Unit 12: Plants
Parts of the plant: Roots, Stems, Leaves, Vascular tissue, Flowers, seeds
Unit 12: Plants
Xylem: water and nutrients are transported from roots to leaves
Phloem: carbohydrates are transported from the site of Photosynthesis to the rest of the plants
Reproductive structures: pistil (stigma, style, ovule, ovary), stamen (anther and filament), petals, and sepals
Fertilization/Germination: dormancy, n or 2n, sperm, egg, zygote
Plant Hormones: Auxins (elongation), cytokinins (mitosis/cell division), gibberellins cell elongation), ethylene (ripen fruits)
Tropism: phototropism, photoperiodism, gravitropism, thigmotropism, nastic movement
Seed dispersal types: gravity, wind, water, animal
Gymnosperm: seed-producing plants that includes conifers, cycads, Ginkgo, and Gnetales. The term "gymnosperm" comes from the Greek word gymnospermos (γυμνόσπερμος), meaning "naked seeds", after the unenclosed condition of their seeds
Angiosperm: the most diverse group of land plants. Angiosperms are seed-producing plants and can be distinguished from the gymnosperms by derived characteristics. These characteristics include flowers, endosperm within the seeds, and the production of fruits that contain the seeds and more commonly referred to as flowering plants.
Monocotyledon: 1 cotyledon, Flower parts in multiples of 3, Stem vacular bundles scattered
Dicotyledon: 2 cotyledons, Flower parts in multiples of 4 or 5, Stem vascular bundles in a ring
