PPT-Plant transport: Xylem and Phloem

Chapter 4 pp 47 54 Lecture Outline Evolution of vascular tissue The xylem transports water and nutrients The phloem transports sugars and other organic compounds Xylem and phloem structure and function. Roots are used to . anchor the plant in the soil, to absorb minerals and water, conduct minerals and water and store food. . Root Tip Regions. . Regions. Function. Root Cap. Protect the apical meristem. Plants. Plant: . terrestrial (mostly), multicellular, photoautotrophic, eukaryote, true tissues and organs. Plant Structure .

STEP 1: Food and water enters phloem of the stem through diffusion and osmosis. . STEP 2: Water from xylem is transferred to the phloem to help break down/dissolve food in the phloem. The water pressure is kept at low. . suspension-feeder: . there are rows of projections called . lamellae . on the bill.. “…when the mouth is closed, the large upper bill completely covers the lower …and when the mouth is slightly ajar, the adjacent lamellae of the upper and lower bills can act together as a sieve.” They must interdigitate. The tongue (hydrostat, blood) powers this filter via . Types of stems. Either woody or nonwoody. Generally, adapted to support leaves; also transport materials and provide storage. . -stolons – grow along soil surface and produce new plants (strawberry). Types of Plant Systems | Plant Transport . |. . Plant Growth & Reproduction | Plant Response. Learning Objectives. Understand how the different types of plant systems interact. Explain transport of water, minerals, and carbohydrates in plants. Biology Department. Plant Tissues. Tissues can be classified into . :. Meristematic. tissues. . Permanent . tissues. I . . Meristematic. . tissues. They are usually called meristems. . They . are young tissues of the embryo or the mature plant which . AICE Biology 2017 . Introduction. Plants use photosynthesis to convert light energy to chemical energy . Simple organic substances, such as CO2, H2O and ions are used in their raw form to produce glucose and other carbohydrates.. Animals grow throughout the whole organism. many regions & tissues at different rates. Growth in Plants . Specific regions of growth: . meristems. stem cells: perpetually embryonic tissue. regenerate new cells. 2006-2007 Plant Anatomy Basic plant anatomy 1 root root tip root hairs Roots Roots anchor plant in soil, absorb minerals & water, & store food fibrous roots (1) mat of thin roots that spread out root. root tip. root hairs.
