What is found only in plant and algae cells that consist of two envelope like membranes that surround a folded inner membrane?
Chloroplast
In most animal cells what are two things found surrounded by a membrane?
The nucleus and mitochondria both have membranes, as does the entire cell.
Name two parts in animal and plant cells that are the same?
cell membranes, chlorophyll, nucleus, nuclear membrane - that's all the ones I can remember
What are two activities that are characteristic of cell but not of viruses?
Cells can reproduce without help, cells can not invade other cells, cells have cell membranes and cells have a nucleus
Are both chloroplasts and mitochondria bounded by two membranes?
Yes. The outer membrane is similar to modern eukaryotic membranes, such as the plasma membranes of animals and plants. The inner membrane is similar to modern prokaryotic membranes, found in bacteria. This difference has been taken as one piece of evidence to support the theory of the endosymbiotic origin of these two organelles, i.e. the idea that each of these organelles formed originally from the engulfing of a prokaryotic cell by a eukaryotic one.
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.
In eukaryotic cells the cell organelle that is surrounded by two membranes?
mitochondria, nucleus, chloroplast
What did a nucleus do?
the nucleus has the cells DNA and is covered by two membranes. The DNA contains the info to make proteins and the nucleus powers the whole cell. -alex s(:
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
What is found only in plant and algae cells that consist of two envelope like membranes that surround a folded inner membrane?
Chloroplast
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.
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.
In most animal cells what are two things found surrounded by a membrane?
The nucleus and mitochondria both have membranes, as does the entire cell.
Is a cell membrane a prokaryotic cell or a eukaryotic cell?
Both prokaryotes and eukaryotes have cell membranes. The main difference between the two is that eukaryotic genetic material is bound in a nucleus, while prokaryotes do not have a nucleus.
Name two parts in animal and plant cells that are the same?
cell membranes, chlorophyll, nucleus, nuclear membrane - that's all the ones I can remember
What are two activities that are characteristic of cell but not of viruses?
Cells can reproduce without help, cells can not invade other cells, cells have cell membranes and cells have a nucleus
What is the description of a nuclear membrane?
I have a PHD in science and i would like to tell the descripition of Nuclear Membrane. Nuclear Memrane- Two membranes that surrounds the nucleus. Have an awesome day!
