Answer 1

Answer:

Peduncle: This is the stalk of the flower.

Receptacle: It is that part of the flower to which the stalk is attached to. It is small and found at the centre of the base of the flower.

Sepals: These are the small, leaf-like parts growing at the base of the petals. They form the outermost whorl of the flower. Collectively, sepals are known as the calyx. The main function of the calyx and its sepals is to protect the flower before it blossoms(in the bud stage).

Petals: This layer lies just above the sepal layer. They are often bright in colour as their main function is to attract pollinators such as insects, butterflies etc to the flower. The petals are collectively known as the corolla.

Stamens: These are the male parts of a flower. Many stamens are collectively known as the androecium. They are structurally divided into two parts:

Filament: the part that is long and slender and attached the anther to the flower.

Anthers: It is the head of the stamen and is responsible for producing the pollen which is transferred to the pistil or female parts of the same or another flower to bring about fertilization.

Pistil: This forms the female parts of a flower. A collection of pistils is called the gynoecium

pistil is of four types:

style -is a long slender stalk that holds the stigma. Once the pollen reaches the stigma, the style starts to become hollow and forms a tube called the pollen tube which takes the pollen to the ovaries to enable fertilization.

Stigma– This is found at the tip of the style. It forms the head of the pistil. The stigma contains a sticky substance whose job is to catch pollen grains from different pollinators or those dispersed through the wind. They are responsible to begin the process of fertilization.

Ovary – They form the base of the pistil. The ovary holds the ovules.

Ovules– These are the egg cells of a flower. They are contained in the ovary. In the event of a favorable pollination where a compatible pollen reaches the stigma and eventually reaches the ovary to fuse with the ovules, this fertilized product forms the fruit and the ovules become the seeds of the fruit.
