  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...

NUTRITION 5.1 WHAT ARE LIFE PROCESSES Life processes are basic processes that living organisms perform to maintain their existence. Examples include nutrition, respiration, circulation, excretion, locomotion, growth, reproduction, and response to stimuli. 5.2 NUTRITION Nutrition is the process by which living organisms obtain energy and essential nutrients for the growth, maintenance, and repair of body tissues. Nutrition can be classified into two types: autotrophic and heterotrophic. 5.2.1 Autotrophic Nutrition Autotrophic nutrition is the mode of nutrition in which organisms produce their food from inorganic substances such as carbon dioxide and water, using energy from sunlight. Photosynthesis is the process by which autotrophs carry out this type of nutrition. Autotrophs use photosynthesis to fulfill their carbon and energy requirements by converting carbon dioxide and water into carbohydrates in the presence of sunlight and chlorophyll. Carbohydrates not used immediately are stor...
