The photoreceptor inside retina is the receptor of light that makes an organism capable to see. The photoreceptor consists of cone cells that can distinguish color and rod cells that can distinguish color as black and white image.

There are three kinds of cone cells, red, green and blue. The interaction of stimulus given by these 3 kinds of cone cells gives the perception of color. In color-blind patient, some of the cone cells are damaged or not formed. Losing the cone cells will cause color blind patient unable to perceive color. To have a good visual acuity, you don't need all the cone cells variety, only one kind is enough.

natita [175]

Answer:

Answer B. Endosymbiosis

Explanation:

Early protists were first eukaryotic organisms and had several membrane bound organelles. The anaerobic protists evolved by acquiring purple bacteria. The purple bacteria have the ability to carry out aerobic cellular respiration. The endosymbiont transformed into mitochondria in due course of evolution. Similarly, the photosynthesizing protists were evolved by endosymbiosis of cyanobacteria which in turn was transformed into chloroplast during further evolution.

The cells which are required in large amounts are called as macronutrients, while the ones required in small quantities are called as micronutrients, or trace elements.

Hence, the answer is trace elements or micronutrients.
