Question

Пилкові зерна сосни поширюються на значні відстані завдяки?​

Answer 1

Ответ:

Объяснение: Половое размножение имеет огромное биологическое значение. Преимущество его перед бесполым размножением заключается в том, что оно создаёт возможность комбинации генетических признаков обоих родителей.

Answer 2

Spread of Pine Pollen Grains

Pine pollen grains are spread over significant distances due to wind pollination. Pine trees rely on the wind to carry their lightweight pollen grains to female cones for fertilization. This method allows the pollen to travel far and wide, increasing the chances of successful pollination and genetic diversity within the species [[1]].

Additionally, the structure of pine pollen grains contributes to their ability to travel long distances. The outer layer of the pollen grain is made of a tough material called sporopollenin, which helps protect the genetic material inside and allows the pollen to withstand the rigors of wind dispersal [[2]].

In summary, the spread of pine pollen grains over significant distances is primarily facilitated by wind pollination and the unique structure of the pollen grains themselves.
