Title: Organization of Living Things


1
Organization of Living Things
2
Atom Makes up all living and nonliving things
3
Cell Basic unit of living things - 210 cell types
nerve cell
hair cell
muscle cell
stomach cell
blood cell
Muscle cell
4
Tissue Many cells performing a function - blood,
muscle, bone
5
Organ Several tissues working together - heart,
root, liver, leaves
6
Organ System Several organs working together
circulatory system, digestive system, etc.
7
Individual Organ systems working
together! Snakes, maple tree, grasshopper
8
Population A group of individuals (school of fish)
9
Community All living things in an area
10
Ecosystem All living and non-living things in an
area Prairie - grasses, hawk, snake, soil, etc.
11
Planet
12
Cell Basics
Theories on formation Types of cells
Differences in cells
13
Cell Formation- Which Theory?
  • Spontaneous Generation- the thought that living
    things can appear from nowhere- not true

14
Cell Theory
  • All living things are made of cells
  • All cells come from other cells
  • Cells are the most basic unit of LIFE

15
All Cells Four Major Parts
  • Cytoplasm
  • Cell Membrane
  • Genetic Material (DNA)
  • Ribosomes

animal cell
bacteria
16
Two Types of Cells
  • Prokaryotic simple cells with no nucleus
  • (bacteria and archae)

pro before karyo nucleus
17
Two Types of Cells
B) Eukaryotic Larger cells with more
organelles and a nucleus (plants, animals, fungus
and protists)
eu true karyo nucleus
18
Two Types of Eukaryotic Cells
  • Plant Cells have a cell wall, central vacuole
    and chloroplasts

19
Two Types of Eukaryotic cells
Animals Cells have no cell wall or chloroplasts
20
Differences in cells
Cells can be different sizes- bacteria v
egg Cells can be different shapes- blood cell
versus muscle cell
