Série: 2EM&nbsp;&nbsp;&nbsp; Turma:__________ &nbsp;&nbsp;&nbsp;Data: 



1. Conteúdo:
Plantas Avasculares – Briófitas (Musgos)



2. Objetivo(s):

* Observar e
identificar as estruturas que constituem as Briófitas

* Identificar os
rizoides, cauloides, filoides, cápsula, esporos, a partir da análise
microscópica do musgo.

* Diferenciar a
geração gametofítica da esporofítica, presentes nos musgos, a partir de sua
análise&nbsp;

&nbsp;&nbsp; macroscópica.

* Reconhecer a
localização das estruturas reprodutoras.



&nbsp;3. Fundamentação Teórica

4. Materiais
Utilizados:

5. Desenvolvimento
(Procedimento, Técnica)

a)
Examinar o material na placa de petri sobre a bancada;

b)
Com o auxílio de uma pinça, retirar uma pequena quantidade do material (musgo)
contendo gametófito e esporófito;

c)
Colocar sobre a placa de petri e observar no Microscópio estereoscópico.
Desenhar o que observou.

d)
Retirar apenas um exemplar do musgo, colocar em uma lâmina, adicionar uma gota
de água, cobrir com lamínula e observar no MO. Desenhar o que observou.



6. Identificar e
desenhar as estruturas observadas no musgo.
