Answer:
The correct answer is "phototropism".
Explanation:
The biological behavior of plants to bend towards the light is called phototropism. If plants failure to perform this behavior is an example of the plants inability to perform phototropism. The molecules that regulate phototropism are the auxins, which bring flexibility to the plant cell's wall and make plants growth towards the light by moving to the darker side of the plant.
Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows.
Here you go, and i hope you have a good day too :)

Answer;
-Pellicle
Explanation;
-Protist cells may contain a single nucleus or many nuclei; they range in size from microscopic to thousands of meters in area. Protists may have animal-like cell membranes, plant-like cell walls, or may be covered by a pellicle.
-On a paramecium's exterior is found the pellicle. The pellicle is stiff to maintain the paramecium's shape and provide stability but it is also flexible to allow movement. It also acts as an attachment site for external organelles such as cilia.
