They are a type of photoreceptor in the retina responsible for color vision. There are three types of cones; blue, green and red mainly packed in the fovea. The other type of photoreceptor is the rods responsible for black and white vision and are mainly located in the peripherals of the retina. Rods can perceive dim light, unlike cones.
Is called lurpus nephritis
A eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes. However, unlike prokaryotic cells, eukaryotic cells have: a membrane-bound nucleus. numerous membrane-bound organelles (including the endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria) and the surface to volume ratio is the amount of surface area per unit volume of an object or collection of objects. In chemical reactions involving a solid material, the surface area to volume ratio is an important factor for the reactivity, that is, the rate at which the chemical reaction will proceed.
