Description
Crop improvement can be defined as
i. An art, a science, and technology of improving the genetic makeup of plants in relation to their economic use for the mankind.
ii. The art and science of improving the heredity of plants for the benefit of mankind.
iii. Science of changing and improving the heredity of plants
2. Genetics
The study of heredity and the variation of inherited characteristics, the science of genetics enables plant breeders to predict to varying extents the outcome of genetic manipulation of plants. The techniques and methods employed in breeding are determined based on the genetics of the trait of interest, regarding, for example, the number of genes coding for it and gene action. For example, the size of the segregating population to generate in order to have a chance of observing that unique plant with the desired combination of genes depends on the number of genes involved in the expression of the desired trait.

EXCHANGE OF RESPIRATORY GASES
Trending!
Active body cells require lots of oxygen for energy production in aerobic respiration as we learnt in Lecture IV. A major by product of aerobic respiration is carbon dioxide. Carbon dioxide dissolves in water to form carbonic acid and hence disturbs acid base balance in the body. Accumulation of carbon dioxide is therefore toxic to the cells as it may cause acidosis. Living cells have mechanisms of intake of oxygen and elimination of carbon dioxide. The two gases are known as respiratory gases. In small organisms such as protozoans the body surface provides an adequate surface area for the exchange of respiratory gases by diffusion. In mammals and other higher animals there are specialized systems for exchange of respiratory gases.

EMBRYONIC GROWTH AND METAMORPHOSES IN INSECTS
Trending!
Once an insect hatches from the egg it is usually
able to survive on its own, but it is small, wingless,
and sexually immature. Its primary role in life is to
eat and grow. If it survives, it will periodically
outgrow and replace its exoskeleton (a process known as moulting).
• In many species, there are other physical changes that also occur as the insect gets older (e.g., growth of wings and development of external genitalia)

Subphylum Uniramia
Trending!
Five classes of Uniramia are recognized:
1. Class Diplopoda (millipedes)
2. Class Chilopoda (centipedes)
3. Class Symphyla (sympylids)
4. Class Pauropoda (pauropods)
5. Class Insecta (insects)
Centipedes, millipedes, symphylids and pauropods are collectively called myriapodous arthropods (Myriapods). All have long trunks with many segments and appendages, most of which are walking legs.

Insect Hormones
Trending!
Insect Hormones
• A hormone is a chemical signal sent from cells in one
part of an organism to cells in another part (or parts) of
the same individual. They are often regarded as chemical messengers.
• Typically produced in very small quantities, but cause profound changes in their target cells
• Their effect may be stimulatory or inhibitory
• In some cases, a single hormone may have multiple targets and cause different effects in each target
• Examples of processes controlled by hormones include moulting, metamorphosis, oocyte development (vitellogenesis), colour change and diurnal rhythms of activity
