Cells

• Cellular organisms can be divided into two main groups

  Prokaryote

  Eukaryote
• prokaryotic cell structure

  Pili

  Ribosome

  Cell wall

  Cytoplasm

  Plasmid

  Nucleoid

  Plasma membrane

  Flagellum
• Eukaryotic cell structure (animal)

  Cell membrane

  Mitochondria

  Nucleus

  Cytoplasm

  Ribosome
• Eukaryotic cell structure (plant)

  Cell wall

  Cell membrane

  Vacuole

  Nucleus

  Cytoplasm

  Chloroplast

  Mitochondria
• • mitochondria- site of aerobic respiration, producing the energy needed for cellular functions
• ribosomes- site of protein synthesis
• cell membrane- partially permeable to control movement in and out of the cell
• nucleus- contains genetic information (dna) which controls the cells functions
• cytoplasm - maintains optimum conditions for the cellular organelles
• chloroplasts- contain chlorophyll which is the sight of photosynthesis
• vacuole- contains cell sap, helps maintain cell shape and supports cell structure
