CELL ORGANELLE…

Animal Cell

PLANT CELL

CYTOPLASM

Viscous fluid containing organelles

components of cytoplasm

Interconnected filaments & fibers Fluid = cytosolOrganelles (not nucleus) storage substances

ENDOPLASMIC RETICULUM

Helps move substances within cellsNetwork of interconnected membranes

Two types-

Rough endoplasmic reticulumSmooth endoplasmic reticulum

ROUGH ENDOPLASMIC RETICULUM

Ribosomes attached to surfaceManufacture protiensNot all ribosomes attached to rough ER

May modify proteins from ribosomes

SMOOTH ENDOPLASMIC RETICULUM

No attached ribosomesHas enzymes that help build molecules-

CarbohydratesLipids

LYSOSOMES

Contain digestive enzymes Functions- Aid in cell renewalBreak down old cell parts Digests invaders

VACUOLESMembrane bound storage sacsMore common in plants than animals Contents –WaterFoodWastes

MITOCHONDRIAHave their own DNABound by double membraneBreak down fuel molecules (cellular respiration) Glucose Fatty acids

Release energy ATP

central vacuolestorage: food, water or wastemitochondria
