schleiden  invention about cell in explainig structure and also mention the work

Answer 1

All of their combined work. Schleiden: Announced that all plants are composed of cells1. Schwann: Discovered that all animals are made up of cells1. Virchow: Discovered that cells only come from other cells1. His statement was later debunked. Cells1 : Definitionnoun (Science: Cell Biology) 1. The structural, functional and biological unit of all organisms. 2. An autonomous self-replicating unit that may exist as functional independent unit of life (as in the case of unicellular organism), or as sub-unit in a multicellular organism (such as in plants and animals) that is specialized into carrying out particular functions towards the cause of the organism as a whole. 3. A membrane bound structure containing biomolecules, such as nucleic acids, proteins, and polysaccharides. Supplement There are two distinct types of cells: prokaryotic cells (e.g. bacterial cells) and eukaryotic cells (e.g. plant or animal cell). The main difference between the two is a well-defined nucleus surrounded by a membranous nuclear envelope present only in eukaryotic cells. Despite this difference they share a number of common features: the genetic information is stored in genes, proteins serve as their main structural material, ribosomes are used to synthesize proteins, adenosine triphosphate is the main source of metabolic energy to sustain various cellular processes, and a cell membrane that controls the flow of substances into and out of the cell. Word origin: From Latin cella. Related forms: cellular (adjective)
