Life Science : Genes & Molecular Machines
Types of Cells
Prokaryotic Cells
An organism whose cells do not have an enclosed nucleus
Examples : bacteria and archaea
Eukaryotic Cells
Cells with a nucleaus (surronded by its own membrane) and other internal orgainsms
Examples : fungi, plants and animals
Heredity
Phenotype
An organims physical apperance or visable traits
Examples : hair color, eye color, height, skin color, etc.
Genotype
An organism genetic makeup or allele combinations
Combined of recessive and dominant alleles from both parents
Cell Divison
Meiosis
Stages : prophase, metaphase, anaphase, and telophase then repeated again for the result of four daughter cells
A type of cell division that results in four daughter cells each with 1/2 the number of chromosomes of the parent cell, as in the production of gametes and plant spores.
Mitosis
Body cell division in which the nucleus divides containing the same number of chromosomes.
Stages : prophase, metaphase, anaphase, and telophase
Flowering, Plants and Seeds
Pollinating Flowers
Flowers can self pollinate - Pollen being brought from a pollinator from the another of one plant to the stigma of the same plant.
Flowers can cross pollinate - Pollen being transferred by pollinators goes from the anther of one plant to the stigma of another.
Seed Dispersal
Animals, Wind, Water, and Mechanical Pulposion are ways of seed dispersal.
Seeds need to be dispersed from the parent plant because if they grow by their parent there will not be enough nutrients for both organisms to survive.
