Topics include: Cells Discovery, Cells Basic Properties, Cells Classes, Viruses and Viroids. A cell is the basic unit of life, responsible for all life's processes. Cells are the structural, functional, and biological units of all living beings. They can replicate themselves independently, making them the building blocks of life. Here are some functions of cells: Structure and support, Growth, Transport, Energy production, Metabolism, Reproduction. Cells contain genetic material, which is used for long-term information storage. There are two types of genetic material: deoxyribonucleic...

Cells are the structural, functional, and biological units of all living beings. They can replicate themselves independently, making them the building blocks of life. Here are some functions of cells: Structure and support, Growth, Transport, Energy production, Metabolism, Reproduction. Cells contain genetic material, which is used for long-term information storage. There are two types of genetic material: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). In humans, the nuclear genome is divided into 23 pairs of linear DNA molecules called chromosomes. There are two types of cells: prokaryotes and eukaryotes. Eukaryotic cells have a membrane-bound nucleus, numerous membrane-bound organelles, and several, rod-shaped chromosomes. The word eukaryote means “true nucleus”. Viruses and viroids are both infectious agents, but they differ in their composition and structure: Viruses: These small infectious agents are made up of nucleic acids and a protein coat called a capsid. Most plant viruses contain RNA, but some contain DNA. Viruses can't replicate outside of their host and have no independent metabolic function. Viroids: These infectious particles are made up of a single-stranded circular RNA that lacks a protein coat. Viroids produce RNA, while viruses produce proteins. Viroids are carried inside viruses because they lack a protein coat. Show less
