Plants respond to touch through a process called thigmotropism, where they change their growth pattern in response to physical contact. They use specialized cells called mechanoreceptors to detect touch, which then trigger a series of biochemical signals that lead to changes in growth and movement.
Amoeba typically do not have eye spots, as they are single-celled organisms that lack complex sensory organs. Instead, they rely on other mechanisms, such as chemotaxis, to detect and respond to their environment.
they respond to their environment by using their special sensors.for example, euglena detects light using the special sensors to feed it self.

Plants respond to touch stimuli through a process called thigmotropism, where they change their growth direction in response to touch. This is controlled by hormones like auxin and ethylene, which help regulate cell growth and movement in response to touch. Additionally, plants have specialized cells called mechanoreceptors that detect touch and trigger a cascade of signaling pathways to initiate a response.
stimuli
Paramecium has sensitivity through specialized structures called trichocysts and cilia. Trichocysts can be discharged in response to physical or chemical stimuli, aiding in defense mechanisms. Cilia help the paramecium to detect and respond to changes in its environment, such as light intensity or the presence of food particles.

The receptors that detect heat are known as thermoreceptors and they respond to increases in temperature. Conversely, the receptors that detect cold are also thermoreceptors but they respond to decreases in temperature. These thermoreceptors are specialized nerve endings located in the skin and other tissues of the body.
Living things respond because the normal life form has four main characteristics. Characteristics:-respond-reproduce-grow and develop-made of one or more cellsWithout responding it is no longer called a living thing.
responsiveness
Mechanoreceptors respond to mechanical stimuli such as touch, pressure, vibration, and stretch. They are sensory receptors that detect physical distortions in the environment and convert them into electrical signals that can be interpreted by the brain.
A non-contact type instrument is a device used to measure or sense objects or phenomena without physical contact. These instruments use techniques such as infrared, laser, or radio waves to detect and measure distance, temperature, or other parameters from a distance without touching the object being measured. They are often used in applications where physical contact is not possible or desired.
they respond to their environment by using their special sensors.for example, euglena detects light using the special sensors to feed it self.
They return less salt to the blood by reabsorption.
detect smell
Infrared radiation is used by sensors to detect differences in temperature. Infrared sensors detect the thermal energy emitted by objects in the form of infrared radiation, which allows them to measure temperature variances without physical contact.
Cells on the tongue that detect and respond to different flavors, allowing for the sense of taste.
