Chapter 4 - Cell Structure and Function Flashcards
Cell Theory
All living things are made of cells; cells are basic unit of life; cells come from pre-existing cells
Cell Energy
Comes from sun; cells build and burn energy; split when they get too big
Plasma Membrane
Separates outside from inside; gatekeeper of materials; communications with other cells; phospholipid bilayer
Cytoplasm
The goo surrounding everything in the cell
Enzyme and other protein synthesis
Prokaryotes
Simple and small cells
Cell wall (shape), Capsule (surface attachment), Flagella (movement), Pili (transfer of gametes), Single circular chromosome (DNA), Nucleoid (unbound), Ribosomes (protein synthesis), Mesosomes (respiration)
SCCRiMP FlaN
Cell Wall (Pro and Euk)
Promotes Shape (nearly all have)
Capsule (Pro)
Surface attachment
Flagella (Pro and Euk)
Movement (only some have)
Pili (Pro)
Gamete transfer with other cells
Ribosomes (Pro and Euk)
Protein synthesis (creation)
Mesosomes (Pro)
Cellular Respiration (ATP production)
Eukaryotes
GoVErNuR CiCeLy F MiCy
Golgi, Vesicles, Endoplasmic reticulum, Nucleus, Ribosomes, Cilia, Cell walls, Lysosomes, Flagella, Mitochondria, Cytoskeleton
Plant Cells
Golgi (Euk)
Packages proteins from ER to other destinations
Vesicles (Euk)
Carry waste and other proteins along cell membrane
Endoplasmic Reticulum (Euk)
Produce membrane proteins and new phospholipids
Smooth ER: Steroid productions w/o ribosomes
Rough ER: Long chains of ribosomes for protein production
