The answer of the first question is double fertilization !!! I don't get the second question so.... comment if you have that question !!!
Ans.
Hormones are regulatory substances synthesized by various plants and animals and play role in proper growth, development, and maintain homeostasis. Hormones are released by signalling cells and show their actions after binding to specific receptors present on the surface or inside of the target cell.
Hormones, for which receptors are present inside the cells (in cytosol or nucleus) should be hydrophobic in nature. This is because plasma membrane is made up lipid molecules and small, hydrophobic, uncharged molecules can easily pass through this. For example, cortisol, estrogen, and progesterone hormones are lipid-derivatives and receptors for these hormones are present inside the cells.
The gardener should address the measurements he needs to make so that planting information is clear, and that the roots are spaced to grow.
<h3>How to calculate amount of landscaping plants?</h3>
just divide the area of the bed by the area occupied by the seedling and we will have the total amount of seedlings to be used. In this way, we also understand that the area occupied by the seedling is equal to the spacing between seedlings raised to the square.
<h3>How to calculate the spacing between plants?</h3>
If we plant with a spacing of 0.60 meters, the number of seeds per meter will be calculated as follows: Being 1 hectare = 10,000 square meters and the spacing between rows of 0.60 m, we have the equivalent of a range of 0, 60 meters by 16,667 linear meters (10,000 divided by 0.60).
With this information, we can conclude that the area occupied by the seedling is equal to the spacing between seedlings raised to the square.
