internal structure that gives cells their shape and is involved in movement. It is made up of fibers called microtubes and microfilaments: CYTOSKELETON
Small hairlike structures involved in movement., ex Paramecium use cilia to swim. In our lungs, respiratory track cilia is constantly beating upward to remove small debris.: CILIA
DIFFUSES ACROSS MEMBRANE FROM HIGH TO LOW CONCENTRATION. NO ENERGY REQUIRED. EX.,OXYGEN, CARBON DIOXIDE, WATER: MEMBRANE PASSIVE TRANSPORT
TRANSPORT PROTEIN, BRINGS ABOUT FACILITATED DIFFUSION e.g,.steroids, sugars and drugs: MEMBRANE SELECTIVE TRANSPORT
THE ABILITY TO DO WORK: ENERGY
ENERGY IS RELEASED BY CHEMICAL BREAKDOWN OF MOLECULES IN CELLS TO DO WORK IN THE MITOCHONDRIA. - ATP.(ADENOSINE TRIPHOSPHATE): CELLULAR RESPIRATION
ENERGY CURRENCY. A NUCLEOTIDE THAT PERFORMS MANY ESSENTIAL ROLES: ONE OF THE MONOMERS USED IN SYNTHESIS OF RNA AFTER CONVERSION TO DNA, REGULATED MANY BIOCHEMICAL PATHWAYS AND PROVIDES ENERGY FOR MOST OF THE ENERGY CONSUMING ACTIVITIES OF THE CELL: ATP
ADENOSINE TRIPHOSPHATE
PRODUCE THEIR OWN ENERGY: PRODUCERS/AUTOTROPHS eg.,Plants
NEED TO FEED FROM OTHER ORGANISMS: CONSUMERS/HETEROTROPHS
eg.,humans,animals
Glucose+Oxygen+Carbon+Water C6H12O6+6O2+6CO2+6H2O+: Celluar Respiration Formula which makes ATP (energy)
Carbon+Water+ATP+Glucose+Oxygen 6CO2+6H2O+ENERGY+C6H12O6+6O2: PHOTOSYNTHESIS
SITE OF PHOTOSYNTHESIS IN PLANTS (ENERGY CONVERSION): CHLOROPLAST
TWO TWISTED CHAINS OF PROTEINS THAT CONTRACT TO CAUSE MOVEMENT. LIKE A TWIST ROPE: MICROFILAMENTS
INSIDE NUCLEUS-DNA (BLUEPRINT FOR LIFE)-MRNA-SENT OUT WITH INSTRUCTIONS TO RIBOSOMES-CARRIES OUT INSTRUCTIONS AND CREATES PROTEINS: FLUID MOSAIC MODEL CELL
HOLLOW TUBES LIKE PLUMBING PIPES, THEY ARE TRACKS FOR ORGANELLES TO MOVE ALONG: MICROTUBULUS
three domains of life: BACTERIA
ARCHAEA
EUKARYOTA
MOST ARE MICROSCOPIC AND UNICELLULAR WITH SIMPLE CELL STRUCTURE NO NUCLEUS, NO CHLOROPLASSTS OR MITOCHONDRIA. PROKARYOTES: BACTERIA

CYANOBACTERIA
HETEROTROPHIC BACTERIA
SINGLE CELLED ORGANISMS LACKING NUCLEI, KNOWN AS MONERA, ORIGINALLY DESCRIBED IN EXTREME ENVIRONMENTS BUT HAVE SINCE BEEN FOUND IN ALL TYPES OF HABITATS.: ARCHAEA

HALOPHILES, THERMOPHILES
COMPLEX CELL IN WHICH GENETIC MATERIAL IS ORGANIZED INTO MEMBRANE-BOUND NUCLEUS. COMPRISE ANIMALS, PLANTS AND FUNGI WITH ARE MOSTLY MULTICELLULAR AS WELL AS PROTISTS WHICH ARE UNICELLULAR: EUKARYOTE

ANIMALS,PLANTS,FUNGI,PROTIST
MAY LOOK DIFFERENT AND FUNCTION VERY DIFFERENT IN DIFFERENT SPECIES BUT THEY EXHIBIT FUNDAMENTAL SIMILARITIES BECAUSE THEY EVOLVED FROM THE SAME STRUCTURE THAT EXISTED IN A COMMON ANCESTER.: HOMOLOGUS STRUCTURES
STRUCTURES WITH SIMILAR ORIGINS: DIVERGENT EVOLUTION
CERTAIN STRUCTURES ARE SUPERFICIALLY SIMILAR BUT THE SPECIES ARE FROM DIFFERENT EVOLUTIONARY BRANCHES EG.,BAT WINGS , INSECT WINGS: CONVERGENT EVOLUTION
COMPARES THE GENES AND GENES PRODUCTS (PROTEINS): MOLECULAR BIOLOGY
THE SCIENTIFIC SEARCH FOR CLADES. IT IS A DISTINCTIVE BRANCH ON THE EVOLUTIONARY INNOVATIONS THAT DEFINE: Cladistics Analysis
two main points: Modern species evolved from ancesteral forms. Natural selection is the main mechanism for evolution Wrote "the origins of Life": Darwin Two Main Points
CARBON HYDROGEN OXYGEN NITROGEN PHOSPHRUS SALINE: C H O N P S
FOUR STAGE HYPOTHESIS OF LIFES ORIGINS: 1. ABIOTIC (NON LIVING)
2. ABIOTIC SYNTHESIS OF POLYMERS.
3. ORIGINS OF SELF-REPLICATING MOLECULES
4. FORMULATION OF PRE-CELLS
LIFE EVOLVED DIVERSITY VIA NATURAL SELECTION OBSERVATION:OVERPRODUCTION AND THE STRUGGLE FOR SURVIVAL LED TO INDIVIDUAL VARIATIONS: DARWIN 1859
THE ORIGINS OF SPECIES
A POPULATION OF ORGANISMS CAN CHANGE OVER THE GENERATIONS IF INDIVIDUALS HAVE CERTAIN HERITABLE TRAITS THEY LEAVE MORE OFFSPRINGS THAT OTHER INDIVIDUALS LACKING THOSE SPECIFIC HERITABLE TRAITS: NATURAL SELECTION
FAMOUSE TRIP: "HMS BEAGLE" INFLUENCED BY LYELL. LYELL A GEOLOGIST PROPOSED THAT THE EARTH IS MUCH OLDER THAN 6000 YEARS OLD.: DARWIN: OVERPRODUCTION
INDIVIDUAL VARIATIONS
