1. The aesthetic guarantee of a continued place within nature and the attraction of pollinators are two explanations as to how flowers benefit their plant.

2. The basic function of the petal is to attract insects and mamals to the flower for pollination; to a certain degree they also off a small amount of protection to the reproductive structures.

The petals are also called the inflorescence of the the flower.

In Dicotyledonous flowers the petals are protected when young by the calyx.

In Dicotyledonous plants the flowers either have petals in multiples of 4 or 5 (eg. 4, 8, 12 or 5, 10, 15 etc.).
In Monocotyledonous plants the flower have petals in multiples of 3 (eg. 3, 6, 9 etc.).

Some petals are brightly coloured and are pleasant for humans to look at.

Flowers that sometimes appear drab to humans are patterned in ways that are visible to animals and insects, but not us - they may contain pigments and patterns that are only visible in utraviolet light (which some insects can see).

Petals have no function in photosynthesis.

3. The anther is the part of the flower that holds the pollen. This and the filament both make up the stamen. Anther generally has four pollen sacs in a dithecous anther and in a monothecous anther like that of hibiscus there are 2 pollen sacs and each pollen sacs hold a microsporangium which produces pollen grains that how anther plays a main role in the development of pollen grains.

4. Part of the pistil holds the ovule(s) and is located above or below or at the point of connection with the base of the petals and sepals. The pistil may be made up of one carpel or of several fused carpels, and therefore the ovary can contain part of one carpel or parts of several fused carpels.

5. It is benefited because fruits are the means by which flowering plants disseminate seeds. Evolution has led plants to adopt certain basic mechanisms, seemingly without close regard to the tissues involved. No one terminology really fits the enormous variety that is found among plant fruits. Botanical terminology for fruits is inexact and will remain so.

6. It is made when a flower is pollinated, the fruit starts to form around it and may perform several purposes ), protecting it from harm, helping it to travel by air or water, drawing a herbivore which may carry the seed elsewhere after it has eaten the fruit.

7. It is sticky to best catch the pollen grains.

angiosperms is another word for flowering plants and they are divided into to cactegories
gynaecium is another word for carpel...the carpel is the female part of the flower, it is made up of the stigma, style, ovary and ovule....HOPE I HELPED :D

inflorescence

Beckmannia syzigachne


The inflorescences of spiklets that are stongly laterally compresses and stacked like pancakes in a secund arrangement is very characteristic of this species.
