Chapter 23 - Mader Biology
Flowers - The reproductive structure in plants
Double Fertilization - One sperm unites with an egg, forming a diploid zygote, and the other
unites with polar nuclei, forming a triploid endosperm nucleus.
Eudicotyledones (Eudicots) - -Two cotyledons
-Flowering parts in four of fives or multiples of four or five
-Pollen grain with three pores
-woody or herbaceous
-usually net venation
-vascular bundles in a ring
-taproot system
Alteration of generations - The alteration of two or more different forms in the life cycle of a plant
or animal.
Angiosperms - A flowering plant which forms seeds inside a protective chamber called an ovary.
Anther - pollen-producing structure located at the tip of a flower's stamen
Antheridia - produces sperm
Apical Growth - primary growth -- controls the growth height
Archegonia - produces eggs
, Bryophytes - nonvascular plants
Carboniferous Period - period of time from 350 to 290 million years ago - resulted in coal deposits
Carpel - The female reproductive organ of a flower, consisting of the stigma, style, and ovary.
Charophytes - a division of freshwater green algae
Chlorophylls - main pigments that help plants absorb light energy
Complete - having all four parts (sepals, petals, stamens, and carpels)
Composite - Appears to be a single flower but consists of a group of tiny flowers
Cones - Cells that respond to color
Conifers - cone bearing trees
Cotyledons - seed leaves
Cuticle - The waxy, waterproof layer that covers the leaves and stems of most plants.
Cycads - Short, thick-stemmed plants with a crown of large fern-like or palm-like leaves
Dioecious - a single plant produces either male or female reproductive structures, but not both
Endosperm - food-rich tissue that nourishes a seedling as it grows
