Water pressure in stems and leaves helps to

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.
Hope this helps!

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.

PolarNik [594]

Answer:

Sponges use choanocytes or flagellated channels to get nutrients from the feeding cells to other parts of their body.

Explanation:

Sponges are marine animals with a sac-shaped body. The epidermis is composed of polygonal flat cells called pinacocytes and pores protected by porocytes. Under the epidermis, there is a protein matrix called mesenchyme, which is composed of spicules and amibocytes. By the interior side of the sponge, there are the choanocytes. These are ovoid cells that can be shaping the spongocoele (internal cavity of the sponge), with an extreme attached to the mesenchyme and the other extreme projected to the spongocoele, or can be grouped in spaces called flagellated channels.

These animals depend on water to get oxygen and food to the inside of the sac and take excrements and reproductive cells to the outside. Sponges feed on small detritus particles and suspending organisms that get near the animal by water streams produced by choanocytes.

Particle size is essential. Only the small ones can get through the flagellated channels, where they get stuck to the choanocytes and are encapsulated by the cells. If the choanocytes are too small, the particle is transferred to the amibocytes for digestion. These last ones also act as food storages. Excrement products are dragged by a water stream.

Answer:

Melody is a rhythmic sequence of pitches that create a musical phrase or motif. A melody also consists of two parts: pitch and rhythm. We sometimes think of melodies as the vocal part of a song. However, a melody can also be the top line of your instrumental drop, a signature bass line, or even a unique vocal sample.
