CELL PART STRUCTURE FUNCTION1. Cell (plasma) membrane -bilayer of PHOSPHOLIPIDS - controls what enterswith proteins andor leaves cellcarbohydrates2. Cell Wall - PLANTS only - protects and- made of CELLULOSE supports3. Nucleus - round, surrounded by - BRAIN of cellnuclear membrane- controls all cell(envelope)activitiesa) Nucleolus - round , inside nucleus - helps produceribosomesb) Chromatin - made up of nucleic acids - genetic material(DNA & RNA) - contains the- visible called genetic codechromosomes- info to make all- 2N=46 (human) cell proteinsc) Nucleoplasm - aqueous solution - life functionsORGANELLES4. Mitochondria - ROD shaped - BATTERY- inner folds: CRISTAE - produces ENERGY- fluid: MATRIX - site of CR ( cellularrespiration)5. Ribosomes - 30 nm in diameter - produce proteins- free-floating or on ER (protein synthesis)- free – INSIDE- on ER – OUT6. Golgi Apparatus - stack of flattened balloons - changes fats and- membranes proteins made at ER- PACKAGES themin VESICLES
