Wind dispersion of reproductive cells allowed in seedplants to colonize
land away from water supplies. If water is needed to
passively transport gametes to each other and protect them from desiccation
plants were limited to densely inhabited space near water sources.
Bryophytes & ferns (seedless) are dependent on moist environments
for reproduction but the first seed plants developed an alternate
delivery system allowing independence from water- assisted reproduction.
Conifers produce pollen that can survive by carrying water and
nutrients along. Wind can now carry these male gametophytes to female
gametophytes under the scales of a cone. Fertilization produced a
diploid seed. The seed is protected and can survive dry conditions for a
period of time before growing. Pollen and seeds transferred a conifer’s
water dependence for their reproduction to wind dependence. </span>
Hey friend!
You stuck?
The organelle that sends out microtubules that connect to DNA during Metaphase are called centrioles. The connect to the DNA during metaphase, during that process they determine the position of the nucleus.
Hope this helps! :)
It would be called symbiosis
Answer:
mitosis results in two identical daughter cells ..hope this helped!
Explanation: a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells.
It helps with population and reproduction.
