    Study Notes

    Seed Plants

    • The primary function of a seed is to nurture and protect the embryo of a seed plant.
    • The phylum of extant seed plants that includes non-flowering plants is Gymnosperms.

    Reproduction in Angiosperms

    • The main function of the carpel is to produce ovules and protect the embryo sac.

    Pine Reproduction

    • The process by which male gametophytes develop in pine reproduction is called microsporogenesis.
    • The male gametophyte develops from the microspores of a pine.

    Double Fertilization

    • During double fertilization in angiosperms, one sperm fertilizes the egg, while the other sperm fertilizes the central cell, resulting in a triploid endosperm.

    Seed Structure

    • The function of the integument in seed plants is to protect the ovule and develop into the seed coat.

    Gymnosperms

    • The type of seed plant that lacks flowers and has the ovule exposed on a scale is a Gymnosperm (e.g., conifers).
    • The main product obtained from conifers is wood, resin, and turpentine.

    Angiosperm Carpels

    • The three major regions of the carpel in angiosperms are the stigma, style, and ovary.
