| Question |
Answer |
| female reproductive part of a flower |
pistil |
| male reproductive part of a flower |
stamen |
| stem-like structure of a stamen |
filament |
| top portion of a stamen |
anther |
| sticky top of a pistil |
stigma |
| the stem-like part of a pistil |
style |
| the bottom of a pistil |
ovary |
| What is the function of the ovary? |
produce eggs (ovules) |
| what is a perfect flower? |
one with both male and female parts |
| What is an imperfect flower? |
one without both male and female parts |
| process of pollen from an anther contacting the stigma of a pistil |
pollination |
| if the pollen is transferred to a stigma of the same plant |
self-pollination |
| if the pollen is transferred to a stigma of a different plant |
cross-pollination |
| union of a sperm nucleus and an egg nucleus |
fertilization |
| What must happen after pollination before fertilization can occur? |
Sperm nuclei must travel down the pollen tubes and into the ovary |
| a structure that developed from the ovary of a flower; it protects seeds and can assist in dispersal |
fruit |
| How do flowers promote their own pollination? |
bright petal colors, unique aromas |
| What will a fertilized egg (ovule) develop into? |
a seed |
| reproduction with one parent, in which the offspring are identical to the parent |
asexual reproduction |
| reproduction with a male and female parent in which the offspring are different from (a genetic recombinaton of) the two parents |
sexual reproduction |
| examples of asexual reproduction |
budding, runners, cuttings, bulbs, binary fission |
| when amoeba or other simple organisms reproduce asexaully by splitting in two (cell division) it is known as |
binary fission |
| type of asexual reproduction in which outgrowths on an organism eventually break off and become self-sufficient |
budding |
| an advantage of asexual reproduction |
convenient - only one parent |
| a disadvantage of asexual reproduction |
cannot improve the quality of the species |
| an advantage of sexual reproduction |
increases diversity through genetic recombination |
| a disadvantage of sexual reproduction |
requires union of male and female (is less convenient- have to wait for pollination or other actions) |
