Plants Overview Nonvascular Plants Hornwort Usually small plants
Everything transported by diffusion and osmosis Life Cycle of Nonvascular
Plants (MOSS) Vascular Plants (Seedless) Some early vascular plants only
reproduce with spores and not seeds Ferns are examples of these
Spores (how a fern reproduces) Life Cycle Vascular (seed) plants
Two types Gymnosperms Angiosperms
Monocots Dicots Gymnosperms Plants that make seeds that do not
develop into a fruit Usually bear pollen or seed cones Gymnosperm Life Cycle
Angiosperms Flowering Plants and trees More than 230,000 species and 300 families!!!
Monocots Seeds produce a singe cotyledon (seed leaf) Parallel veins
Flowers usually in multiples of 3s Ex. Grasses Dicots Flowering plants
produce 2 cotyledons (seed leaves) Leaf veins form a network Flower parts in multiples of 4 or 5
Plant transport Water and nutrients transfer through the xylem Red circles in the
middle Transpiration Water lost through the stomates Guard cells help to
regulate the loss of water Translocation Phloem moves sugar made in the leaves
or roots (source) to a storage place (sink) Process is called translocation Green cells
FLOWER POWER Why are angiosperms so successful and diverse? What are the structures of the flower? How are the structures best suited for their functions?
USE YOUR TEXTBOOK!!! Flowers 4 main parts
Petals (together make the corolla) Sepals (together make the calyx) Stamens (male parts; produce pollen)
Pistils (female parts) Stigma Style Ovary Fruits
We think of it as yummy, healthy food Botanist definition is ripened ovary of a flower Peas, eggplant, tomatoes, cucumber, squash, peppers are all really fruit
Simple Fruits Created from a single ripened ovary 2 Types Dry Fleshy
Aggregate Fruits Come from a single flower but multiple ovaries
developing in that flower Multiple Fruit Formed from several flowers of each
having an individual ovary Seeds Monocot vs. Dicot Questions to answer
1. How is a flower like a baboons butt? 2. How is plant reproduction similar to animal
reproduction?
