Plants: haploid generation of a plant produces gametes (sperm and eggs) and is called the gametophyte; the diploid generation produces spores and is called the sporophyte/ diploid zygote.
1 You gain the most benefits and lessen the risks when you exercise in your target heart rate zone. 2  Usually this is when your exercise heart rate (pulse) is 60 to 80 percent of your maximum heart rate. 3  In some cases, your health care provider may decrease your target heart rate zone to begin with 50 percent.
If that's the case for you, then taking your heart rate during exercise and using a target heart rate training zone might be just the ticket. Target heart rate zones range anywhere from 50% to 100% of your maximum heart rate (your maximum heart rate is based on your age).Aerobic exercise is anything less than 85%, and anaerobic exercise is anything above that.f you plug in other values, you can get other ranges. 1  220-age = Max HR. 2  Subtract resting heart rate from Max HR = Heart Rate Reserve (HRR). 3  Multiply HRR times percent you want to train at. 4  Add back resting heart rate. 5  Assuming a resting heart rate of 70 bpm, 27 years old, and 70% training range: 6  220 - 27 = 193.
