NCERT Solutions for Class 11 Biology Chapter 3 - Plant Kingdom


NCERT Solutions for Class 11 Biology Chapter 3 - Plant Kingdom: Here you will study about the Plant Kingdom. It includes algae, bryophytes, pteridophytes, gymnosperms, and angiosperms. Algae are chlorophyll-bearing simple, thalloid, autotrophic and largely aquatic organisms. Depending on the type of pigment possessed and the type of stored food, algae are classified into three classes, namely:

  • Chlorophyceae,
  • Phaeophyceae, and
  • Rhodophyceae.

Algae usually reproduce vegetatively by fragmentation, asexually by the formation of different types of spores and sexually by the formation of gametes which may show isogamy, anisogamy or oogamy.

In Biology Chapter 3 - Plant Kingdom, you will learn about all of those categories which comes under the Plant Kingdom. Bryophytes are plants which can live in soil but are dependent on water for sexual reproduction. Their plant body is more differentiated than that of algae. It is thallus-like and prostrate or erect and attached to the substratum by rhizoids. They possess root-like, leaf-like and stem-like structures. The bryophytes are divided into liverworts and mosses.

Here are the important topics of Class 11 Biology Chapter 3 - Plant Kingdom has given as below:

3.1 Algae

    3.1.1 Chlorophyceae

    3.1.2 Phaeophyceae

    3.1.3 Rhodophyceae

3.2 Bryophytes

    3.2.1 Liverworts

    3.2.2 Mosses

3.3 Pteridophytes

3.4 Gymnosperms

3.5 Angiosperms

3.6 Plant Life Cycles and Alternation of Generations

Chapter 3 - Plant Kingdom of NCERT book will also tell you about the gymnosperms and angiosperms. The gymnosperms are the plants in which ovules are not enclosed by an ovary wall. After fertilization, the seeds remain exposed and therefore these plants are called naked-seeded plants. The gymnosperms produce microspores and megaspores which are produced in microsporangia and megasporangia borne on the sporophylls.

In angiosperms, the male sex organs (stamen) and female sex organs (pistil) are borne in a flower. Each stamen consists of a filament and an anther. The anther produces pollen grains (male gametophyte) after meiosis. The pistil consists of an ovary enclosing one to many ovules. Within the ovule is the female gametophyte or embryo sac which contains the egg cell.

After going through Class 11 Biology Chapter 3 - Plant Kingdom line by line, you must be able to answer the following questions:

  • Q1. When and where does reduction division take place in the life cycle of a liverwort, a moss, a fern, a gymnosperm, and an angiosperm?
  • Q2. Name three groups of plants that bear archegonia. Briefly describe the life cycle of any one of them.
  • Q3. Both gymnosperms and angiosperms bear seeds, then why are they classified separately?

If you are unable to answer them by yourself, then NCERT Solutions for Class 11 Biology Chapter 3 - Plant Kingdom will help you to answer them. Also, try to solve all the question given in NCERT with the help of Solutions for NCERT Class 11 Biology Chapter 3 - Plant Kingdom.

Apart from these questions, you will also learn about a few short term questions about which you will get to know when you will go through the NCERT Class 11 Biology Chapter 3 - Plant Kingdom thoroughly, as they are very important like:

  • Natural classification systems
  • Artificial classification systems
  • Phylogenetic classification systems
