PLANT TISSUE 🌿🌿🌿🌿

Plant tissues are groups of similar cells that work together to perform specific functions in plants. They are mainly divided into two types: 1. Meristematic Tissue Function: Responsible for plant growth. Cells: Actively dividing, small, with a large nucleus and thin walls. Types: Apical Meristem: Found at root and shoot tips; helps in lengthwise growth. Lateral Meristem: Found along the sides of stems and roots; responsible for increase in thickness (e.g., cambium). Intercalary Meristem: Located at internodes or base of leaves; helps in regrowth (common in grasses). 2. Permanent Tissue These tissues are formed from meristematic tissues and have lost the ability to divide. They are of two types: a) Simple Permanent Tissue (Made of one type of cell) Parenchyma: Living, thin-walled, loosely packed. Functions: storage, photosynthesis (if chloroplasts present). Collenchyma: Living, with thickened corners. Provides flexibility and mechanical support (e.g., in stems of young plants). Sclerenchyma: Dead cells with thick walls. Provides strength and rigidity (e.g., coconut husk). b) Complex Permanent Tissue (Made of more than one type of cell) Xylem: Transports water and minerals from roots to other parts. Components: Tracheids, vessels, xylem parenchyma, xylem fibres. Phloem: Transports food from leaves to other parts. Components: Sieve tubes, companion cells, phloem parenchyma, phloem fibres. #neet #aiims #ncertbiology #ncert #ytshorts #shortsfeed #shortvideo #education
