Nits are actually the immature, larvae stage of lice, but the two words are often used interchangeably. A lice comb will remove both lice and nits. You can get one at any drug store. add a comment.
Photoperiodism is a response that certain plants have to decreases or increases in the amount they receive in a day (which is normally produced by seasonal movement of the su â¦ n-longer and shorter days).  Some plants require short days to initiate flower formation, while others long day length initiates flowering.
Photo in phototropism means light. Light is a stimulus that plants have response to. A stimulus could be weather, touch, gravity or light. The orientation of a plant or other organism in response to light, either toward the source of light or or away from it. It is usually observed in plants, but can also take place in other organisms such as fungi. The cells on the plant that are farthest from the light have a chemical called auxin that reacts when phototropism occurs which causes the plant cells to get longer on the furthest side of the light.
