Living Midterm
All living things are made of..
Cells
Single Celled
Unicellular
ex. bacteria
Multiple cells
multicellular
ex. humans
Prokaryotic
no organzied nucleus, no membrane bound organelles, found in bacteria
eukaryotic
organized nucleus, membrane organelles such as chloroplasts and mitochondria
DNA
genetic code is the SAME for ALL living things on earth
Development
cells grow and divide into specialization in cells
metabolism
combination of chemical reactions through which an organism builds up or breaks down materials it carries out life processes is called metabolism.
Autotrops
energy from sun (plants, most algae, some bacteria)
heterotrophs
rely on energy stored through photosynthesis
HOMEOSTASIS
maintaining a stable internal enviornment
level of organization
organelle, cell, tissue, organ, organ system, organism
Cell theory
-All living things are made of cells
-cells are the basic unit of all life on earth
-all cells come from pre-existing cells
ONLY plants cells have
large central vacoule, cell wall, chloroplasts
organelles work together to carry out
diffusion
lysosomes
organelles that break down old parts of the cell
carbohydrates
-An organic compound that is a key source of energy
-bulding blocks are monosachirides like glucoss
Dissachirides
double sugar
polyssacchirides
thousans of sugars linked together
oragnic
contains hydrogen and carbon
glucose
C6H12O6
