Seeds fundamentally are means of reproduction, and most seeds are the product of sexual reproduction which produces a remixing of genetic material and phenotype variability on which natural selection acts. Plant seeds hold endophytic microorganisms that can perform various functions, the most important of which is protection against disease. [26]
An important constraint on wind dispersal is the need for abundant seed production to maximize the likelihood of a seed landing in a site suitable for germination. Some wind-dispersed plants, such as the dandelion, can adjust their morphology in order to increase or decrease the rate of diaspore detachment. [ 25 ]
Seed germination depends on both internal and external conditions. The most important external factors include right temperature, water, oxygen or air and sometimes light or darkness. [2] Various plants require different variables for successful seed germination.
Why gardening improves your mood, cardiovascular health, diet and more. Gardening has great mental and physical health benefits. Here's why you should pull weeds and plant seeds.
An important function of seed dormancy is delayed germination, which allows dispersal and prevents simultaneous germination of all seeds. The staggering of germination safeguards some seeds and seedlings from suffering damage or death from short periods of bad weather or from transient herbivores ; it also allows some seeds to germinate when ...
Sesame seeds are also an important source of vitamins and minerals, such as vitamin E, calcium and iron. These essential nutrients support bone health, heart health and immunity, Dieb notes.
Seeds and spores can be used for reproduction (e.g. sowing). Seeds are typically produced from sexual reproduction within a species because genetic recombination has occurred. A plant grown from seeds may have different characteristics from its parents. Some species produce seeds that require special conditions to germinate, such as cold treatment.
Experts explain what seed oils are, their benefits, and why they get so much hate. ... Willett determined that the “most important single change was the likely increase in polyunsaturated fat ...
