ANGIOSPERMS: Have flowers Fruits contain seeds with covering
Angiosperms are divided into two groups: Monocots & Dicots.

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
![Page 17: Mon April 21](https://reader036.fdocuments.in/reader036/viewer/2022062310/56816417550346895dd5cd29/html5/thumbnails/17.jpg)
17
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.

Wed/Thurs/Fri To Do Today
• Review flowers • Finish notes on flowers
in foldable• Coloring of leavesWarm Up – reflection
1. What are the 2 categories of seed producing vascular plants?2. What is the function of the ovary of a flower?Homework: none

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 SystemXylem 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

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Root beer is a carbonated, sweetened beverage, originally made using the root of a sassafras plant (or the bark of a sassafras tree) as the primary flavor.

Why We Can’t do Without Plants!
Produce oxygen for the atmosphereProduce lumber for buildingProvide homes and food for many organisms
Prevent erosionUsed for food
