Please refer toMorphology of Flowering PlantsClass 11 Biology notes and questions with solutions below. These revision notes and important examination questions have been prepared based on the latest Biology books for Class 11 BiologyMorphology of Flowering PlantsNotes and Questions • Morphology is the study of external forms of organisms. • A flowering plant (Angiosperm) has 2 parts: Root system (underground part) & Shoot system (portion above the ground). THE ROOT It is the underground part formed from radicle of embryo. Root systems are 3 types: • Tap root system: It consists of primary roots (tap root) and its branches (lateral roots such as secondary roots, tertiary roots). Seen in dicots. Primary root is elongated from radicle. E.g. Mustard plant. • Fibrous root system: In monocots, primary root is short lived and is replaced by many roots. They originate from the base of stem to form fibrous root system. E.g. Wheat. • Adventitious root system: Roots that arise from parts other than radicle. E.g. Grass, Monstera and banyan tree. Regions of the Root • Root cap: It is the covering at the apex of root. It protects the tender apex of the root. • Region of meristematic activity: Seen above the root cap. Here, the cells are very small, thin-walled and with dense protoplasm. They divide repeatedly. • Region of elongation: Region just above the meristematic region. Here, cells undergo rapid elongation and enlargement. Helps in growth of the root in length. • Region of matura...

Following are Morphology of Flowering Plants Notes for Class 11 Biology. These revision notes have been prepared by expert teachers of Class 11 Biology as per the latest NCERT, CBSE, KVS books released for the current academic year. Students should go through Chapter 5 Morphology of Flowering Plants concepts and notes as these will help you to revise all important topics and help you to score more marks. We have provided Chapter 5 Morphology of Flowering Plants Notes Class 11 Biology ➤ Morphology is the study external structure of plant. ➤ This description is require in classification and evolutionary biology. ➤ Ukranian biologist Dr. Katharine Esau wrote two famous books – • “PLANT ANATOMY” (1954) • “THE ANATOMY OF SEED PLANT” (1960)o referred to as Webster’s of plant biology 1. THE ROOT: o Positive geotropic, o Negative phototropic 2. TAP ROOT SYSTEM: o Primary root with several orders of lateral roots (secondary, tertiary roots etc)makes the tap root system. o Primary root is direct elongation of radicle. o Tap root system is found in dicot plants e.g. mustard plant. 3. FIBROUS ROOT SYSTEM: o It is originate from the base of stem. o It is found in monocots e.g. Wheat etc. o In monocot first root is primary root which is short lived and replaced by fibrous roots. 4. ADVENTITIOUS ROOT: o Root which arise other than radicle.e.g. monstera, banyan and grass. o The main functions of the root system are absorption of water and minerals from the soil, providing a proper anchora...

Class 11 Biology chapter 5 notes will teach you about the different parts of plants. Morphology Of Flowering Plants Class 11 notes explores the complete characteristics of flowering plants, including their structure, functions, classifications, and other morphological characteristics of roots, stems, leaves, flowers, fruits, and seeds. Flowering plants, according to notes for Class 11 Biology chapter 5, vary greatly in shape, size, structure, mode of nourishment, life span, habit, and environment. Table of contents Plant Physiology is not included in the Also, students can refer, • • NCERT Class 11 Biology Chapter 5 Notes With 300,000 known species, flowering plants are the most diverse group of land plants. These plants, also known as angiosperms, are seed-bearing fruits. Flowering plants are thought to have evolved from gymnosperms during the Triassic period, with the first flowering plant appearing 140 million years ago. Standard technical terms and definitions are required for any successful attempt at classification and understanding of any higher plant (or, for that matter, any living organism). We also need to know about the possible differences in various parts identified as adaptations of the plants to their environment such as adaptations to varied habitats, for protection, climbing, storage, and so on. The Root : • In most of the dicotyledonous plants, direct radicle elongation results in the formation of a primary root that develops inside the soil. It has late...
