CELLS!

So basically science isn't my best subject! But, the one thing I do enjoy learning about is cells. (thanks to Robert Hooke -- the man who discovered them!) (: Don't ask why, because i'm not sure! ha but here is some information that i gathered...

Bacteria is single celled.. but certain things like animals (us) are multicellular.. we have about 100 trillion cells!

Most cells are not visible to the unaided eye because, they are so tiny. In fact, one of the only visible cells to the unaided eye is the human egg.. BUT cells are pretty important in all living things. They are so small that even under a microscope they seem tiny. You may be able to see things like the nucleus with the help of a microscope. In other words, cells are pretttttty small! This is one place size doesn't matter, cells carry out a number of tasks.

There are two different types of cells: plants & animals. The main difference between the two is a cell wall, which a plant has and the animal doesn't. This shapes and supports the cell.

Here's what each cell does have:

Cell membrane: think of this as "skin" it let's things in and out.

Chlorophyll: (in plants) this traps light and is used to produce food.. yummy.

Chlororplasts: (again in plants) think of this as the kitchen! food is made here..

Chromosomes: think of this as the computer (: these contain codes that guide cell activites..

Cytoplasm: it's just a jellylike substance

Endoplasmic reticulum: surface for chemical activity

Golgi bodies: these little things store & release chemicals

Lyosome: think of this as the tummy! it's the digestive center

Mircotubule: hollow cylinder that supports and shapes cell

Mitochondria: the powerhouse!

Nuclear membrane: holds the nucleus together!

Necleolus: body inside the nucleus

Nucleus: where the chromosomes live!

Plastid: stores food. -fridge (:

Ribosomes: another kitchen! proteins are made.

Vacuole: this contains water & dissolved minerals

I know it's not easy to remember.. so here's a picture of an animal cell

and.. a plant cell:

Cells are the center of living things. Without them, we wouldn't exsist. There are plenty more details that I could explain about cells, so know these are just the basics. (:

Here's a YOUTUBE video on cells (:
