    Study Notes

    Asexual Reproduction

    • Asexual reproduction is the formation of identical offspring in the absence of a mate.
    • Examples of organisms that reproduce asexually include Bacteria, Protists, Amoebas, hydra, yeast, coral, flatworms, pothos, and strawberry plants.
    • There are different types of asexual reproduction, such as binary fission (or mitosis), budding, fragmentation, and vegetative propagation.

    Heredity and Genes

    • Heredity is the passage of biological traits from parents to offspring through the inheritance of genes.
    • Traits are genetically determined characteristics.
    • Genes are segments of DNA occupying a specific place on a chromosome.
    • DNA is the basic unit of heredity.
    • Offspring are new living things that come from one or more parents, also called children.

    Nature vs. Nurture

    • Nature refers to the traits inherited from parents' genes present at birth.
    • Nurture refers to the effects of the environment on an organism's development.
    • Both nature and nurture contribute to who an individual becomes.

    Sexual Reproduction

    • Sexual reproduction involves the union of male and female reproductive cells (gametes).
    • Gametes are sex cells with half the number of chromosomes as a normal body cell; they are haploid.
    • Offspring produced through sexual reproduction are genetically varied.
    • Fertilization is the process where male and female gametes combine to form a zygote (diploid cell).

    Advantages of Asexual Reproduction

    • Large numbers of offspring are produced.
    • No energy is needed to find a mate.
    • Little or no parental care is required.
    • Only one organism is needed for reproduction.

    Disadvantages of Asexual Reproduction

    • Offspring are clones, which makes them susceptible to the same diseases or harmful mutations.
    • Extreme temperatures can wipe out entire colonies.
    • Offspring compete for resources.

    Advantages of Sexual Reproduction

    • Genetic variation allows organisms to survive in changing environments.

    Disadvantages of Sexual Reproduction

    • Takes more time (finding a mate, fusion of gametes)
    • Exposure to conditions (disease, predators, etc.) when finding a mate
    • Fewer offspring
    • Offspring take longer to mature.
    • Offspring may need to be raised.

    Meiosis

    • Meiosis is a type of cell division that produces four haploid daughter cells from one diploid cell.
    • Meiosis involves two divisions, meiosis I, and II.

    Meiosis I Stages

    • Prophase I: The nuclear membrane disappears; chromosomes condense; centrioles move to opposite poles; homologous chromosomes pair up and crossing over occurs.
    • Metaphase I: Spindle fibers attach to chromosomes; homologous pairs line up in the middle of the cell (along the metaphase plate).
    • Anaphase I: Spindle fibers contract, bringing homologous chromosomes to opposite poles of the cell.
    • Telophase I and Cytokinesis: Spindle fibers break up; nuclear membrane may reform; cytokinesis makes two cells, each with a unique chromosomal composition.

    Meiosis II Stages

    • Prophase II: Chromosomes condense if they have relaxed; centrioles move to opposite poles; nuclear membrane (if reformed) breaks down.
    • Metaphase II: Spindle fibers attach to chromosomes; chromosomes line up in the middle of the cell (along the metaphase plate).
    • Anaphase II: Sister chromatids separate and move to opposite poles.
    • Telophase II and Cytokinesis: Spindle fibers break down; nuclear membrane forms; cytokinesis makes four haploid cells.

    Fertilization

    • Fertilization is the fusion of male and female gametes (sperm and egg/ovum).
    • This combination produces a zygote, a diploid cell.
    • In animals, this occurs in the fallopian tube.

    Types of Pollination

    • Self-pollination is when pollen arrives on the stigma of the same flower or another flower on the same plant.
    • Cross-pollination is when pollen lands on the stigma of another flower on a different plant of the same species.
    • Different methods of pollination exist like wind, water, insects, and animals (hummingbirds, dogs, deer).

    How Plants Form Seeds

    • Seven steps to form seeds
      1. Pollination: Pollen grains transfer to the stigma.
      2. Germination: Pollen tube grows towards the egg.
      3. Penetration: Pollen tube makes it to the ovule.
      4. Fertilization: Nuclei of the pollen grain and ovule fuse.
      5. Development: Fertilized ovule becomes a seed.
