Your Ad Here	Lepidoptera. Butterflies, moths. Order of endopterygote insects. Two pairs of large wings covered with scales; larva a caterpillar with prolegs on abdomen. Adults feed nectar of flowers using a highly specialized, often coilable, proboscis; Larvae usually feed on plants. Lepidosiren. The south American lungfish (member of Depnoi). Lepto. Denoting small thim. Leptocephalus. Oceanic larva of European eel. Migrates more than 2000 miles across Atlantic from breeding-ground of eels near West Indies to reach European fresh waters, where becomes adult, Quite transparent. Leptotene. Stage in early prophase of first division of meiosis in which the chromosomes appear as a tangles mass of very slender threads bearing bead-like structures, the chromosomes, along their length.
Leptosporangiate. (Of sporangia in vascular plants), arising from a single parent cell and possessing a wall of one layer of cells. Spore Production low in comparison with eusporangiate type. Lesion. A localized area of diseased tissue. Lethal gene. Gene which kills individual bearing it. If individuals heterozygous for it is dominant lethal; if only individuals homozygous for it are killed, it is a recessive lethal. Leuco. Denoting white.
Leucocyte. White blood cell. Leucocytosis. Presence of unusually great number of white blood cells in blood, a response to infection of tissue clamage. Lencosin. A food reserve found in the chrysophyceae. Leydig cells. The cells of the tests that secrete. Testosterone when stimulated by luteenizing Hormone. Liana. A climbing tropical plant with a rope-like stem. Life Cycle. Progressive series of changes undergone by an organism or lineal succession of organism, from fertilization to the death of that stage producing the gametes which begin an identical series of changes.

Ligament. Strong band of collagen connecting the two bones at a joint. Ligase. An enzyme that catalyses the joining of short molecules into longer ones for example, DNALIGASE. Light. That part of the electromagnetic spectrum which is visible to the human eye between about 400nm (blue) and 770 nm (red). Limnology. The study of fresh waters and their inhabitants. Linguar. (Adj.). Of the tongue.
Your Ad Here	Linkage. The association of a number of characteristics that are inherited together because the genes responsible for them are situated on the same chromosome. Linkage can be broken by crossing over during mitosis, when sections of chromosomes are exchanged and new combinations of genes are produced. Lip. Denoting fat. Lipin. A complex fat containing nitrogen and frequently phosphorous or sulphur. Lipogenesis. The formation of fats from non-fatty sources. Lipoid. Any substances with fat like properties including true fats, Steroids and Lipuis. Liquid feeder. Any organism that feeds exclusively on liquid such as a mosquito.

Lipose. The enzyme that breaks down fat into fatty acids and glycerol. The main source is the pancreatic juice.

Liver. Gland whose duct into gut, usually with digestive function. Not homologous in different phyla. Liver of vertebrates has many functions, e.g., secretion of bile; storage of glycogen synthesis of plasma albumin.

Liver-Fluke. Of sheep, cattle, etc., fluke which lives in bile ducts and causes liver-rot disease which leads to great losses. Common in wet meadows where the intermediate host, water snail, flourishes and infects the pastures with cercaria larvae.

Lizard. Any member of the replittian order lacertika, the majority of which posses a long scaly body and tail and four obvious limbs.
