Plant hormones and chemical fertilizers

This is a video that explores the fascinating world of plant hormones, also known as phytohormones. These are chemical messengers that regulate all aspects of plant growth and development, from germination to flowering and fruiting. We'll delve into the five main classes of plant hormones:

Auxins: We'll demonstrate how auxins are responsible for cell elongation and phototropism (a plant's ability to grow towards a light source). You'll see an experiment showing a plant bending towards a window.

Gibberellins: This segment will focus on the role of gibberellins in promoting stem elongation and germination. We'll compare a plant treated with gibberellins to an untreated one to highlight the dramatic difference in growth.

Cytokinins: Discover how cytokinins promote cell division and are key to bud formation. We'll showcase their role in tissue culture and how they prevent leaf aging.

Abscisic Acid (ABA): Learn about this "stress hormone" and its function in inhibiting growth and closing stomata during drought. We'll visualize how ABA helps a plant conserve water.

Ethylene: Finally, we'll cover this gaseous hormone, famous for its role in fruit ripening and senescence (aging). You'll see a time-lapse video of a tomato ripening with the help of ethylene.

This video is perfect for students, teachers, and anyone curious about how plants work.
