alternation of generations
the shift between haploid and diploid
multicellular diploid (2N) phase, spore producing plant
multicellular haploid (N) phase, gamete producing plant
plant group with specialized reproductive organs enclosed by nonreproductive cells.
tubes hardened with a substance called lignin that carry water
eggs are produced in
sperm produced in
the spore capsule. Inside, spores are produced by meiosis
vascular plants, contain a specialized water-conducting cell
hollow tubelike cells with thick cell walls. in tracheophytes and xylem
tissue that carries water upward from the roots to every part of the plant
a transport tissue that transports solutions of nutrients and carbohydrates produced by photosynthesis.
a plant embryo and food supply, encased in a protective covering. The plant within the seed is a diploid cell.
bear seeds directly on scales of cones
bear seeds in flowers inside a layer of tissue that protects the seed.
the entire male gametophyte Carried to the female reproductive structure by wind or animals (bees)
the transfer of pollen from the male repro structure to the female repro structure
surrounds and protects the embryo and keeps the contents of the seed from drying out.
surround and protect the seed in a flower
a structure containing one or more matured ovaries. The wall of the fruit helps disperse the seed inside of it, as animals eat andwaste it, carrying them away from the parent plant
One year life span, grow from seed to maturity.
Die in one growing season
ex.- marigolds, petunias, pansies, wheat
2 growing season life span
ex.- parsley, foxglove, celery
Over 4 year life span
herbaceous stemmed die in winter and grow back in spring
ex.- peonies, palm trees, honeysuckle
