Sunflowers

Sunflower extract contains a variety of compounds, including phenolic acids (such as chlorogenic acid), flavonoids (such as quercetin), tocopherols (vitamin E), and fatty acids (such as linoleic acid). These compounds are known for their antioxidant and anti-inflammatory properties.

First of all:yes because they are organic

and yes again because all seeds decay.

A sunflower exhibits heliotropism by following the sun's movement to maximize sunlight absorption. It also displays phototropism by growing toward light sources for optimal photosynthesis. Lastly, sunflowers can adjust their leaf angle throughout the day to capture more sunlight.

Yes, sunflowers are dicotyledonous plants, meaning they have seeds with two embryonic leaves (cotyledons) when they sprout. Dicotyledonous plants are characterized by various features, including branching veins in their leaves and flower parts in multiples of four or five.

Yes, sunflowers are native to North and South America and can be found growing wild in various regions. They are adaptable plants that can thrive in a variety of environments, from open fields to roadsides.

Yes, a sunflower is vascular. It has a system of vessels that transport water, nutrients, and sugars throughout the plant. These vessels include xylem for water and mineral transport and phloem for sugar transport.

The average yield per acre of sunflower seeds can vary depending on factors such as variety, growing conditions, and farming practices. On average, a well-managed sunflower crop can yield between 1,000 to 1,500 pounds of seeds per acre. However, yields can be lower or higher based on specific circumstances.

For the oil type of sunflower seed, there are 24-32 pounds per bushel. So if a ton equals 2000 pounds, then there are between 83 and 63 bushels per ton of sunflower oilseed.

For the confectionery sunflower seeds (used for food) there are 24 pounds per bushel, so that would be 83 bushels per ton.

Another name for the sunflower is Helianthus, which comes from the Greek words "helios" (sun) and "anthos" (flower). It is also commonly known as the Common Sunflower.

There are about 70 species of sunflower, the more common domestic varieties flower in late spring, summer and into early autumn

Yes, sunflowers appear yellow because they reflect yellow light. The petals of the sunflower absorb all colors of light except for yellow, which is reflected back to our eyes, making them appear yellow.

A seed protector is a covering or barrier that helps shield seeds from harsh environmental conditions such as extreme temperatures, pests, or diseases. It can be a physical covering, like a seed coat, or a chemical protection mechanism within the seed itself.

The sunflower generally symbolizes adoration, loyalty, and longevity. It is also associated with positivity, strength, and growth due to its characteristic of following the sun's path throughout the day.

The basics of it is that sunflower seeds get dropped all the time but usually land on hard ground and never make it under the soil. By highways and dirt roads and the edge of planted crop fields the soil gets turned over quite often, therefore putting the seed in the ground.

Sunflowers typically require about 1 to 1.5 inches of water per week. The water needs may vary depending on the stage of growth, weather conditions, and soil moisture levels. It is important to avoid overwatering as it can lead to root rot.

No. In fact, roasted sunflower seeds are a popular snack.

http://www.seattlecentral.org/qelp/sets/009/009.html has a growth chart showing the height of a sunflower on various days.

In general, questions about growth rates must specify the time interval. Is the question about the first 30 days of the sunflower's life or the days between 60 and 90? The answer would be very different.

From the data at the link above, for the first 28 days, the growth rate is 3.5 cm per day. For the days betwen 63 and 84, the growth rate is 0.35 cm per day, or about 1/10 the growth rate during the first 28 days.

Sunflower seeds are rich in oil because they are rich in poly-unsaturated fatty acid and mono-unsaturated oleic acid. Sunflower seed oil is extracted from the seeds by pressing them with great pressure.

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.

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.

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.

The tallest sunflower measured 30 feet and 1 inch and was grown in Germany in 2014.
