[Biology Class Notes] on MCQs on Pteridophyta Pdf for EXAM

All living beings on the planet are classified into five different kingdoms. They are kingdom monera, kingdom Protista, kingdom fungi, kingdom Plantaeplantae and kingdom Animalia. Classification and nomenclature were adopted by specialists in the field to make the process of understanding the living world more convenient. All biotic elements fall into one of these categories based on whether they are unicellular or multicellular, whether they reproduce through a particular method, whether they have or not have a cell wall etc. 

Kingdom Plantae is an important kingdom in the living world. It encompasses five categories, namely thallophyta, Bryophyta, Pteridophyta, gymnosperms and angiosperms. They are eukaryotic and often multicellular. They adopt various methods for reproduction like fragmentation, budding and sexual reproduction. Plant species are classified into these five categories based on so many criteria like their mode of reproduction etc. But these distinctions are not always rigid and sometimes certain species can occupy the border positions until the problem is solved by specialists on taxonomy and nomenclature.

Pteridophytes are the third category in this classification. They are less sophisticated than gymnosperms and angiosperms but have a more complex body structure than thallophytes and bryophytes. This is because they are vascular and reproduce through spores. This sophisticated body organization of the thallophytes has evolved over centuries on the planet. The same trend is observed in nearly all the kingdoms where evolution takes place gradually. For convenience, specialists have arranged kingdoms and subgroups in the taxonomy according to the level of evolution each plant or animal species has undergone through the years.

What are Pteridophytes?

The pteridophyte is derived from two words; Pteron, meaning feather in Greek, and python means herb. So, this name was originally given to those plant groups that had well-shaped feather-like leaves. These plants carry no flowers or seeds. Therefore, they are also called Cryptogams, simply because their means of reproduction are secret. A cryptogam, Cryptogamae scientifically is a plant (in the broad sense of the word) that reproduces by spores, without flowers or seeds.

“Cryptogamae” is taken from Greek, that is, Kryptos meaning “hidden” + game meaning “to marry.” The hidden reproduction refers to the fact that cryptogams represent the non-seed-bearing plants without the production of seeds. We are in reality the first developed group of plants with a vascular tissue network for water and food transport. They’re found mostly in dark, damp areas. They include horsetails and ferns. The ferns are mostly used as ornamental plants.

Importance of MCQs

This set of Multiple – Choice Questions & Answers (MCQs) focuses on “pteridophytes.” These questions are short and sharp that cover the whole topic and let students assess their knowledge on a given topic.

NCERT often focuses on extensive learning of topics due to which the syllabus covers a vast range of topics to better prepare the students. In such a scenario, an easy method for students to remember the important topics is by solving MCQs whenever they can. In this manner, students will be able to go through a lot of topics in a short time. This will be convenient for students during their exam preparation. MCQs cover all important topics of any specific unit and can be used by students to evaluate if they have properly gone through any chapter.

Time and memory are two important factors in life for every student and this problem is efficiently solved with the help of MCQs. Revision using MCQs is very productive in learning and should be made an inevitable part of any curriculum. ’s MCQs on pteridophytes similarly solve the problem of time for students since they are crisp, to-the-point and easy to comprehend.
