What is the only Cell Junction in Plant cells? Why do Plant cells only have one type of Cell Junction?
Explain Cell-Cell signaling involving Signal Transduction and G-Proteins.

Expert Solution

1.Cell junction is the cell to cell direct contact made for intercellular communication. In plant Plasmodesmata is the only cell junction .

2.Plants have only one kind of cell junction because plant cell posses cell wall due to which plasma membrane of one cell cannot touch with neighbouring cells. Therefore microscopic channels are formed in cell wall which conect cytoplasm of one cell to neighbouring cell and that channel is nothing but the plasmodesmata.

3. Cell-Cell signaling involving Signal Transduction and G-Proteins.- The cell signalling mechanism which involves signal transduction through G-proteins coupled receptors and G- proteins is called GPCR signalling.

Plant cells are different from animal cells in several ways. All plant cells have a cell wall during their entire existence. The cell wall has many different functions in different cell types. Compare and contrast between the two types of plant cell walls as to their chemical make up, shape, when they are formed, and morphological properties. Include all chemical components in the cell wall we discussed during lecture. Draw two figures showing how each of these cell walls are...

Why do cells have telomeres? Why do telomeres get shorter every time a cell divides? What counteracts this shortening? What role do telomeres play in aging? If telomerase makes cancer cells immortal, could it prevent normal cells from aging? Do you think we could extend the average lifespan by preserving or restoring the length of telomeres with telomerase? If so, does that raise a risk the telomerase also will cause cancer?

Hormones: A. relay a message from one cell only to its neighboring cells. B. have the same effects on all cell types. C. are made only of proteins. D. bind to receptors and cause transmission of a signal to the interior of the cell. Which of the following is NOT true of metabolic fates in liver cells? A.

Cells and Viruses Observe and draw the following cells. Plant cell (slide) – Note cell wall, chloroplast What does this tell you about the functions of this cell? Pancreatic cell (slide) – Note large amounts of endoplasmic reticulum and ribosomes. What do these structures reveal about its function? Virus (Electron micrograph) – Note the lack of organelles. Why do viruses need to infect a host cell to reproduce? Table 1 Drawing of Cell Include total magnification Organelles observed Summarize your...

Explain why there is the optimized bandgap for single-junction photovoltaic cell, in which the cell efficiency initially increases as a function of bandgap, reaches a peak at certain value of bandgap, and then decreases as bandgap further increases. Explain difference between superstrate and substrate configuration in thin-film photovoltaic cells.

E) Totipotent, unipotent, multipotent, and pluripotent are all types of stem cells.
