Presentation Transcript

  1. Prokaryotes – What are they? • Cells (usually single-celled) with no nucleus • Have no specialized organelles • Usually have: cell wall, cell membrane, ribosomes, genetic material, cytoplasm, and flagella or cilia • Examples: bacteria and archae • Reproduce through binary fission • Get energy through photosynthesis, chemosynthesis, (inorganic chemicals) or digesting other organisms

  2. Eukaryotes – What are they? • Cells with a nucleus and other membrane-bound organelles that perform special functions • Always have a nucleus • May also have: chloroplasts, Golgi apparatus, lysosomes, mitochondrion, plastids, rough endoplasmic reticulum, smooth endoplasmic reticulum, vacuoles, and vesicles • Examples: fungi, protists, plant and animal cells • Reproduce by mitosis or meiosis • Get energy through photosynthesis or by digesting other organisms.
