Answer:
Magnesium, calcium, phosphorous, sulfur these are essential nutrients for plants. These are required in trace quantity but are very important for plant life. Point A. will be correct answer.
Explanation:
As in B. starch n cellulose are composed of only carbon, oxygen and hydrogen.
As in C. These elements are not required on special occasion but are necessary throughout plant life.
As in D. C H N O is the primary component plants need but these secondary nutrients are equally necessary for growth n structure of plant.
<u><em>So answer A. Is the correct option.</em></u>
Calcium plays the most important role in structure formation of plants. Also act as messenger molecule in signaling. Deficiency of calcium caused wilting , weakened stem and ultimately death of plant.
Magnesium is the key element in chlorophyll molecule. It is necessary for chlorophyll formation.
Sulfur is another very important element in plant life, it is necessary for protein synthesis in plants.
Phosphorous plays an important role in process of cell devision , photosynthesis and respiration.
Potassium is very crucial in gaseous exchange ,it operates the opening and closing of stomata.

An example of stewardship is the responsibility of managing the staff of an estate. An example of stewardship is the act of making wise use of the natural resources provided by the earth.
Answer:
The correct labels of the three planes are -
a. axial or transverse plane.
b. sagittal plane
c.. coronal plane
Explanation:
The human body can be divided into three planes on the basis of anatomy - the sagittal plane, the coronal plane, and the transverse plane
A sagittal plane is a longitudinal plane that divides the human body in the left and right parts.
A coronal plane is an anatomical plane that divides the body vertically into the back and front, ventral or dorsal (to be more specific).
An Axial or transverse plane, it is the plane that divides in the upper part of the body and lower part of the body.
Thus, the correct answer is -
a. axial or transverse plane.
b. sagittal plane
c. coronal plane
