What feature of cell theory is best demonstrated in the image

B. Cells are the basic units of structure and make up tissues.

Explanation:

According to the cell theory, cells can be described as building blocks of an organism. All living things are made up of cells. All cells are made up of former living cells. The cell theory discarded the previous excepted theory of existence of cells from non- living things.

The image shows that in multicellular organisms like plants, different cells are present. Cells of a similar type combine to make tissues.

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
