Abstract
The term larva applies to the young hatchling which varies from the grown up adult in possessing organs not present in the adult such as sex glands and associated parts. Insect development is of four types namely Ametabolous, Paurometabolous, Hemimetabolous and Holometabolous. The larvae appear in variety of forms and are termed as caterpillars, grubs or maggots in different insects groups. The larval development consists of series of stages in which each stage is separated from the next by a molt. It’s a complex process involving hormones, proteins and enzymes. Insects grow in increments. The molting is the process through which insects can routinely cast off their exoskeleton during specific times in their life cycle. The insect form in between two subsequent molts is termed as instar. The number of instars varies from 3 to 40 in different insect orders depending on the surrounding environmental and other conditions such as inheritance, sex, food quality and quantity. The larvae are categorized into four types namely Protopod larva, Polypod larva, Oligopod larva and Apodous larva.
(a) Cones : Iodopsim :: Rods : Rhodosphin
The photosensitive pigment present in the rods of the retina - Rhodopsin
The photosensitive pigment present in the cones of the retina - Iodopsim
(b) Sound : Ear drum :: Dynamic balance : Semicircular Canals
Ear drum receives the sound in the ear and the dynamic balance of the body is provided by Semicircular Canals.
Nephridia are segmentally arranged coiled tubules formed by the invagination of ectoderm into coelom. Internally they may end blindly into the coelom (protonephridia) or may open into the coelom by a ciliated funnels or nephrostomes (metanephridia). Externally they opens through small apertures called nephridiopores.
An autotroph or primary producer is an organism that produces complex organic compounds (such as carbohydrates, fats, and proteins) using carbon from simple substances such as carbon dioxide,[1] generally using energy from light (photosynthesis) or inorganic chemical reactions (chemosynthesis).[2] Autotrophs do not need a living source of carbon or energy and are the producers in a food chain, such as plants on land or algae in water (in contrast to heterotrophs as consumers of autotrophs or other heterotrophs). Autotrophs can reduce carbon dioxide to make organic compounds for biosynthesis and as stored chemical fuel. Most autotrophs use water as the reducing agent, but some can use other hydrogen compounds such as hydrogen sulfid
Animal starch is known as glycogen. The glucose molecules in the plants are polymerised to form the molecule of starch which is stored in the plant cells as the reserve food. The animals have polymerised glucose stored in the form of glycogen. Glycogen is stored in the hepatic cells in the liver.
Monera (/məˈnɪərə/) (Greek - μονήρης (monḗrēs), "single", "solitary") is a kingdom that contains unicellular organisms with a prokaryotic cell organization (having no nuclear membrane), such as bacteria. They are single-celled organisms with no true nuclear membrane (prokaryotic organisms).
