Document Summary

Eubacteria: all have cell walls except mycoplasms, archaebacteria, have cell walls b. Include extremophiles: halophiles (great salt lake, dead sea, acidophiles, thermophiles (taq polymerase, remember european architecture is pro. Fungi a: have cell walls, heterotrophs (eat food, animals, mulicellular, no cell walls, heterotrophs (eat food, proists (single-cell, diverse, mostly single-celled, but includes some colonies. 2 | p a g e: algae, water molds, slime molds, protozoa, plants, mulicellular, have cell walls, autotrophs (make food, remember fapp. Credited with irst microscope a: viewed cork slices cellula translates to litle rooms , antoni van leeuwenhoek (1632 1723, glassworker improved lens quality to 300x magniicaion b. First to observe: single-celled organisms animalcules , proists from pond water, bacteria from mouth, blood cells. Zoologist observed as schleiden with animal cells: noted similarity between plants and animals, formulated cell theory. Formulation: all organisms consist of 1+ cells. 2: all cells arise from pre-exising cells. The cell is the basic unit of structure for all organisms.

The introductory passage describes the use of fluorescent markers to identify halomucin outside of the cell. How could you distinguish between a prokaryotic cell and a eukaryotic cell by using fluorescent markers to identify ribosomes and to identify DNA?

Choose the best answer.

Hints

Choose the best answer.

The ribosomes would be close to the cell wall and the DNA would be in the center of the cell in prokaryotes, but both would be close to the cell wall in all eukaryotes.

The functional ribosomes would be scattered throughout the cell in prokaryotes but close together in the nucleus in eukaryotic cells.

The ribosomes and DNA would appear farther apart in prokaryotes and eukaryotes because this is important for regulating gene expression in prokaryotes.

The ribosomes and DNA would appear close together in prokaryotes because transcription and translation can occur simultaneously, whereas they would be in different locations in eukaryotes.
