Unit 2 Concept 1 - Cell Theory and Organelles Flashcards
cell theory
all living things are made of cells
cells are the basic unit of life
all cells come from other cells
unicellular
composed of one cell
multicellular
composed of many cells that may organize into tissues, organs, and organ systems
prokaryotic
no nucleus
no membrane-bound organelles
binary fission division
unicellular
cell walls
bacteria
eukaryotic
nucleus
membrane-bound organelles
mitosis division
uni/multicellular
only fungi and plants
animals, plants, fungi, protists
all cells have…
genetic material

organelles
Subcellular structure that has 1 or more specific jobs to perform in the cell
phospholipid bilayer
proteins, carbohydrates, fluid mosaic model, hydrophilic head, hydrophobic tail
