Earlier natural manure was used for plant growth and better yield.However with advancements in agricultural technology and research the elements responsible for growth, yield etc was found to be in the basic three elements-NPK (nitrogen,Phosphorus&Potassium).These elements as nitrates , sulphates & phosphates were used .The other micro nutrients like iron,sulphur etc were also traced to plant development over time.
Meristems is the specific areas where plant growth occurs.
CO2
The dependent variable is what changes. For example, if you are growing a plant, the growth of the plant depends on the amount of light it is given. The growth of the plant is the dependent variable.

tissue plant growth is the growth of small organism plant and it is used by growing it in a test tube
The tissue that is responsible for a plant's unceasing growth is the meristematic tissue. It is also known as growing tip and is located in the buds. It contains undifferentiated cells that promote growth.
meristematic tissue (:
they have specialized tissue called growth tissue.
Plant tissue systems fall into one of two general types: meristematic tissue and permanent (or non-meristematic) tissue. Cells of the meristematic tissue are found in meristems, which are plant regions of continuous cell division and growth.

The most distinctive cells found in xylem are the tracheary elements, that is tracheids and vessel elements. However, the xylem is a complex tissue of plants, which means that it includes more than one type of cell. This is why it is a tissue not a cell.
Meristematic tissue is the only plant tissue that produces new cells in mitosis.
Meristematic tissue (vascular cambium) produces secondary growth. In plant stems, this serves to increase the diameter, and it forms between the primary xylem and phloem.
