What is the basic unit of all life? Cells All cells must share the features that enable them to what? Perform the functions necessary for life. Robert Hooke Discovered the calls while looking at cork under his microscope. Antoni van Leeuwenhoek First to describe living cells Larger Cells Need more proteins (energy cost) Smaller Cells Can absorb more because their is more surface area to volume Can maintain small size, within itself Two Tenets of the Cell theory 1. All living organi...

Light Microscope - -visible light is passed through a specimen Magnification - -ratio of image to real size Resolution - -image clarity Contrast - -difference in brightness Cell fractionation - -Takes cells apart -separate organelle -Determine function of organelles Prokaryotic Cell - -NO nucleus -DNA is unbound region (nucleoid) Eukaryotic cells - -DNA is in nucleus -membrane bound organelles -larger then prokaryotic cells The Nucleus - -Cell's genes -DNA in chromosomes Nucleolus...

Eukaryote : An organism whose cells contain complex structures enclosed within membranes. The defining membrane bound structure thats sets them apart from prokaryotic cells is the nucleas or nuclear envelope within which the genetic material is carried. All species of large complex species are eukaryotes, including animals, plants and funghi. Euchromatin : This shows as pale areas in the nucleas under electro magnification. It is a less densly packed form of chromatin; 10% is even l...
