Crusts and uppermost mantle
Answer:
The correct answer is - they both have highly folded membranes.
Explanation:
Organelles such as the endoplasmic reticulum, Golgi apparatus, and mitochondria have highly folded double membranes. This highly folded membrane provides the increased surface area in the organelle.
As the inner membrane of these organelles is the site for many chemical reactions the highly folded or layered membranes get more space for such reactions to occur due to increased surface area.
I don't think they are.
Vascular bundles are strands of tissues, which function as transport system in plants. So they are a kind of tissues, not organs.
Ribosomes are the protein builders or the protein synthesizers of the cell.
