Macromolecules Quiz

Complete the quiz silently

When you are finished, place quiz facedown

on desk

When everyone is finished, pass quizzes

foward

Cells Levels of Organization

Cells:A. All life has ≥1 cell(s)B. Basic unit of life (anything before not living)C. Cells come from living cells

Atoms Molecules Monomers Macromolecules/Polymers

Cells Organisms

CellsCells

Prokaryotic

•Single Cell•No Nucleus•Simple

Eukaryotic•Single or Multicellular•True Nucleus•Complex

Bacteria•Early life•Found almost everywhere

Archaea•Extreme conditions (salt, heat, no oxygen)

Animal•Multicellular•Digest their food•Can move independently Plant

•Multicellular•Photosynthesis for food•Rigid cell walls•Chloroplasts

Fungi

•Mostly multicellular•Rigid cell walls•Consume dead matter

Protist•Mostly unicellular•Don’t fit in, but plant-like, animal-like, or fungi-like

Cells Prokaryotic Cells (Bacteria, Archaea)

Ribosome- Makes proteins

Capsule- Additional Protection

Cell Wall- Rigid Shape

Plasma/Cell Membrane-Encloses cell-Regulates entrance & exit of substances

Flagellum (pl. Flagella)- Movement

*Any cell part is called an “organelle”

Pilus (pl. Pili)- Attach to other bacteria

Nucleoid (DNA)- NO membrane around DNA

Cytoplasm-Gel-like fluid

Cells Eukaryotic (Animal, Plant, Fungi, Protist)Centrioles

-Organize cell during division

Rough Endoplasmic Reticulum-Transports & folds proteins

Golgi Apparatus-Packages macromolecules to be shipped out of cell

Vacuole (Animal)-Store food, water, waste & minerals (small)

Smooth Endoplasmic Reticulum-Lipid Synthesis

Mitochondrion (pl. Mitochondria)-Provides energyFlagellum (sometimes)

Peroxisome-Breaks down fatty acids

Cytoplasm

Lysosome-Enzymes breakdown macromolecules

Cytoskeleton-Structure & internal movement

Plasma/Cell Membrane

Ribosomes

Zoom-In on Nucleus

Nucleus-Regulates all cell activity-Membrane bound-Contains DNA

Cells

Nuclear Pore-Exchange materials

Nucleolus-Synthesizes ribosomes

Nuclear Envelope-Encloses DNA

Cells Eukaryotic (Animal, Plant, Fungi, Protist)Plasmodesmata-Transport & communication b/twn cells

Vacuole (Plant)-Store food, water, waste, & minerals (large)

Peroxisome

Mitochondrion

Rough ERSmooth ER Ribosomes

Plasma/Cell Membrane

Cell Wall-Rigid shape, prevents bursting from too much water

Nucleus-Nucleolus-Nuclear Pore-Nuclear Envelope

Chloroplast-Use sunlight to synthesize sugar (photosynthesis)

CytoskeletonCytoplasm

Practice Split paper into 4 columns

Under “Cell”, indicate if it is prokaryotic, eukaryotic (animal), or eukaryotic (plant)
