Where science begins
needs of life
all organisms need nutrients
this provides them with everything they need to survive
senses
hearing: sound travels in waves outward in all directions from the source
taste: smell and taste work together to heighten your sense of taste
eye: your eyes are desighned to focus light rays in a way to form an image
smell: odors or smells are chemicals that are carried through the air
viruses
proof they are living
they are able reproduce but only in a host cell
contain genetic material
proof they are not living
not made of cells
they cant move on their own
Classified
1 type of host(organism that provides
shelter and nutrients)
2 Shape each type of virus has aspecific shape
bones
our skeleton give our body the shape that we have
bones are made of compact and spongy bone
all bones are made of living bone cells
surronded by nonliving material
exoskeleton: organism's support structure is found on the outside of it's body
cells
organelle:(small organ)
small parts of the cell
found floating in the
cytoplasm
cell theory was developed from the research of many scientists
there are more than one type of microscope
simple microscope
compound microscope
TEM
plant cell has a cell wall
animal cell only has cell membrane
muscles
diffrent types
skeletal: moves bones
cardiac:pumps blood
smooth:makes uo internal organs
living or not
viruses are very small and everywhere
all living things respond to their surrondings
all living things are made of cells
Metabolism process
1 break down food in stomach
2 change food into energy
3 body transports energy where its needed
4 waste is removed from body
Within each muscle are nerves and blood vessels
