Question

pls give me tissue chapter note all definations ,differences? pls fast tomorrow is my exam .

Answer 1

A group of cells are join together to perform various function is called tissue.

plant tissue- there are two types of plant tissue:-

1. permanent tissue
2. meristematic tissue.

animal tissue- animal tissue are of four types:-
1. epithelial
2. muscular
3. connective
4. nervous


hope it helps
best of luck for ur exam

thanks..

Answer 2

Topics in the Chapter

• Introduction

→ Features of meritematic tissues
→ Classification of meristematic tissues on the basis of origin
→ Primary (Promeristem)
→ Secondary merismetic tissues
→ Classification of meristematic tissues on the basis of location
→ Apical meristem
→ intercalary meristem
→ Lateral meristem
• Permanent Tissue
• Simple permanent tissue
→ Protective tissues
→ Epidermis
→ Functions of epidermis
→ Cork or Phellem
→ Functions of cork
→ Supporting Tissues
→ Parenchyma
→ Collenchyma
→ Sclerenchyma-Strengthening tissues
→ Sclereids
→ Fibers
• Difference between Parenchyma, Collenchyma and Sclerenchyma
• Complex Permanent tissues
• Xylem
→ Tracheids
→ Vessels
→ Xylem parenchyma
→ Xylem sclerenchyma
• Phloem
→ Sieve tubes
→ Companion cells
→ Phloem fibre
→ Phloem parenchyma
→ Leptome

Meristematic Tissue

→ These are simple living tissues having thin walled compactly arranged immature cells which are capable of division and formation of new cells.

Permanent Tissue

→ The permanent tissues are composed of those cells which have lost their capability to divide.

→ They have definite shape, size and thickness. The permanent tissue may be dead or living.

→ The division & differentiation of the cells of meristematic tissues give rise to permanent tissues.

→ In cell differentiation, developing tissue and organs change from simple to more complex forms to become specialized for specific functions.

→ The cells of permanent tissue loose the capacity to divide and attain a permanent shape, size and function.

ITS VERY BIG CHAPTER
IT IS NOT POSSIBLE TO WRITE ALL NOTES
