Meristems are areas of cell division that are found at the tip of the stem and just behind the tip of the root of a plant. They provide the cells that are needed in plants to produce height. They also aid secondary stem growth by forming additional cells to increase width.

Define the difference between a primary and secondary cell?

Cell culture is the complex process by which cells are grown under controlled conditions. The growth of explants taken directly form the living organism (e.g. biopsy material) is also known as primary cell culture. The culture consists of mixed population of cell types. Frequently the some of the cells may survive without proliferating and will therefore be lost in the increasing population of those which are able to multiply in the conditions supplied in vitro. Cells from explants may sometimes be converted to cell lines by passage. These may continue to proliferate for a number of cell generations. In some instances the primary cells are fused with so-called immortal (cancer) cells to produce a hybridoma line. Many of the explanted cells will only survive for one or a few passages before dying.


Why do you think is industry classified into three level define the levels given an example of each?

Industry is classified into three levels—primary, secondary, and tertiary—to better understand the nature of economic activities and their contributions to the economy. The primary level involves the extraction of raw materials, such as agriculture or mining; for example, farming wheat. The secondary level focuses on manufacturing and processing these raw materials into finished goods, like a factory producing bread from the wheat. The tertiary level encompasses services that support the economy, such as retail or healthcare, exemplified by a grocery store selling the bread to consumers.

What is no of turns in winding of secondry side of Trasformer when the input is 11KVA and output is 430V?

Turns ratio will define the change in voltage from primary to secondary. What you have supplied is not enough information - you have 1 voltage, and a power value (Killovoltamperes = KVA), which is clearly not enough to answer the equation: N1/N2 = V1/V2, where N1 is the primary side turns, N2 is the secondary, V1 is primary, and V2 is secondary voltage.
