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. .
Q1.
Laminarin and manitol of class-Phaeophyceae (brown algae) are
Solution
(b) In class-Phaeophyceae the accumulation product of photosynthesis is D-mannitol or laminarin
(b) In class-Phaeophyceae the accumulation product of photosynthesis is D-mannitol or laminarin
Q2.
In flowering plants meiosis occurs at the time of
Solution
(d) In flowering plants, a cross section of the developing anther displays four chambers. These chambers are called pollen sacs. Each pollen sac is filled with cells containing large nuclei. As the anther grows each of these cells goes through two meiotic divisions, forming a tetrad. These cells are called microspores. Each one of these microspores eventually becomes a pollen grain and in carpel meiosis takes place at the time of megaspore from megaspore mother cell

Q3.
Which of the statement is correct about Marchantia?
I. Plant body is thallus-like structures closely attached to substrate
II. Sporophyte is differentiated into food, seta and capsule
III. Gemma cup located on the thalli
Solution
(d) The vegetative plant body of Marchentia is a dorsiventral lobed thallus. The sporophyte of bryophytes is known as sporogonium. The Sporogonium of Marchentia is differentiated into foot, seta and capsule. Asexual reproduction in Marchentia is takes place by the formation of gammae, which are located on the thalli

Q5.
Choose the incorrect statement about mosses?
Solution
(c) In mosses only capsule bears spores, which gives rise to gametophyte after meiosis and the sporophyte in masses is more elaborate than that in liverworks
(c) In mosses only capsule bears spores, which gives rise to gametophyte after meiosis and the sporophyte in masses is more elaborate than that in liverworks
