The magmatic rock or the igneous rock refers to one of the three prime kinds of rock, the others are metamorphic and sedimentary rocks. The formation of igneous rock takes place via the cooling and solidification of lava or magma.
Of the igneous rocks, the intrusive igneous rocks form the major portion of the igneous rocks and are produced from the magma, which solidifies and cools inside the planet's crust, enclosed by pre-existing rocks. The cooling of the magma takes place gradually, and as a consequence, these rocks are coarse-grained.
D. CO₂ is needed to produce sugars in the Calvin cycle.
Explanation:
We know that CO₂ is the prime element for photosynthesis.
CO₂ is the only source that supplies carbons in this process. With the help of CO₂, water, light, minerals, and chlorophyll, six-carbon glucose is formed.
This glucose is converted to starch and is stored in fruits or in the parts of plants for further use.
