The lag phase is described with minimized or no uptake of water after the previous imbibition. The water that is imbibed in the first phase is crucial to the processes of physiology that takes place in the second phase. The third phase is the radical protrusion (Vysot︠s︡kiĭ, Kornilova & Smirnov, 2009). The effect of up taking water is the cell enlargement which is characterized by the cell division. The small root enlargement helps in weakening the walls of cells and breaks through the coat of seed.

It is evident, that water plays a crucial factor in the germination phases. Water is among the main environmental factors that affect the seed germination. In some cases, water is a single factor that will limit if or not a seed is going to germinate. In the case of marigolds, a given temperature needs to break the dormancy for the marigolds to start the first stage of taking up water. The seeds of marigolds take in water in three staged, each is characterized by the amount of water absorbed and the impact it will have on the amount that is absorbed and the impact it has on the seed itself.

The hypothesis if water is given to the marigold seed, the seed will germinate and later grow compared to the seed having no water was supported. From the observation, only three of the seeds without water grew. In the controlled group 8 of the 10 seeds germinated and later grew. The average growth for the controlled group was 4.37 while the average growth for the experimental group was 0.38. Therefore, given water is needed for a seed to grow. The water is important in chemical reactions since it is photosynthesis raw material.

Without water no growth can take place and he plants will lack the energy to carry out chemical reactions. 9 of the planted seeds did not grow at all. 2 from the control group and 7 from the experimental group. It is no surprise that some of the marigold seeds did not germinate from the experimental
