Plant Kingdom Quiz-06
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.

Solution
(c) In Cyas, pollination occurs at three called stage. Microspore is sheded from the microsporangium at three-celled stage, i.e., prothallial cell, tube cell and generative cell.

Q4.
While entering in the neck of a fern archegonium, sperms shows
Solution
(b) In ferns about 32 multiflagellate, spirally coiled sperms are produced in antheridium. These sperms swim towards open archegonia due to the presence of malic acid in the later, i.e., they show chemotaxy.

Q5.
Heterosporous pteridophytes always produce
Solution
(b) Heterosporous pteridophytees like Selaginella and Marsilea always produce dioecious gametophyte because microspore will form male gametophyte and megaspore will form female gametophyte.

Q8.
The peculiar feature of Marchantia palmata is
Solution
(b) An androgynous receptacle is the one which contains antheridia on upper side and archegonia on lower side, e.g.,Marchantia.

Q9.
In algae, vegetative reproduction mainly takes place by
Solution
(c) Fragmentation. Algae reproduce by vegetative, asexual and sexual methods. The vegetative and asexual methods are abundant. Algae reproduce vegetatively by fragmentation and asexually by means of motile or non-motile spores. Sexual reproduction occurs through fusion of two gametes

Q10.
Gymnosperms produce neither flower nor fruit because they do not possess
Solution
(b) Gymnosperms lack ovary thus, fruits are absent. They possess naked seeds due to presence of naked ovules
