Chapter 30 Plant Reproduction
I.
________________________________________-Alternate between a diploid
sporophyte generation and a haploid gametophyte generation
a. Sporophyte produces ______________________
b. Gametophyte produces __________________________ (egg and sperm)
II.
Mosses
a. Gametophyte produces antheridium (sperm) and archegonium (egg)
b. Sperm breaks out of antheridium an swims through water to egg
c. Fertilization produces zygote
d. Sporophyte stalk grows to form __________________________________
e. Capsule splilts and releases spores into the air
f. Spores germinate and produce new gametophyte
III.
Ferns
a. Sperm releases by antheridium and swims to egg
b. Fertilization produces zygote
c. Embryo develops into sporophyte
d. Gametophyte dies and __________________________ develop
e. ____________________, clusters of sporangia, develop on underside of fronds
f. Spores released into air and New gametophyte develops
IV.
Parts of a Flower
a. __________________________– holds flower to stem
b. _________________________ – leaflets around the base of flower
c. _______________________ - colored part of flower (monocot 3, dicot 4 or 5)
d. ________________________-male reproductive structures
i. Anther: produces ________________________
ii. Filament
e. Carpel ___________________________-female reproductive structures
i. ____________________________– sticky top for catching pollen
ii. ______________________– pollen tube forms here
iii. Ovary – develops ________________________
f. Reproduction
i. __________________-Pollen from the anther are transferred to the stigma
ii. A pollen tube grows down into the style until it reaches the eggs inside the
ovule (inside ovary)
iii. Fertilization takes place and flower parts fall away
iv. Ovary becomes _______________________________
v. ___________________________develops into the seed.
V.
Pollination – transfer of __________________ (sperm cells) from anther to stigma
a. ___________________________ – pollen transfer from male part of plant to
female part of ______________________________
b. ____________________________ – pollen transfer from male part of one plant
to female part of another plant
VI.
Floral Structure
a. Complete Vs Incomplete Flower
i. Complete – ______________ male and female parts
ii. ___________________________ – either male or female parts
