Permanent tissue

• Taking up a permanent shape, size and function is
  called differentiation
• These are of two types SIMPLE PERMANENT TISSUE
  AND COMPLEX PERMANENT TISSUE

7
SIMPLE Permanent tissue (Parenchyma)

• Parenchyma- Loosely packed
•                     Thin walled cells
•                     Intercellular spaces
•                     Contains chloroplast and
  prepares food by photosynthesis 
•                     Large cavities so that plant
  can float on water

8
collenchyma

• Elongated cells
• Less intercellular spaces
• Thicker at the corners
• Give flexibility so that plants can move
• Give mechanical support to the plant

9
Sclerenchyma
10
Chlorenchyma and aerenchyma

• Tissue containing chlorophyll is called
  chlorenchyma
• Tissues having large cavities and float on water
  are called aerenchyma

11
Complex permanent tissue

• Xylem phloem are the two types
• They are both conducting tissues
• Xylem consists of Tracheids, Xylem parenchyma,
  xylem fibres vessels

Phloem

• Sieve cells, sieve tubes, companion cells, phloem
  fibres, phloem parenchyma
• Sieve tubes are tublar cells with perforated
  walls
• Phloem transports food from leaves to other parts
  of the plant
• Except phloem fibres, other phloem cells are
  living cells
