Learn everything (25 cards)
Give two types of plant tissue
merismetic tissue
permanent tissue
Give two types of merismetic tissue
Apical meristematic tissue
Lateral meristematic tissue
Define permanent tissue
matured tissue that have experience or are experience diffrentiation
Give three types of permanent tissue
Epidermal
Ground
Vascular
Name epidermal cell walls which are exposed to the air and have a waxy and waterproof layer
cuticle
Functions of cuticle
- Reduce loss of water through evaporation( transpiration )
- Protect leaf from mechanical injuries and pathogens
Name two modified epidermal cell
- Guard Cell
* Root hair cells
Function of guard cell
control opening of stoma
Function of root hair cell
increase the surface area of the root for watet and mineral salt absorbtion
Name three types of ground tissue
- Parenchyma
- Collenchyma
- Sclerenchyma
Which ground tissue consist of living cells and do not undergo differentiation
parenchyma tissue
Ground tissue which always turgid to provide support and maintaining shape of herbacous plants
parenchyma tissue
Ground tissue which involve in photosynthesis ( gaseous exchange )
and store starch and sugar
parenchyma tissue
Ground tissue which involve in repair and regeneration of plant tissue
parenchyma tissue
Ground cell which mature into cell that are flexible
Collenchyma tissue
Ground tissue which have cell wall made of pectin and hemicellulose
Collenchyma tissue
Stage of cell wall of ground tissue
Sclerenchyma > Collenchyma > Parenchyma
Sclerenchyma tissue consist of ?
dead cells
Funct of sclerenchyma tissue
- provide support and mechanical strength to part of matured
- Help in transport water and nutrient
Xylem made of ?
dead cell without cytoplasm
Cell wall of xylem contain
lignin
Function of xylem
transport water and mineral salt
Phloem made of ?
companion cell and sieve tube
What presence in sieve tubes
cytoplasm
