Quick Revision Box: Chapter 6 - Tissues
- Tissue: A group of cells similar in structure and function.
- Plant Tissues: Classified as Meristematic (dividing) and Permanent (non-dividing).
- Meristem Types: Apical (tips), Lateral (girth), Intercalary (internodes).
- Simple Permanent Tissues:
- Parenchyma: Thin walls, living, storage/photosynthesis.
- Collenchyma: Irregular thick walls, living, flexibility.
- Sclerenchyma: Thick lignified walls, dead, strength.
- Complex Permanent Tissues: Xylem (water transport: tracheids, vessels, parenchyma, fibres) and Phloem (food transport: sieve tubes, companion cells, parenchyma, fibres).
- Epidermis & Stomata: Outer protective layer; stomata (guard cells) for gas exchange.
- Cork (Bark): Protective tissue with suberin, replaces epidermis in old stems.
- Animal Tissues:
- Epithelial: Covering/protection (Squamous, Cuboidal, Columnar, Ciliated).
- Connective: Support/binding (Blood, Bone, Ligament, Tendon, Cartilage, Areolar, Adipose).
- Muscular: Movement (Striated/Voluntary, Smooth/Involuntary, Cardiac).
- Nervous: Control/coordination (Neurons with axon, dendrites).
- Key Difference: Plant growth is localised (meristems); animal growth is more uniform.
Basic Level Questions
Chapter 6 Summary: Tissues - The Fabric of Life
This chapter unveils the fundamental concept of Tissues—the organized groups of cells that form the building blocks of all complex plants and animals. You will learn how division of labor at the cellular level leads to the formation of specialized tissues, each engineered for supreme efficiency in its specific role, be it transport, support, movement, or control.
We explore the stark contrast between plant and animal body designs. You'll master the classification of Plant Tissues, from the ever-dividing meristems to the specialized permanent tissues like parenchyma, collenchyma, and sclerenchyma, and understand the intricate plumbing system of xylem and phloem. The chapter then delves into the four primary types of Animal Tissues—epithelial, connective, muscular, and nervous—decoding their structure and function in maintaining life.
This website helps you solidify this knowledge through targeted chapter-wise MCQs. Practicing these questions tests your understanding of key definitions (like differentiation, meristem), structural adaptations (lignified walls, intercalated discs), and functional comparisons. This active recall is the most effective way to prepare for board exams and competitive tests, ensuring you can confidently identify tissues, explain their roles, and apply these concepts to solve exam problems.
