Explanation: 

Detailed explanation-1: -There are three different types of wood grains depending on the way to cut and slice the wood; flat grain(F), straight grain(S), and curly grain(C).

Detailed explanation-2: -Wood grain refers to the arrangement of a wood’s fibres resulting from the growth of a tree. When the tree is cut, these fibres reveal a visual pattern of relatively darker and lighter wood, commonly known as the grain or-more accurately-the ‘figure’. Wood grain also affects the texture of a piece of sawn timber.

Detailed explanation-3: -The types of wood can be sorted in to three main categories – Softwood, Hardwood and Engineered Wood. Contrary to popular belief, Softwoods are not necessarily soft and neither are Hardwoods hard.

Detailed explanation-4: -The grain refers to the wood fibers relative to the length of the tree on the faces and edges of a piece of timber. Texture is the relative size and variations of the elements. Figure refers to the pattern on a board caused by the arrangement of the different elements and the nature of the grain [14].
