It has rained for several days. A tomato plant root system senses the large amount of water and produces the hormone abscisic acid, which triggers the guard cells to swell. When the guard cells swell, the stomatal pore opens, and water loss increases. Using stored glucose and newly absorbed water, reproduction of flowers begins and tomatoes begin to grow. 1) Written Answer to Scenario 8:
.
2) What two systems are interacting in this scenario? and

no

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.
