These are called receptors. They can be of many different types, depending on what they perceive.
Photoreceptors: Pick up light - like your eyes
Chemoreceptors: Detect chemicals - like your nose and tongue
Haptic receptors: Detect touch - like your skin

This is called sensory responses, where animals use specialized cells called sensory receptors to detect and respond to various external stimuli in their environment. These receptors are responsible for detecting light, sound, touch, taste, and smell, and help the animal navigate and interact with their surroundings.
Many flatworms can detect changes in the amount of light in their environment using groups of cells called photoreceptors. These cells are sensitive to light and help the flatworms navigate and respond to their surroundings based on light levels.
No, T cells respond to antigens by directly destroying infected cells or by producing cytokines to help coordinate the immune response. Complements are a group of proteins that are part of the innate immune response and are mainly secreted by macrophages and other immune cells to help enhance the immune response.
Mitochondria are known as the powerhouse of the cell and are found in eukaryotic cells, which include cells in animals, plants, fungi, and protists. Mitochondria play a crucial role in producing energy in the form of ATP through the process of cellular respiration.

No, trees do not have nerves like animals or humans. Trees do have a complex network of cells and tissues that help them sense and respond to their environment, but they do not have a central nervous system like animals do.
Vertebrate animals use the nervous system to help them respond to their environment. This system includes the brain, spinal cord, and peripheral nerves, which work together to process sensory information and coordinate appropriate responses to stimuli in the environment.
Cells are the basic structural and functional units of living organisms. They provide structure, process nutrients, and carry out essential functions for the organism to survive and function properly. Cells also help organisms grow, reproduce, and respond to their environment.

worms
Animals also help the environment

you help the environment and animals. you can also help other people.
Green Peace has a goal to make the world a better place.They help endangered animals, the environment ect. ect.
Yes, oysters have a simple nervous system that allows them to respond to their environment. However, it is much less complex than the nervous systems of other animals, such as mammals. Oysters lack a centralized brain and instead have a network of nerve cells that help them detect and react to stimuli like changes in water temperature or predators.
