Solution
The correct option is A Amyloplasts
Statoliths are dense amyloplasts organelles that are involved in the gravitropism or graviperception. According to statolith theory, a plant distinguishes up from down by means of amyloplast. The statoliths sediment in response to the gravity. In shoots, it is present in starch sheath cells or endodermis cells. It is present in the root tip. Their sedimentation transmit signal for the auxin reorientation and redistribution which ultimately results in upwards growth of stem and downward growth of root.So, the correct answer is 'Amyloplasts'
