Chapter 9 - Flowers and Reproduction
Sexual Reproduction
Flower Structure
composed of sepals, petals, stamens, carpels, and ovules
Gametophytes
microgametophyte
contains up to three cells, present in the pollen tube
megagametophyte
contains 8 nuclei, and a seven cells
The plant life cycle
unlike animals, second gametes do not die off, they find a second egg
Fertilization
fusion of the sperm to the egg
Embryo and seed development
seed develops apical meristem, hypocotyl, radicle, and suspensor inside the embryo, seed is hardened after formation and then dehydrated
Fruit Development
contains exocarp, mesocarp, and endocarp
Asexual Reproduction
fragmentation is the main mode of asexual reproduction with budding being the second

Flower Structure and Cross Polination
monoecious and dioecious species
differentiated by weather flowers contain both sets of reproductive organs or not
animal - pollinated flowers
flowers shape, scent, and color themselves to be highly findable by animals, often offering nutrition
stigma and pollen incompability
insurance from the plant that it does not cross pollinate, inhibited by chemicals
wind - pollinated flowers
use wind to spread pollen, emit pollen in mass quantities
stamen and style maturation times
pollen is released at different times than from when the eggs are ready
ovary position
flowers are designed to hide away nutritious ovules from pollinating animals, usually done by elongating the tube
Cross - pollination
receiving pollen from another plant
Inflourescence and pollination
brighter colors allow for selective pollinators and a much higher chance of pollination with less risk associated with producing larger flowers
Fruit types and seed dispersal
True fruits and accessory fruits
made to be eaten by animals - group contains simple, aggregate, and multiple fruits
