| 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)
🗑
|
||||
| process of pollen from an anther contacting the stigma of a pistil | 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, patterns on petals, open funnel-like shape
🗑
|
||||
| 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 sex cells (sperm and egg cells)- offspring is not identical to either parent | sexual reproduction
🗑
|
||||
| examples of asexual reproduction | budding (Hydra), binary fission (amoeba, bacteria, etc), regeneration (worms, etc)
🗑
|
||||
| advantages of asexual reproduction | convenient - only one parent; takes less energy/investment
🗑
|
||||
| disadvantages of asexual reproduction | cannot improve the quality of the species - always identical; more difficult to adapt to changing environment
🗑
|
||||
| examples of sexual reproduction | pollination and fertilization of flowers to produce seeds; mating of animals, even hermaphrodites
🗑
|
||||
| what is a hermaphrodite? | an animal with both male and female parts
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
