These are usually simple squamous epithelial cells. The epithelium lining the body cavities is called the mesothelium and is where the cancer mesothelioma arises from. The epi â¦ thelium lining arteries and veins is called endothelium. 7 people found this useful.
You can place the container in a plastic bag or cover it with a sheet of plastic. Allow for some air to circulate but don't let the mix dry out. Dry seeds will not germinate. #6 Patiently Wait for Germination Place the germination container in a warm location out of direct sunlight. Light is not needed during the germination process, but will not be harmful as long as high temperatures are avoided. Tomato seeds usually germinate within 5 to 10 days when kept in the optimum temperature range of 70 to 80F (21 to 27C). Germination is delayed by lower temperatures and accelerated by higher temperatures. Temperatures below 50F (10C) or above 95F (35C) are detrimental to germination.
I F you want to get your vegetable garden off to a fast start, you need to plant your seeds in soil that's warm enough to ensure good germination. For each type of seed â beans, carrots, lettuce â there is a range of temperatures at which that particular type of seed will germinate (see the chart at right). Beans, for example, will only germinate if the soil temperature is above 60 degrees F and no warmer than 95 degrees F. There is also an optimum temperature at which seeds germinate most readily. In the case of beans, that optimum germination temperature is 80 degrees F. In a perfect world, you would wait for the soil in your garden to be 80 degrees F before planting your beans.
