Function of photoreceptor?
Photoreceptor can refer to:In anatomy/cell biology:Photoreceptor cell: a photosensitive cell, most commonly referring to a specialized type of neuron found in the retina of vertebrate eyes that is capable of phototransduction;Ocellus (invertebrate photoreceptor): a photoreceptor organ ("simple eye") of invertebrates often comprised of a few sensory cells and a single lens;Eyespot apparatus (microbial photoreceptor): the photoreceptor organelle of a unicellular organism that allows for phototaxis.In biochemistry:Photoreceptor protein: a chromoprotein that responds to being exposed to a certain wavelength of light by initiating a signal transduction cascade;Photopigment: an unstable pigment that undergoes a physical or chemical change upon absorbing a particular wavelength of light;Photosynthetic pigment: molecules involved in transducing light into chemical energy.In technology:Photodetector or photosensor: a device that detects light by capturing photonsPhotoreceptor: the component of a xerographic copier or printer that captures the virtual image that will eventually be printed on paper.
What are phytochrome?
Phytochromes are a type of photoreceptor that is responsive to light in the red to far red range. They are used by plant seeds to determine when to germinate and by plants to set circadian rhythms and tell the season. A phytochrome is a set of 2 of the same protein that are stuck together, with kinase regions at the bottom and photoreceptor regions at the top. They have 2 configurations - one, called Pr, which is receptive to red light, and another, called Pfr, which is receptive to far red light. When a phytochrome receives it's type of light, it switches to the other configuration. In plants, phytochromes are made in the Pr configuration and are active in the Pfr configuration. -L.J.
What do cones cells in your eye allow our eye to do?
Cones are a special type of photoreceptor cell in the retina that allow you to see brighter light than "rods" (a different type of photoreceptor cell), particularly to see color. The brain interprets the response of cones to the different wavelengths of light in order to perceive color in this way.
Which cells on the retina respond to the intensity of light?
Rods function in dim light and provide black-and-white vision. Cones support brighter daytime vision and the perception of color. A third type of photoreceptor, the photosensitive ganglion cell, causes reflexive responses to bright daylight.
What type of microscope is best used to see the organisms in a drop of pond water?

What is the best type of light to use to save energy?
Natural Light
What type of light would the pupil best dilate in?
Blue light.

What type of cells does the eye contain?
Photoreceptor cells and Rod cells are the more known ones. These allow you to see color.
