Why is the middle of a sunflower yellow?

Within the sunflower center are even more individual flowers called disk flowers. Once pollination has occurred these disk flowers in the sunflower center will produce seeds, a process that makes the center of the sunflower head appear darker.

Which is correct for sunflower root?

What kind of root system does a sunflower have?

If grown in compacted soil, the sunflower may develop a shallow and more horizontal root system, resulting in its reduced ability to absorb nutrients and moisture deeper in the soil. A lack of nutrients and sufficient water in turn weaken the plant, making it more susceptible to disease or damage by insects.

How does germination occur in a sunflower plant?

After the seed has been planted germination starts to happen. This is the first stage of the seeds awakened life. Underneath the soil, out of sight, the wispy roots reach out and a developing shoot pushes its way to the surface of the soil, looking for sunlight. When this shoot appears we know we’re on our way to growing a sunflower. Stage 3.

Can a sunflower be pulled up by the roots?

Sunflowers can be difficult to pull up by the roots, and the strong taproot is often longer than the plant stalk above ground. The common sunflower (Helianthus annuus) grows naturally across North America as an annual and may be considered a weed in some states. You may need to cut the stalk flush with the ground to remove the plant.

What happens in the life cycle of a sunflower?

The sunflower goes through five stages during its life cycle. The germination phase begins the sunflower’s life. The vegetative phase then takes place when the plant grows leaves. Soon after, the reproductive phase occurs, and the bud of the flower forms.
