Life Part 2

Reproduction in Plants & Animals STEMScopes

TermDefinition
anther the part of a flower that contains the pollen; located at the end of the stamen
behavior what a plant or animal does to increase the probability of finding a mate (examples: plumage, vocalization)
ovary reproductive organ that produces egg cells
petals the colorful, leaflike structures that encircle the center part of a flower
pistil the structure of the flower that contains the stigma, style, & ovary
pollen fine to coarse particles that spread from flowers and seeds of plants
pollination the process of fertilizing flowers by transferring pollen from the male to female parts
reproduction the process by which organisms produce offspring, or young; allows organisms to pass their traits, or characteristics, through genetic material, or DNA
specialized having characteristics that allow specific functions to be performed
stamen the structure of the flower that contains the anther and filament
sexual reproduction requires a male and female; each contribute half of their DNA; female contributes her DNA in an egg; the male contributes his DNA in sperm
fertilization occurs when the male and female sex cells unite to form a seed
sepals modified leaves that encase the developing flower; sterile parts of the flower and are usually green or leaflike
stigma has an adhesive area that allows the pollen from the stamen to stick to the pistil
seed dispersal plants have evolved ways of spreading seeds over larger areas to minimize competition between parent and offspring (ex: wind, water, animals)
asexual reproduction bacteria, fungi, and nonflowering plants reproduce asexually...only needing ONE parent; eukaryotic organisms reproduce asexually in several ways: mushrooms form spores; hydra reproduce by budding;
eukaryotic describes an organism that has cells with a nucleus and other membrane-bound organelles
propagation plants can reproduce asexually through vegetative propagation ("eye" or budds from potatoes)
