Transcript Cell structure and function

Cell Structure and Function
• The icons on the slides are designed to
help you remember the function of each
cell part.
Cell Membrane
•A continuous, almost invisible
structure surrounding the cell
•controls what enters and leaves
Cytoplasm
•The cell’s jelly-like environment
•Made mostly of water
•Contains salts, dissolved gasses,
and wastes
Nucleus
•The cell’s control center or brain
•Uses DNA to control all cell activities
•Contains chromosomes
Ribosomes
•Creates the product of the cell –
proteins that will become body
structures
Endoplasmic Reticulum (E.R.)
•The cell’s transportation system
•Allows a place for cell reactions
•Ribosomes are attached to it.
Golgi Bodies
•Packs and carries proteins in little
bubbles that separate and float
into the cytoplasm.
Mitochondria
•The cell’s powerhouse
•Breaks down food and releases
energy that the cells need
•Location of aerobic respiration
Lysosomes
•The cell’s recyclers
•Contain powerful digestive enzymes
•Break down worn out product to be used
again
