prokaryote & eukaryote

• The cell membrane is a semi-permeable outer covering of cells that controls the entrance and exit of materials in the cell.
• nucleus - genetic material, control the cell
• cell menbrane - control substance in or out, semi-permeable
• mitochondria - release energy locked up in glucose by aerobic respiration
• cytoplasm - location of chemical reaction, contains dissolved nutrients, salt and organelles
• ribosome - synthesis protein, tiny structure
• animal cell size - 10-30μm
• eukaryotic cells have cytoplasm, cell membrane, genetic material in nucleus, and they are multicellular
• cell wall - (made of cellulose fibers) provide structural strength and support
• vacuole - (filled with cell sap) could expand or shrink. keep the cell turgid
• chloroplast - (contain chlorophyll) absorb light energy to make glucose(photosynthesis)
• animal cell size - 10-100μm
• prokaryotic cells have cytoplasm and cell menbrane surrounded by a cell wall, and they are unicellular
• mitochondria is too big to fit in prokaryotic cells
• bacteria use binary fission to reproduce
• prokaryotic cells don't have genetic material in nucleus
• loop of genetic material - DNA aren't linear, circular loop with no begin or end, flow freely
• plasmid - small loops of genetic material, could be passed easily
• flagellum - swim in water
• slime capsule - prevent the bacteria from drying out (if in air)
• bacteria cell size - 1μm
• eukaryotes are more complex than prokaryotes
