What Is Apical Meristem and What Does It Do? Apical meristem is found at the apices, or tips of the plant, both the tip of the shoot and the root, and is a region of actively dividing cells. The definition is easy to remember when you break it down. An apex (plural: apices) is the tip, the very end, of something. You can think of 'meristem' as any kind of plant tissue that is made of cells that don't know what they want to be when they grow up, like happy, 'merry' children.
A metamorphic rock turns into magma by being exposed to the heat and pressure inside earth. The rock then becomes a flowing form of rock, called magma. It is then deposited back into its origin, a magma chamber, where it is spurted out as lava only to become an igneous rock again. #2. Well, first of all, metamorphic rocks turn into magma from heat inside earth. It gets so hot that the metamorphic rock turns into its flowing form. It then makes its way into the mantle and back out again as lava. The rock cycle is then repeated. A metamorphic rock turns into magma when its plate is being subducted beneath another plate. It is then exposed to the heat inside the mantle. In the mantle, it is melted into magma. The magma is now, what used to be a metamorphic rock.
When the magma cools it solidifies and forms rocks, the type of rock formed depends on the chemical composition of the magma and how rapidly the magma cools. Magma that reaches the surface to become lava cools rapidly resulting in rocks with small crystals such as basalt.olcanism is the phenomenon of eruption of molten rock (magma) onto the surface of the Earth or a solid-surface planet or moon, where lava, pyroclastics and volcanic gases erupt through a break in the surface called a vent.
