50x, 200x, 500x.
what are the 6 main organelles?
nucleus, vacuoles, cell membrane, cytoplasm, chloroplast, cell wall.
what is the function of the organelles?
nucleus-brain, vacuoles-holds extra water, cell membrane-goes around contents, cytoplasm-jelly like environment, chloroplast-makes food, cell wall- stops the cell from bursting.
what organelles are only in plants?
cell wall, chloroplast.
what is diffusion?
the movement of minerals from the inside of a cell to the outside.
what makes it so a cell can pick what goes in and out?
a selectively permeable.
what types of things would a cell want in?
O2, nutrients.
what types of things would a cell want out?
waste, CO2.
what are atoms?
smallest thing.
what are molecules?
single celled organisms.
what are cells?
the smallest living things.
what are tissues?
made of cells/keeps us together.
what are organs?
made of tissues/make us live.
what are organ systems?
made of organs/make us work.
what is the circulatory system?
the system that pumps our blood.
what are the parts of a heart?
right atrium, right ventricle, left atrium, left ventricle.
What is the job of the atrium?
