As organelas são estruturas intracelulares envoltas por uma membrana, como exemplo temos o ribossomo e a mitocôndria.Questão 8Escolha uma opção:VerdadeiroFalso

Analyzing the Statement

1. Understanding Organelles: Organelles are specialized structures within cells that perform distinct functions. They can be membrane-bound or non-membrane-bound. Examples include the nucleus, mitochondria, ribosomes, and lysosomes.

2. Definition of Ribosomes and Mitochondria:

   • Ribosomes: They are not membrane-bound organelles. They can be found floating freely in the cytoplasm or attached to the endoplasmic reticulum.
   • Mitochondria: These are membrane-bound organelles responsible for energy production through cellular respiration.

Evaluation of the Statement

Given that ribosomes are not surrounded by a membrane, the statement that claims organelles are membrane-bound structures does not hold true for ribosomes.

Conclusion

The correct answer to the question is Falso. The statement is false because not all organelles are enclosed by membranes.
