Question

Lab Sections AM Names PM Microscopes and Cells Questions for Review 1. What are the primary differences between eukaryotic and prokaryotic cells? 2. What characteristics do all eukaryotic cells have in common? 3. What cellular features differentiate plants from animals? 4. How are the structures that are unique to plants important to their success? Applyin Your Knowledge 1. In your own words, describe the evolutionary tread for increasing organismal complexity, using examples from this lab to illustrate your answer. 2. We often imply that multicellular organisms are more advanced (and therefore more successful than unicellular or colonial organisms. Explain why this is not true, using examples from this lab or elsewhere General Biology (BIO K121) Page 78

Answer 1

1.prokarotes have pro karyon which means primitive nucleus which lack nucleolus and nuclear membrane.

Where as eukaryotes have all four parts of nucleus.

PROKARYOTES lacks well developed membrane bound organelles.

Whereas eukaryotes have well developed membrane bound organelles.

PROKARYOTES have 70 s ribosome whereas eukaryotes have 80 s ribosomes.

2) all eukaryotes will have 80 s ribosome.

They have nuclear envelope and nucleolus in their nucleus

They have membrane bound organelles.

3)plants cells can photosynthesis which makes food that means plant are autotrophs whereas animal can't because they don't have chlorophyll

4)plant cells have cell wall which maintain their shape and plant cells also have chloroplast which can photosynthesis and can contain various food.
