Cell Flashcards
Learn definitions for cellss (21 cards)
Unicellular
Organisms made of one cell
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
Exocytosis is the process of
Molecules moving out of the cell
The cell membrane is made out of
Proteins, phospholipid bilayer
Explain phospholipid bilayer
Bilayer means two layers with heads polar (attracted to water) and tails non polar (water hated)
Heads are phosphate, hydrophilic
Tails are fattyacid lipid, hydrophobic
What method of transport to oxygen and carbon dioxide cross membrane using?
Genetic material, cytoplasm, ribosomes
Proteins
Surface proteins used for messages
Transmembrane protein is the transport
Does all oxygen and carbon dioxide have to go through the membrane
Yes
Polar means
Energy charged
