Answer:
Chlorophyll is a green pigment found in chloroplast in plants. It absorbs sunlight during the process of photosynthesis. It is a chelate molecule. In a chelate molecule a central metal ion forms bonds with a large organic molecule made of carbon, hydrogen and other elements like nitrogen or oxygen.
In chlorophyll, magnesium is the central metal ion and it is bonded to a large organic molecule called as porphyrin. Porphyrin constitutes four nitrogen atoms to which the central magnesium is bonded in square planar arrangement. Since chlorophyll is responsible for the green color of the leaves, more the green color more the chlorophyll content and more is the nitrogen content. Hence, chlorophyll meter measures this green light and finds out if the plant needs more or less nitrogen.
Some plants have a complex life cycle that includes the sporophyte and,gametophyte stages.
Answer:
The synthesis of new proteins
Water has a high heat capacity, or the ability to "hold on to" heat well; this property aids in the regulation of body temperature in both organisms and cells. Sweating is another way that water can be used to cool down an overheated organism.
- Warm-blooded animals employ water's high heat capacity to more efficiently distribute heat throughout their bodies.
- Water works like a car's cooling system, moving heat from warm to cold areas and allowing the body to maintain a more constant temperature.
- The body requires water to maintain temperature because it is a good heat conductor and absorber.
- Water can absorb a lot of heat before its temperature increases because of its large heat capacity.
- This characteristic enables the water to function as a buffer against abrupt temperature changes in every cell of the human body.
