There is homework tonight. Students are to read pages A20-A31 and answer 1-5 on A31.
Today we learned about gymnosperms and angiosperms. We learned that gymnosperm means naked seed. Some gymnosperms are conifers, ginkgo biloba, cycads and gnetophyes. These plants have male and female cones. Angiosperms are any plants that have enclosed seeds. These can include apple trees, and all other fruit trees, flowers, grains, cotton etc. Angiosperms are divided into two groups; monocots and dicots. Monocots have one cotelydon, flower petals in threes or multiples of three, leaf veins that are vertical and vascular bundles scattered throughout the plant. Dicots have two cotelydons, flower petals in multiples of four or five, leaf veins that branch out, and vascular bundles that are in a ring, not scattered.
Homework is due at the start of class.
