What type of plant is a sunflower?
A sunflower (Helianthus annuus) is a flowering annual and is a dicot.
That depends on the person... Hey wait, did you mean the cold 'cool' or great 'cool'?
What types of plants grow better in artificial light a nasturtium or a sunflower?
Both of these flowers require full sunlight to bloom, something which artificial lighting just cannot duplicate without considerable expense (a high-intensity UV growing setup might do the trick). That's not to mention the space required: sunflowers can grow up to 12 feet in height, and even dwarf nasturtium will spread to 30". Unless you are blessed with a commercial greenhouse or a two-story, south-facing atrium, attempting to grow these beauties indoors will only disappoint.
What are sunflowers used for in farming?
use them on farmtown there the best but not as good as onions or pinapples
Who is painter rossy signed painting of sunflowers circa 1960?
The painter associated with the signed painting of sunflowers circa 1960 is likely Vincent van Gogh, who is renowned for his iconic sunflower series. However, if you are referring to a contemporary artist named Rossy, there may be limited information available, as details on less widely known artists can vary. In this case, it's important to clarify whether you are speaking of a specific modern artist or a reproduction of van Gogh's work.
Is a sunflower heliotropic and why?
Yes, sunflowers are heliotropic, meaning they turn their heads to follow the sun's movement across the sky. This behavior is particularly evident in their early growth stages, helping them maximize light exposure for photosynthesis. The phenomenon is driven by differential growth on the sides of the stem, which causes the flower to tilt towards the sunlight. However, once sunflowers mature and their flowers bloom, they generally face east and remain fixed in that position.
How much sunflower has nectar?
Sunflowers are known to produce a significant amount of nectar, attracting various pollinators like bees and butterflies. On average, a sunflower can produce about 0.5 to 1 milliliter of nectar per flower, depending on factors such as plant health, environmental conditions, and the specific sunflower variety. The nectar is typically most abundant during the peak blooming period, providing a valuable food source for pollinators.
What part of a sunflower is the reproductive?
The reproductive parts of a sunflower are primarily found in the flower head, specifically within the disk and ray florets. The disk florets, located in the center, contain the male reproductive organs (stamens) and female reproductive organs (pistils). The ray florets, which are the yellow petal-like structures surrounding the disk, are typically sterile but attract pollinators. Together, these components facilitate the plant's reproduction through pollination and seed production.
What did Mr Sir make out of a sunflower seed sack?
Mr. Sir made a backpack out of a sunflower seed sack. This inventive creation reflects his resourcefulness and ability to repurpose materials in the harsh environment of Camp Green Lake. The backpack symbolizes both survival and the harsh realities faced by the boys at the camp.
What is the best soil type for sunflowers?
Just about any soil which drains well and is rich in macronutrients but poor in salt accumulation is the condition which sunflowers (Helianthus annuus) seek.
Specifically, this North American native plant accepts just about any combination of clay, sand or silt which does not leach nutrients on the one extreme or pool on the other. It does not tolerant nutrient loss, salt build-up, or waterlogging. It particularly flourishes with soils which already have, or which are fed, the six major nutrients calcium, magnesium, nitrogen, phosphorus, potassium, and sulphur.
No, not all sunflower seeds have the same length and thickness; they can vary based on factors like the specific sunflower variety, growing conditions, and genetic traits. Different seed sizes and shapes can influence germination rates, growth patterns, and resilience to pests. Additionally, variations can be an evolutionary adaptation to optimize survival and reproduction in diverse environments. These differences ultimately contribute to the overall diversity within sunflower species.
How does sunflowers help other organisms?
Sunflowers provide numerous benefits to other organisms, primarily through their role in ecosystems. They serve as a vital food source for pollinators like bees and butterflies, attracting them with their bright blooms and nectar. Additionally, their seeds offer nourishment for birds and small mammals. Beyond direct benefits, sunflowers also contribute to soil health by improving nutrient content and preventing erosion with their extensive root systems.
