Which exposed wood will decay faster?
Correct answer: A. Sapwood
- A. Sapwood
- B. Softwood
- C. Wood with lot of fibres
- D. Heartwood
Explanation
Sapwood will decay faster. Sap wood is less durable because it is susceptible to attack by pathogens and insects. The outer light-colored functional wood which contains living cells is called sapwood. It is prone to attack by pathogens and insects. So it easily undergoes decomposition, when exposed to insects and pathogens

About Growth and Development
Embryonic development covers fertilization, cleavage, formation of the blastula and gastrula, germ layers, organ formation and differentiation. Regeneration describes the replacement of lost tissues or body parts, whereas ageing involves gradual cellular and physiological changes linked to reduced repair, altered metabolism and declining organ function.
