Explanation of Terms

Angiosperm- Plant that produces seeds which are enclosed in some type of fruit; another name is Anthophyta (UC-Clermont Biology 2014)

Cotyledon- Food source for a zygote growing within a seed (Campbell et. al 2008)

Dicot- A plant which possesses, among other things: 2 cotyledons; flower parts in 2, 4, or 5; vascular tissue bundles arranged in a ring in the stem; and one main taproot (UC-Clermont Biology 2014).

Dicotyledon- A plant that has 2 cotyledons (Calflora 2014)

Gametophyte- The 1n generation of a plant; produces gametes through mitosis (Campbell et. al 2008)

Meiosis- A special type of cell division in which 1, 2n-cell produces 4, 1n-cells that are each genetically unique; the 4, 1n daughter cells are called gametes (Campbell et. al 2008)

Mitosis- The most common type of cell division, in which 1, 2n-cell replicates its DNA and chromosomes and divides into 2, 2n-cells which are identical (Campbell et. al 2008)

Phloem- A type of plant vascular tissue which transports sugars and hormones in the plant; it is living at functional maturity (UC-Clermont Biology 2014, Campbell et. al 2008).

Pollen- Male gametophyte of a plant; formed when cells in the anthers undergo meiosis (UC-Clermont Biology 2014).

Seed- An embryonic plant; it contains the developing diploid plant as well as a food source (the cotyledons) (Campbell et. al 2008).

Xylem- The second type of plant vascular tissue; it transports water and minerals up from the ground and is dead at functional maturity (UC-Clermont Biology 2014, Campbell et. al 2008).
