  • Front
  • Back
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
