GENERAL BIOLOGY 2

Cards (85)

  • Allows a living thing to reproduce without another member of its species

    Asexual reproduction
  • requires two genetic material, combination of haploid gametes
    sexual reproduction
  • The parent organism divides into two nearly equal parts.
    Binary Fission
  • An offspring develops as a growth on the parent organism and eventually separates.
    Budding
  • The parent organism breaks into fragments, each capable of growing into a new organism.
    fragmentation
  • An unfertilized egg develops into a new individual.
    Parthenogenesis
  • New plants grow from parts of the parent plant, such as runners or tubers.
    Vegetative Reproduction
  • Sperm and egg cells fuse to form a zygote.
    Gametic Fusion
  • The fusion of male and female gametes.
    Fertilization
  • The process where gametes are formed, involving cell division reducing the chromosome number by half.
    Meiosis
  • These are the primary organs of the male reproductive system responsible for producing sperm cells and male hormones, such as testosterone.
    Testes
  • A coiled tube located behind each testis where sperm
    Epididymis
  • A long tube that carries sperm cells from the epididymis to the prostate gland through muscular contractions.
    Vas deferens
  • A glandular organ that produces fluid for semen, providing nourishment and protection for sperm cells.
    prostate gland
  • Two glandular organs that release fluid adding nutrients and balancing the pH of semen.
    Seminal Vesicle
  • Small glands that release a clear fluid to cleanse the urethra and protect sperm cells from any remaining acidic urine in the urethra.
    Bulbourethral Glands
  • the external organ of the male reproductive system containing the urethra and delivering semen during intercourse
    penis
  • also known as seminal fluid
    semen
  • It involves the monthly series of changes in the ovaries and the uterus, preparing the body for pregnancy
    menstrual cycle
  • In this cycle, females experience a period of sexual receptivity (estrus) when they are fertile
    estrous cycle
  • refers to the series of events that occur in the ovaries of female mammals
    ovarian cycle
  • Some animals, such as deer and birds, have specific breeding seasons when they are more likely to reproduce.
    breeding season
  • They do not have a specific breeding season and can mate and reproduce at any time.
    Continuous reproduction
  • Some organisms, like aphids and rotifers, exhibit cyclic parthenogenesis, where they alternate between sexual and asexual reproduction in response to environmental conditions.
    Cyclic parthenogenesis
  • responsible for supporting the plants as well as for the storage
    xylem
  • for translocation
    phloem
  • central pumping organ
    heart
  • heart contractions
    systole and diastole
  • the relaxation
    systole
  • the driving force for blood circulation
    diastole
  • conduits that transport blood throughout the body
    blood vessels
  • carry oxygenated
    arteries
  • carry deoxygenated
    veins
  • facilitate exchange of gasses
    capillaries
  • blood flows from heart to lungs
    pulmonary circulation
  • blood flows from heart to body tissues
    systemic circulation
  • maintain the levels of hormones in the body with desired limits
    feedback mechanism
  • works to reverse deviations, stabilizing and maintaining homeotasis
    negative feedback mechanism
  • amplify conditions, pushing the system
    positive feedback mechanism
  • self regulating process
    hemeostasis
