Plant Systems (Structures, Functions) & Adaptations Fold your sheet in half. Reproductive System Root System Shoot System Flower Cut flaps by cutting the FIRST layer only. Stem Label the systems and draw the arrows. Roots Label the parts on the front. Leaf Fill in your foldable with the notes provided. Structure will go on the left side and Function will go on the right. Adaptations to the environment will go on the back. Flowers reproductive organ of a plant Structure Function Anther - produces pollen Pollen - haploid male gametes (sex cells) Stigma - Sticky top of style where Style pollen lands. - Transports pollen to the ovary. Ovary (Fruit) - Female organ which produces female gametes. A ripened ovary is the fruit, the seed is the embryo. Adaptation to Environment 1. Bright colors and odorous nectar to attract pollinators. 2. Development of Fruit for seed dispersal. Leavesphotosynthetic organ of a plant Structure Cuticle Function - Prevents water loss Mesophyll - Photosynthesis Veins - Xylem & Phloem Stomata - Lets CO2 in and O2 and H2O out Adaptation to Environment 1. Thick cuticle in dry climates. 2. Few stomata to prevent water loss. 3. Thick stem to store water (cactus) Stems Structure Xylem Function - Vascular tissue (tubes) that carry water from the roots to the leaves for photosynthesis and to other parts of the plant. Phloem - Vascular tissue (tubes) that carry glucose (food) from the leaves to other parts of the plant. Adaptation to the Environment 1.Stiff cell walls for trunks and branches. 2.Dead Xylem becomes the wood on the inside of tree trunks. 3. Can be modified to store food. Ex: Tubers (potatoes) and Bulbs (garlic, onions) Roots Structure Function Epidermis -protection and & root cap absorption of water and minerals. Root hairs -increase surface area for absorption of water & nutrients Root tips - tip of root that is growing into the (apical soil (area of meristem) mitosis). Adaptations to the Environment 1. Can be modified to store starch and sugar. (Carrots, Beets, Turnips) 2. In dry climates taproots form & can be extremely long to reach & store water. 3. Fibrous roots are good for preventing erosion and getting surface water due to being a thin and branching root system. 4. Capillary Action - force that allows the roots and the stem to absorb the water up in to themselves, against the force of gravity
