• Mitosis


  A type of cell division that used Somatic/body cells
• In mitosis 2 daughter cells were produced
• Interphase


  1. G1 phase - Cell growth occurred in preparation to the next phase

  2. G2 phase - The cell synthesizes organelles and other materials

  3. S-Phase - The DNA replicated
• Resting stage


  This process happen in the INTERPHASE because the cell is not dividing
• Prophase


  The chromosome in the nucleus condense
• Metaphase


  The chromosome aligned at the center
• Anaphase


  The spindle fibres pull one set of chromatids
• Telophase


  Chromosome are uncoiled and new nucleus are form
• Meiosis


  A type of cell division is used to produce sex cells such as egg cell and sperm cell
• Spermatogenesis


  Production of sperm cell during meiosis
• Oogenesis


  Production of egg cell during meiosis
• Gregor Mendel was an Augustinian monk that is known for being the "Father of Genetics"
• Mendel Pea plant Characteristics(D,R)


  • Flower Position: Axial, terminal
  • Plant height: Tall, short
  • Flower color: purple, white
  • Pod color: Green, yellow
  • Pod shape: inflated, constricted
  • Seed color: Yellow, green
  • Seed shape: round, wrinkled
• Homozygous


  The genes are either both Capital letters or both small letters
• Heterozygous


  The genes are never the same, one is capital and one is small letter
• Dominant Trait

  If a gene contains a Capital letter either Heterozygous or Homozygous
• Recessive trait

  If a gene doesn't contain a capital letter automatic it is a recessive trait
• Law of segregation

  Each gene separates from each other so that each gamete carries only one allele from each gene
• Law of Dominance

  Statest that in a heterozygous gene pair, the dominant trait will mask the recessive trait
• Biodiversity


  Coined from the word "biological diversity" that means Variety of life
• Carolus Linnaeus is known as the "Father of Modern Taxonomy"
• Ecosystem Diversity

  An environment where organisms interact with one another
• Genetic Diversity

  The total different number of characteristics in the genetic makeup of a species that help them to survive
• Binomial Nomenclature

  It is used by the Scientists to name organisms. It consists of two parts (Genus and Species)
• Scientific name

  The name given to organisms who are already classified
• Biodiversity's primary cause of biodiversity loss is habitat loss because many organisms cannot survive to different environment
• One of the causes of losing of habitat is over population because the habitats that intended for animals were occupied by the humans due to increase in number of human population
• To reduce over population one recommendation is family planning programs
• What are the 8 characteristics in Mendel pea plant?

  Flower position, Plant height, Flower color, Pod color, Pod shape, Seed color, Seed shape
• What are the 8 characteristics in Mendel pea plant?

  Flower position, Plant height, Flower color, Pod color, Pod shape, Seed color, Seed shape
• Kingdom - classification gets more specific after domain
• Domain - highest taxonomic rank
• Phylum - Divided into two ( vertebrate and invertebrate )
• Class - More specific than phylum
• Order - Genus can be grouped into orders
• Family - classified between ORDER and GENUS
• Genus - More specific than family
• Species - smallest category of living organisms
• Producer - produces food
• Most plants are all producer
