Cells are living units that move, grow, react, protect themselves, and reproduce.
Human Cells • blood cells • muscle cells • nerve cells • bone cells • skin cells
Cells have a round core called the nucleus. The nucleus is the “brain” of the cell.
It tells the cell how to reproduce and what function each part of the cell is responsible for performing.
nuclear membrane thin coating that covers the nucleus . It is covered with small holes called nuclear pores.
These pores allow material to be passed back and forth between the nucleus and the rest of the cell.
NUCLEAR MEMBRANE NUCLEAR PORES
cytoplasm gel-like substance that floats between nuclear membrane and the thin outer shell of the cell called the cell membrane.
Cytoplasm supports the shape of the cell and keeps floating pieces in place.
It also has chemicals and protein particles in it that help keep the cell alive.
cell membrane helps keep shape of the cell and controls entry of oxygen into the cell and waste products out of the cell.
mitochondria powerhouse of the cell that stores energy like a battery until it is needed by the cell
Its function is to break food particles down into energy and then store this energythe cell will need to reproduce and survive.
Golgi bodies stacks of flat sacks
Golgi bodies store protein and transport it and chemicals to other parts of the cell.
nucleolus small sphere inside the nucleus that manufactures ribosomes
ribosomes small,round shapes that make protein
endoplasmic reticulum hollow sheets of thin material where ribosomes are attached
vacuoles round bubble-like structures that contain water and dissolved minerals
Vacuoles are fairly small in animal cells. Plant cells contain huge vacuoles.
lysosome • digestion center of the cell • digests particles that may be harmful to the cell
microtubules hollow cylinders that help shape and support cell
centrioles help with cell reproduction
