Mass is measured by:
A balance scale
Cell theory:
All organisms are composed of cells. All cells arise from preexisting cells. All hereditary components of organisms occur in cells
Nucleolus
Assembles proteins and RNA that will form ribosomes

Prokaryotic cells:
Consist of bacteria
Lysosome
Contains enzymes to digest metabolic waste and damaged cells. Absent in plant cells.
Nucleus
Control center of the cell. Contains hereditary material (DNA)

Characteristics of Eukaryotic cells
Larger, Have nucleolus, have membrane-bound nucleus and organelles, have cytoskeleton
Last Good Monday
Liter gram meter
Central vacuole
Maintains hydrostatic pressure in plant cells. Absent in animal cells
Endoplasmic Reticulum
Membranous channels that allow materials to move within in the cell
Last two units
Micro and nano
Milk
Milli
Cilia and flagella
Move fluid over cell surface or move the cell through fluid
Separates the nucleus from the cytoplasm of the cell. Controls the movement of material in and out of the nucleus
Nuclear membrane
Centriole
Organization of microtubule system used in cell division. Absent in plant cells
Controls movement in and out of cell
Plasma membrane
Characteristics eukaryotic and prokaryotic cells share:
Plasma, membrane, chromosomes, ribosomes, cytoplasm
Cell wall
Protection and structure. Absent in animal cells
Chloroplast
Site of photosynthesis. Found only in plant cells
Characteristics of prokaryotic cells
Smaller, no nucleolus, no membrane-bound nucleus and organelles, no cytoskeleton
Rough ER
Studded with ribosomes. Folding of proteins after being made by ribosomes
Smooth ER
Synthesizes lipids and steroids

Eukaryotic cells:
consist of protists, fungi, plant, and animals
Finding the volume

Mitochondria
"Powerhouse of the cell." Site of energy production by aerobic respiration by forming ATP
Three things plant cells have that animal cells don't:
1. Cell wall 2. Central Vacuole 3. Chloroplasts
Two things animal cells have that plant cells do not have:
1. Centrioles in centrosome 2. Lysosomes
3 types of microscopes:
1. Compound 2. Dissecting 3. Electron
Twp types of slides used in the course
