Cell Structure 1
Cell Theory
1. Living things are made of cells.
2. Cell are the basic unit of structure and function.
3. New cells come from existing cells
Prokaryotic Cell
-Bacteria
-Do not have a nucleus (have DNA)
-Some have flagella
-Pili attach to surfaces
-Divide to reproduce
Smooth ER
Lipid synthesis
Ribosomes
Makes Protein
Cytoplasm
Liquid interior
Cell Differentiation
Cells within your body vary in size, structure, and function.
ATP
Useable form of energy
Nucleus
Directs cell activities
Contains genetic information (DNA) in the form of chromatin
Organelles
Little organs
Performs specific functions
Nucleolus
Responsible for the production of ribosomes
Cellular respiration
Chemical energy from food is converted to a usable form (ATP)
Eukaryotic Cell
Cells that have a membrane-bound nucleus with chromosomes
Endoplasmic Reticulum
Transport system; canals and channels that connect membrane to nucleus and to organelles within the cell
Rough ER
Has ribosomes on the surface
Ribosomes make protein
Lysosomes
contain enzymes to break down substances
Vacuole
Storage area
Golgi Apparatus
Package and delivery of proteins produced by the ribosomes
"Post office of the cell"
Mitochondria
Powerhouse of the cell
Enzymes
Break down substances in the cell, such as food or worn out cell parts, even bacteria.
Chromosomes
Thread-like structures found within the nucleus of cells that carry genetic information.
