Explanation:

The oldest fossil evidence of seed plants is of Late Devonian age, and they appear to have evolved out of an earlier group known as the progymnosperms. These early seed plants ranged from trees to small, rambling shrubs; like most early progymnosperms, they were woody plants with fern-like foliage.

Soils contain small or trace amounts of many minerals, including the chemical elements phosphorus, calcium, potassium, magnesium

serg [7]

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.
