Reproduction in flowering plants Quiz-05
Dear Readers,
NEET is the most famous and important medical entrance examination held in our country. This exam is an objective type, an offline test which includes 4 sections namely– Physics, Chemistry, Botany, and Zoology. The maximum marks that can be scored are 720 marks and have 180 questions.
About half of the paper consists of questions from Biology, as the NEET exam essentially focuses on capacitating students to go for seats in medical courses. One of the most significant and crucial sections in the NEET exam is of Biology. It comprises of theories, descriptions, discoveries, diagrams, definitions, explanations of differences, and relations. The majority of the topics covered in the NEET syllabus are from the NCERT syllabus of Class 11 & 12 and other related sources become part of the rest of the syllabus.
Clear Exam curates a list of articles selected by professionals who recommend the highly vital topics for NEET exams. The table below takes you directly to the respective topic where the in-depth article and the MCQs are available for an easy and productive learning experience. Prior to solving NEET question papers or practicing mock tests, you must ensure to study the basic concepts in NEET and practice a few sample questions related to this exam. Students will be covered for all their studies as the topics are available from basics to even the most advanced.

Q2.
The process in which haploid embryo is formed from haploid egg without fertilization is called
Solution
(b) Apomixis or agamospermy is a reproductive process in plants that superficially resembles normal sexual reproduction but in which there is no fusion of gametes. In some apomictic flowering plants, there is no fertilization by pollen and the embryos develop simply by division of a diploid cell of the ovule.

Syngamy is the process in which
Solution
(a) Syngamy is the fusion of gametes, i.e, the union of nuclei of male gamete and female gamete in the process of reproduction. In angiosperms, generative fertilization is also called, syngamy.
