Major events and diversity of cells

Know the people Robert Hooke: named cells “cells” Anton van Leeuwenhoek: living cells, bacteria and protozoa Matthias Schleiden: plants have cells Theodore Schwann: animals have cells Rudolf Virchow: cells come from existing cells Three scientists for cell theory

Cell Diversity: Size (A.) Size is limited by: SURFACE AREA TO VOLUME RATIO As volume (mm 3 ) increases, surface area (mm 2 ) does not increase as quickly. This limits how big the cell can get, making cells remain soooo small Need more explanation??? Click HEREHERE

Light and Electron Microscope Light Microscope Electron Microscope Notice a different between the two microscopes?

Cell Diversity: Shape (B.) Structure (shape) reflects function Nerve Cell: Skin Cell: Blood Cell:

Cell Diversity: Internal Organization (C.) Organelle: component of the cell that has a specific function for cell survival Eukaryote: YOU are a eukaryote (pun is intended) cells that contain a nucleus(all animals and plants) Prokaryote: cells that do not have a nucleus (protists, bacteria)
