Question

what characteristic is shared by both mitochondria and chloroplasts? multiple choice circular dna and double membranes thylakoids and grana matrix and cristae can live independent from cells

Explanation:

• Analyze each option:
• Option 1: Mitochondria and chloroplasts both have circular DNA (similar to prokaryotic DNA) and are surrounded by double membranes (supporting endosymbiotic theory).
• Option 2: Thylakoids and grana are unique to chloroplasts, not mitochondria.
• Option 3: Matrix and cristae are structures of mitochondria, not chloroplasts.
• Option 4: Mitochondria and chloroplasts cannot live independently from cells as they are organelles dependent on the host cell's environment.

Answer:

A. circular DNA and double membranes
