Chapter 4: Tissue — ICSE Class VII Biology Notes

Complete ICSE Class VII Biology notes on Tissue covering meristematic and permanent plant tissues (parenchyma, collenchyma, sclerenchyma, xylem, phloem) and four animal tissue types with examples and diagrams.

Key Concepts and Topics

Topics covered: Meristematic tissue, Permanent tissue, Animal tissues, Xylem, Phloem

Weightage: Approximately 8 marks in the exam

Important Points to Remember

  • Tissue: group of similar cells performing specific function
  • Meristematic tissue: actively dividing cells at growth points
  • Simple permanent: parenchyma (storage), collenchyma (flexibility), sclerenchyma (strength)
  • Complex permanent: xylem (water up) and phloem (food both ways)
  • Four animal tissues: epithelial, connective, muscular, nervous
  • Three muscle types: skeletal, smooth, cardiac
  • Blood is a connective tissue with liquid matrix

Frequently Asked Questions

Q: What is a tissue?

A: A tissue is a group of similar cells that perform a specific function together.

Q: What is the difference between xylem and phloem?

A: Xylem transports water upward and is made of dead cells. Phloem transports food in both directions and is made of living cells.

Q: Why is blood called a connective tissue?

A: Because it connects all body parts by transporting nutrients, oxygen, and waste, even though its matrix (plasma) is liquid.

Exam Preparation Tips

  • Focus on understanding concepts rather than rote memorization
  • Practice drawing and labelling diagrams regularly
  • Use comparison tables for topics that require differentiation
  • Solve previous year questions and practice papers
  • Review the chapter notes provided by Bright Tutorials for comprehensive coverage
