  • Eukaryotic Motility

    •more appendages for motility.

    •Flagella are similar to those in prokaryotic cells, but whip back and forth to provide motility rather than spinning. 

    •Cilia are much shorter than flagella but have similar structure.  Far greater in number

  • Eukaryotic Glycocalyx

    Like prokaryotes, eukaryotes have slime layers and capsules

    •Protection

    •Communication

    •Adherence

  • Eukaryotic Cell Wall/Membrane

    •Some eukaryotes (fungi, algae, plants) have cell walls, but there is tremendous variability

    •Animal cells, many protists, lack cell walls

    •Cell membranes are like prokaryotic cell membranes in structure and function

    •Eukaryotic membranes typically contains sterols to increase the strength of the membrane (especially in the absence of cell walls)

  • Nucleus:  Control center

    •DNA in nucleus is transcribed to RNA, which moves to cytoplasm through nuclear pores

  • Eukaryotic Ribosomes

    •Prokaryotic ribosomes consist of 30S and 50 subunits, which together equal 70S

    •Eukaryotic ribosomes consist of 40S and 60S subunits, which together equal 80S

  • Endoplasmic Reticulum

    phosphid and protein

  • Golgi Body (Apparatus)

    •Receives proteins from ER

    •Modifies proteins by adding sugars

  • Proteins Pathway

    Nucleus-> ER->Golgi body->Cell membrane

  • Lysosomes

    •During phagocytosis, food is engulfed into a food vacuole

    •contain digestive enzymes

    • fuse with the food vacuole to produce a digestive vacuole (or phagolysosome)

    •How you each lunch if you’re an amoeba

    •White blood cells in the body phagocytize bacteria and other pathogens

  • Mitochondria

    •The powerhouse of the cell

    •Converts unusable energy stored in various organic molecules (sugars, fats, proteins) to usable ATP

    •Mitochondria were once free-living organisms

    •own DNA

    •own (70S) ribosomes

    •Roughly the size and shape of a prokaryotic cell

  • Chloroplast

    •Converts energy from sunlight into sugars

    •Found in algae (and plants)

    •Chloroplasts were also once free-living organisms

    •Have their own DNA

    •Have their own (70S) ribosomes

    •Roughly the size and shape of a prokaryotic cell

  • Cytoskeleton

    •Anchors organelles in place within the cytoplasm

    •Allows for movement of some cell types

  • Fungi include

    Yeasts (non-filamentous) and Molds (filamentous)both-mycelium

  • Yeast reproduce by

    budding

  • septate vs non septate

    septate- septum with pores

  • Molds reproduce by

    spores

  • Sporangiospores are borne in

    sporangia on reproductive hyphae

  • Fungi are classified according to the type of sexual spores they produce

    •Zygomycota (zygospores)

    •Ascomycota (ascospores)

    •Basidiomycota (basidiospores)

    •Chytridiomycota (motile spores)
