The Root Types of Root Systems1) Tap Root System (Dicot plants) 2) Fibrous Root System (Monocot plants) 3) Adventitious Roots Functions of Roots• Absorption – Uptake of water and minerals from soil.• Anchorage – Provides stability and support to the plant.• Storage – Stores reserve food materials.• Growth Regulation – Helps in synthesis of plant growth regulators. In simple words, roots play...
Notes on Morphology of Flowering Plants 🔹 Diversity in Higher Plants 🔹 Importance of Standard Classification 🔹 Basic Structure of Flowering Plants Despite their diversity, all angiosperms have common structures, and their modifications help them adapt to different environments.
Meiosis is essential for maintaining the chromosome number in sexually reproducing organisms across generations. Although it reduces the chromosome number by half, fertilization restores it, ensuring genetic stability. Additionally, meiosis introduces genetic variability through crossing over and independent assortment, leading to unique genetic combinations. These variations are crucial for evolution, as they enhance adaptability and...
Overview Meiosis II is initiated immediately after cytokinesis of Meiosis I. It resembles mitosis in its process. Results in the formation of four haploid daughter cells. Phases of Meiosis II 1. Prophase II: Begins immediately after cytokinesis, often before chromosomes fully elongate. Chromosomes become compact again. Nuclear membrane disappears...
