All cell communication systems are used for sexual reproduction. Question 5 Explanation:. Even though the last common ancestor of yeast and mammals lived over a billion years ago, the molecular details of signal transduction in yeast and mammals is very similar. Question 6. Which of the following is an example of long-distance cell signaling? Question 6 Explanation:. Cell-cell recognition involves direct contact between cells.

Synaptic signaling requires the nerve cell to be very close to the target cell.

Plasmodesmata in plant cells is a junction that allows molecules to pass between adjacent cells with out having to cross the plasma membrane. Hormones are used by plants and animals for long-distance signaling. Question 7. Questions 7—9: Use the diagram below to identify the activity or object in the pathway. Which letter represents the plasma membrane of the cell? Question 7 Explanation:. The plasma membrane is the selectively permeable layer of molecules that encloses the cell. Question 8. Which letter represents a signaling molecule coming from outside the cell?

Question 8 Explanation:. The correct answer is A. The receptor protein detects the signaling molecule when the signaling molecule fits into the receptor. Question 9. Which letter represents the conversion of the signal to a form that brings about a cellular response? Question 9 Explanation:. The correct answer is D. Signal transduction pathways are a sequence of changes in a series of molecules, that allows information to trigger a cellular response.

  • Two single celled prokaryotic cells are undergoing asexual reproduction. Question 10 Explanation:. What biological process is taking place in the diagram? Question 11 Explanation:. The binding of the factors to the receptors leads to the fusion of the two cells. This zygote can then undergo mitosis leading to the formation of a diploid bud. During which process do cells enter into programmed cell death, during which time DNA is chopped up, organelles are fragmented, the cell shrinks and parts of the cell are packaged into vesicle and removed by scavenger cells?

    Question 12 Explanation:. Aptosis is controlled suicide of the cell.

    Catastrophism is the idea that events in the past occurred suddenly and were caused by different mechanisms than those operating today. Cytokinesis is the division of the cytoplasm to form daughter cells after mitosis. Endocytosis is process by which materials enter the cell via the formation of vesicles.
