Here, George describes the parts of the plant.
|
|
|
|
 | |  |
| Plants have flowers, which are their reproductive organs. The sepal protects the unopened flower. Flowers usually have petals that are brightly colored, usually insect pollinated ones. | |
 | |  |
|
 |
| | |
| Cool. They also have a stamen, which is an anther attached to a filament. This si the male part of the flower. This produces male gametes, which is the pollen. | |
| | |
|
|
|
|
Wind pollinated plants look different to insect pollinated ones because they are adapted to catch pollen floating in the wind.
|
|
|
|
| | |
| The stigma collects pollen, and is the top of the female part of the flower. Wind and insect pollinated flowers are adapted differently for that. | |
| | |
|
|
| | |
| Oh yeah! Some flowers have nectar to appeal to insects. | |
| | |
|
|
|
|
In wind pollinated plants, the stigma catches the pollen flying around. In insect pollinated plants, insects are responsible for the gametes coming together.
|
|
|
|
| | |
| So, in response to your letter, plants reproduce when the male and female gamete fuse, presuming it is sexual reproduction. This happens when the pollen grain travels down to the ovary in the plants. | |
