Plant Kingdom Quiz-02
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.

Q1.
Haploid structure of Funaria is
Solution
(b) Protonema is slender, green, branched and filamentous gametophytic phase in the life cycle of Funaria.
(b) Protonema is slender, green, branched and filamentous gametophytic phase in the life cycle of Funaria.
Q2.
In gymnosperms, during pollination pollen grains are released from the microsporangium and transferred to
Solution
(a) Pollination occurs once a genetically compatible pollen grain lands directly on the ovule. The pollen grain germinate and grows into the ovule, penetrating the female gametophyte and eventually fertilising an egg nucleus

Q3.
Seed habit is linked to
Solution
(b) Some of the pteridophytes produce smaller spores called microspores and larger one called megaspore. This nature is called heterospory. In angiosperms there is only one functional megaspore. The male and female gametes fuse to form zygote which eventually developes into embryo. The embryo forms the seed.

Q5.
Plants have ….. in their life cycle
Solution
(a) Land plants all have heteromorphic alternation of generations, in which the sporophyte and gametophyte are distinctly different

Q6.
In brown algae, brown colour is due to presence of
Solution
(b) Brown algae are vary in colour from olive green to various shades of brown depending upon the amount of the xanthophyll pigment, fucoxanthin present in them.

Q8.
Which of the following is not correctly matched?
Solution
(d) Volvox is a freshwater green alga. It occurs in colonies or coenobium (in definite number or group), surrounded by a pellicle (gelatinous glycoprotein) layer. Each pyriform shaped cell has two long similar and smooth flagella, eye spot, cup-shaped chloroplast with pyrenoids and contractile vacuoles.
