct. The inner mitochondrial membrane is highly folded into structures called cristae. These folds significantly increase the surface area for the processes of cellular respiration, specifically ATP synthesis.
Key Takeaway: Mitochondrial Structure
The distinctive feature among the options is the folded nature of the inner mitochondrial membrane (cristae), crucial for its function in energy production within the plant cell.
