Most cellular organelles have membranes. Mitochondria, chloroplasts and nucleus are special among those because they have double membranes instead of single.
The RER is a rather large organelle and it is next to the nuclear membrane and the cellular membrane.
No, the cell membrane is not an organelle. It is a protective barrier that surrounds the cell and controls what enters and exits the cell. Organelles are membrane-bound structures within cells that have specific functions.
The endoplasmic reticulum is mostly responsible for maintaining homeostasis due to its involvement in protein synthesis, lipid metabolism, and calcium storage and release. The ER helps maintain proper balance within the cell by regulating these processes.
A vesicle is an organelle. It is a small, membrane-bound sac that transports and stores substances within a cell. Vesicles are involved in various cellular processes, such as secretion, transport, and storage of molecules.
Yes, ribosomes are considered a cellular organelle, although they are not bound by a membrane like other organelles such as the nucleus or mitochondria. Ribosomes are responsible for protein synthesis in cells.
The Mitochondria.
Mitochondria possess a double membrane structure because they are believed to have originated from a symbiotic relationship between an ancient prokaryotic cell and a eukaryotic cell. The outer membrane helps protect the organelle, while the inner membrane contains proteins essential for energy production through cellular respiration.
Mitochondria possess two membranes because they are believed to have evolved from a symbiotic relationship between a primitive eukaryotic cell and a prokaryotic cell. The outer membrane helps protect the organelle, while the inner membrane is where important processes like cellular respiration occur.
