The Five Kingdoms

Plantae, Fungi, Animalia, Protista, and Prokaryotai

Prokaryotae

Eubacteria and Archaebacteria, presence of prokaryotic cell (cell that lacks membrane enclosed compartments.

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.

Fungi

Grow directly from reproductive cells called spores. No photosynthesis.

Protista

Live in water or moist habitats. (Differ in many methods of doing things)

Nucleus

Membrane Organelle that houses DNA.

Ribosome

Constructed in nucleus site of protein and synthesis.

Mitochondria

Cellular respiration; releases energy from food molecules and stores.

Chloroplast

found only in plants. Has chlorophyll for photosynthesis.

Vacuole

structure in cytoplasm. Serves different purposes. Stores water and some form of wastes.

Hypertonic

A solution where the concentration of solutes outside a cell is greater than the concentration inside.

Hypotonic

Concentration of solutes outside the cell is less than inside.

Diffusion

Movement of substance down its concentration gradient from a more concentrated area.

Osmosis

Movement of water across a selectively permeable membrane.

Selectively permeable membrane

property of bio membranes that allow some substances to cross into the cell and prevents some from going in.

Active transport

Movement of substance across a bio membrane against concentration gradient with help of energy input and specific transport proteins.

Vestigial Structure

Structures that are functional in some species but useless in others.

Predation

The killing and consuming of prey. A pressure that many organisms face.

Kingdom

Largest and more broad form of classification.

Phylum

Second largest yet more specific form of classification.

Class

3rd largest and more specific form of classification.

Order

4th largest and more specific form of classification.

Family

5th largest and more specific form of classification.

Genus

second to last form of classification more specific.

Species

last form of classification most specific.

Carbon Dating

most reliable method of determining the age of rocks.

Descent with modifications

term Darwin used instead of evolution.

Theory Of Natural Selection

organisms will adapt to their environment (habitat) for survival.

Low Power Objective Lens

always begin with this power lens on a microscope (color red)

High Power Objective Lens

only use fine adjustment know for this particular lens. (Blue)

100X

Magnification level with a 10x objective and the eyepiece.

10X x (O) = TM

The eyepiece times the objective gives you the total magnification. (Equation).
