Good Morning! Monday, 12/7 As you come in: Take out a blank piece of paper and begin brainstorming what your data table is going to look like. It must include these items: 1.Title (includes MV & RV) 2.Labels for rows (MV) & columns (RV) 3.Multiple pieces of data 4.Units on data 5.Observations section

DATA TABLE DATA TABLE EXAMPLES:

 Create your data table on a blank piece of paper.  Everyone in your group needs to have their own data table!  Staple your data table to your lab set up (salmon sheet).  Collect your data & make observations.

How does water flow through a plant?  Transpiration Lab

PLANT ANATOMY (plant structure)  Shoot system  Above ground  Root system  Under ground

PLANT ANATOMY  Root system (label) PURPOSE  Anchors the plant in the soil  Absorbs water & nutrients  Conducts water & nutrients  Food storage

 Shoot system (label) PURPOSE  Elevates the plant above the ground  Conducts food & water  Photosynthesis  Reproduction & dispersal PLANT ANATOMY

PLANT TISSUES  Every part of a plant is made up of 3 different types of tissue: 1. Dermal Tissue (label)  Protection  Epi dermis = skin 2. Ground Tissue (label)  Synthesis of sugars  Storage  Support 3. Vascular Tissue (label)  Transport (like veins transport blood)  Support

 Absorb water & nutrients  Root Hairs (label)  Tubular extensions  Increases surface area of root  Aids in water & nutrient absorption ROOTS (dermal tissue)

ROOTS (ground tissue)  Cortex provides support and stores starch & sugars epidermis cortex vascular Hey! I yam what I yam, man! You’re not a yam, you’re a sweetpotato!

STEMS (label)  Usually above ground  Supports leaves and fruits  Conducts water and nutrients throughout the plant epidermis pith cortex Vascular bundles

STEM types  Herbaceous vs. Woody stems

STEM (vascular tissue) Phloem transports sugar Xylem: tiny tubes that act like straws to transport water and minerals

WOODY STEM  Annual rings : xylem formed during one growing season  One ring = one year

History of the tree: annual rings 1489: Tree is planted by Native American 1492: Columbus lands in the Americas 1620: Pilgrims land in Plymouth, Mass. 1776: Declaration of US independence 1861: Start of Civil War 1969: Man lands on Moon 1917 & 1945: Tree Survives two World Wars 1971: Birth Year of the IDIOT who cut down this tree!!! Dendrochronology : tree time-keeping

 How water & minerals moves from the ground to the top of a plant  Plants loose water out of their leaves  Which pulls water up from the stem  Which pulls water up from the roots  Which absorbs water from the ground TRANSPIRATION (label)
