name four response system for plants and animal in life science
1. Nervous system: This system is responsible for transmitting signals and coordinating responses in animals. It includes the brain, spinal cord, and peripheral nerves.
2. Endocrine system: This system consists of glands that secrete hormones, which regulate various physiological processes in animals and plants. Hormones are chemical messengers that travel through the circulatory system to target cells or tissues.
3. Immune system: This system protects plants and animals from pathogens, such as bacteria, viruses, and fungi. It includes various components, such as white blood cells and antibodies, which work together to identify and destroy harmful invaders.
4. Tropism in plants: Tropism is a response mechanism in plants that allows them to react to external stimuli and adapt to their environment. Examples include phototropism (growth towards light), gravitropism (response to gravity), and hydrotropism (response to water). These responses help plants optimize their growth and survival.
