yes, hibiscus has epicalyx. its is the modified form of bracts.

Yes, hibiscus plants contain chlorophyll. Chlorophyll is a pigment found in the chloroplasts of plant cells and is essential for photosynthesis, the process by which plants convert sunlight into energy.
Hibiscus flowers contain a variety of chemical constituents such as anthocyanins, flavonoids, polysaccharides, organic acids, and vitamins that contribute to their antioxidant and health-promoting properties. These compounds also give hibiscus flowers their vibrant colors and distinct flavor.
Hibiscus flowers are considered complete flowers because they contain all four main floral parts: sepals, petals, stamens, and pistils.
While hibiscus kenaf (Hibiscus cannabinus) is related to cannabis, it does not contain the same psychoactive compounds. Smoking it would not produce the same effects as smoking marijuana. It is generally not recommended to smoke hibiscus kenaf as it may produce harsh smoke and could be harmful to your health.
The gumamela is usually more well-known as the hibiscus, as gumamela is the Filipino name. Like most plants, the petals of the flower are the source of fragrance for the hibiscus.
To maintain turgor pressure, cells in both the leaves and stems of non-woody or herbaceous plants contain a high concentration of water within their vacuoles. This water creates internal pressure against the cell wall, keeping the plant rigid and upright. Additionally, the presence of solutes, such as sugars and salts, helps to retain water within the cells, further supporting turgor pressure. When turgor pressure is lost, plants may wilt and lose their structural integrity.
The pressure vessel of a nuclear reactor contains the reactor core and helps to maintain a high pressure environment to prevent coolant water from boiling. It also serves as a barrier to contain radioactive materials and provide structural support for the reactor.
Electrons contain or maintain or have or are a negative charge. They do not contain anything physical that you can take out.
Coolant pressure begins to rise above 0psi as coolant temp increases. The pressure cap on the radiator or elsewhere will contain this rising pressure until it reaches the preset spec. written on the cap. Then a relief valve opens, and coolant is vented to the overflow or the ground to maintain pressure. Usually about 15psi.
Hibiscus leaves contain various pigments, primarily chlorophyll, which is responsible for their green color and plays a crucial role in photosynthesis. Additionally, they contain carotenoids, which can contribute yellow and orange hues, and anthocyanins, which may give some varieties a reddish tint. These pigments not only serve aesthetic purposes but also provide health benefits and protective functions for the plant.
