i have no clue what week it is--- SCIENCE HW

this week we started on what an organism was. we had a disscussion in class, and my opinion of a organism was that an organism is a living thing.For example animal, plants, etc. and example of a non-organism is... minerals and water.

this is what i thought since we were talking about potato cells as our example!


an organism is ------> living
a potato is ----------> living
potato cells are in the ----> potato a potato is ----> living ------living means---> organism


Finally we came to a conclusion an organism one or more cells that can independantly sustain life.

after we finished our discusion the next day we learned about prokaryotic and eukaryotic.

a prokaryotic cell is a cell that has no nuclus, a ribosome but no membrane,e. coli and bacteria are examples of prokaryotic.

eukaryotic- is any organiasm that has a nuclus is complex, has membane organelle .
ex. plant cell -> potato
cheek cell -> animal cell


then later we started on working on photosynthesis we did a expirament with why plants need photosynthesis.
we learned about atoms, typles o0f sugers( like glucose and galacose ) we learned about alot of things this week.
