Chapter 9
Flower Structure and Cross Pollination
Cross Pollination
Pollination of a carpel by pollen from different individuals
Stamen and Style Maturation Times
Self Fertilization in flowers have both stamens and carpels
Stigma and Pollen Incompatibillity
Compatibility barriers inhibit self pollination
Monoecious and Dioecious Species
Latter organs are essential organs
Animal Pollinated Flowers
had dramatic impact on evolution of Flowering plants
Wind Pollinated Flowers
Pollination is aided by the growth pattern of a plant pollination
Ovary Position
Must be well protected
Great for protection
Burying the ovaries deep in the flower offer more protection
Sexual Reproduction
Flower Structure
Flowers are stems with leaf structures
Flower Stalk is a pedicel
Gametophytes
Microspores develop
Develop into
Microgametophytes
The plant life cycle
Very Simple
Diploid adults have sex organs, they produce haploid sex cells
Haploid Sex cells
Gametes
Fertilization
Sperm and Egg development involve plasmogamy and karyogamy
Embryo and Seed Development
Cells at an end of the suspensor continue to divide
Fruit Development
Ovule develops into a seed and ovary matures into a fruit
Inflorescences and Pollination
Reproductive success is measured in terms of number of healthy seeds
Large flowers has a large amount of ovules
Positioning is important
Asexual Reproduction
Angiosperms have numerous methods of asexual reproduction
Most common is fragmentation
Fruit Types and Seed Dispersal
True Fruits and Accessory Fruits
Pericarp refers to the tissues of fruit
Fusion of carpels also affects the nature of the fruit
Classification and Fruit Types
Many ways to classify a fruit
Simplest fruits come from the grass
