Difference between subsistence farming and commercial farming

Explanation:

Subsistence farming is done basically to feed the farmers family itself. It has little or no profit.

Commercial farming is done with the intent of profit, where cash crops are sown.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

cell regulation is conducted by special proteins.
