Is the texture of an igneous rock determined by the composition of the magma?

No. The texture is determined by the amount of time the magma had to cool and solidify. Slow cooling magmas produce larger crystals and therefore have a coarse grained texture. Quick cooling magma or lava produce small crystals and a fine grained rock texture.

They occupy a complicated sequence from "basic" (relatively low silica: basalt) to "acid" (high silica: granite), and are further complicated by local accessory mineral content.

What makes a igneous rock an igneous rock?
An igneous rock is formed through the solidification of molten material, either magma or lava, that cools and crystallizes. This process occurs below or on the Earth's surface. The mineral composition and texture of igneous rocks vary depending on factors such as the cooling rate and the composition of the molten material.
What are the factors that controls most texture in igneous rocks?
magma or lava controls most texture in igneous rock
What is the texture of an igneous rock from magma that cools in two stages?
It's texture is porphyritic
What is determined by how magma cools and where it cools?
Its texture.
Igneous rocks are formed when magma does what?
The Igneous rock formed when magma cools are; 1. Extrusive (Volcanic) Igneous Rock; which are igneous rocks formed when magma cools outside the earths crust. The texture of of extrusive igneous rock is fine grained. 2. Intrusive (Plutonic) Igneous Rock; these are igneous rocks formed by gradual cooling of magma within the earths crust. The texture is coarse grained.
What factors can effect the texture of a igneous rock?
The texture is determined by the rate it takes the molten to cool to form the rock.
What characteristics determines the chemical composition of an igneous rock?
An igneous rock is any crystalline or glassy rock that forms from cooling of a magma. Color and texture help determine the chemical composition of the rock.

Its texture.
How do igneous rocks for?
I think you mean form, so, they are cooled magma and are classified 3 ways: mineral composition (aka color) texture, or if they are made internally or externally
What kind of rock forms when hot liquid rock or magma cools?
Extrusive igneous rocks. The type of extrusive igneous rock is determined by the composition of the lava.

What determines the color of a igneous rock?
The composition of the magma or lava that it cools from.
What factors affect the texture of igneous rock?
the length of time the magma had to cool
