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.
Zinc deficiency
characterized by a slight intrauterine growth retardation, relatively normal growth rates for the first several years of life, a progressive deceleration of growth later in childhood, and the lack of a pubertal growth spurt.
autonomic movment due to interal causes and paratonic movment due external caues
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.
Primary growth is responsible for elongating the plant. In woody plants, primary growth is then followed by secondary growth which allows the plant stem to increase in thickness or girth.
The following are the factors responsible for the proper growth of plants and seeds.sunlight/light(artificial)watersoilair (mainly co2)Growth hormones
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.

Assuming you mean at birth ... CO causes oxygen depletion, and thus growth retardation.
cerebral palsy
Retardation.
Fetal alcohol syndrome. This includes decreased development of the fetus, intra-uterine growth retardation, mental retardation.
yes
There are many causes of retardation. These includes Down syndrome, velocariofacial syndrome, fetal alcohol syndrome, problems during pregnancy and other genetic disorders.
In children, chronic malnutrition is marked by growth retardation.
some symptoms you can have with pku is babies can have brain damage which causes mental retardation another symptom is the baby can stunt its growth and your baby is most likely to stay small for life
