The concept would be crystallization. As magma cools inside or outside of the earth it crystallizes into an igneous rock. Intrusive (formed inside crust) igneous rocks are typically more course grained and contain many different noticeable minerals (for example, granite).

<h2>Rhizoids absorb water and nutrients from the surrounding soil.
</h2>
Explanation:
Rhizoids are primitive root like structure in lower plants like bryophytes and sin fungi. Rhizoids are usually unicellular. However many plants exhibit multicellularity. Rhizoids functions as the roots in these plant,by absorbing water and nutrient from the surrounding soil. They may contain enzymes which helps in extracellular digestion in orgsnidm which have saprotrophic mode of nutrition.Rhizoids provide a little anchorage to the substratum.
