NITTY GRITTY CELL PARTS
CELL THEORY
•All living organisms are composed
of cells. They may be unicellular or
multicellular.
•The cell is the basic unit of life.
•Cells arise from pre-existing cells.
PROKARYOTE VS. EUKARYOTE
ANIMAL CELL
ANIMAL CELL
• Nucleus - the command center of the cell. This houses nearly all the genetic
material of the cell.
• Nucleolus - makes RNA and ribosomes
• Rough ER - transports proteins that were made on the attached ribosomes
• Smooth ER - involved in lipid (fat) production.
• Ribosomes - the factories of the cell. Site of protein synthesis.
• Golgi Apparatus/Body - the post office of the cell. The Golgi receives
proteins from the ER. The packaged proteins are either sent to other parts of
the cell, or sent to the cell membrane for secretion.
• Lysosomes - the cell's recycling plants. Their role is to break down materials.
ANIMAL CELL
• Cell Membrane - the border guard of the cell - this envelope surrounds the
cell and controls which substances can move in and out of the cell.
• Mitochondria - the power station of the cell. Make ATP. ATP is the energy
currency of the cell, used in almost all energy-requiring cellular processes.
• Small Vacuoles – small storage/transport
PLANT CELL
PLANT CELL
• Chloroplasts - Makes Sugar from Sunlight
• Cell Wall - the defensive walls of the plant.
• Vacuole - The large vacuole is filled with water and various solutes.
PLANTS VS. ZOMBIES ANIMALS
OSMOSIS
• Movement of Water across a
semipermeable membrane.
DIFFUSION
• Movement of a solute across a
membrane.
• *Solutes are anything other than
water.
TYPES OF DIFFUSION
• Passive – Doesn’t need energy
• Can pass through membrane no
help
• Facilitated Diffusion – No energy but
needs protein channel.
• Active – Needs Energy
HYPO, HYPER, ISOTONIC
• Hypotonic – Cell more solutes;
solution less solutes
• Isotonic – Equal
• Hypertonic – Cell less solutes;
solution more solutes
