Describe the differences between the sporophyte and gametophyte generations of seedless tracheophyte plants and be sure to discu
kykrilka [37]

Answer and Explanation:

Tracheophyte plants, also known as vascular plants, are those that possess a supportive tissue that can also conduct fluids -The Xileme- and another tissue that conducts nutritious elements produced by photosynthesis -The Phloem-. These plants have a root (basically underground), a stem (aerial), and leaves. All of them together form the corm. And the corm counts with these vascular tissues to which we referred before.  

There are different types of Tracheophyte plants, some of them produce seeds to reproduce and disperse -Spermatophyta-  and some others reproduce and disperse by spores -Pteridophyta-. This last seedless group corresponds to ferns and other similar plants.

Pteridophytes characterizes for having a sporophyte that has stems with leaves and a root. It also has primitive xylem composed by tracheids and phloem, both of them formed by vascular bundles located in a central cylinder.

Spores are its dispersion units and are responsible for colonizing new areas. They also constitute the resistance units under extremely unfavorable conditions.  

Their life cycle is composed of the asexual phase (sporophytic phase) and the sexual phase (gametophytic).  

  • The <u>sporophyte</u>, the dominant asexual generation, it is a perennial and diploid structure. Its aerial part might disappear during unfavorable seasons, but it reappears during spring or summer.  The sporophyte is in charge of asexual reproduction
  • The<u> gametophyte</u>, instead, is and haploid structure, ephemeral and must be in the water for its survival, and for sexual reproduction to be successful. In the presence of water, masculine gametophyte -antherozoids- are released and they swim to the archegonium to meet the ovocell. Antherozoids can swim because they have flagella. After fertilization, a new sporophyte is produced.

Why does the oxygen atom in a water molecule have a negative charge
rodikova [14]

In water molecule the electrons between the oxygen and the hydrogen are shared, but the sharing is not equal. Oxygen pulls electrons slightly towards itself. Therefore, the electrons are more near the oxygen, making that part of molecule(oxygen part) slightly negative. Since the electrons are not near the hydrogen so, that part of the molecule is slightly positive.

pishuonlain [190]
<h2>Cannon -Bard theory</h2>

Explanation:

  • Alone in the woods, Pedro hears a noise. He thinks he sees a bear coming toward him. His heart starts pounding and then, a moment later, he realizes how frightened he is. This sequence of events is BEST explained by the <u>Cannon-Bard t</u>heory of emotion.

According to Cannon-Bard theory, all the emotional expressions occur due to the stimulation of hypothalamic structures present in brain. This theory also states that feeling and physiological effects of an emotional stimuli occurs simultaneously.

Here, James thinks that a bear is coming, this is a stimulus. His heart starts pounding that is the physiological effect of the stimulus and the next moment he feels frightened which is a feeling.

So we conclude that in this case, the physiological effect and feeling of emotion occurred simultaneously. So these sequence of events is best explained  by Cannon-Bard's theory.
