Fungal Cells & Viruses Mrs. Anderson

How are fungal cells different than plant cells? Fungal cells contain a cell wall that is not made of cellulose, but is made of chitin. Fungal cells may also contain more than one nuclei in a single cell.

Viruses A virus is a non-living particle made up of of a nucleic acid and either a protein or a lipid-protein coat. Viruses cause diseases in living organisms and are useful tools for genetic research.

Virus Structure & Reproduction Extraordinarily small; smaller than prokaryotes (which are typically smaller than euky.) No cytoplasm, no organelles, therefor can not carry out cell functions (like metabolism) They can not grow by dividing.

Virus Structure & Reproduction A virus must enter a living cell and use the host cell’s ribosomes, enzymes, and other molecules in order to reproduce. Are Viruses Alive? Ebola
