Anatomy of Flowering Plants — Class 11 CBSE Biology revision notes
A 4-page visual revision sheet for Anatomy of Flowering Plants, written for Class 11 CBSE Biology. Formulas, diagrams and the traps that cost marks, laid out to be read the night before rather than the term before. Free, and it opens inside CapCompass.

Anatomy of Flowering Plants in one look
the internal tissues behind every root, stem and leaf
Tissues, permanent vs meristematic
- a tissue: similar cells working together for one function
- meristematic tissue: cells that keep dividing, found at specific growing points
- permanent tissue: non-dividing cells with a fixed shape, formed once meristematic cells differentiate
Meristems, by position
- apical meristem: at the tip of the root and shoot, responsible for growth in length
- intercalary meristem: between permanent tissue, at leaf or internode base, as in grasses
- lateral meristem: vascular and cork cambium along roots and stems, adds girth
A generic plant cell
- every plant cell has a cellulose wall around the membrane, nucleus and organelles inside
- plastids are membrane-bound organelles: store starch, or in green tissue, photosynthesise
Simple permanent tissues
- parenchyma: thin-walled living cells, large gaps, form the ground tissue filling most of the body
- chlorophyll-bearing parenchyma is called chlorenchyma
- collenchyma: living cells with corner wall thickening (cellulose + pectin), flexible support for growing parts
- sclerenchyma: dead cells, hard lignified wall, rigid strength; long fibres or short irregular sclereids
Collenchyma vs Sclerenchyma
- living cells at maturity
- wall thickened unevenly, at the corners, with cellulose and pectin
- flexible support, common in young stems and leaf stalks
- dead cells at maturity, no living protoplasm
- wall thickened uniformly, with lignin
- rigid support, common in mature stems and seed husks

How CapCompass uses this sheet
These notes are not a standalone PDF. CapCompass plans Biology chapter by chapter against your real exam dates and free hours, and when the plan reaches Anatomy of Flowering Plants the sheet opens inside the study block itself — at the page covering the sub-topic that block is on, with the timer still running. Revision arrives at the moment the plan says revise, instead of having to be gone looking for.
