ch 23 summary (Reproduction in Plants)
lesson3
A pollen tube is an extension
triploid
exine
Double fertilization occurs only in anthophytes.
Specialized cells in the anther undergo meiosis and form microspores.
Endosperm
The nuclei in the center are called polar nucle
seed coat.
Anthophytes have flowers
Simple fleshy fruits
Dispersal of seeds
Aggregate fruits
Dry fruits
Multiple fruits
germination, radicle, hypocotyl
eudicot, monocot
cotyledons
lesson 2
stamens which are the male reproductive organs. ( filament and an anther)
pistil: female reproductive organ (a stigma, a style, and an ovary)
.
peduncle attach the sepals and petals
Petals: can attract animals to pollinate the flower.
Flowers that have sepals, petals, stamens, and one or more pistils are called complete flowers.
Sepals protect the flower
Flowers that are missing one or more of these organs are called incomplete flowers.
Flowers that have both stamens and pistils are called perfect flowers
Flowers that have both stamens and pistils are called perfect flowers
When the petal number of a flower is a multiple of four or five the plant usually is a eudicot
Monocots usually have flower organs in multiples of three.
Self-pollinating, Cross-pollinated, Pollinated by animals, Pollinated by the wind
Photoperiodism. The range of hours is known as a plant’s critical period.
short-day plants, long-day plants, intermediate-day plants, and day-neutral plants
lesson 1
Vegetative reproduction: easy, fastest, one parent
horizontal stems
tissue culture
Alternation of generations, one generation is a diploid (2n) sporophyte. and the other is a haploid (n) gametophyte
moss reproduction: protonema
Sperm exhibit chemotaxis
fern reproduction: prothallus
Heterosporous: two types of spores
The opening of a female cone’s ovule is called the micropyle
