Bacteria are different from all other living things because they lack what?
They lack membrane enclosed organelles
Why is the plasma membrane selectively permeable?
The plasma membrane is selectively permeable because it needs to allow certain things in and certain things out.The plasma membrane is a selectively permeable membrane as it allows the entry and exit of some selected substances only.
What is a list of things that might go wrong in the cell without the cell membrane's help?
the bacteria and virus can easily enter into the cell.this make the cell to damage
Can humans live without monera why?
No, because they are a type of bacteria. Even though bacteria can be bad there is also some good bacteria as well. We need the good bacteria for medicine like penicillin and other things
Why has bacteria only one chromosome but amoeba has several?
Because amoebas are more advanced in their design then bacteria, therefore they need the chromosomes to encode that information. Examples are like how amoebas have membrane bound nucleus and many organelles, in contrast bacteria lack these things. Also amoebas are much larger in size. However amoebas have many very small chromosomes, while bacteria have one larger one. So the amount of information on each chromosome is also in large contast
Bacteria are different from all other living things because they lack what?
They lack membrane enclosed organelles
Is the function of the cell membrane in all cells producing neutrients?
No. The cell membrane does not produce nutrients. The cell membrane contains the cell and lets in certain things (Selectively Permeable) while denying bacteria and dangerous things access. It also retains moisture.
What are the bad things that are not allowed into a cell?
In an animal cell, the plasma membrane keeps out unwanted objects. In a plant cell, the cell wall does this. Unwanted items would be any foreign unknown object, harmful bacteria, or wastes excreted by other cells. Cells only let in certain things, and they do this through selective permeability. They let in water and sugars and nutrients and other things that the cell requires. They can tell what to let in because proteins attached to the plasma membrane act as signalling devices, telling the plasma membrane whether or not to let something in. Some bacteria trick the plasma membrane into letting them in.
Is bacteria a organelle?
No it's not, it is a prokaryote and contains no membrane bound organelles. Organelles are things like mitochondria and endoplasmic reticulum
What does a selectively permeable membrane have to do with osmosis?
nothing because the membrane is to keep out some things and let other things in nothing to do with osmosis at all
What do all the plant cells animal cells and bacteria cells have the same?
they both have a nucleus a cell membrane and cytoplasm
Why is the plasma membrane selectively permeable?
The plasma membrane is selectively permeable because it needs to allow certain things in and certain things out.The plasma membrane is a selectively permeable membrane as it allows the entry and exit of some selected substances only.
How did Pompeii discover things from the past?
It discovered things from the past because those things had happen.
How are things that Louis Pasteur discovered important to people today?
It is important to people today that Louis Pasteur discovered things because if he didnt many people would of died for rabies and other things he discovered......
Why is it important for the cell membrane to be a selectivly premeable?
It is important because, if the cell membrane was not selectivly permable, we would not be able to do the things today.
Where can a semi permeable membrane be found?
The cell membrane, this is because of the lipids that form it. They allow certain things through such as water during osmosis but block other things creating a need for things like protein pumps.
What is a list of things that might go wrong in the cell without the cell membrane's help?
the bacteria and virus can easily enter into the cell.this make the cell to damage
