The document discusses the application of different types of radiation in plant science, focusing on their definitions and effects on plant growth and development. It categorizes radiation into ionizing and non-ionizing types, detailing how ultraviolet radiation can negatively impact seed growth, plant cell viability, and reproduction. References are provided for further reading on the topic.

6. TYPES OF RADIATION
1) Ionizing radiations.
2) Non ionizing radiations.
1. IONIZING RADIATION :-
Higher energy electromagnetic
waves (gamma) or heavy particles (beta
and alpha).

8. High enough energy to pull electron from
orbit.
 E.G :-
Alpha particles.
Beta particles.
Gamma rays.
2. NON IONIZING RADIATIONS :-
Longer wavelength and low energy.
Not enough energy to pull electron from
orbit.
Lower energy electro magenetic waves.

9. E.G:-
oUltraviolet radiations (UV).
o Visible light.
oInfrared radiation.
o Microwave radiation.
o Radio frequency radiation.

11. EFFECTS OF RADIATION ON PLANT
GROWTH & DEVELOPMENT
Prevents seed growth ultraviolet
radiation effects plant growth and
development in many ways.
First it gradually stops seed growth and
depended on the how much radiation is
released.

12. The stomata is a small air hole with in a
plant leaf that also controls water levels.
If the stomata is unable to open for a long
period of time ,the growth of the plant.
Damages plant cells.
The cells of living organism are also
damaged and killed by ultraviolet radiation.
Cells contain responsible for plant
reproduction.if the needed for
photosynthesis and normal plant growth.

13. DAMAGES PLANT CELLS
 The cells of living organism are also
damaged and killed by ultraviolet radiation.
 What allows plants to grow is the division
and expansion of cells as they take up
water.
 Cells contain chromosomes, the genetic
material responsible for plant reproduction.
 If the cell is overly damaged by radiation,
then reproduction is hindered.
