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.
Your resting heart rate should be between 60-100 beats per minute. If you are an athlete or train a lot, your resting heart rate could be lower. That is an average. Resting heart rate above 150 is tachycardia (fast).During exercise, you should shoot for between 40-60% of your heart rate max which is generally estimated by subtracting your age from 220. Example a 20 year old (220-20=200) would have a max heart rate of 200.esting heart rate above 150 is tachycardia (fast). During exercise, you should shoot for between 40-60% of your heart rate max which is generally estimated by subtracting your age from 220.
