Prokaryotic and Eukaroytic Cells

Bacterial cells are prokaryotic. Choose two structures of bacterial cells and explain how these structures allow bacteria to function as unicellular organisms. There are many examples of eukaryotic cells. Algae, Fungi, Plants, and Animals are all composed of eukaryotic cells. Some algae and fungi are unicellular organisms, b

Cell Types and Natural Selection

1. What are prokaryotes and eukaryotes? List three (3) ways prokaryotes differ from eukaryotes. 2. Natural selection is essentially a two-step process, what are the two steps? Ideas and research are included.

ATP yield per glucose in eukaryotic vs prokaryotic cells

Please help with the following problem. The maximum yield of ATP per molecule of glucose in eukaryotic cells varies from 36 to 38 ATP. In prokaryotic cells, the maximum yield is 38 ATP. Explain why the maximum yield in eukaryotes varies, and why this is not an issue in prokaryotic cells

Prokaryotic and Eukaryotic Cells

Prokaryotic and eukaryotic cells share many similar features, developed and fine-tuned through years of evolution. Interestingly, the majority of prokaryotic cells exist as simple unicellular organisms, and only on rare occasions can grow together in colonies or demonstrate any type of intercellular communication. Eukaryotic cel
