A leaf is a highly organized manufacturing facility – an organ constructed of numerous types of specialized cells, each of which has its own responsibilities. The product of the manufacturing facility is no less than the food which supports nearly all life in the world.
The scientific approach that aims to apply genetic methods to deal with the maintenance, sustainability, and restoration of biodiversity is called genetic conservation.
The estuary is a coastal water body formed where the sea and river water overlap and blend with each other therefore they are also considered as transition zones or ecotones.
Genetic engineering is the advanced process of modifying or manipulating genes by either insertion or removal, usually outside the organism’s normal reproductive process.
The thick and swollen modified stem which grows under the ground and lacks green color due to their underground nature with a large amount of stored food is called the underground stem.
The structure of a plant that develops into the seed upon fertilization is called ovules. It is the precursor to seeds. Basically, these are immature seeds consisting of integuments, nucellus, and female gametophyte or reproductive cells.
The event of rapid and repeated mitotic division of cells to form numerous nucleated cells is called cleavage.
Sclerenchyma is a specialized tissue, adapted to hold up against both compressive and tensile stresses in plants. Sclerenchyma cell forms may be separated into fibres, connected with phloem, xylem, and various other cells; and sclereids or varied kinds.
The concept of the operon was presented by Jacob and Monod in 1961. In microorganisms and archaea bacteria, structural proteins with associated features are usually inscribed together within the genome in a block called an operon.
The portion of the primary axis of the plant which develops from the plumule is called the stem. The stem has nodes and internodes.
