Question

question match the organelle with its characteristics: mitochondrion. answer composed of two subunits; can be free in the cytosol or attached to rough er produces protein transport vesicles possesses a cis and trans side; composed of cisternae cristae; matrix composed of microtubules arranged in nine groups of three i dont know yet 86% 25 total questions

Explanation:

To solve this, we analyze each option:

• "Composed of two subunits; can be 'free' in the cytosol or attached to rough ER" describes ribosomes, not mitochondria.
• "Produces protein transport vesicles" is a function of the rough endoplasmic reticulum (ER), not mitochondria.
• "Possesses a cis and trans side; composed of cisternae" describes the Golgi apparatus, not mitochondria.
• "Cristae; matrix" – Mitochondria have a double - membrane structure. The inner membrane is folded into cristae, and the space enclosed by the inner membrane is the matrix. This is a characteristic feature of mitochondria.
• "Composed of microtubules arranged in nine groups of three" describes centrioles, not mitochondria.

Answer:

The option "Cristae; matrix" (the fourth option in the list)
