The Parts Of A Flower

Fire is not a pollinator because it does not have the ability to transfer pollen from one plant to another, which is essential for pollination. Pollinators are typically living organisms such as insects, birds, bats, and even wind, which carry pollen grains and facilitate the fertilization of plants. Fire, on the other hand, is a destructive force that can harm or destroy plants, rather than aiding in their reproduction through pollination.

The arrow labelled E is pointing to the anther. The anther is the part of the flower's stamen that produces and holds the pollen. It is typically located at the top of the filament, which is the stalk-like structure that supports the anther.

Pollen grains contain the male sex cells. These grains are produced in the anthers of flowers and are responsible for the fertilization of the ovules. Once the pollen grains are transferred to the stigma of a flower, they germinate and grow a tube that allows them to reach the ovary and fertilize the ovules. Therefore, the correct answer is "pollen".

The ovule is the correct answer because it is the structure in the flower that contains the female reproductive cells, also known as the eggs or ova. The ovule is located within the ovary, which is part of the female reproductive system in plants. It plays a crucial role in fertilization and the production of seeds. The anther, on the other hand, is the male reproductive structure that produces pollen, which contains the male sex cells or sperm.

The filament is the part of the flower that holds up the anther. It is a slender, thread-like structure that supports the anther, which is the part of the flower where pollen is produced. The filament plays a crucial role in the reproductive process of the flower by ensuring that the anther is positioned correctly for pollination to occur.

The female part of the flower is called the carpel or pistil. The pistil is the reproductive organ of the flower that contains the ovary, style, and stigma. It is responsible for receiving pollen and facilitating fertilization. The sepal is the outermost part of the flower that protects the developing bud, while the stamen is the male reproductive organ that produces pollen.

The stamen, which is the male reproductive organ of a flower, is composed of two main parts: the filament (E) and the anther (F). The filament is a long, slender stalk that supports the anther, which is the part that produces and releases pollen. Together, the filament and anther play a crucial role in the process of pollination and fertilization in plants.

Fertilisation takes place in the part labelled "H" because in the context of reproduction, fertilisation refers to the fusion of a sperm cell with an egg cell to form a zygote. In human anatomy, fertilisation occurs in the fallopian tubes, which are represented by the letter "H" in the given options. The fallopian tubes are the site where the egg is released from the ovary and where it can be fertilised by a sperm cell.

After pollination, the pollen must travel down the style to get to the ovary. The style is a long, slender tube-like structure that connects the stigma (part of the female reproductive organ) to the ovary. It provides a pathway for the pollen to reach the ovary, where fertilization can occur. The style also plays a role in selecting compatible pollen for fertilization and providing support for the stigma.

After fertilization, the ovule undergoes a process called seed development. The fertilized ovule matures and transforms into a seed. The seed contains all the necessary components for the development of a new plant, including the embryo, endosperm, and protective seed coat. This transformation is essential for the plant's reproductive cycle as the seed serves as a means of dispersal and survival for the plant species.

The anther is the part of a flower that produces pollen. It is located at the top of the stamen, which is the male reproductive organ of the flower. The anther contains sacs called pollen sacs, which produce and release pollen grains. These pollen grains are then transferred to the stigma, the female reproductive organ of the flower, for fertilization to occur. Therefore, the anther is responsible for the production of pollen.

The sepal is a part of the flower that protects the developing flower bud. It is usually green and leaf-like in appearance and is located at the base of the flower. The sepal acts as a protective covering for the delicate petals and reproductive structures inside the bud.

The arrow labelled G is pointing to the ovule. The ovule is the female reproductive structure in plants that contains the egg cell. It is located within the ovary, which is the swollen base of the pistil. The ovule is responsible for the production of seeds after fertilization occurs.

During fertilization, the pollen, which contains the male gametes, fuses with the ovule. The ovule is the female reproductive structure found in the ovary of a flower. It contains the egg cell, which is fertilized by the pollen to form a zygote. This fertilized ovule then develops into a seed. Therefore, the correct answer is ovule.

After fertilization, the ovary undergoes a process called fruit development. This process involves the transformation of the ovary wall into a fruit. The fruit protects the developing seeds and aids in their dispersal. Therefore, the correct answer is fruit.
