You are studying a plant and inject fluorescein, a fluorescent dye, into a single cell on the surface of the plant.  After a brief period of time, the dye spreads to cells neighboring the injected cell.  What do you conclude?   only one options:   The cells are connected by the cell wall.   The cells are connected by tight junctions.   The cells are connected by gap junctions.   The cells are connected by plasmodesmata.

The words in the parentheses represent the choices for the blanks. The perimeter city walls represent the _______(nucleus, organelles, plasma membrane) of the cell. The area of the city represents the ______ (lipid bilayer, flagella, cytoplasm) of the cell. Just like the city, a living cell has to bring food and nutrients in from outside and move waste products out.

An oceanographer studying the deepest parts of the ocean discovered a new organism growing next to a volcanic vent. This part of the ocean is so deep, no sunlight reaches it at all. The organism they found was too small to see with the eye, and was only discovered after looking through a microscope at samples from this volcanic vent. The oceanographer noticed that the cells of the organism all looked identical and were arranged in long chains. No organelles were visible. Select all the characteristics that accurately describe this organism! O Prokaryotic O Eukaryotic Unicellular O Multicellular O Phototrophic O Heterotrophic

If you could label the questions on the left as (1,2,3,4) etc with the right letters thanks ??
