WBBSE CLASS 10 LIFE SCIENCE CHAPTER 1 NOTE

MADHYAMIK LIFE CONTROL AND COORDINATION

Control and Coordination in Living Organism |

Madhyamik Life Science Chapter 1 can be classified into five major parts.

• 1. Movement in Plants
• 2. Plant hormones
• 3. Animal Hormone
• 4. Human Eye
• 5. Locomotion in Organism

Movement in plants |

In plants, there are mainly three types of movement.

• 1. Tactic Movement
• 2. Tropic movement
• 3. nastic movement

please watch this video to learn the whole concept.

Plant Hormones/Phytohormones |

In plants, there are mainly three types of hormones.

• 1. Auxin  Hormone
• 2. Giberelin Hormone
• 3. kinin hormone

Animal Hormone |

Animal Hormone is a huge article to cover. In animals, the hormones are classified based on the organs they secret. There are few major organs from where these hormones are secret.

The below video will cover the below topics in the mentioned time
