Question

Assertion: The plants in which foreign genes have been introduced through genetic engineering are called transgenic plants.
Reason: Transgenic animals have been extensively used as models for biomedical research.
A. Both Assertion and reason are correct and reason is the correct explanation for assertion.
B. Both Assertion and reason are correct and reason is not the correct explanation for assertion.
C. Assertion is correct but Reason is incorrect.
D. Both assertion and reason are incorrect.

Answer 1

Plants that have been genetically modified have been used for scientific research, to develop new colours in plants, to deliver vaccines, and to improve agriculture. Many plant cells are pluripotent, which means that a single cell from a mature plant can be extracted and used to create a new plant given the correct conditions. Plants that have been genetically engineered and are utilised in agriculture are known as genetically modified crops.

Complete explanation:
Option A: Plants that have had foreign DNA introduced into them through genetic engineering are known as transgenic plants or genetically modified plants. In vivo investigations using transgenic animals are being conducted to investigate gene functions, regulation, and the role of genetic mutations in disease development.
So, option A is incorrect.
Option B: Plants whose DNA has been altered by genetic engineering are referred to as transgenic plants. Transgenic mice have become an important tool in functional genomics for developing disease models and validating novel medications. The addition of foreign genetic information to animals and the targeted inhibition of endogenous gene expression are both examples of transgenesis.
So, option B is correct.
Option C: Transgenic plants, also known as Genetically Modified Plants, are plants that have had foreign DNA injected into them through genetic engineering. In vivo investigations using transgenic animals are being conducted to investigate gene functions, regulation, and the role of genetic mutations in disease development.
So, option C is incorrect.
Option D: Plants that have had their DNA altered through genetic engineering are known as transgenic plants. In functional genomics, transgenic mice have become an important tool for establishing illness models and evaluating new treatments. Transgenesis involves the introduction of foreign genetic information into animals as well as the targeted suppression of endogenous gene expression.
So, option D is incorrect.

Therefore, Option B is the correct answer.

Note:
Transgenic plants are those that are created by inserting foreign DNA into a cell and growing a plant from it. Transgenic plants include maize, rice, brinjal, cabbage, cauliflowers, potato, and tomato, to name a few. Transgenic plants are a fantastic approach to create plants with desired and advantageous traits, and they can help with agricultural production and yields. It can allow for the production of more crops that can be sustained for extended periods of time while also tolerating illnesses and pests. Transgenic plant production allows us to meet and cater to the wants of an ever-increasing population, resulting in the creation of more appealing food.
