Question

Development of a new plant from tissue or structure that drops or is Separated from the parent plant is called
A. Parthenogenesis
B. Vegetative propagation
C. Exocytosis
D. Nodal growth

Answer 1

The process by which development of a new plant from tissue or structure that drops or is Separated from the parent plant occurs is a type called asexual reproduction. The most striking example of this fertility is Bryophyllum leaf. Like other leaves, they carry out photosynthesis, their normal function, but they also can produce one or more plants from the gaps in their fields.

Complete answer:
Before answering the question let’s study about some important points.
Parthenogenesis-Typically, an unfertilized egg does not develop into a new individual until it is fused or fertilized with sperm, but in some cases, the egg develops without fertilization. This special type of sexual reproduction, in which the egg develops without fertilization, is called parthenogenesis.
Vegetative propagation -vegetative propagation is a form of asexual reproduction of plants in which new plants grow from fragments or specific reproductive structures of the parent plant. When plants multiply, all parts of the plant, i.e. Stems, roots, leaves or shoots can produce new plants. The most striking example of such fertility is Bryophyllum leaves. Like other leaves, they perform their normal function of photosynthesis but are also capable of producing more than one plant in the crevices of their fields.
Exocytosis-Compared to endocytosis, it is the process of transporting substances from the inside of the cell to the outside using the energy. Therefore, it is a kind of active transport mechanism opposite to endocytosis. Special vesicles attached to a cell membrane containing cell particles, usually through these extracellular mechanisms, release cellular contents outside the cell. This mechanism is used to remove waste products from cells, transport hormones and proteins, transmit chemical signals between cells, and build cell membranes. The vesicles involved in exocytosis are formed by the Golgi apparatus, endosomes, and presynaptic neurons. These vesicles fuse with the cell membrane and, depending on their function, can be complete or transient vesicles.
So, the correct answer is “Option B”.

Note:
For seed plants, propagation of vegetation by natural methods is very common. Often, plant organs such as roots, stem, and leaves sprout randomly to form new plants. This design is also called a plant rag. Gardeners and gardeners have used a variety of plant breeding methods used by plants in nature. This practice is an artificial means of asexual reproduction. Since the process of asexual reproduction involves simple cell division, the traits of the parent plant reproduce correctly in the offspring. Very beneficial plants like bananas and some citrus fruits are sterile and seedless. Propagation from cuttings is the only way to get more of these types of plant.
