Nesse grupo de células, o DNA é circular. • Nas células procarióticas, também não há citoesqueleto e organelas membranosas, tais como mitocôndrias, retículos endoplasmáticos e complexo golgiense. A presença de ribossomos é descrita, entretanto, eles são menores e menos complexos que aqueles encontrados em uma célula eucariótica. • Em razão da ausência de mitocôndrias, as moléculas da cadeia respiratória estão presentes na face interna da membrana plasmática. Além disso, nessas células, não ocorre o processo de endocitose e exocitose. ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ Slide 11 ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ Slide 12 Células eucariótas • Células As células eucarióticas (do grego eu: verdadeiro e karyon: núcleo) são muito mais complexas que as células procarióticas. Nesse grupo de células, é possível observar um envoltório nuclear delimitando um núcleo, uma das características mais marcantes desse tipo celular. • Além do núcleo verdadeiro, as células eucarióticas apresentam organelas membranosas e citoesqueleto. Processos como endocitose e exocitose estão presentes, além da divisão celular por mitose ou meiose, os quais não são observados em procariontes. ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ Slide 13 ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ Slide 14 Quais as principais diferenças entre Gram-positivas e Gram-negativas? As bactérias Gram-positivas adquirem coloração azul quando essa coloração é aplicada a elas. As outras bactérias adquirem coloração vermelha. Elas são chamadas de Gram-negativas. As bactérias Gram-positivas e Gram- negativas têm a coloração diferente porque suas paredes celulares são diferentes. ___________________________________ ___________________________________
