Assim nesse tipo de divisão uma célula germinativa (2n) é dividida em quatro células-filhas (n). Para ocorrer a redução da carga genética a célula passa por dois ciclos de divisão. &lt;/em&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;ul&gt;&lt;li&gt;&lt;em&gt;&lt;strong&gt;Meiose I&lt;/strong&gt; - caracteriza-se pelas fases de Prófase I (Leptóteno, Zigóteno, Paquíteno, Diplóteno e Diacinese), Metáfase I, Anáfase I, Telófase I&lt;/em&gt;&lt;/li&gt;&lt;li&gt;&lt;em&gt;&lt;strong&gt;Intercinese&lt;/strong&gt; - estágio em que a célula se prepara para a meiose II.&lt;/em&gt;&lt;/li&gt;&lt;li&gt;&lt;em&gt;&lt;strong&gt;Meiose II&lt;/strong&gt; - caracteriza-se pelas fases de Prófase II, Metáfase II, Anáfase II, Telófase II.&lt;/em&gt;&lt;/li&gt;&lt;/ul&gt;&lt;p&gt;&lt;em&gt;&lt;/em&gt;&lt;/p&gt;&lt; &lt;a href="http://4.bp.blogspot.com/_-GeecIWEsMk/SrkKBkjKHEI/AAAAAAAAAPo/7k_GBbAoocg/s1600-h/Slide1.JPG"&gt;&lt;img id="BLOGGER_PHOTO_ID_5384345851605425218" style="WIDTH: 400px; CURSOR: hand; HEIGHT: 300px" alt="" src="http://4.bp.blogspot.com/_-GeecIWEsMk/SrkKBkjKHEI/AAAAAAAAAPo/7k_GBbAoocg/s400/Slide1.JPG" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;a href="http://2.bp.blogspot.com/_-GeecIWEsMk/SrkKBcOlveI/AAAAAAAAAPg/XyKwLeG82lI/s1600-h/Slide2.JPG"&gt;&lt;img id="BLOGGER_PHOTO_ID_5384345849371672034" style="WIDTH: 400px; CURSOR: hand; HEIGHT: 300px" alt="" src="http://2.bp.blogspot.com/_-GeecIWEsMk/SrkKBcOlveI/AAAAAAAAAPg/XyKwLeG82lI/s400/Slide2.JPG" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;a href="http://3.bp.blogspot.com/_-GeecIWEsMk/SrkKAzdoTdI/AAAAAAAAAPY/-j_JrT5-as8/s1600-h/Slide3.JPG"&gt;&lt;img id="BLOGGER_PHOTO_ID_5384345838428900818" style="WIDTH: 400px; CURSOR: hand; HEIGHT: 300px" alt="" src="http://3.bp.blogspot.com/_-GeecIWEsMk/SrkKAzdoTdI/AAAAAAAAAPY/-j_JrT5-as8/s400/Slide3.JPG" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;a href="http://2.bp.blogspot.com/_-GeecIWEsMk/SrkKAr3YfQI/AAAAAAAAAPQ/k9dkybJP_vM/s1600-h/Slide4.JPG"&gt;&lt;img id="BLOGGER_PHOTO_ID_5384345836389432578" style="WIDTH: 400px; CURSOR: hand; HEIGHT: 300px" alt="" src="http://2.bp.blogspot.com/_-GeecIWEsMk/SrkKAr3YfQI/AAAAAAAAAPQ/k9dkybJP_vM/s400/Slide4.JPG" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;a href="http://1.bp.blogspot.com/_-GeecIWEsMk/SrkKAM6JpmI/AAAAAAAAAPI/de0-QtOp7DY/s1600-h/Slide5.JPG"&gt;&lt;img id="BLOGGER_PHOTO_ID_5384345828079543906" style="WIDTH: 400px; CURSOR: hand; HEIGHT: 300px" alt="" src="http://1.bp.blogspot.com/_-GeecIWEsMk/SrkKAM6JpmI/AAAAAAAAAPI/de0-QtOp7DY/s400/Slide5.JPG" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;&lt;em&gt;O significado biológico da meiose&lt;/em&gt;&lt;/strong&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;em&gt;Na prófase I da meiose ocorre o &lt;strong&gt;crossing over&lt;/strong&gt; entre os cromossomos homólogos esse evento é muito importante pois garante a variabilidade genética de indivíduos de uma mesma espécie.&lt;/em&gt;&lt;br /&gt;&lt;em&gt;Qualquer erro na anáfase I ou na anáfase II pode gerar gametas defeituosos que se forem fecundados darão origem a indivíduos com anomalias genéticas.

É também o mescanismo mais comum de reprodução dos organismos unicelulares eucariontes. É também o processo pelo qual os pluricelulares são formados, seja a partir de um pedaço do corpo (reprodução assexuada) ou através da fecundação. Esse processo explica também o crescimento, a renovação celular, a regeneração tecidual e a formação de tumores cancerígenos.&lt;/span&gt;&lt;/em&gt;&lt;/div&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;div align="justify"&gt;&lt;em&gt;&lt;/em&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;em&gt;&lt;strong&gt;&lt;span style="font-size:180%;"&gt;Ciclo celular&lt;/span&gt;&lt;/strong&gt;&lt;/em&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;em&gt;O período entre o início de uma mitose e outra é chamdo de ciclo celular; a nele a célula cresce, prepara-se para divisão e divide-se.

Nas células animais o citoplasma é estrangulado por ação das fibras de miosina, actina e tubulina orientadas pelos centríolos. Já as células vegetais, como não possuem centríolos a divisão do citoplasma ocorre com a formação do fragmoplasto que por ação do complexo golgiense irá produzir e secretar a celulose para compor a parede celular.&lt;/em&gt;&lt;br /&gt;&lt;em&gt;Assim temos:&lt;/em&gt;&lt;br /&gt;&lt;/p&gt;&lt;ul&gt;&lt;li&gt;&lt;em&gt;&lt;strong&gt;Célula Vegetal:&lt;/strong&gt; citocinese é&lt;strong&gt;

perderam os dentes que foram substituídos pelo bico, papo e moela.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;O bico está diretamente relacionado e adaptado ao tipo de alimento do animal, portanto varia de formato e tamanho de acordo com a espécie observada.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;O papo&lt;a href="http://4.bp.blogspot.com/_-GeecIWEsMk/Sp1fqO4U2lI/AAAAAAAAAEg/vdRK9I25S7U/s1600-h/aves.jpg"&gt;&lt;img style="MARGIN: 0px 0px 10px 10px;

tem uma função parecida com a saliva, pois armazena temporariamente o alimento para torná-lo mais mole.&lt;br /&gt;&lt;br /&gt;A moela pode ser comparada à boca e aos dentes dos mamíferos pois permite através da contração muscular quebrar o alimento em pedaços menores já que ainda não havia sido mastigado.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;Outra diferença desse sistema é a presença de cloaca como porção final. A cloaca é utilizada tanto como via de excreção (ácido úrico), quanto digestão e postura de ovos (reprodução).&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;Répteis e Anfíbios&lt;/strong&gt;&lt;br /&gt;&lt;strong&gt;&lt;/strong&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;a href="http://3.bp.blogspot.com/_-GeecIWEsMk/Sp1hyNrXdgI/AAAAAAAAAEw/d8K7knLOkTA/s1600-h/anfibios.jpg"&gt;&lt;img style="MARGIN: 0px 10px 10px 0px;
