TRANSCRIPT
•The “brain” of the cell
•Large, spherical
•Contains DNA
•Enclosed in a double-layered nuclear membrane
•Ribosome production
•Consists RNA & Protein
•Consists of loose fibers composed of DNA & protein called chromosome
•Contains information for protein synthesis
•Double lipid bilayer
•Protects the nucleus
•Contains nuclear pores
•Passing way between nucleus & cytoplasm
•Allows ribosome to exit nucleus
•Ribosome are found in cytoplasm & ER membrane
•Composed of RNA & protein
•Help in the production of protein
•Made up of a folded membrane
•Provides a tubular transport system inside the cell
Rough ER:
•Has ribosome on surface
•Protein synthesis & transportation
Smooth ER:
•Does not have ribosome on surface
•Lipid synthesis
•Energy source of the cell
•Contain cristae needed for aerobic respiration
•The more folds, the more reactions
•Composed of flattened sacs
•Refines, packages, and delivers the cell products
•Contains powerful enzymes to break up old cell components and bacteria
•“garbage disposals” of the cell
•Contains enzymes that function in the synthesis of bile acids, breakdown of lipids, degradation of rare biochemicals, and detoxification, and detoxification of alcohol.
•Made up of 2 hollow cylinders called centrioles
•Chromosome distribution
•Motile extensions from the cell
•Cilia is shorter than flagella
•Flagella helps sperm cells move
•“jelly stuff” inside the cell membrane
•Selectively permeability
•Signal transduction
•Protects the cell and its organelles within
•Plasma membrane
•Nucleus and nucleolus
•Mitochondria
•Ribosomes
•Endoplasmic reticulum
•Golgi apparatus
•Peroxisomes (the crystal in the electron micrograph is enclosed within a peroxisome)
•Microtubules
• Plant cells differ from animal cells in lacking:
•centrioles
•intermediate filaments
