Anatomy-unit 3

cell the basic unit of all life forms
Anton Van Leeuwenhoek dutch drapemaker who was the first to use the microscope to observe nature, bacteria, blood cells, and sperm cells
Robert Hooke English sientist who observed cork cells in 1665 and coined the term "cell"
Matthias Scleiden German botanist who concluded that all plants are made of cells in 1838
Theodore Schwann German zoologist who concluded that all animals are made of cells in 1839
Rudolf Virchow German physician who concluded that all cells are created from preexisting cells
Cell theory 1. All living things are composed of cells 2. cells are the basic unit of structure and function in living things 3. new cells are produced from existing cells
cell size a typical cell is from 5 to 50 micrometers
cells and tissues tissues are groups of cells that are similar in structure and function-structure reflects function
anaomy of the generalized cell cells are not all the same, all cells share a general structure, cells are organized in 3 parts 1. nucleus 2. cytoplasm 3. plasma membrane
Prokaryotic cells cells that lack a nucleus and membrane bound organelles, ex. bacteria
eukaryotic cells cells that have a nucleus and membrane bound organelles ex. plants, animals, fungi, protista
The nucleus acts as the control center of the cell that contains genetic material (dna)
Nuclear membrane the barier of the nucleus, which contains nuclear pores, used in the exchange of materials with the rest of the cell (semipermeable membrane)
nucleolus nucleus contains one of more nucleoli, site of ribosomal until assembly, and contains DNA and RNA
chromatin composed of DNA and protein, scattered throughout the nucleus (when cell divides chromatin condenses to form chromosomes when the cell divides
chromosomes DNA and Protein in a coiled rod shaped form during cell division
plasma membrane double phospholipid layer (fat and water) with two separate ends. One is hydorphobic, water fearing, and the other is hydropholic, water loving
cell membrane functions 1. sepatation of cytoplasm from extracellular fluid 2. regulates exchange of materials 3. structural support 4. sensitivity to changes in the concentrations of carious fluids
proteins in the cell membrane 1. regulate ion passageways 2. act as carrier molecules 3. bind to ligands
