Water pressure in stems and leaves helps to

Biology

Over [174]3 years ago

When there is water in the cell of a stem or leaves, the cytoplasm swells up and creates a pressure against its cell walls. That cell pushes against its surrounding cells. Those surrounding cells exert a pressure in the cells surrounding them and so on. This pressure is known as turgid pressure, and it keeps the non-woody parts of the plant, such as the leaves and the stem, upright and rigid.
When a cell loses enough water to become flaccid, the cytoplasm starts to peel away from the cell wall. Its cytoplasm no longer exerts a pressure on its cell wall. Therefore the cell no longer exerts a pressure on its surrounding cells, who don’t exert a pressure on the cells surrounding them. This lack of pressure causes the plant to wilt.

Answer:

When the soil of a plant runs too low of available water, the water chains in the xylem become thinner and thinner due to less water. Effectively, the plant is losing water faster than it is absorbing it. When this happens, the plant loses its turgidity and begins to wilt.

Answer:

B)  The mass of the reactants equals the mass of the products,

Explanation:

Given that the reaction is balanced, the mass of the reactants must equal to the mass of the products.

We know this by virtue of the law of conservation of mass.

 The law of conservation of mass states that "in a chemical reaction, matter is neither created nor destroyed but atoms are rearranged".

 Therefore, if the reaction is chemically balanced, the mass of reactants must be the same as the mass of the products in the reaction.

The second choice is the right one.

alexira [117]

Answer:

gross anatomy, an anatomical region

Explanation:

Anatomy can be grouped into gross anatomy and superficial anatomy. Gross anatomy is the study of structures that are visible to the human eye i.e. without the aid of a microscope. The anatomical regions are those regions in the body that are easily seen by the unaided eye.

In this case, Luna is trying to study the name and locations of the lumbar, or lower back, area of the body. The lumbar is the vertebrae found at the lower back of the body. Hence, it is an easily visible internal structure when dissected, making it's study a form of GROSS ANATOMY.
