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.

Q2.
Which of the following options correctly identifies the plants their groups from the following structure?
Solution
(a) A-Funaria-Moss; B-Sphagnum-Moss
(a) A-Funaria-Moss; B-Sphagnum-Moss
Q3.
A mature pollen grain of Pinus has
Solution
(c) In Pinus, the microspore nucleus divides by a periclinal wall and forms a very small prothallial cell and large central cell. The central cell cuts off a second prothallial cell and antheridial cell. The nucleus of the antheridial cell divides to form generative cell and tube cell. Thus, the pollen grain of Pinus is sheded at four-celled stage when it consists of two vegetative prothallial cells, a generative cell and a tube cell.

(b) Chilgoza a gymnospermic seed that is eaten as dry fruit is produced by Pinus gerardiana
(b) Chilgoza a gymnospermic seed that is eaten as dry fruit is produced by Pinus gerardiana
Q5.
Which of the following statement is correct about the gametophytic stage in the alteration of generation with in the life cycle?
Solution
(a) Gametophyte is gamete bearing, haploid multicelled stage of many plants, beginning with haploid spores and ending at fertilisation

Q7.
The gametophyte of moss is
Solution
(d) Protonema is the juvenile stage of moss. It results from the germinating meiospore. When fully grown, it consists of a slender green, branching system of filaments called the protonema

Q8.
Calyptra develops from
Solution
(a) Calyptra is a covering developed from the ventre of archegonium in bryophytes and pteridophytes. It acts as a transpiration shield around the immature capsule and provides protection to the young capsule.

Q9.
A fern differs from a moss in having
Solution
(d) A fern (pteridophyte) differs from a moss (bryophyte) in the presence of independent sporophyte, while in moss the sporophyte is simpler than the gametophyte and remains attached to the parent gametophyte throughout its life. This sporophyte is dependent upon gametophyte partially or wholly for its nutrition.
