For example, carbon, hydrogen, oxygen, nitrogen, and magnesium are essential elements because they are part of the chlorophyll molecule (Chl a = C55H72O5N4Mg) and the presence of chlorophyll is essential in photosynthesis. Being so, they are directly involved in the autotrophic production of f...
These are the macronutrients you're likely most familiar with, as they're found on the labels of fertilizers as NPK ratios. These are also typically the nutrients sought after inhomemade compostand otherhomemade plant fertilizers. 'Nitrogen promotes leafy growth. It is a building block for chl...
quite effective. According to 1973, the Japanese Society for Nutritional Improvement published, continuous use of chlorella for about two months, because chlorella is rich in chlorophyll and chelated iron elements, the blood of iron and hematocrit will increase and become normal. The short...

Are they unique to Earth or could there be other environments, elsewhere in our Solar System or on exoplanets, for example? Organic molecules are present throughout the universe.它们是地球独有的吗，还是可能也存在于其他环境之中，比如在太阳系的其他地方或者系外行星上？有机分子遍布整个宇宙。But the...

(tracheary) elements are only vessels or tracheids, and analogically to phloem, xylem fibers, and parenchyma cells with different functions are present. Tracheary elements in xylem are dead at maturity, while sieve elements in phloem are still-living cells lacking certain organelles, such as ...
Fireflies are one example of bioluminescence that you may already be familiar with. However, most bioluminescence is found in organisms that live in the ocean. Glow worms, giant glowing squids, jellyfish and shining sea snails all contain elements of bioluminescence. ...
In addition to NPK, secondary nutrients such as Calcium (Ca), Magnesium (Mg), and Sulfur (S) are vital for plant structure and function, while trace elements like Iron (Fe), Manganese (Mn), and Zinc (Zn) are required in smaller amounts but are critical for various enzyme functions....
What is the function of vitamin C? What are some food sources? What elements do plants synthesize? Give an example of a water-soluble vitamin and a food source of it. What metal is present in the chlorophyll? What are the primary functions, deficiency signs/symptoms, and main food sources...
