How does the Sunflower track the sun?
No-one really knows the exact mechanism for 'heliotropism' -or sun tracking.It appears that an external factor ( the sun) is triggering a not -yet understood factor within the plant.It is still being researched.
Heliotropism is the term used to describe the tracking of the sun by the flower buds of sunflowers. Other plants also have flowers and/or leaves that track the sun. First, let's discuss how the plants are able to track the sun. There is a collection of specialized cells at the base of the flower bud or leaf called a pulvinus that carry the "motor" cells that enable the plant leaf or flower to track the sun. These cells enlarge or shrink according the turgor pressure from the water inside them. In response to blue wavelength light, potassium ion concentration increases in the "motor" cells on the shadow side of the pulvinus. With the increase of potassium ions the osmotic potential in the cells becomes more negative and the cells absorb more water and elongate, turning the face of the flower to the sun.
Unfortunately, as well as being among the more intelligent creatures, the parrot clan are also among the most stubborn -- and are well-equipped to show it, as you know.
Try weaning him off by SLOWWWWLY reducing the amount. Or consider not worrying about it. What does your vet say? Are the seeds bad for him, or are you just tired of the mess? Reply:: He hasn't been to the vet in a while. They told me along with where I got him sunflower seeds are bad for birds because (1) they become addicted to them (2) they are very high in fat. : Unfortunately with my job situation and a lack of adequate bird stores in my area I had to buy his food at walmart. Which in turn is LOADED with sunflower seeds (because they are so cheap) and now Im paying for it dearly. : I am trying the slow weaning process, but the screaming is horrible. My cat actually screams back at him. He knows when he is out of sunflower seeds and screams accordingly. I've been trying to cut down on replacing the food, because all of the rest of the seed is still there. : I have the only sun conure I know of that doesnt like fruits/vegetables. He doesnt eat pellets and only has certain chew toys!! Lol.. I got a picky bird!
The sunflower is a plant, and all plants belong to the taxonomic domain of Eukarya.Eukarya covers all organisms in the Kingdom Plantae, as well as the Kingdoms Animalia, Fungi and Protista.
What is the scientific method of sunflower?
The scientific method involves making observations about sunflowers, formulating a hypothesis to explain these observations, designing and conducting experiments to test the hypothesis, analyzing the data collected, and drawing conclusions based on the results. This process is iterative and may involve refining the hypothesis or conducting further experiments to gain a deeper understanding of sunflower biology or behavior. Ultimately, the scientific method is a systematic approach to investigating and understanding the natural world.
Short answer: the sunflower IS an angiosperm (flowering plant).
Here is the taxomomy (classification) of a sunflower:
- Kingdom: Plantae -it is a plant
- Subkingdom: Tracheobionta - it is a vascular plant
- Superdivision: Spermatophyta - it is a seed plant
- Division: Magnoliophyts - Flowering Plants (this is the division of Angiosperms)
- Class: Magnoliopsida - dicotyledons
- Subclass: Asteridae (aster is Latin for "star" - these flowers are star-shaped)
- Order: Asterales
- Family: Asteraceae
- Genus Helianthus (heli = sun + anthus = flower)
yes.
How tall is the tallest sunflower in the world and where was it grown?
The tallest sunflower measured 30 feet and 1 inch and was grown in Germany in 2014.

How tall is the average of the sunflower?
I have seen 8 foot sunflowers.

There are so many different kinds of sunflowers, you have edible ones, you have those for decorative and also the ones you plant for the wild life. I just planted the TEDDY BEAR, which is a softer fuller looking, 4-5 foot height.
So an average height would be 5-8 foot, this being of your general garden variety seed stock.
Stock seeds planted for food oil does not need height to be a good plant. In fact, hybrids of crops for food consumption not using the stock for food or silage, can be shorter than previous years. Example: the new field corns being planted are for faster growth, shorter, less waste. So a 5 foot stalk of corn, versus 8-9 foot increases your yield per acre.
How many sunflower seeds come in a bag?
Probably very few. Sunflower heads are processed at the factory producing the sunflower seeds by the thousands, and in washing, sorting, etc, a great deal of "mixing" takes place. A bag of sunflower seeds probably has seeds from dozens/hundreds of heads in it.
Are sunflowers angiosperms or gymnosperms?
The flowering plants (angiosperms) are also known as Angiospermae or Magnoliophyta. There are more than 250,000 of these seed producing plants. YES, sunflowers are included.
Characteristics of Angiosperms:
- Flowers (the thing that sets angiosperms apart from all others)
- Stamens (specialized to attract pollinators & modified to prevent self-fertilization)
- Smaller sized pollen (than the gymnosperms)
- Closed carpel (cuts down on self-fertilization and increases genetic variablity)
- Smaller sized "egg" (than the gymnosperms)
- Endosperm (nutritive tissue for embryo, cotyledons & seedling)

Who many sunflowers is there in the world?
True sunflowers belong to the genus Helianthus, of which there are 52 known species.
How many times should you water sunflowers?
it depends on the color of the flower. If it is normal green then just water it whenever it is dry. But if it is yellow that means that you are drowning it
By "red dirt", if you mean the iron tinted red clay of the Southern Piedmont areas, then I can certainly testify that YES, sunflowers do grow in red dirt.
If you mean the red dirt of the Western regions, then I should mention that the upper state areas between the Mississippi River and the Rocky Mountains produce the largest yields of sunflower seed oil in the country. It's a magnificent thing to see acres and acres of sunflowers in full bloom.
Yes Sunflowers can be drilled with a precision drill like Great Plains, Sunflower Mfg, Landpride. JD etc. provided they can accurate meter down to maintain a planting rate of no more than 5# / acre. Pre-emergent herbicides are a necessity since they can't be cultivated after planting.
How does a sunflower defend itself?
A sunflower does defend itself against other plants who would attempt to steal nutrients, water or light from its soil space. This is call allelopathy, and all plants have it to some degree, but sunflowers are infamous for it. It has been studied at the university level in an attempt to control weeds in a crop using the sunflower's natural toxins (poisons) versus manufactured weed killers.
What foods are sunflowers used in?
Foods made from sunflowers include margarine, oil, sunflower butter and bread. The seeds can be used as a snack food or as a garnish.
Products made from sunflowers (Helianthus annuus) include the following:
- Seeds - as a food used raw, baked, roasted, salted or not salted.
- Seeds - can be used for feeding seed-eating birds.
- Seeds - can be made into butter (like peanut butter) or made into bread.
- Seeds - oil is extracted for cooking, margarine and biodiesel.
- Seeds - when oil is extracted, the remaining "cake" can be used for cattle food.
- Flower - ornamental plant for flower or vegetable gardens.
- Plant - produces latex and may be source for nonallergenic rubber.
- Stem - contains a fiber that can be used in paper production.
- Leaves - can be used for cattle feed.
- Roots - used in phytoremediation to extract poisons from the soil.

What is the sunflowers division name?
head
Answer:
First, the "Sunflower" is native to the Americas.
The sunflower is comprised of many smaller flowers very close together, forming what is known as florets. These florets as a whole is called the head or flower of the sunflower. The florets, spiral forming the flower/head and can grow to as large as 15" (381mm) in diameter and up to 15 feet (4.57M) tall.
What happens if rabbits eat sunflower seed shells?
They could suffer from a case of advanced felinelukimia
