Which of the following information about photoreceptors is false?a. They have inner and outer segments.b. The segments are connected by a cilium.c. They are located in the retina.d. Cones are more senstive to light than rods.e. Visual pigments in the rods are called rhodopsin.

Which of the following is true?a) There are no rods on the fovea.b) Cones work better under low light.c) The blind spot has a lot of cones.d) Isomerization does not influence photoreceptor membrane potentials.e) Fovea has no photoreceptors.f) Visual pigments in rods are called photopsin

Which of the following information about Photoreceptors is incorrect?A) When exposed to light, retinal changes its shape (isomerization).B) Under prolonged exposure to light, retinal detaches from opsin (visual pigment bleaching).C) Opsin and retinal should be attached again in order to reach to the light.D) When visual pigments are bleached, they cannot react to the light anymore.E) Photoreceptors become more responsive to the light due to prolonged exposure to the light.

There are two types of photoreceptors, rods and cones. State which one is responsible for the detection of colour.

Which one is false about neurons in the eye?A) Photoreceptor converts light energy to neuronal signal.B) Photoreceptors send signals to ganglion cells.C) Bipolar cells send signals to ganglion cells.D) The signaling from photoreceptors to bipolar cells, bipolar cells to ganglion cells isunidirectionalE) There are horizontal cells and amacrine cells on the retina

The photoreceptors that are involved in color vision and visual acuity are , whereas the photoreceptors that are involved in noncolor vision and vision under conditions of low light are .
