<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.
Answer:Una célula pasa por cuatro etapas a lo largo de su vida, que son: el nacimiento, el crecimiento, la diferenciación y la reproducción o muerte celular.
El proceso por el cual nace una célula a partir de otra preexistente se denomina división celular. El mecanismo que da origen a un nuevo individuo, en organismos unicelulares, es decir, organismos formados por una sola célula, se produce para aumentar el tamaño de su población, mientras que en organismos pluricelulares, este proceso funciona para aumentar el número de células y el reemplazo de células que se encuentren dañadas o muertas.
El ciclo celular se define como el conjunto de transformaciones que sufren las células para generar dos células hijas.
Este ciclo está formado por tres fases: la interfase, la mitosis y la ciclo

The scientist can conclude that the plants that were used in this experiment contained both a dominant and recessive allele. That the plants were hybrids which causes the off springs to have a 3:1 ratio.
