Endangered plant species and their conservation measure

Based on the survey and exploration as well as herbarium and literature studies, about 1500 species of flowering plants and few hundreds of Pteridophytes, Bryophytes, Lichens and Fungi have been identified as threatened.  Biodiversity andits conservation are now vital environmental issues of international concernas more and more people around the world begin to realise the […]

Classification of Plant Kingdom

Plants are one of the five main groups of living things. These groups are called kingdoms. The plant kingdom includes such living things as grasses, trees, ferns, bushes, and flowers. Botanists, the scientists who study plants, have counted more than 300,000 species (kinds) of plants. Plant Classification: In order to study the billions of different […]

Photosynthesis

Photosynthesis ( photo =light, synthesis-= putting together ) is the process of formation of simple sugars by green plants, some bacteria, and some protistans from water from soil and carbon dioxide from air in presence of sunlight and chlorophyll. Photosynthesis converts light/solar energy into chemical energy, and thus is very important to life. Chemical equation […]

Growth Regulators in Plants

Plants produce chemical compounds, called hormones, that act as chemical signals between cells and tissues in different parts of the plant. Some hormones stimulate growth activity in the plant, while others inhibit growth activity. Because they regulate growth, plant hormones are often called plant growth regulators. There are currently five recognized groups of plant hormones: […]

Deviations From Mendelian Genetics

Exception of law of dominance: Incomplete dominance: In incomplete dominance when a red snapdragon flowered plant is crossed with a white flowered plant an intermediate phenotype appears in the F1 hybrid instead of a parental phenotype. Codominance: Unlike dominance in codominance when a A (I^AI^A) blood group individual mates with B (I^BI^B) blood group individual […]

Terms to be know in Mendelian genetics

Alleles: these are the different forms of a gene. T and t are different alleles of the gene that determine the height of the pea plant. Alleles occupy the same locus or position on chromosomes.  Allelic pair: the combination of two alleles which comprise the gene pair. Autosomal: a locus on any chromosome excluding a […]

Mendelism Genetics

Heredity is passing characteristics from one generation to the next. Genetics is the study of heredity. Gregor Mendel is the “Father of Modern Genetics.” He was an Austrian monk who studied heredity in pea plants. His work was published in 1865. He described “factors”that were passed between generations of plants We now know the factors […]
