Viruses are micro-organisms that lack any kind of membrane. They are acellular and consist mainly of genetic material (either DNA or RNA) surrounded by a protein coat, and they do not possess cellular structures or membranes like living organisms. Viruses rely on host cells for replication and cannot carry out metabolic processes on their own.

What are organisms whose cells lack membrane bound nucleus called?
A prokaryote is a single-celled organism that lacks a membrane-bound nucleus (karyon), mitochondria, or any other membrane-bound organellesIt is the Eukarotes that have membrane-bound organelles.
What cells like bacteria without a nucleus?
Prokaryotic cells lack a true nucleus, and bacteria are prokaryotic cells. They have a nucleoid region where their genetic material is found, but it is not enclosed within a membrane like in eukaryotic cells.
Does ribosome has a membrane?
no they are not surrounded by any membrane
Do prokaryotes lack mitochondria?
No they do not have.They do not have any membrane bound organell.
Do any of the following cells lack a plasma membrane simple squamous epithelium human red blood cells sperm cells teased smooth muscle cells?
Animal cells all have a plasma membrane. Used to just be called the "cell membrane" and separates plants from animals in that plants have a cell wall and animals have the plasma membrane. This is the selectively permeable lipid bi layer found in all cells and is what keeps extracellular material outside the lipid bi layer and keeps the organelles inside the cell.
What are organisms whose cells lack membrane bound nucleus called?
A prokaryote is a single-celled organism that lacks a membrane-bound nucleus (karyon), mitochondria, or any other membrane-bound organellesIt is the Eukarotes that have membrane-bound organelles.
What membrane activities require energy from ATP?
Any kind of active transport.
What makes an organism a microorganism?
Any organism which is too small to be seen with the unaided human eye is by definition a microorganism.
Prokaryotes lack what?
Prokaryotes lack a membrane bound nucleus. This means the nucleus is free to float about the cell. A eukaryote, on the other hand has a membrane bound nucleus.
Is a prey a kind of animal?
Prey is a word used to describe any living thing (plant, animal, or microorganism) that is used as sustenance for another living organism.
What best describes pathogens?
Any microorganism that causes disease.
What is a pathogen best described as?
any microorganism that causes disease.
Which structure does not belong in a prokaryotic cell?
Prokaryotic cells lack any membrane bound organelles such as a nucleus, mitochondria, lysosomes, chloroplasts, golgi apparatus, etc. These membrane bound organelles are only found in eukaryotic cells.
Do Prokaryotes Have Membrane-bound Organelles?
No, prokaryotes do not have membrane-bound organelles. They lack a nucleus and other membrane-bound organelles like mitochondria or endoplasmic reticulum. Instead, their genetic material is located in a region of the cell called the nucleoid.
What structure is found in prokaryotic cell?
Prokaryotic cells lack any membrane bound organelles such as a nucleus, mitochondria, lysosomes, chloroplasts, golgi apparatus, etc. These membrane bound organelles are only found in eukaryotic cells.
What kind of cell has a cell membrane but no cell wall?
any other cell other than plant cells :)
Do micro organisms grow?
Yes, any microorganism in its vegetative state is growing.
