Sunflowers

| Captured October 26th along the driveway behind my home. |
Sunflowers are known for their ability to track the movement
of the sun throughout the day, a behavior known as heliotropism. This movement
allows them to maximize their exposure to sunlight, which is essential for
photosynthesis, the process by which plants convert sunlight into energy to
fuel their growth.
Sunflowers are able to move to keep facing the sun through a combination of differential growth driven by auxin accumulation, circadian rhythms, and the reversible nature of their heliotropic behavior. This adaptation allows them to efficiently capture sunlight for photosynthesis and ultimately thrive in their environment.

I think we can learn something from sunflowers.
ReplyDeleteHello John,
ReplyDeleteSunflowers are one of my favorite flowers. It is neat how they follow the sun, so they can always face toward the sunshine. Great post, thanks for sharing the info. Have a great weekend.
Hoi John,
ReplyDeleteVery nice. I have them in my garden too.
Have a nice day.
Hello John :=)
ReplyDeleteFascinating post and beautiful photo. I knew, as most people know that Sunflowers face the sun, and move their heads towards the sun as it changes direction but I did not know this is known as heliotropism, and this allows them to capture sunlight for photosynthesis. I have always enjoyed seeing their upturned faces and it gives me happiness to see their bright yellow flowers, but how extraordinary that auxin, a plant hormone plays such a large part in regulating their tall growth, and also circadian rhythem ( I had to look both these things up) present in animals and plants serves as a biological clock, I think! Now I leave you with more knowledge than when I arrived, so many thanks John.
Enjoy the rest of your weekend
All the best
Sonjia.
I also knew they followed the sun, but didn't know why. Thanks for making me a little smarter today, John.
ReplyDeleteSuch a beautiful picture of the sunflower.
ReplyDeleteI love how they follow the sun.
Love those incredible flowers. We are watching one in our garden develop seeds. The birds will enjoy them for sure.
ReplyDeletesimple process but very few people know about it.
ReplyDeleteHi John, I am blown away by the beauty of your sunflower photo. It says it all, as their golden faces look towards the sun itself. I also love the sky watch photos of your previous post. How fortunate to live where the beauty of sunrises and sunsets may greet you on your walks. You've brightened my day :)
ReplyDeleteI did not know those facts about sunflowers! Your sunflower photo is beautiful! A couple of years ago when I was learning to draw sunflowers, I read lots about their symbolism and I see all that in your photo.
ReplyDeleteWhat a delightful post dear John!
