  What is Plant Anatomy? Plant anatomy is the study of internal structure and organization of tissues in plants. It helps in understanding: Functional adaptation Transport system Growth patterns Tissue Organization in Flowering Plants Flowering plants have three major tissue systems :  Epidermal Tissue System Components: Epidermis Single layer of compact cells No intercellular spaces Covered by cuticle (except roots) Cuticle Made of cutin Prevents water loss Stomata Present mainly on leaves Composed of guard cells Regulate: Gas exchange Transpiration Root hairs Extensions of epidermal cells Increase surface area for absorption Trichomes (in stem) Hair-like structures Protection + reduce transpiration  Functions: Protection Water conservation Gas exchange 🌿 B. Ground Tissue System  Types of Ground Tissue: 1. Parenchyma Living cells, thin cell wall Large vacuole Functions: Storage Photosynthesis ( chlorenchyma ) Air storage ( aerenchyma ) 2. Collenchyma Living cell...

ECOLOGICAL INTERACTIONS

 Ecological interactions refer to the relationships and interactions between organisms and their environment within an ecosystem. These interactions encompass the various ways in which organisms interact with one another and with their physical surroundings. They involve the exchange of energy, nutrients, and information among different species and their environment. Ecological interactions can be classified into different types, including predation, competition, mutualism, commensalism, parasitism, amensalism, and symbiosis. TYPES OF ECOLOGICAL INTERACTION PREDATION Roles: Predators are typically animals that actively search for, pursue, and capture their prey. They have adaptations such as sharp teeth, claws, speed, or stealth that aid in capturing and subduing their prey. Prey, on the other hand, are organisms that are consumed by predators and have adaptations for defense, camouflage, or escape. Regulation of Prey Populations: Predation helps regulate the population size and di...
