Why do some seeds need scarification? Some seed coats are impervious to water. It is nature’s way of protecting the seed during dormancy. Fall planted seeds that go through a freeze/thaw cycle or pass through the digestive system of an animal naturally scarify. Did you ever notice how seed...
Why do plant roots absorb water mainly by osmosis? Why does a high concentration of salt in the soil tend to reduce germination? Why do wrinkled peas absorb more amounts of water? Please explain microscopically and biochemically. Plants take in large qua...
Seeds are a protective coating that forms around the fertilized embryo of a flowering plant. There are a wide variety of types of seeds, and plants can either be monocots or dicots depending on the number of embryonic seed leaves they have. Not all plants have seeds, but they are an ...
Depending on the water quality used in the process, hydroponic tomato plants may live for as little as 6 months or as long as 2 years. Don’t miss out on my full guide “Hydroponic Tomatoes 101” – learn everything you need to get started – it’s easier than you think! How To Ex...
If the seeds are not fresh, put them in a jar, and fill it with lukewarm water. The seeds need soaking for a few days to speed up germination. Change the water every two days. Choose a sunny site in the garden that gets between 6 and 8 hours ofdirect sunlightduring the spring and...
If seeds needing sunlight are buried inside a tight ball of clay, they may never germinate. However, if the ball breaks apart when it gets wet, sunlight may reach the seeds. If you make your own seed bombs, be sure to read the germination requirements for each species of seeds you use...
It is concluded that temperature is one of the critical factors for germination of W. whytei seed. The ability of W. whytei seeds to germinate both in light and darkness implies that the species would unlikely form a persistent soil seed bank, an attribute which is common in species that ...
Seeds Are Old– Seeds that are old tend to have lower germination rates and sometimes grow at a slower pace. More Sensitive to Overwatering– One of the most common reasons seedlings grow slow is they areoverwatered. This is often accompanied by general droopiness. Some plants simply drink ...
Plant seeds soaked in water swell and become several times as large as before soaking. Why does this happen? Why do leaves turn red, orange and yellow in the fall? Briefly state why the leaves of plants have a green color. Why do some plants need less water than others?
(a) Do mature seeds need sunlight to germinate? (b) Why or why not? What effect do you hypothesize freeze-thawing will have on lentils and why? Why predators don't always drive their prey to extinction? Enumerate a reason why it is important for a plant to have stomata. ...
