Answer:
Porifera or Sponges
Explanation:
Porifera is the phylum of the simplest multicellular marine animals. Their body is composed of two cell layers (something like tissues) and mesophyl between them. The body is in direct contact with surrounding water through the large number of pores and channels. What makes Sponges so simple is that their cells are unspecialized and that they don't have nervous, digestive or circulatory systems.

Explanation:
If you apply white light and it reflects only red, you see it red, all the other wavelentghs absorbed. If it reflects all wavelength (i think listed all red-orange....) then it should be white.
Diffraction could have caused it. This is where a wave encounters an obstacle or a slit. It happens when there is bending of light around the corners of an obstacle. It is often described as the interference of waves according to the Huygens–Fresnel principle.
