Answer:

1.Most flowers have four main parts: sepals, petals, stamens, and carpels. The stamens are the male part whereas the carpels are the female part of the flower. Most flowers are hermaphrodite where they contain both male and female parts. Others may contain one of the two parts and may be male or female.

2.No, pistillate flowers lack anther and a filament.

3.Ovary, in botany, enlarged basal portion of the pistil, the female organ of a flower. The ovary contains ovules, which develop into seeds upon fertilization. The ovary itself will mature into a fruit, either dry or fleshy, enclosing the seeds.

4.As mentioned, many flowers have both male (stamen) and female (pistil) parts. This enables a flower to create seeds and fruit all on its own that can then be pollinated with the help of insects, birds or other creatures.

5.An incomplete flower is defined as a flower missing any of its parts in its natural form, i. e. petals, sepals, stamens or pistils.

6.Complete flowers contain four flower parts: petals, sepals, stamen, and pistil. Incomplete flowers are missing one or more of these four parts. It is possible for a perfect flower to be incomplete, but it is not possible for an imperfect flower to be complete.

7.Plants may produce flowers that are perfect or imperfect. A flower with male and female parts is called a perfect flower. A flower that is missing male or female parts is an imper- fect flower. ... Imperfect flowers are always incomplete, but incomplete flowers may or may not be imperfect.

8.Complete flowers contain four flower parts: petals, sepals, stamen, and pistil. Incomplete flowers are missing one or more of these four parts. It is possible for a perfect flower to be incomplete, but it is not possible for an imperfect flower to be complete.

Answer:

1.Penducle: The stalk of a flower.

Receptacle: The part of a flower stalk where the parts of the flower are attached.

Sepal: The outer parts of the flower (often green and leaf-like) that enclose a developing bud.

Petal: The parts of a flower that are often conspicuously colored.

Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther.

Anther: The part of the stamen where pollen is produced.

Pistil: The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma. The mature ovary is a fruit, and the mature ovule is a seed.

Stigma: The part of the pistil where pollen germinates.

Ovary: The enlarged basal portion of the pistil where ovules are produced.

2.Yes

3.Yes

4.Flowers, such as roses or lilies, have both male and female parts called “perfects.” Some flowers, such as those found on cucumbers or melons, have all male or all female parts but not a combination of both. These types of flowers are called “imperfect.”

As with most living things, the male and female parts of a flower work together to reproduce.

5.An incomplete flower is defined as a flower missing any of its parts in its natural form, i.e. petals,sepals,stamens, or pistils.

6.Complete flowers contain four flower parts: petals, sepals, stamen, and pistil.

Incomplete flowers are missing one or more of these four parts. It is possible for a perfect flower to be incomplete, but it is not possible for an imperfect flower to be complete.
