Unit 13 Review - Plants Instructions: Below is a chart of words and their definitions. You may use these for three things: 1. Make flashcards with the definitions and vocabulary 2. Cut out the boxes, shuffle them, spread them out face up, and match the definitions with the vocabulary words (you may wish to take a picture of them first so you can check your answers) 3. Cut out the boxes, shuffle them, spread them out face down, and play memory (you may wish to take a picture of them first so you can check your answers) Botany Meristem the scientific study of plants and their relationships Have a circulatory system Most plant No circulatory system and reproduce with spores EX: Moss areas of rapidly dividing cells Apical Meristem occurs at tips of roots/ shoots Lateral Meristem increases diameter of stems/ stalks Cuticle Monocot Cotyledon (sprout) waxy protective layer on the surface of the leaves, shoots, etc. contains a fat layer called cuticle for protection from drying out Carries mainly water with dissolved nutrients away from the roots. carries food, ex: sugars, made in the leaves to the roots. tissue that is not meristem, epidermal, vascular used for Photosynthesis, storage, and support One cotyledon (sprout) Dicot Cotyledon (sprout) Two Cotyledons (sprouts) Monocot Flowers and structures Flowers and structures in 3 parts Dicot Flowers and structures Flowers and structures in 4-5 parts Vascular Plants Non-vascular Plants Epidermis Xylem Phloem Ground Tissue Monocot leaves Veins in leaves are parallel Dicot leaves Veins in leaves are net/web-like Monocot vascular tissue Vascular tissue in bundles throughout ground tissue Vascular tissue arranged in a ring Dicot Vascular Tissue Root Cap Tap Root Fibrous root Adventitious Root Protects apical meristem cells underneath, as the cap is pushed through the dirt main root that is larger and grows faster than the branch roots all roots about the same size Blade roots that form on any plant part other than the roots Wide, flat part of leaf Simple Leaf blade is undivided Compound Leaf Blade is divided into leaflets Transpiration moisture is carried through plants from roots to stomata (small pores) on the underside of leaves, where it is released as vapor to the atmosphere Promotes cell growth in a specific direction. Makes cells on dark side of plant grow to push it towards the light regulate growth influence various developmental processes, including stem elongation, germination, dormancy, flowering, sex expression, and leaf and fruit development promotes cell division (cytokinesis), thus making plants bigger. Growth of new shoots Stimulates seed germination (sprouting) Auxin Gibberellins Cytokinins Ethylene Phototropism Gravitropism Thigmotropism Stamen Anther Filament Pistil Stigma Style Ovary Ovule Cross Pollination Only hormone found as a gas causes complex carbohydrates to break down into simple sugars, thus speeds up ripening growth toward a light source growth towards gravity or away from gravity. growth towards point of contact. Male reproductive organ with 2 parts: Anther and Filament Where meiosis occurs to produce pollen a stalk that supports the anther Female reproductive organ with 3 parts: stigma, style, and ovary receives the pollen from the anther Supports the stigma and the pollen grows a tube down through this Contains ovules and becomes the fruit after fertilization The unfertilized seeds Dicot roots Pollen is received from a different plant Taproot system Monocot roots Fibrous root system Stoma Openings on the underside of the leaf that allow gas exchange
