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.
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...
General Characteristics Gymnosperms (gymnos = naked, sperma = seed) have exposed ovules and seeds (not enclosed by fruit). Include medium to tall trees & shrubs. The giant redwood tree (Sequoia) is one of the tallest tree species. Root System Generally tap roots. Some have fungal mycorrhizal associations (e.g., Pinus)....
General Characteristics Angiosperms (flowering plants) have ovules enclosed within fruits (unlike gymnosperms, where ovules are naked). Pollen grains & ovules develop inside specialized reproductive structures called flowers. Seeds are enclosed within fruits. Largest group of plants, adapted to a wide range of habitats. Diversity in Angiosperms Range in size...
General Characteristics Pteridophytes include horsetails & ferns 🌿. Used for medicinal purposes, soil-binding, and as ornamental plants. First terrestrial plants to develop vascular tissues (xylem & phloem) 🌱. Mostly found in cool, damp, shady places, though some grow in sandy soils. Life Cycle & Structure Main plant body is...
Habitat Found in moist, shady places such as:✅ Banks of streams✅ Marshy ground✅ Damp soil✅ Bark of trees✅ Deep woodsStructure Plant body is thalloid (flat, ribbon-like structure), e.g., Marchantia. Thallus is dorsiventral (having a distinct upper and lower surface) and closely attached to the substrate. Leafy liverworts have tiny...
