Solution : In the process of layering, a section of an aerial stem develops roots while still connected to the parent plant and eventually separates to become a separate plant. The process of asexual reproduction known as “vegetative reproduction” involves the vegetative portion of the parent plant giving birth to a new plant. Definition : …
Solution : The cutting method only involves one plant, and the new plant is genetically similar to the old one. While grafting involves two plants and results in a new plant that is entirely distinct from its parents.
Solution : The first advantage of this method of propagation is the production of plants with desirable traits. Additionally, immature stems can be induced to flower and yield fruit quickly with this technique.
Solution : Apple and orange trees are propagated by the method of grafting.
Solution : Grafting In grafting, two plants are chosen that have the desired features. The stock is cut slantingly after the plant that was selected as a scion has been cut first. The scion is then put tightly together and placed over the stock. They are either knotted with a cloth or covered with a …
Solution : A stock is the lowest part of the graft, which is the stem with roots. The term “scion” refers to the upper part of the graft, or the stem without roots.
Spore Formation Even in many simple multi-cellular organisms, specific reproductive parts can be identified. The thread-like structures that developed on the bread in above are the hyphae of the bread mould (Rhizopus). They are not reproductive parts. On the other hand, the tiny blob-on-a-stick structures are involved in reproduction. The blobs are sporangia, which contain …
Tissue culture In tissue culture, new plants are grown by removing tissue or separating cells from the growing tip of a plant. The cells are then placed in an artificial medium where they divide rapidly to form a small group of cells or callus. The callus is transferred to another medium containing hormones for growth …
Solution : Differences between internal and external fertilisation Internal fertilization Fertilisation takes place outside the female’s body A large number of male and female gametes are released in the surrounding medium (like water). Organisms that use external fertilization to reproduce must either live in the water or return to the water for reproduction. As the …
Q. Differences between internal and external fertilization . Read More »
Solution : The site of fertilisation in human being is Ampulla of the fallopian tube. Human fertilization is the fusion of a human egg and sperm, usually occurring in the ampulla of the fallopian tube.
