  • Definition: Cell

    The basic functional and structural units of organisms.

  • All cell contains ____

    • Plasma membrane

    • Cytosol

    • Chromosomes (DNA)

    • Ribosome

  • Definition: Prokaryote

    Small, simple single-cell organisms

    • Domain: Bacteria & Archea

    • DNA in the nucleiod region

    • Generally 1000~ smaller than the eukaryotes

  • Definition: Eukaryote

    Larger, more complex, multi-cellular organisms

    • Domain: Protists, Fungi, Animals, and Plants

    • DNA stored in the nucleus

    • Contain membrane-bound organelles

  • Definition & Purpose: Compartmentalization

    Different chemical reactions occurs in different place

    • Occurs in Eukaryotic cells - Prokaryotes have specialized regions

    Purpose:

    • increase SA for reactions to occurs

    • Minimize overlapping reactions

      • Increase efficiency

  • List unique cell's components: Plant

    • Cell wall

    • Central Vacuole

    • Chloroplast

    • Plasmodesmata

  • List unique cell's components: Animals

    • Lysosome

    • Centrosome

    • Flagella

  • Function: Nucleus

    The entire organelle that contain genetic materials

  • Function: Nuclear envelope

    A specialized double-membrane that surrounds the nucleus

    • Has pores for material regulation

    • Continuous with the ER membrane

  • Function: Nucleolus

    Dense region in the nucleus where ribosomal RNA (rRNA) is synthesize

    • rRNA + protein forms subunits to the ribosome.

  • Function: Ribosomes

    *not really an organelle

    Complexes made of ribosomal RNA and protein

    Purpose
