Answer:
Spore
Explanation:
In the process of sexual reproduction, specialized haploid cells from two organisms, which can be called the (+) and (−) mating types, come together to produce a diploid zygote. The zygote after then will go through meiosis to produce four haploid cells termed spores. The spore, houses a new genetic combination from two parents with its capability to be dormant for varying time range.
Plants possesses a life cycle that switches between a multicellular haploid organism and a multicellular diploid organism. Take the ferns for example, both the haploid and diploid plant phases are free-living. The diploid plant is known as a sporophyte due to its ability to form haploid spores by meiosis. The spores grow into a multicellular, haploid plants termed gametophytes since they can have gametes. The gametes of two individuals will come together to produce a diploid zygote that is the sporophyte. The attached image 1 explains more on this.
Fungi, take for instance black bread mold (Rhizopus nigricans), possess haploid-dominant life cycles. The haploid multicellular stage give rise to specialized haploid cells by mitosis that come together to produce a diploid zygote. The zygote pass through meiosis to form haploid spores. Each spore will lead to a multicellular haploid organism by mitosis. The attached image 2 explains more on this.
In addition to air and
water, our body constantly needs regular inflow of food, which provides the
energy reserves necessary for movement, breathing, thermoregulation, heart,
blood circulation and brain activity. In the process of digestion of food
decays to individual glucose molecules which then fall through the intestinal
wall into the bloodstream. With blood flow glucose transported to the liver,
where it is filtered and delayed in reserve. The pituitary gland supplies the
pancreas and thyroid glands signal to the release of hormones that cause the
liver to throw out the accumulated glucose in the bloodstream, and then
delivers it to the blood to the organs and muscles that are in need of it. Having achieved the
desired body glucose molecules penetrate into the cells, where it is converted
into a source of energy that is available for use by cells. Thus, the process
of continuous energy supply agencies depends on the level of glucose in the
blood.
