E N D
Mon April 21 To Do Today • Check seeds - draw, label and water • Complete Plant dissetion Activity Warm Up- • What does the term non-vascular mean? • How do non vascular plants get nutrients? Homework: progress reports Friday
Seed Check • Examine your seeds - what can you label? Draw seeds (detail) and put into soil –being careful to no damage roots
Tues April 22 To Do Today • Check seeds - draw, label and water • Foldable notes on angiosperms • Complete Plant dissetion Activity Warm Up- What is the name of The male part of flower? What parts does it contain? Homework: progress reports Friday
ANGIOSPERMS: • Have flowers • Fruits contain seeds with covering • Angiosperms are divided into two groups: Monocots & Dicots.
Monocots • Parallel venation in leaves • Flower parts in multiples of 3 • Vascular tissue scattered in cross section of stem 24
Dicots • Net venation in leaves • Flower parts in multiples of 4 or 5 • Vascular tissue in rings in cross section of stem 25
April 24&25 To Do Today • Check seeds - draw, label and water • Foldable notes on angiosperms • Complete Plant dissection Activity • Review video on plants(handout) • Leaf Activity Warm Up- + reflection Homework:
Is this a monocot or a dicot? Why? DICOT 2 leaves
Non-essential parts- Not needed for sexual reproduction • Receptacle: Base of the flower • Sepals: smaller leaves protecting flower located at the base • Petals: Colored tissue covering the internal sexual organs • WHY ARE THEY SO BRIGHTLY COLORED???
Pollination • Flower parts fall off and each Ovary grows into a fruit which contains seeds. • This only happens for plants that produce fruit
To attract the pollinators….birds, bees, butterflies. • The goal of the plant is to get any pollinator to knock the pollen off of the stamen and have it land at the stigma. • Wind, rain or brushing up against a flower could also achieve this goal.
Seed dispersal • Wind • Water • Animals
Wed/Thurs/Fri • To Do Today • Review flowers • Finish notes on flowers in foldable • Coloring of leaves • Warm Up – reflection • 1. What are the 2categories of seed producing vascular plants? • 2. What is the function of the ovary of a flower? • Homework: none
1. 2.
Other types of flowers • Some flowers, such as grasses, do not have brightly colored petals and nectar to attract insects. • These flowers are pollinated by the wind.
Vascular System • Xylem tissue carries water and minerals upward from the roots • Phloem tissue carries sugars made by photosynthesis from the leaves to where they will be stored or used • Sap is the fluid carried inside the xylem or phloem Copy onto leaf anatomy handout 12

Some drinks from plants • Birch sap can also be used as an ingredient in food or drinks, such as birch beer or wintergreen flavored candy • Maple syrup is a syrup usually made from the xylem sap of sugar maple, red maple, or black maple trees, although it can also be made from other maple species. In cold climates, these trees store starch in their trunks and roots before the winter; the starch is then converted to sugar that rises in the sap in the spring. Maple trees can be tapped by boring holes into their trunks and collecting the exuded sap. The sap is processed by heating to evaporate much of the water, leaving the concentrated syrup • Root beer is a carbonated, sweetened beverage, originally made using the root of a sassafras plant (or the bark of a sassafras tree) as the primary flavor.
