Father of Biology
Aristotle
Biology came from two Greek words
Bios and logos
Means study of life
Biology
Hierarchy of Life (AMOCTOSO)
Atom
Molecule
Organelle
Cell
Tissue
Organ
System
Organism
Study of cells
Cytology
Two types of cells that make up every organism
Prokaryotic cells
Eukaryotic cells
Bacteria and archaebacteria. Do not contain a nucleus.
Prokaryotic cells
Protist, fungi, plant, animal. It contains a true nucleus.
Eukaryotic cells
hair-like structures. e.g. linings in the fallopian tube.
cilia
Tail that cells have
flagellum/ flagella
DISCOVERED CELL FROM A CORK from bark of an oak tree
Robert Hooke
He coined the term “cell” meaning small room
Robert Hooke
Discovered CELL’S NUCLEUS
Robert Brown
Not living, inert chemicals (inactive, active only once inside the cell)
Virus
Protein shell that protects the virus’ DNA or RNA
Capsid
Classification and naming of organisms
Taxonomy
8 levels of Taxonomic Classification (Dear King Philip, Come Over For Good Spaghetti)
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species
Father of Modern Taxonomy. He proposed the BINOMIAL NOMENCLATURE.
Carolus Linnaeus
Live in various places, in the most SEVERE ENVIRONMENTS. not bacteria.
Kingdom Archaebacteria
METHANOGENS, HALOPHILES, THERMOPHILES
Kingdom Archaebacteria
referred to as TRUE BACTERIA or called the bacteria group.
Kingdom Eubacteria or Monera
Streptococcus
Kingdom Eubacteria or Monera
Diatoms, Algae (green, golden, brown, red algae)
Kingdom Protista
Entamoeba Histolytica (Amoebiasis) and Plasmodium (Malaria)
Kingdom Protista
Molds, mushroom, yeasts, MICROSPORIDIA
Kingdom Fungi
Two major groups of Kingdom Animalia
Invertebrates and Vertebrates
No backbones
Invertebrates
With backbones
Vertebrates
Have stinging cells (nematocyst) / poison. Example: JELLYFISH AND CORAL
Cnidaria
Jointed legs; segmented bodies. Examples: Insects: MOSQUITO, butterflies; Crustaceans: crab, shrimps, lobsters; Arachnid: SPIDERS; centipede; milipede
Arthropoda
Insects shed off their old cuticle to grow in size
Molting or Ecdysis
Roundworms; unsegmented. Example: pinworm, ascaris, hookworm, filarial worm
Nematoda
FLATWORMS: worms have soft tissues; unsegmented. Example: flukes, tapeworms, planaria
Platyhelminthis
Segmented worms. Example: LEECH and EARTHWORMS
Annelida
Earthworms are ___ with both female and male organs found in the same worm
Hermaphroditic
Leeches promote ___ anticoagulation that prevents blood clotting.
Anticoagulation
With soft bodies usually with shells. Example: SQUIDS, CLAMS, SNAILS, OCTOPI
Mollusca
Spiny body. Example: SEA STAR, SEA URCHIN, sand dollars, sea cucumber, brittle star
Echinodermata
Fish, amphibians, reptiles, birds or aves, mammals
Chordata
Scales, gills, and fins: shark, lampreys
Fish (Pisces)
Means two lives
Amphibia
Frog and salamander
Amphibians
Eggs, scaly bodies: CROCODILE, SNAKE, TURTLE, lizards
Reptiles
Creeping
Reptilia
2 scaly legs, wings, feathers: PENGUIN AND OSTRICH
Birds (Aves)
Mammary glands, hairs, milk: HUMAN, PLATYPUS, MARSUPIAL
Mammals
Marine mammals with long ivory tusks living in arctic environment
Walrus
Two big groups of Kingdom Plantae
Nonvascular
Vascular
Do not have tissues to transport water and food
Nonvascular
Without tissues to transfer water and food
Vascular
Study of plants
Botany
Vascular plants can be
Seedless vascular plants
Seed vascular plants
Under seed vascular plants are
Angiosperms
Gymnosperms
Vascular plants are
Xylem
Phloem
Conducts most of the water and minerals
Xylem
Distributes sugars/ food and other organic products
Phloem
Best example of seedless vascular plants
Ferns
or FLOWERING PLANTS, most abundant and widely distributed plants. bears fruit to protect the seed.
Angiosperms
or CONE BEARING PLANTS. have NAKED SEEDS. seeds are not enclosed by fruit. example: CONIFERS
Gymnosperms
Reproductive organ of a flowering plant
Flower
transfer of pollen grains from the anther to the stigma of the flower
Pollination
Pollination from one plant to another
Cross pollination
Pollination from same flower or plant
Self-pollination
Parts of a flower
Sepals
Petals
Stamen
Carpel
Called CALYX, protect the flower bud before it opens
Sepals
Called COROLLA, it attracts a particular pollinator
Petals
Male part consisting AFP
Stamen
AFP
Anther, Filament, Pollen Grains
Female part consisting SOSO
Carpel or Pistil
SOSO
Stigma, Ovary to fruit, Style, Ovule to seed
Vegetative reproduction
Asexual reproduction
or STOLON Horizontal stems, new roots and shoots develop at the node. Examples: strawberry, bermuda grass, BAMBOO GRASS known as the longest grass
Runners
Underground stems, the “EYES” are the stem’s nodes, containing cluster of buds. Example: POTATO
Tubers
Horizontal underground stem. Example: GINGER
Rhizomes
Shortened, compressed underground stems. Example: ONION AND GARLIC
Bulbs
Underground stems. Example: TARO (COLOCASIA)/ GABI
Corms
Carrots, sweet potatoes (camote), and cassava
Underground roots
Parent organism producing offspring by GROWING A REPLICA in the form of an OUTGROWRTH called BUD. Example: HYDRA AND YEAST
Budding
Separated pieces of the PARENT ORGANISM DEVELOPING TO AN INDIVIDUAL. Example: Sea star, flatworms
Fragmentation
Asexual reproduction in bacteria
Binary fission
