Transcript of Cell Organelles

The Search for how it all works together.
Cell Organelles
Nucleus
tiny cell structures that carry out the specific functions of the cell.
Organelles:
transports materials (proteins) around the cell.
Endoplasmic Reticulum (ER)
Vacuole
stores mostly water.
Mitochondria
controls all cell activities.
Functions:
Produce ENERGY
BUILD/TRANSPORT materials
STORE/RECYCLE food/waste
Boundary separating cell from the environment.
Cell Membrane:
Semi-permeable:
Lets some things through, but not everything.
Prokaryotic cells have chromatin, just not contained in the nucleus.
Nuclear Membrane:
Chromatin:
Nucleolus
surrounds the nucleus to protect it.
genetic material, gives instructions to the cell for everything.
produces ribosomes.
holds all of the organelles in place, gives shape and structure to the cell.
Cytoplasm:
Gel-like substance.
provides energy for the cell, and all living things.
Respiration: process of turning glucose to ATP.
Rough: covered with ribosomes.

Smooth: no ribosomes.
transports materials (proteins) around the cell.
Endoplasmic Reticulum (ER)
Rough: covered with ribosomes.

Smooth: no ribomsomes.
more common in plant cells, takes up the extra space.
Lysosome
recycles old cell parts to be reused in the cell.
more common in animal cells.
Cell Wall
gives the cell lots of extra strength, like an exoskeleton.
Made of crunchy cellulose (non-living) material.
Chloroplast:
capture energy from the sun to make food.
Chlorophyll: green "dye" to capture the energy from the sun.
produces protein to produce other parts of the cell.
Ribosome:
Protein Synthesis: process of making proteins from RNA.
packages materials to be distributed throughout the cell.
Golgi Body (Apparatus):
Flattened sacks/tubes running through the cell, often near the nucleus.
