Relate the development of plant needles to the occurrence of mutations.

xxMikexx [17]

<h2>Development of Plant Needles</h2>

Explanation:

Seed of pitch pine treated with colchicine delivered tetraploid seedlings which had thick and sporadic needles and less fortunate tallness and diameter growth than ordinary seedlings.

In test of colchicine-initiated polyploidy in pines, researcher found that a significant number of the polyploid plants returned to a diploid development in light of the fact that the polyploid cells partitioned at a more slow rate and were overwhelmed by the more quickly developing diploid cells which encompassed them.

The primary needles of both diploid and polyploid plants were more effective at low light intensity than secondary needles, and they had lower compensation points.

Jet001 [13]

In the summer the northern hemispher gets the most light and the further north you go or the higher latitude the more daylight you get. The Equator is more half and half. The north pole, the sun never sets.

Winter the further north you go, the more night time you get. Equator is still more or less half and half.
