Evolution of Seed Plants Quiz

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.
