Mrs. Nazario's class

Unit 4 Molecular Genetics 1

TermDefinition
Anther The upper portion of a stamen, which contains pollen grains
Cross-pollination The transfer of pollen from the anther of one flower to the stigma of another
Egg cell A female reproductive cell in a plant or animal
Embryo The undeveloped stage of a plant or animal. Examples: a plant that has not germinated; a baby chick that has not hatched
Fertilization The union of a male reproductive cell and a female reproductive cell to form a cell that will develop into a new individual
Filament The stalk of a stamen
Genetics The science of heredity
Germination Starting to grow or develop; sprouting
Ovary The enlarged lower part of a pistil and is the reproductive organ that produces egg cells. It encloses the ovules or young seeds
Ovule Part of a plant that develops into a seed, found in ovary of a flower
Pistil The entire female part of a flower
Pollen A powdery grain on the stamen that contains a sperm cell
Receptacle The stalk which holds a flower
Reproduction The process by which cell produce new cells like themselves, or by which an organism produces offspring
Self-pollination The transfer of pollen from the anther of a flower to the stigma of the same flower
Sepal One of the leaflike parts which make up the calyx of a flower
Sperm cell A male reproductive cell in a plant or animal
Stamen The male part of the flower generally composed of an anther and filament
Stigma The top of the pistil of a flower
Style A part of the pistil of a flower that extends from the ovaries to the stigma
Chromosome Rod-shaped parts of a cell that carry the genes (the hereditary material)
Gene The unit of DNA which carries inherited traits
Meiosis Cell division which takes place in the reproductive cells and which produce new cells with half the number of chromosomes
Mitosis Cell division whereby new cells have the same number of chromosomes as the parent. Example: Cell division for repair
Nucleus The part of a cell that contains the DNA molecule and controls cell activities
