Inside each new seed there is a tiny plant embryo which looks like a tiny stem and leaves tucked into a kind of fetal position. The seed also contains enough nutrition for the new plant to use until it sprouts and begins to manufacture its own food by photosynthesis.
Infections are the most common causes of coughing up blood. They account for 60 to 70 percent cases of all haemoptysis.

âEven a little cough can be debilitating,â says Mark Yoder, MD, assistant professor of pulmonary and critical care medicine at Rush University Medical Center in Chicago. Cold and flu season brings on hacking coughs that can leave your chest muscles aching. But colds and flu arenât the only problems that cause coughing. Allergies, asthma, acid reflux, dry air, and smoking are common causes of coughs. Even medications such as certain drugs for high blood pressure and allergies can cause chronic cough.
