When you are exposed to bright light, cells in the retina detect the stimulus and send it to the brain for processing. The brain commands the iris to constrict and decrease pupil size.
The structure that serves as a receptor in this system is Retina
<h3>How can we see the object?</h3>
Organisms adapted and evolved the eyes to see the surrounding environment. This ability to see begins when the visible wavelength of light enters the eye through a transparent covering called Cornea. The light enters the cornea and enters the inner of the eye through a round hole known as the pupil.
The light rays then enter the convex-shaped lens in the eye which focuses the beam of light on the back of the eye in the region of the tissue called the retina. The retina contains the photoreceptor cells-rods and cones in which the cone cells have the ability to detect three wavelengths of light especially blue, green and red which help us see various versions of the colour.
These cells convert light energy to chemical energy in the form of the action potential which gets transmitted to the part of the brain associated with the vision. This completes the pathway of the vision.
Thus, Retina is the answer.

Adaptations can give an organism a competitive edge but adaptations are not always used for completion against other species
The cluster of cells in the ovule of a fertilized flowering plant that has not yet formed into an embryo is called a proembryo.
<h3>What is a proembryo? </h3>
It is a structure that is developed after the egg is segmented and the formation of the true embryo is yet to take place.
After the egg and the sperm nuclei are fertilized, the apical and basal cells are formed after cell division. The cell division is asymmetrical in the case of monocot and transverse in the case of divots.
Apical cells turn into the proembryo and eventually the embryo. This development is supported by the suspensor cells from the basal cells.
Therefore, the cluster of cells in the ovule of a fertilized flowering plant that has not yet formed into an embryo is called a proembryo.
