Aleurone: A protein uncovered in the endosperm of countless seeds. It forms the outermost class of the particle coat in part grains. During seed germination, hydrolysis in the seed causes the aleurone cell to break down into amino acids.

Angiosperms: A division of the plant kingdom that includes all flower plants; vascular plants in which double fertilization occurs resulting in breakthrough of fruit containing seeds. Split into two significant groups, monocotyledons and also dicotyledons.

Anther: The pollen-bearing body organ at the apex the the stamen.

Auxin: A team of plant development hormones i beg your pardon stimulate cell division, enlargement, apical dominance, source initiation, and flowering.

Carpel: (See Pistil)

Coleoptile: safety sheath covering the shooting apex the the embryo in monocotyledenous plants.

Cotyledons: The part of the tree embryo from which leaves room formed. Monocotyledons have one cotyledon in every seed; dicotyledons have two. The cotyledons of countless plants emerge over the ground after germination, and become photosynthetically energetic and are vital to early growth and establishment.

Double Fertilization: A characteristic of angiosperms in i m sorry a pollen tube carries 2 sperm cell to the female gametophyte in the ovule.

Endosperm: The organization containing save food in a seed the surrounds the embryo and also is at some point digested by the embryo together it grows.

Flower: The reproductive structure uncovered on flowering tree (angiosperms) that contains male pollen-producing stamens and also female egg-producing pistils.

Fruit: The ripened ovary (or ovaries) the a flower, and contains the seeds. Discovered in angiosperms.

Gametophyte: The haploid, gamete-producing phase in the life cycle of a plant.

Germination: The procedure that occurs once a seeds or spore begins to prosper into a maturation plant; germination requires moisture, oxygen and a an ideal temperature

Gibberellic Acid: A growth stimulating and also dormancy breaking tree hormone.

Ground Meristem: The an easy primary tissue of the growing tip the a stem or root, not included the epidermis and vascular bundles, which provides rise to the cortex, rays, and pith.

Hypocotyl: The identical of the stem in a young seedling. The vegetative organ in between the root and also the cotyledons, i m sorry is responsible for initial upward elongation growth.

Inflorescence: A basic term for a swarm of flower on one plant. One inflorescence can be an extremely loosely arranged, strictly bunched, or anything in between.

Leaf Primordia: Young leaves, recently created by the shoot apical meristem, located at the reminder of a shoot.

Megaspore: The larger of the 2 kinds of spores created in the sexual life bicycle of a plant, providing rise come the female gametophyte.

Meristem: Plant organization that stays embryonic as long as the tree lives, allowing for indeterminate growth.

Microspore: The smaller sized of the two kinds of spores produced in the sex-related lifecycle that a flower plant, giving rise to the male gametophyte.

Ovary: The section of a carpel in i m sorry the egg-containing ovules develop.

Ovule: A framework that develops in the tree ovary and also contains the mrs gametophyte.

Pistil: The mrs reproductive framework of a flower, consisting of stigma,style, and ovary.

Pollen Grains: The frameworks that save the immature masculine gametophytes.

Pollen Tube: The pollen tube acts as a conduit to move sperm cells from the pollen grain, which has actually landed on the stigma, come the ovules at the base of the pistil. The pollen pipe germinates from the pollen grain and also grows the entire length v the stigma, style and also ovules to with the eggs. Pollination: The placement of pollen top top the stigma the a carpel through wind oranimal carriers, a prerequisite come fertilization.

Primary (Apical) Meristems: Meristem is a kind of embryonic organization in tree consisting of unspecialized, youthful cells called meristematic cells and also found in areas of the plant wheregrowth occurs. The apical meristem is located just behind the root cap of root tips and also at the advice of shoots.

Procambium: A primary meristem that roots and also shoots that forms the vascular tissue.

Protoderm: The outermost main meristem, which offers rise come the epidermis of roots and shoots.

Seed: one adaptation for terrestrial plants consisting of an embryo packaged together with a keep of food within a resistant coat.

Sepal: A whorl the modified pipeline in angiosperms the encloses and protects the flower bud before it opens.

Sporophyte: The multicellular diploid kind in tree undergoing alternation of generations that outcomes from a union the gametes and that meiotically produces haploid spores that prosper into the gametophyte generation.

Stamen: The pollen-producing male reproductive body organ of a flower, consist of of one anther and also filament.
