Adjacent plant cells have narrow channels called plasmodesmata that pass through the cell walls of the connected cells and allow

a cytoplasmic connection between the cells.
Which of the following statements best describes a primary function of plasmodesmata?

1. They allow the movement of molecules from one cell to another, enabling communication between cells.
2. They prevent the cell membrane from pulling away from the cell wall during periods of drought.
3. They eliminate the need to produce signaling molecules and eliminate the need for cells to have receptors for signaling molecules.
4. They increase the surface area available for attachment of ribosomes and thus increase protein synthesis.

Answer:

A

Explanation:

Plant cells are encompassed in cell walls that form the plant skeletal structure. However, the presence of abundant extracellular cell wall material means that plant cells physically do not touch. To enable intercellular communication, plants have evolved cytoplasmic bridges, called plasmodesmata (Sing- Plasmodesma) that links the fluid cytoplasm between adjacent cells. The plasma membrane of one plant cell is continuous with that of its neighbour at each plasmodesma.

A Plasmodesma (Plural- Plasmodesmata) is a narrow channel through the plant cell wall that acts as intercellular cytoplasmic bridges to bring about communication and transport of materials between plant cells. Plasmodesmata form an important route for communication between plant cells, allowing molecules to pass directly from cell to cell.

The plasmodesmata separate the outer cell membranes of the plant cells. The actual air space separating the cells is called the desmotubule.

Answer:1. They allow the movement of molecules from one cell to another, enabling communication between cells.

Explanation:the cell wall is a rigid and cellulose containing wall, which surrounds the plasma membrane.

During lignification, small pores appear on the cell wall through which cytoplasmic strands extend.these pores are the plasmodesmata,which provides connections between plant cells

If the producer contains 6000 of energy how much energy will the secondary consumer contain
AVprozaik [17]
The proportion of energy transferred from one trophic level to the next is known as trophic level transfer efficiency or ecological efficiency. The Ten Percent law states that 'net production at one trophic level is generally only 10% of the net production at the preceding trophic level'. In this example, the producer contains 6000 units of energy. 10% of this will be transferred to the primary consumer, i.e. 600 units. In turn, 10% of this energy will be transferred to the secondary consumer i.e. 60 units.

Viscous fiber helps to lower blood cholesterol levels by interfering with the reabsorption of ________ in the intestines.
Yuki888 [10]
By interfering with the absorption of BILE in the intestine. Bile contains cholesterol, if it absorbed from the intestines it will increase the level of cholesterol in the blood stream. So, the viscous fiber stop this by sequestering the bile acids.

I’ll mark brainliest <br> how do organisms with many cell types develop from a single cell
Rashid [163]

Answer:

A multicellular organism develops from a single cell (the zygote) into a collection of many different cell types, organized into tissues and organs.During development, cells use both intrinsic, or inherited, information and extrinsic signals from neighbors to "decide on" their behavior and identity.

Question 1 Life would cease to exist without energy from the sun or some other source.
malfutka [58]

Answer:

Q1) True

Q2) Metabolism

Q3) Physiological response

Explanation:

Q1) Energy cannot be created (first law of thermodynamics). Life needs an energy source to transform. Without the energy from the sun or any other sources, life would cease to exist. (True)

Q2) An organism chemical reactions consist, in general, breaking down complex molecules (catabolism) releasing energy or to form complex structures from simpler molecules (anabolism) which require energy . The total of this reactions is called metabolism.

Q3) Hibernation is physiological state of inactivity and metabolic depression in some organisms, which result as a response to low temperatures and unavailability of food.
