Why don't the paramecium and amoeba not have eyespots?

Answer 1

Paramecium and amoeba do not have eyespots because they rely on different mechanisms for sensing their environment. While eyespots are typically used by some single-celled organisms, like certain algae, to detect light and navigate towards or away from it, paramecium and amoeba primarily use their cilia and pseudopodia, respectively, to respond to chemical gradients and physical stimuli. Their locomotion and feeding strategies are adapted to their environments, making specialized light-sensing structures unnecessary. Instead, they are more focused on their ability to move and capture food based on chemical cues.
