Elan Coil [88]

Answer:Transpiration

Explanation: water cycle is the continuous movement of water on the Earth to ensure the availability of water.water is a universal solvent that is essential for the survival of living things.water cycle ensure that clean water is available.plants require water which is gotten from the soil.water is lost from the leaves of trees through transpiration.transpiration may also occur through the lenticels and stomata of stems.

the movement of water through the plant is called transpiration pull.this is responsible for the pull of water into the leaves.it increases the absorption of minerals from the soil and also cools the plant.

This water vapour that transpire from the plant,is condense as clouds, which then falls to the Earth as rain and the water cycle continue

If you were making a product of artificial "Grow-Lites" for plants, what color light should
UNO [17]

Answer:

<u>-blue and red light</u>

Explanation:

Plants produce sugars or carbohydrates during the process of photosynthesis. They absorb light energy from the electromagnetic spectrum with pigments within the thylakoid membrane, like chlorophyll a, chlorophyll b.

Chlorophylls are made of ringed molecules chlorine, a hydrogenated form of porphyrin with a magnesium ion bonded to four atoms of nitrogen. Chlorophyll a shows the most absorption of red light  (642 nm) and blue light (372 nm); while chlorophyll b shows the most absorption at 626 nm and 392 nm.  

Different types of chlorophyll sidechains change the molecules' absorption ranges; A's methyl group is bound at carbon 7,  B's aldehyde (CHO) ring is bound at carbon 7.  Both absorb light from orange-red and violet-blue wavelengths. As such, the best light wavelengths for photosynthesis are within the blue and red wavelengths (425–450 nm) and (600–700 nm).
