cell questions?

Question

I'm really confused about these questions

What are the smimilarities and differences between a plant and animal cell structures?

Where in a cell would you find genetic information?

Cilia also function to remove dirt and debris. Where in the human body might you find cells with cilia? Explain your answer

Please help i'm connnnfused

Answer 1

Plant cells have large vacuoles, cell walls, and lack centrioles. Animal cells lack cell walls, vaculoes, and have a pair of centrioles.

You would look in the nucleus, where the DNA is concentrated in chromatin.

You would find cells with cilia in the windpipe/trachea to remove dirt, as well as in your nose/sinus.

Answer 2

What's confusing about them? Any decent introductory bio text will have diagrams that answer the first question. Try Curtis and Barnes, "Invitation to Biology" or Campbell, "Biology".

If it's a eukaryotic cell, in the nucleus. Also in the mitochondria and (for plants) chloroplasts. In prokaryotic cells, the genetic information is carried in a single, circular chromosome within the cytoplasm.

Well, think about it. Where do you want to remove dirt and debris? Maybe the nasal passages? Or the esophagus?
