Question

In some plants, typically halophytes, seeds germinate with fruits while they are still attached to their parent plant. Identify the phenomenon from the given options.
A. Sesimonasty
B. Vivipary
C. Monocarpic
D. Vernalization

Answer 1

Hint: The similar kind of condition can be seen in the animals where the embryo grows up to a certain point in its life cycle and the detaches from the parent organism. There are two types of this condition.

Complete answer:
The animals possess two types regarding the growth and birth of their offspring. One being the laying of eggs and incubation of them till they hatch and the other is pregnancy where the baby grows inside the parent and it gives birth to an individual. The former condition is called the oviparous and later called the viviparous conditions. In the question we are somewhat given the idea like the conditions of the viviparous condition where the seed is germinating and growing attached to the parent and it only detaches itself after it has reached a certain point of its life cycle. This type of condition in plants is called vivipary. In animals they give birth but in plants they release the seeds into nature.
Now the other option if we take into consideration, first of them is seismonasty which is not at all related to the germination of seeds and even the other remaining options are also not related to the germination. Seismonasty is the response of a plant or fungi or plants to vibrations produced nearby. The monocarpic term is a condition where the plants bloom only once in their life cycle and after that they eventually die and hence complete their life cycle. The last option is vernalization. This term is somewhat related to the germination but we can say that this is a type of artificial germination where the seeds are subjected to lower temperature giving winter-like condition so as to germinate the seed. In this the seeds are grown normally inside labs and parent plants are not there if they germinate by attaching.

Hence, the correct answer is option (B).

Note: The condition of vernalization and vivipary should not be confused together because in one situation the seeds germinate naturally but in the other case the seeds are allowed to germinate in artificial conditions.
