How Plants Move and Grow: Auxins, Gibberellins, and Ethene Magic!

Plant hormones play crucial roles in regulating growth, development, and responses to environmental stimuli. Auxin phototropism and gravitropism in plants, Role of gibberellins in plant growth and development, and Ethene hormone function in fruit ripening process are key mechanisms that shape plant behavior and development.

  • Auxins control directional growth responses through phototropism and gravitropism
  • Gibberellins regulate various developmental processes including seed germination and fruit development
  • Ethene serves as a ripening hormone particularly important in fruit maturation
  • These hormones work in concert to ensure proper plant growth and responses to environmental cues
  • Understanding these hormones is crucial for agricultural applications and plant science

Key Plant Hormones

The second page introduces the three essential plant hormones that form the core of plant growth regulation. These hormones work together to coordinate various aspects of plant development.

Highlight: The three crucial plant hormones are Auxin, Gibberellins, and Ethene.

Vocabulary: These hormones are also known as plant growth regulators PGRsPGRs.

Auxin Functions and Responses

This page details the complex roles of auxins in plant growth responses. The hormone's involvement in both phototropism and gravitropism demonstrates its versatility in plant development.

Definition: Phototropism is the growth response of plants to light direction, while gravitropism is the response to gravity.

Example: When a plant shoot bends toward sunlight, it's demonstrating positive phototropism due to auxin redistribution.

Highlight: Auxin has opposite effects in shoots and roots - promoting growth in shoots while inhibiting growth in roots.

Gibberellins and Ethene Functions

The final page explores the roles of gibberellins and ethene in plant development and fruit ripening processes.

Definition: Gibberellins are growth-promoting hormones that regulate various developmental processes including stem elongation and seed germination.

Example: Ethene's role in fruit ripening is commercially utilized to ripen fruits like bananas after harvesting.

Highlight: Gibberellins are particularly concentrated in seeds and young leaves, while ethene is a gas that can affect neighboring plants.

Quote: "Ethene is used in the food industry to trigger the process of ripening, after the fruit have been picked, and before they reach the shop shelf."

Introduction to Plant Hormones

This introductory page establishes the foundation for understanding plant hormones and their various functions in plant growth and development. Plant hormones are chemical messengers that regulate numerous aspects of plant life cycles.

Definition: Plant hormones are naturally occurring compounds that regulate plant growth and development at extremely low concentrations.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Samantha Klich

Android user

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

David K

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

very reliable app to help and grow your ideas of Maths, English and other related topics in your works. please use this app if your struggling in areas, this app is key for that. wish I'd of done a review before. and it's also free so don't worry about that.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
