  1. Células Profª. Lilian Larroca

  2. | Célula – menor unidade de um ser vivo Profa. Lilian Larroca

  3. | Célula – menor unidade de um ser vivo Profa. Lilian Larroca

  4. | Células de uma folha Profa. Lilian Larroca

  5. | Alguns seres são formados por uma única célula – são seres unicelulares Acetabularia – alga unicelular marinha, com cerca de 4 cm de altura. Profa. Lilian Larroca

  6. | Porém, a maioria dos seres vivos possui mais de uma célula – são os pluricelulares. Profa. Lilian Larroca

  7. | Nosso corpo também é formado por células Profa. Lilian Larroca

  8. | Nosso corpo tem cerca de 200 tipos de células diferentes – sua forma varia de acordo com sua função Célula fusiforme – músculos lisos Célula estrelada - neurônio Células arredondadas – glóbulos vermelhos Células cúbicas e cilíndricas - pele Profa. Lilian Larroca

  9. | Nosso corpo tem cerca de 200 tipos de células diferentes – sua forma varia de acordo com sua função Profa. Lilian Larroca

  10. | Por dentro, a célula tem muitas partes (cada parte tem uma função): Profa. Lilian Larroca

  11. Porém, por enquanto, enfocaremos apenas as principais partes: Profa. Lilian Larroca

  12. | Núcleo • O núcleo é o centro de controle da célula. Ele é responsável pela reprodução E nutrição celular. • No interior do núcleo ficam os cromossomos, que são formados por DNA. No DNA ficam os genes,q eu carregam as características do indivíduo. • A maioria das células do corpo humano possui núcleo, mas algumas são anucleadas (hemácia adulta) e outras possuem mais de um núcleo (células do fígado). Profa. Lilian Larroca

  13. | Citoplasma • O citoplasma fica entre o Núcleo e a membrana plasmática. É um tipo de líquido viscoso (geleia), no qual ficam várias organelas – partes da célula que têm funções importantes (produção de energia, produção de proteínas, digestão da célula, eliminação de substâncias da célula, etc... Profa. Lilian Larroca

  14. | Membrana plasmática • É a “parede” da célula, que a separa de outras células, mas permite que certassubstâncias entrem e saiam da célula. Ela é seletiva – “escolhe” as substâncias que podem entrar na célula e as que não podem. Ela permite a entrada de nutrientes, oxigênio e outras substâncias, mas impede ou dificulta a entrada de substâncias tóxicas. Profa. Lilian Larroca

  15. | As células se reúnem e formam tecidos Profa. Lilian Larroca

  16. | Os tecidos formam órgãos Profa. Lilian Larroca

  17. | Os órgãos, reunidos, formam sistemas Profa. Lilian Larroca

  18. | Os sistemas, reunidos, formam o corpo. Profa. Lilian Larroca
