Question
Does the Venus flytrap know whether a stick would make a good meal? Why or why not? A 7 Yes, because the stick does not taste good. B 7 No, because the stick is too small for the plant to notice it. C 7 No, because the plant does not have a brain. D 7 Yes, because the plant can feel it moving around.

The correct answer is D. The Venus flytrap does not "know" whether a stick would make a good meal in the sense of having knowledge or preferences. Instead, it responds to the physical interaction of the stick with its trigger hairs by closing its trap. This is a survival mechanism evolved to capture prey, and it does so based on the physical interaction (touch) rather than any cognitive assessment.
Explicação
## Step 1The Venus flytrap is a type of carnivorous plant that feeds on small insects and arachnids. It has evolved to detect the presence of prey through touch-sensitive trigger hairs located on its inner surfaces. When an insect or spider touches these hairs, the plant quickly closes its trap, capturing the intruder. The plant then produces digestive enzymes to break down the prey.## Step 2Option A suggests that the Venus flytrap can determine if a stick would make a good meal based on taste. However, plants do not have taste receptors like animals. They respond to stimuli such as touch, light, and chemical signals, but not taste.## Step 3Option B suggests that the stick is too small for the plant to notice. This is not accurate because the Venus flytrap can detect the touch of even small prey. The size of the stick is irrelevant if it makes contact with the trigger hairs.## Step 4Option C states that the plant does not have a brain. While it's true that the Venus flytrap lacks a central nervous system and brain, this is not the reason it cannot determine if a stick would make a good meal. Plants, including the Venus flytrap, can respond to environmental stimuli without a nervous system.## Step 5Option D suggests that the plant can feel it moving around. This is the most accurate option. The Venus flytrap can detect movement and touch. When a stick or any object touches its trigger hairs, the plant responds by closing its trap. This response is a mechanism to capture prey, indicating that the plant can sense movement and touch, albeit in a simple and primitive way compared to animals.
