|
|
small pollen grain is a multi-cellular
|
male gametophyte
|
|
|
number of cells in a pollen grain
|
2
|
|
|
Ovules produce
|
4 megaspores only 1 will survive which will form the female gamete
|
|
|
female spore divides -- times
|
3
|
|
|
number of cells in a female game
|
8
|
|
|
8 cells in a female gametophyte and their function
|
1 egg- forms the zygote
2 polar nuclei- form the endosperm 2 synergies- signal the gamete were to grow to 3 antipodal-that have no known function |
|
|
a small pore in the integuments of the ovule
|
microphyte
|
|
|
seed leaves
|
cotyledons
|
|
|
an endosperms is
|
3n
|
|
|
endosperm is 3n so
|
it won't compete
|
|
|
In double fertilization
|
·
One sperm fuses with the egg the other fuses with the 2 polar nuclei making a 3n endosperm (works as a food supply) |
|
|
the endosperm functions as
|
food supply
|
|
|
• The interanther will produce a
|
microsporophyte
|
|
|
microsporophyte under goes ___ to produce _______
|
meosis
4 microspores |
|
|
microspore will go under mitosis __ times to produce ____
|
one time to
produce pollen grains |
|
|
pollen grains have _ cells
|
2
|
|
|
in the ovule the megasorocyte will undergo ______ to produce ____which undergoes mitosis__ times
|
meiosis
4 megaspores (only 1 survives) 3 times |
|
|
a ,female gametophyte has
|
8 cells
|
|
|
eight cells of the female gametophyte
|
1 Egg- that becomes the zygote
2 polar nuclei- fuse to make the endosperm 2 synergids- are releasing chemical signals 3 antipodal- No known use |
|
|
2 reason plants try to avoid self fetilization
|
because self fertilizations will not allow plants to diversify
without diversification the plants are less likely to have good genes |
|
|
3 ways plants try to avoid self fertilization
|
In
dioecous plants flowers are unisexual Some grow so that the sigma and anthers are at different levels Some plant's anthers and ovaries will develop at different times |
|
|
After Double fertilization ovule develops into the ____ ovary develops into ____
|
into the seed
into the fruit |
|
|
Fruits are classified by the number of
|
ovaries
|
|
|
After Double fertilization ____ develops into the seed develops ___ into the fruit
|
ovule
ovary |
|
|
three classification of seeds
|
Simple--1--cherries
Aggregated--multiple--raspberry Multiple--has multiple flowers--pineapple |
|
|
Some seeds will enter a dormancy phase due to
|
Flood
fire digestion cold |
|
|
Germination begins with the uptake of
|
water
|
|
|
Asexual reproduction (3 types)
|
1.) cloning
2. ) meristem tissues can be used for asexual reproductions 3.) Apoxmix that have their male and female parts together so their seed dispersal is based on the wind |
|
|
the cloning of aspen trees
|
products of different shoots
This is good because if the tree is isolate it can reproduce and if the tree is well adapted for survival it is spreading those genes |
