Explanation:
This statement is true.
Reason:
Plants are capable of storing energy from the sun and with the help of that they produce their own food. And this energy is transformed to the animals as well as human being when they consume the food which was grown on the plants. But when they consume it they are only able to get 10% of the energy and the last consumers are able to get only about 1% of the energy.
Answer:
B
Explanation:
Arteries and arterioles (small arteries) have muscular walls. They're the main blood vessels involved in vasoconstriction. ... Capillaries are tiny, thin-walled blood vessels that can't constrict.
In order for plants to produce energy and maintain cellular function, their cells undergo the highly intricate process of photosynthesis. Critical in this process is the stoma. Stomata (multiple stoma) are located on the outermost cellular layer of leaves, stems, and other plant parts. An open stoma facilitates the process of photosynthesis in three ways. First, it allows light to enter the intercellular matter and trigger the process. Second, it allows for the uptake of carbon dioxide, a key chemical in producing plant energy. Third, it allows for oxygen to be expelled into the outside environment, a byproduct of photosynthesis that is no longer needed by the cell.
