The water, warmed by the sun, turns into vapor (evaporates), and passes out through thousands of tiny pores (stomata) mostly on the underside of the leaf surface. This is transpiration. It has two main functions: cooling the plant and pumping water and minerals to the leaves for photosynthesis.
An action potential involves the transfer SODIUM and POTASSIUM ions across an axon's membrane.
During depolarization, when the ion channels open, they allow the influx of sodium ions into the cell, thus changing the electro-chemical gradient of the cell, in order to counter balance this, potassium ions will be allowed to flow out of the cell.<span />
Answer:
True breeding
Explanation:
True breeding is a breeding in which parents produce the offspring which carry same phenotype.
The parents in true breeding are homozygous for every trait.
<u>True breeding occurs in the plants when the plants produce offspring of same variety only when self pollination takes place. </u>
<u>For example, if a plant has purple flowers will produce only seeds which will grow into plants which have purple flowers.</u>
It's Gametes Sexual reproduction is the union of male and female gametes to form a fertilized egg, or zygote. The resulting offspring inherit one half of their traits from each parent.
