From the Cell to an Organism AMOC-TOOOP-CEBB
Title Date U3-10
Cells • What is the smallest unit of life? Cell Types Prokaryotes Eukaryotes bacteria Animal Plant
Cell Types • Organelles are cell parts that do specific jobs. • Prokaryotes have no nucleus. • What organelles do plant cells have that animal cells do not? Ven Diagram
Cell Types Ven Diagram Plant Cell Animal Cell
Cell Types • All cells have a phospholipid cell membrane. • All cells have DNA. Eukaryotic cells have DNA in a nucleus. • Cytoplasm is a jelly like material that makes up the inside of the cell.
Basic Cell Parts Cell Membrane Cytoplasm DNA Nucleus
Organelles • What are cell parts called? • There are 3 important cell systems. • Endomembrane System • Cell Boundaries • Energy Production • The Production Factory • Cell Skins • The Power Factories
Organelles • 1. Production Factory. • What do you think cells produce?
The Production Factory • From DNA to Protein • Nucleus Ribosome Protein • Let’s break it down.
From DNA to Protein • The Nucleus is where the DNA is stored. • Messenger RNA is made from the DNA. • It leaves the nucleus from a pore.
From DNA to Protein • Ribosomes make protein from mRNA.
Organelles • 2. Power Factories. • Why do cells need energy?
Cell Energy Production Cells Need Energy to do Work. What kind of energy do cells use? Hint: Think molecules. ATP
Cell Energy Production • The mitochondria is an organelle that makes ATP from glucose. Like a little battery! – +
Cell Energy Production All glucose comes from a process called… photosynthesis
Cell Energy Production • The chloroplast is the organelle that performs photosynthesis to make glucose. • Some glucose is stored as starch and some is used by the mitochondria to make ATP.
Material Storage • Vacuoles are storage organelles • Plant cells have a giant central vacuole for storage and cell support.
Organelles • 3. Cell Skin. • For eating, protection, and support.
Cell Boundaries • The skin of a cell and the sacs that make up organelles are made of which lipid? • Phospholipids. • The Cell Membrane is the outer skin of all cells. • It is a semi - permeable barrier that lets certain things in and out of the cell.
Cell Boundaries • Cell Membranes are lipid bilayers. • How are phospholipids different than other lipids? hydrophilic hydrophobic hydrophilic
Cell Boundaries • The cell membrane has many membrane proteins stuck in it. • Receptors – flags or tags • Gates – allow things in or out • Enzymes – do reactions
Cell Boundaries • A cell wall provides support and protection to a cell, it is placed over the cell membrane. • Plant Cells • Cellulose
