Answer #1
  • Pine cones can be differentiated based on the diameter of the cone .
  • If the diameter is small then the age of cone will be 1 year . If the diameter is large then age might be above 2 years.
  • The resin content in the younger cone will be more compared to older cones.
  • The weight of the pine cone increases as its proceeds through the age . That is 1 year will be lighter and cones that are above 2 years will be heavier.
  • This is mainly because of accumulation of nutrition in the cones.
  • The germination effects are greater for pine cones that are large . So 2 year cones have greater germination percentage than 1 year cone.
  • So, as the age of the cone progresses the size, diameter , germination capacity and nutrition of the cone increases .

  • Here B is one year cone . G is more than 2 years.
