- XYLEM
5
Q
CHARACTERISTICS OF EPIDERMAL TISSUE
A
- COVERED WITH CUTICLES
6
Q
CHARACTERISTICS OF PARENCHYMA TISSUE
A
- STORES FOOD
- PROVIDES SUPPORT
- CARRIES OUT PHOTOSYNTHESIS
7
Q
CHARACTERISTICS OF COLLENCHYMA TISSUE
A
- PROVIDES MECHANICAL SUPPORT ( NON WOODY PLANTS)
8
Q
CHARACTERISTICS OF SCLERENCHYMA TISSUE
A
- MOST OF CELLS ARE DEAD AT MATURITY
- SIMPLE CELLS WHICH ARE UNIFORMLY THICKENED WITH LIGNIN
- PROVIDE MECHANICAL SUPPORT FOR MATURED PLANTS
9
Q
CHARACTERISTICS OF XYLEM TISSUE
A
- TRANSPORTS WATER AND MINERAL SALTS
- CELL WALL IS THICKENED WITH LIGNIN
10
Q
CHARACTERISTICS OF PHLOEM TISSUE
A
- CONSISTS OF SIEVE TUBES AND COMPANION CELLS
11
Q
FUNCTION OF SIEVE TUBES
A
- TRANSPORTS ORGANIC MATERIAL FROM LEAVES TO THE PLANT
12
Q
FUNCTIONOF COMPANION CELL
A
- PROVIDE ENERGY AND NUTRIENTS OF SIEVE TUBES
13
Q
FUNCTION OF ROOT HAIR CELL
A
- EFFICIENT ABSORBTION OF WATER FROM SOIL
14
Q
FUNCTIONS OF GUARD CELLS
A
- CONTROL OPENINGF STOMA FOER EFFICIENT GASEOUS EXCHANGE
15
Q
FUNCTIONS OF PALISADE MESOPHYLL CELL
A
- FORMED CLOSELY AND VERTICALLY TO MAXIMISE THE AMOUNT OF SUNLIGHT THAT REACHES THE CHLOROPLAST FOR PHOTOSYNTHESIS
