Gametophyte

Science / Biology / Gametophyte: The haploid stage of a plant exhibiting alternation of generations, generates gametes by the process of mitosis.

Microgametophyte

Science / Biology / Microgametophyte: Stage of the plant life cycle that develops from or within a microspore. The microgametophyte produces sperm in specialized structures known as antheridia. MORE

Flowers

Science / Biology / Flowers: The reproductive structures in angiosperm sporophytes where gametophytes are generated. MORE

Prothallus

Science / Biology / Prothallus: In ferns, a small heart-shaped bisexual gametophyte. MORE

Meiosis

Science / Biology / Meiosis: Cell division in which the chromosomes replicate, followed by two nuclear divisions. Each of the resulting gametes (in animals, spores in plants) receives a haploid set of chromosomes. Reduction/divis MORE

Ovule

Science / Biology / Ovule: In seed plants, a protective structure in which the female gametophyte develops, fertilization occurs, and seeds develop; contained within the ovary. Structures inside the ovary of the flower within w MORE

Seed

Science / Biology / Seed: Structure produced by some plants in which the next generation sporophyte is surrounded by gametophyte nutritive tissues. An immature sporophyte in an arrested state of development, surrounded by a pr MORE
