L10 Plant & Animal Nervous System w/ Sensory & Nervous Mech

Cards (29)

  • The nervous system is responsible for coordinating and controlling the activities of organisms.
  • Plant Nervous System: Plants do not have a centralized nervous system like animals. Instead, they have a decentralized network of cells that can transmit electrical signals. This network is known as the plant's "nervous system. "
  • Plant Nervous System, Main Components: Sensory Cells, Electrical Signaling, Chemical Signaling
  • Plant, Sensory Cells: Plants have specialized cells called "sensory cells" that can detect various stimuli such as light, gravity, touch, and chemicals.
  • Plant, Sensory Cells: These cells are usually located in the roots, stems, leaves, and flowers of the plant.
  • Plant, Sensory Cells: Photoreceptors like phytochromes, cryptochromes, phototropins and UV-B receptors.
  • Plant, Electrical Signaling: When a sensory cell detects a stimulus, it generates an electrical signal. This signal can travel through the plant's interconnected cells, allowing the plant to transmit information from one part to another.
  • Plant, Chemical Signaling: Plants also use chemical signals, such as hormones, to communicate and coordinate their responses. These chemical signals can be produced in one part of the plant and transported to other parts to trigger specific responses.
  • Animals have a centralized nervous system, which consists of the brain, spinal cord, and nerves. The animal nervous system can be divided into two main parts: Central Nervous System (CNS) and the Peripheral Nervous System
  • Central Nervous System (CNS): includes the brain and spinal cord.
  • Central Nervous System (CNS): It is responsible for processing and integrating information received from the sensory organs and coordinating the body's responses.
  • Peripheral Nervous System (PNS): The PNS consists of nerves that connect the CNS to the rest of the body.
  • Peripheral Nervous System (PNS): It transmits signals between the CNS and various organs, muscles, and glands.
  • Sensory Mechanism in Plants and Animals: Both plants and animals have sensory mechanisms that allow them to detect and respond to stimuli in their environment.
  • Sensory Mechanism, Plants: Plants have sensory cells distributed throughout their tissues.
  • Sensory Mechanism, Plants: Sensory cells in plants can detect stimuli such as light, gravity, touch, and chemicals.
  • Sensory Mechanism, Plant: Plant sensory cells generate electrical signals in response to stimuli.
  • Sensory Mechanism, Plant: Plants use chemical signals, such as hormones, to coordinate their responses.
  • Sensory Mechanism, Animal: Animals have specialized sensory organs, such as eyes, ears, nose, and skin, dedicated to detecting specific stimuli.
  • Sensory Mechanism, Animal: Animal sensory organs convert stimuli into electrical signals that can be processed by the nervous system.
  • Sensory Mechanism, Animal: Animals have a wide range of sensory abilities, including vision, hearing, smell, taste, and touch.
  • Nervous Mechanism, Plants: Plant nervous system is decentralized, with interconnected cells transmitting electrical signals.
  • Nervous Mechanism, Plants: Electrical signals in plants can travel in any direction and can be transmitted through the entire plant.
  • Nervous Mechanism, Plants: Plants use chemical signals, such as hormones, to coordinate their responses.
  • Nervous Mechanism, Plants: Plant responses to stimuli are generally slower compared to animals.
  • Nervous Mechanism, Animal: Animal nervous system is centralized, with the brain and spinal cord processing and integrating information.
  • Nervous Mechanism, Animal: Nerves in animals transmit electrical signals in a specific direction, from sensory organs to the CNS and from the CNS to muscles and glands.
  • Nervous Mechanism, Animal: Animal responses to stimuli are generally faster compared to plants.
  • While plants and animals have different nervous systems and sensory mechanisms, both have evolved unique ways to detect and respond to their environment. Plants rely on a decentralized network of cells and chemical signaling, while animals have a centralized nervous system and specialized sensory organs.
