Control and Coordination in Animals and Plants Notes

The chapter Control and Coordination explores how organisms respond to stimuli in their environment. It covers the mechanisms and systems used for coordination in both plants and animals, including hormones and the nervous system.

‍

Control and Coordination in Plants

Plants respond to external stimuli like light, gravity, water, and touch through tropic movements and the action of plant hormones.

Tropic Movements

Tropic movements are directional responses of plants to stimuli. They can be either towards (positive) or away (negative) from the stimulus.

‍

Plant Hormones

Plant hormones regulate growth and responses to stimuli.

‍

Control and Coordination in Animals

In animals, control and coordination are achieved through the nervous system and hormonal regulation.

Nervous System

The nervous system is responsible for receiving, processing, and responding to stimuli.

Structure of the Nervous System:

Central Nervous System (CNS):‍

Brain and spinal cord.

Processes information and sends commands.

Peripheral Nervous System (PNS):

Nerves connecting the CNS to the rest of the body.

Divided into:

Somatic Nervous System: Controls voluntary actions (e.g., moving a hand).

Autonomic Nervous System: Controls involuntary actions (e.g., heartbeat).

Key Components of the Nervous System:

• Receptors: Detect stimuli (e.g., eyes for light, skin for touch).

• Neurons: Nerve cells that transmit signals.

• Effectors: Organs or tissues (e.g., muscles, glands) that respond to commands.

Types of Actions:

1. Voluntary Actions:

Under conscious control.

Example: Writing, walking.

2. Involuntary Actions:

Not under conscious control.

Example: Heartbeat, digestion.

3. Reflex Actions:

Automatic and immediate response to stimuli.

Example: Pulling your hand away from a hot object.

Reflex Arc: Pathway of a reflex action: Stimulus → Receptor → Sensory neuron → Spinal cord → Motor neuron → Effector → Response.

The Brain:

The brain is the control center of the nervous system.

3. Chemical Coordination in Animals

Hormones play a vital role in controlling and coordinating activities in animals. They are secreted by endocrine glands and act as chemical messengers.
