Environment

Energy

Cell
The smallest unit of a living organism and the basic building block of life
Cell theory
A theory stating that all living things are made of cells and that the cell is the the smallest form of life and cells come from old cells
Nucleus
The largest organelle in the cells control center
Nucleus a
Contains DNA (genetic material) to give directions to make proteins for repair making new cells or parts
Nucleus b
The nucleus has its own membrane around
nuclear pore
protien in the nuclear membrane which allows certain things to enter the nucleus
chromosones
tiny bondule of DNA in nucleus
mitochondria
responisble for producing and realising energy for the cell use
another word for food is sugar, gluclose fruitose and luctose.
endoplasmic recticulum
system of passage ways that allows materials to transport from one part to of the cell to another.
endoplasmic recticulum(ER)
there are 2 typesof er rough and smooth
charatestics of life
living things are made of cells grow and develop reprouduce after thier own kind respond to stimulus in enviroment use energy
E and R
There are two types of ER rough and smooth
Rough er
Has an organelle called ribosomes attached to it
Smooth er
Has no ribosomes
Rough er a
Will be found attached to nucleus
Ribosomes
Produce protein for cells
Vacuole
Storage center for food, water, and waste in a cell until it can be used or released by the cell
Lysosome
Structure in a cell it helps to digest and recycle old cell parts and food contains digestive enzymes like stomach.
