1. In what ways is vegetative propagation better than sexual reproduction? 2. Describe parts of flower in brief? 3. How is self pollination different from cross pollination? 4. How are fruits formed? 5. Why is dispersal of seed necessary for growth of plants?
Answers
Answer:
(1) Vegetative propagation is much better than sexual reproduction because it is first of all very easy and short term process on comparing with sexual reproduction which takes so much time to give birth to offsprings and other is that it do not need any other parents for such kind reproduction.
Four man parts of 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.
The carpels are female reproductive structures that produce egg cells and protect a developing baby plant, or embryo. The three main parts of a carpel are the stigma, style, and ovary. The stigma is where pollination occurs.
