INTRODUCTION TO MODULE

Question 1

PHYSIOLOGY

Answer 1

the branch of biology that deals with the functions and activities of biological organisms and their parts

Question 2

PLANT ECOPHYSIOLOGY

Answer 2

the way plants work in relationship with their environment
= plant behaviour?

Question 3

BIOTIC interaction

Answer 3

interaction with another living organism

Question 4

ABIOTIC interation

Answer 4

any other type of environmental interaction

Question 5

STRESS

Answer 5

> adverse force or influence that tends to inhibit normal systems from functioning optimally
any external constraints that limits fitness/productivity below the genetic potential of the plant

Question 6

The effect of heat on plants depends on:

Answer 6

> plant species
plant age
plant tissue
biological process
other environmental conditions (e.g. water availability)
duration of heat
time of day

Question 7

STRAIN

Answer 7

detrimental effect of stress on plant physiology

Question 8

STRATEGIES TO SURVIVE and thrive in a stressful environment

Answer 8

not be around when the stress occurs = ESCAPE the stress
prevent the stress from generating a strain = AVOID the stress
repair/ minimise the damages caused by the strain = TOLERATE the stress

Question 9

How is stress resistance studied?

Answer 9

PHENOLOGY: study of periodic biological events like flowering and germination
> morphological level
> cellular level
> molecular level
