Multicellular
Organisms made of many cells
Prokaryote
PRO-NO
Simple cell, no membrane, bounded organelles
Eukaryotic
EU-DO
Contain membrane, bound organelles, nucleus
Mitochondria
Used in respiration, uses up sugars, powers plant
Ribosomes
Make protein
Gytoplasm/skeleton
Gives cell structure, pathway for transport vesicles
Membrane
Selectively permeable, molecules in and out via different methods
Nucleus
“Headquarters”
Gives instructions to make protein, contains DNA
Endoplasmic Reticulum
- Rough has ribosomes on surface, used to transport proteins
- Smooth makes lipids, used in detox
Golgi
Sorts things, receives, packages materials to send to cell, membrane
Glucose travels via
Protein to get into the cells
Facilitated and simple diffusion both require
No energy and both transport molecules along a “concentration gradient”
Difference between facilitated and simple diffusion
Facilitated uses protein, simple requires no proteins
Endocytosis is the process of
Molecules moving into the cell
