The contamination can be defined as growth of undesired microbes in the petri dishes or tubes which is no longer useful for the experiment.

Answer:. have chloroplasts and a cell wall
Explanation:All living organisms are made up of cells.some organism are made up of one cell (Unicellular) and other organism are made up of many cells(multicellular).
Cells are made up of organelles and the organelles present in a cell differ in animals cells and plant cells.
A feature that animals cells have which plant cell do not have is the presence of centrioles.
Features that plant cell have which animals cells do not have are the presence of chloroplast ,vacuole and cell walls.
Animals do not produce their food but plants do.Green Plants produce their food through chloroplast,which contains chlorophyll.
Plants has cells walls which is rigid and made up of cellulose,lignin and pectin.this rigid structure of the cell wall contributes to the rigidity of plants stems and roots.
Option A is incorrect because plant and animal cells have mitochondria.
Option B is incorrect because plants cells have both plasma membrane and cell walls.the cell wall surrounds the plasma membrane.
Option C is incorrect because plants contains Golgi apparatus and vacuole
