Which organelle is surrounded by two membranes?
Nucleus and Mitochondria. all the orgenelles are: vacuole, nucleus, nucleolus, Golgi body, endoplasmic reticulum, ribosome, chromatin, nuclear envelope, cell membrane, mitochondria, cytoplasm,and lysosomes for an animal cell, What you mean by surrounded by 2 membranes idk
How many membrane layers cover the nucleus?
There isn't a specific number of membranes that a eukaryote has, mainly because it is unknown how many organelles are in a cell and how many cells are in an organism. A eukaryotic cell is surrounded by one plasma membrane, but most organelles within the membrane are also covered with membranes, sometimes two in case of mitochondria or chloroplast.
Plastids that are surrounded by more than two membranes are evidence of?
Plastids that are surrounded by more than two membranes are evidence of endosymbiosis, specifically secondary endosymbiosis. This process involves the engulfment of one photosynthetic eukaryote by another, leading to the presence of multiple membrane layers around the plastid.
Why does the mitochondria have two membranes?
The mitochondria has two membranes because it is believed to have originated from a symbiotic relationship between an ancient cell and a bacteria. The outer membrane helps protect the organelle, while the inner membrane is where important processes like energy production occur.
Is the following sentence true or false Both chloroplasts and mitochondria are enclosed by two envelope membranes?
True. Both chloroplasts and mitochondria have a double-membrane envelope that surrounds their organelle structures.
In eukaryotic cells the cell organelle that is surrounded by two membranes?
mitochondria, nucleus, chloroplast
In eukaryotic cells the cell organelle that is surrounded be two membranes and that is the site of cellular respiration which produces ATP?
Mitochondria

What are mitochondria surrounded by?
Mitochondria are surrounded by membranes.They have two membranes.
What is is the nucleus surrounded by?
The nucleus is surrounded by two types of cell membranes, the inner and outer nuclear membranes. The nucleus can also float around in the cytoplasm.
Does mitochondria contain a membrane?
Mitochondria are surrounded by membrane.Mitochondria have two membranes.
What is surrounded by two membranes Contains a matrix called stroma which has a system of membranes running through it these are stacked in places to form grana containing chlorophl stroma contai?
This description matches the structure of a chloroplast, a cell organelle found in plant cells responsible for photosynthesis. Chloroplasts are surrounded by two membranes and contain a matrix known as stroma, within which a system of membranes called thylakoids are present. Thylakoids are stacked in some areas to form grana, which contain chlorophyll, the pigment involved in capturing light energy for photosynthesis.
How may cell membranes does a double membrane organelle have?
The cell membrane is a lipid bilayer while the organelle membranes are usually a single layer of lipids. The nucleus, mitochondria and chloroplasts are the exception and have a lipid bilayer. AS you see, it depends on which organelle. The nucleus, mitochondria and chloroplasts have a bilayer (2). The others have one.
What is a cell organelle with two membranes and is the main power source of a cell?
That would be mitochondria.
What is the fluid portion of chloroplast?
It is in the mid region.It is surrounded by two membranes.
Endosymbiotic theory explains the formation of organelles surrounded by how many membranes?
Endosymbiotic theory explains the formation of organelles surrounded by two membranes. This theory suggests that eukaryotic organelles such as mitochondria and chloroplasts originated from symbiotic prokaryotic cells that were engulfed by a host cell, leading to a mutually beneficial relationship.
How many membrane layers cover the nucleus?
There isn't a specific number of membranes that a eukaryote has, mainly because it is unknown how many organelles are in a cell and how many cells are in an organism. A eukaryotic cell is surrounded by one plasma membrane, but most organelles within the membrane are also covered with membranes, sometimes two in case of mitochondria or chloroplast.
