Use the figure below depicting sea urchin fertilization to answer the next question. Sea urchin fertilization Sperm plasma membrane Sperm nucleus. Fertilization envelope Basal body (centriole) Sperm head Acrosome- Jelly coat Sperm-binding. receptors Figure PDF: fertpic.pdf Actin filament. 1848007 Acrosomal process ?? ?? ?? - Cortical Fused plasma granule membranes Hydrolytic enzymes Vitelline layer Egg plasma membrane Perivitelline space EGG CYTOPLASM Question 8 3.8 pts Imagine that there was an abnormality in step [4] of this figure which prevented the cortical granules from fusing with the plasma membrane. Which of the following BEST describes how this would affect fertilization? O Nothing will change, as the cortical granules do not fuse with the plasma membrane. These structures prevent polyspermy by making the egg's internal charge more positive. O The fertilization envelope would not form and the slow block to polyspermy would not take place. This could increase the odds of polyspermy. O The egg cell would likely continue through to step [5], but egg activation and increased cellular respiration would not occur. O The egg cell would revert back to step [3] until the cortical vesicles fuse, triggering the fast block to polyspermy.
