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
