- Genus
- second to last form of classification more specific.
- Low Power Objective Lens
- always begin with this power lens on a microscope (color red)
- Animalia
- Multicellular, complex organization of many special cells, bring food into the body and digest it, sexual reproduction.
- Plantae
- Organisms acquire energy from sun photosynthesis, chloroplasts, cell walls.
- High Power Objective Lens
- only use fine adjustment know for this particular lens. (Blue)
- Diffusion
- Movement of substance down its concentration gradient from a more concentrated area.
- Class
- 3rd largest and more specific form of classification.
- Descent with modifications
- term Darwin used instead of evolution.
- Mitochondria
- Cellular respiration; releases energy from food molecules and stores.
- Osmosis
- Movement of water across a selectively permeable membrane.
- Species
- last form of classification most specific.
- Ribosome
- Constructed in nucleus site of protein and synthesis.
- Protista
- Live in water or moist habitats. (Differ in many methods of doing things)
- Vestigial Structure
- Structures that are functional in some species but useless in others.
- Active transport
- Movement of substance across a bio membrane against concentration gradient with help of energy input and specific transport proteins.
- Theory Of Natural Selection
- organisms will adapt to their environment (habitat) for survival.
- Selectively permeable membrane
- property of bio membranes that allow some substances to cross into the cell and prevents some from going in.
- The Five Kingdoms
- Plantae, Fungi, Animalia, Protista, and Prokaryotai
- Phylum
- Second largest yet more specific form of classification.
- Kingdom
- Largest and more broad form of classification.
- Family
- 5th largest and more specific form of classification.
- Hypertonic
- A solution where the concentration of solutes outside a cell is greater than the concentration inside.
- Chloroplast
- found only in plants. Has chlorophyll for photosynthesis.
- Hypotonic
- Concentration of solutes outside the cell is less than inside.
- Nucleus
- Membrane Organelle that houses DNA.
- Carbon Dating
- most reliable method of determining the age of rocks.
- Fungi
- Grow directly from reproductive cells called spores. No photosynthesis.
- Order
- 4th largest and more specific form of classification.
- Prokaryotae
- Eubacteria and Archaebacteria, presence of prokaryotic cell (cell that lacks membrane enclosed compartments.
- 100X
- Magnification level with a 10x objective and the eyepiece.
- Vacuole
- structure in cytoplasm. Serves different purposes. Stores water and some form of wastes.
- Predation
- The killing and consuming of prey. A pressure that many organisms face.
- 10X x (O) = TM
- The eyepiece times the objective gives you the total magnification. (Equation).
