<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:
Both animal and plant cells have these components: Cell membrane – this surrounds the cell and allows nutrients to enter and waste to leave it. Nucleus – this controls what happens in the cell. It contains DNA, the genetic information that cells need to grow and reproduce.
Answer:
capillaries:carry blood away from the body and exchange nutrients waste and oxygen with tissues at the cellular level.
veins:are blood vessels that bring blood back to the heart and drain blood from organs and limbs
