Indicator 6-2.1 - Summarize characteristics that all living things share. 6-2.2 - Recognize the hierarchical structure of the classification of organisms. 6-2.3 - Characteristics of Various Plants Question(s) of the Day 1. What is photosynthesis? Question(s) of the Day 1. What is photosynthesis? Photosynthesis: ____ + ____ + ____ = ____ & ____ Question(s) of the Day 1. What is photosynthesis? Photosynthesis: Carbon Dioxide + Water + Sun Light = Sugar & Oxygen PLANT KINGDOM Nonvascular Vascular Ex. Mosses Seed-producing Spore-producing Ex. Ferns Cone-bearing Flowering Monocot Mono = 1 Dicot Di = 2 Spore-producing Vascular Plants What are vascular plants? • The largest group in the Plant Kingdom. • Have a well-developed system for transporting water and food; so, they have roots, stems, and leaves. • Vascular plants have tube-like structures that provide support and help circulate water and food throughout the plant. Vascular Plants What are vascular plants? • Xylem transport water and minerals from the roots to the leaves. • Phloem transport food from the leaves to the rest of the plant. • Ex: Trees and shrubs with woody stems (hard/brown) that grow very tall and grasses, dandelions, and tomato plants with soft herbaceous (green) stems. Nonvascular Plants What are • They DO NOT have a wellnonvascular developed system for transporting plants? water and food; they DO NOT have true roots, stems, or leaves. • Get nutrients directly from the environment and distribute it from cell to cell. This results in very small plants. • Examples include mosses, liverworts, and hornworts. Spanish Moss Seed-Producing Plant • Reproduce through seeds they make. • Seeds contain the plant embryo (the beginnings of roots, stems, and leaves) and stored food (cotyledons) and are surrounded by a seed coat.. Stored Food Embryo Seed Coat • There are two major groups of seed-producing plants: flowering plants and cone-bearing plants. Spore-Producing Plant • • • • Produce spores for reproduction instead of seeds. Spores are much smaller than seeds (look like dust). Almost all flowerless plants produce with spores. Examples include mosses and ferns. Ferns Mosses Flowering Plants • Flowering plants differ from conifers because they grow their seeds inside an ovary, which is embedded in a flower. • Flowers then becomes a fruit containing the seeds. • Examples include most trees, shrubs, vines, flowers, fruits, vegetables, and legumes. Cone-Bearing Plants • Most cone-bearing plants are evergreen with needlelike leaves. • Conifers never have flowers but produce seeds in cones. • Examples include pine, spruce, juniper, redwood, and cedar trees. Monocot Plants • A seed with one food storage area. • Flowers have 3 petals or multiples of 3. • The leaves of monocots are long and slender with veins that are parallel to each other. • Examples include grass, corn, rice, lilies, and tulips. Dicot Plants • A seed with two food storage areas. • Flowers of dicots have either 4 or 5 petals or multiples of these numbers. • Leaves are usually wide with branching veins. • Examples include roses, dandelions, maple, and oak trees.
