What else can I help you with?
Are viruses surrounded by a cell wall?
No, but all cells have a cell membrane. A cell wall is a rigid structure found surrounding the cell membrane. In plant cells, this is made of cellulose, hemicellulose and pectin. Bacteria have a peptidoglycan cell wall. Animal cells do not have a cell wall.
Do all living things have cells?
No, not all living things have cells. While all living things are made up of cells, some organisms like viruses are considered living but do not have cells. Instead, viruses are composed of genetic material (DNA or RNA) enclosed in a protein coat.
Are all organism are made up of one or more cell?
true
What cells do the cell theory apply to?
The cell theory applies to all living cells, including those found in plants, animals, fungi, and single-celled organisms. It states that all living organisms are composed of one or more cells, cells are the basic unit of structure and function in living organisms, and all cells come from pre-existing cells.
Do all cells have cell membranes?
Yes, the cells of archaebacteria, bacteria, protists, fungi, plants and animals all have cell membranes. (Viruses have protein coats, not cell membranes and thus are not true 'cells'.) Thus indeed, all cells possess a cell membrane.
Why do viruses not contradict the idea that all living things are made of cells because?
A virus is an extremely small cell. You can have big cells and little cells. Viruses aren't considered to be alive because they depend on a host cell for energy and reproduction.

Are all the organisms made cell?
yes they are and don't let anyone tell you otherwise
Viruses do not contradict the idea that all living things are made of cells because?
viruses are not considered to be living organisms as they lack the cellular structure and cannot carry out cellular functions on their own. They can only replicate by hijacking the machinery of living cells. Therefore, viruses do not challenge the concept that all living things are made of cells.

true

Are all cell made of other cell?
Cells come from other cells. However they are not made of cells. They are made of organelles and cytoplasm.
Do viruses have liquid cytoplasm?
Viruses are not cells, and therefore have no cytoplasm.
What organism is NOT made up of 1 or more eukaryotic cells?
No.
What type of cells does the cell theory apply to?
every single living organism with cells, so the cell theory, which states what classifies something as a cell, applies to all cells.note: viruses are not alivenote: slime molds such as Physarum polysephalum are acellular.
