What Class 11 Biology Chapter 3 Plant Kingdom Covers

The chapter classifies plants by increasing complexity, comparing the pigments, stored food and cell wall of each algal class, then tracing the shift from a dominant gametophyte in bryophytes to a dominant sporophyte in pteridophytes and seed plants. The official NCERT sections are listed below so students can see exactly what the chapter contains before they start.

Key Concepts You Will Study

Students should read this chapter as a sequence rather than as isolated groups, because each group solves a problem the previous one could not. Drawing the life cycle of one representative from each group is the single most useful thing to do here.

• The three algal classes Chlorophyceae, Phaeophyceae and Rhodophyceae with their pigments, stored food and flagella.
• Bryophytes as the amphibians of the plant kingdom, with liverworts and mosses.
• Pteridophytes as the first vascular plants, plus homospory and heterospory.
• Gymnosperms and naked seeds, and the closed carpel of angiosperms.
• Alternation of generations and the haplontic, diplontic and haplo-diplontic life cycles.

Why Download the NCERT Book PDF for This Chapter

Plant Kingdom is one of the most table-driven chapters in Class 11, and NEET repeatedly asks which pigment, which stored food or which life cycle belongs to which group. Those answers sit in the NCERT tables and nowhere else in the same form.

• NEET asks pigment, stored food and cell wall questions straight from the NCERT algae table.
• The life cycle diagrams for moss, fern and pine are the exact ones examiners reference.
• Haplontic, diplontic and haplo-diplontic cycles are examined using the NCERT figures.

How to Use the NCERT Book PDF for Plant Kingdom

Work through the chapter group by group and draw each life cycle yourself, marking clearly where meiosis happens and which generation is dominant. That single habit answers most of the questions this chapter can generate.

• Draw the life cycle of a moss, a fern and a gymnosperm, marking the meiosis point.
• Build one table of algal classes with pigments, stored food, cell wall and flagella.
• Note which generation is dominant in each group as you move up the sequence.
• Attempt the back exercises, then check them against the NCERT Solutions linked below.
