<p>Can someone explain gametophyte/sporophyte (plant alternation of generations and, if you feel like it, fungi/protists as well) to me?</p>
<p>gametophyte is the sperm/egg state of the cycle. Basically the gametophyte state reproduces using mitsoses so more n number of chromosomes are being produced. Then the plants/fungi switch to the sporophyte generation which has a 2n number of chromosomes. In this state, the sperm and egg basically fertilize and come together to come to a total of a 2n chromosome and this cycle leads to the sapling and then the three itself.</p>

<p>Favorite: Quite a bit actually, but I particularly enjoy molecular, human systems, and regenerative-based biology</p>
<p>Least: Plants, I suppose</p>

<p>I apologize for skipping over your question. I will provide it in bulleted format for the sake of simplicity:</p>
<p>Protists</p>
<p>[ul] [<em>] Include the widest variety of eukaryotic organisms
[</em>] Consist of single-celled and relatively primitive multicellular organisms
[<em>] May be either heterotrophic (rely on the external surroundings for nourishment) or autotrophic (self-producing, such as photosynthetic beings like euglena)
[</em>] Motile by various means - psudopods (amoeba), cilia (paramecium), flagella (euglena)
[li] Some participate in conjugation (basic form of sexual reproduction)[/ul]</p>[/li]
<p> Fungi </p>
<p>[ul][<em>] Necessary conditions for classification: Heterotrophic and eukaryotic
[</em>] Extracellular digestion via hydrolytic enzymes
[<em>] Decomposers (essential for ecosystem health)
[</em>] Chitin composes the cell walls (a compound present in animal exoskeletons)[/ul]</p>
<p>Since we are on the topic of Protists…</p>
<p>[ul][li]Which is not true of Protists?[/li][list] <a href=“A”></a> Some are autotrophs
<a href=“B”></a> Some are heterotrophs
<a href=“C”></a> An example is euglena
<a href=“D”></a> They do not have internal membranes
<a href=“E”>*</a> Some have flagella; some move by flagella [/ul][/list]</p>
<p>[ul][li]Which of the following are best characterized as being eukaryotic, heterotrophic, and having cell walls made of chitin?[/li][list]<a href=“A”></a> plants
<a href=“B”></a> animals
<a href=“C”></a> archaea
<a href=“D”></a> fungi
<a href=“E”>*</a> viruses [/ul][/list]</p>
<p>First is (D) many protists have plastids and mitochrondria and all that other good stuff (scientific lingo)</p>
<p>Second is (D) Fungi</p>
<p>not plants they are autotrophic w/ cellulose
aminals don’t have cell walls
archae are prokaryotic
Viruses aren’t life</p>
<p>We have exactly 2 months left till the test…</p>
<p>Do you guys have a set of flashcards that you study from? If yes, which ones are the best?</p>
<p>Is anyone studying from Barron’s? Have you heard if studying from Barron’s/Cliffs alone is enough to get a 5?</p>
<p>@CurtisLee: Nice work!</p>
<p>
</p>
<p>Barron’s releases flashcards but I have never personally used them. It is a very reputable test preparation company, though.</p>
<p>
</p>
<p>Many have personal stories of obtaining a 5 after exclusively studying from one or the other. CliffsNotes is a very good resource, but I have found that Barron’s does have better diagrams and multiple choice practice.</p>
<p>Questions 1-4 refer to the following five choices:</p>
<p>[ul] <a href=“A”></a> Translation
<a href=“B”></a> Replication
<a href=“C”></a> Transcription
<a href=“D”></a> Transformation
<a href=“E”>*</a> Termination [/ul]</p>
<ol>
<li><p>The process in which DNA makes messenger RNA</p></li>
<li><p>The process in which DNA is synthesized from a template strand</p></li>
<li><p>The process in which foreign DNA is taken up by a bacterial cell</p></li>
<li><p>The process in which a polypeptide strand is synthesized using mRNA as a template</p></li>
</ol>
<p>I’m pretty sure…</p>
<ol>
<li>C</li>
<li>B</li>
<li>D? </li>
<li>A</li>
</ol>
<p>I don’t know what termination is</p>
<p>Yes, you went four-for-four. :)</p>
<p>
</p>
<p>Basically the final stage of the transcription of RNA.</p>
<p>[ul] [li] DNA replication can best be described as[/li][list] <a href=“A”>*</a> semiconservative
(B) conservative
(C) degenerate
(D) comparative
(E) the same in eukaryotes and prokaryotes [/ul][/list]</p>
<p>Oh wow look at all this bio knowledge haha.</p>
<p>DNA replication is semiconservative =]</p>
