Mainly lack of light. Without light, plants are unable to photosynthesis and thus cause growth retardation which may sometimes lead to death of the plant.
Green light causes the least amount of plant growth because plants reflect green light rather than absorb it for photosynthesis. This is why plants appear green to us, as they do not utilize green light effectively for growth.
Auxins are chemicals exist in plants to stimulate growth. When sunlight hits one side of the stem of a plant, the auxins move away and down from the sunlight. This causes the 'dark' side of the stem to grow faster than the 'lighted' side, which causes the stem to lean towards the source of the light.
Stem cell research has the potential to help with mental retardation by better understanding the underlying causes of intellectual disabilities and developing new treatments. However, more research is needed to fully understand how stem cells could be used to improve outcomes for individuals with mental retardation.
No, woody plants do not lack secondary growth. Secondary growth is the process by which plants increase their girth through the production of secondary tissues such as wood and bark, which woody plants exhibit. This growth allows woody plants to increase in size and longevity.
Phosphorus is indispensable for the growth of plants.
Copper deficiency in children is associated with growth retardation. Zinc deficiency, Vitamin A deficiency and other nutritional deficiencies can also cause growth retardation.
Overstudy does not cause mental retardation.

Retardation.
cerebral palsy
yes
There are many causes of retardation. These includes Down syndrome, velocariofacial syndrome, fetal alcohol syndrome, problems during pregnancy and other genetic disorders.
Fetal alcohol syndrome. This includes decreased development of the fetus, intra-uterine growth retardation, mental retardation.
In children, chronic malnutrition is marked by growth retardation.
Green light causes the least amount of plant growth because plants reflect green light rather than absorb it for photosynthesis. This is why plants appear green to us, as they do not utilize green light effectively for growth.
In 4% of bacterial meningitis cases in children, there is seen to be some mental retardation.
