In flowering plants, male and female gametes are produced in the anther and ovule, respectively. Male gametes are contained within pollen grains, which are released from the anthers at anthesis.
Which part of flower produces male and female gametes?
Answer: (c) In a flower, the parts that produce male and female gametes are anther and ovary respectively. Stamen is the male reproductive unit of the flower.
What part of the flower produces pollen male or female?
The style leads to the ovary that contains the female egg cells called ovules. The male parts are called stamens and usually surround the pistil. The stamen is made up of two parts: the anther and filament. The anther produces pollen (male reproductive cells).
Where are female gametes formed in flowering plants?
In flowering plants, the female gametes form in the ovary of the pistil.
What part of the flower produces male cells?
A stamen consists of an anther (which produces pollen, the male reproductive cell) and a filament.
Do all flowers have both male and female parts on them?
Flowers can have either all male parts, all female parts, or a combination. Flowers with all male or all female parts are called imperfect (cucumbers, pumpkin and melons). Flowers that have both male and female parts are called perfect (roses, lilies, dandelion).
Which is the male part of the plant?
stamen, the male reproductive part of a flower. In all but a few extant angiosperms, the stamen consists of a long slender stalk, the filament, with a two-lobed anther at the tip. The anther consists of four saclike structures (microsporangia) that produce pollen for pollination.
What is the female part of the flower called?
Pistil is the name of the female floral organ. The pistil consists of a long cylindrical central part, called a style, that connects the lower ovary to the upper stigma, which receives and holds pollen. There may be a single pistil, as in the lily, or several to many pistils, as in the buttercup.
How do you know if a flower is male or female?
Male flowers (top) produce pollen from the numerous stamens. Female flowers (bottom) have a well-developed ovary with long sticky stigmas in the centre. Although female flowers have stamens, they do not produce functional pollen.
Where is the male gamete formed I in humans II in flowering plants?
(i) In humans, the male gametes are formed in the testes. (ii) In flowering plants, the male gametes are formed in the anther of the stamen.
What helps to transfer the male gametes through the style into the ovary?
Explanation: The pollen tube acts as a conduit to transport the male gamete cells from the pollen grain—either from the stigma (in flowering plants) to the ovules at the base of the pistil or directly through ovule tissue in some gymnosperms.
Which flower part is often brightly colored and helps attract insects?
Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators.
What is androecium and gynoecium?
Androecium and gynoecium are the two, opposite reproductive organs of the flower, the sexual reproductive structures in angiosperms. Androecium is also called stamens, which comprises of anther and filaments while gynoecium is also called the pistil or carpel, which comprises of stigma, style, and ovary.
What is the fusion of male and female gametes called?
In sexual reproduction new organisms are produced from the fusion of a male sex cell with a female sex cell. This fusion of gametes is called fertilisation.
