Each water molecule pulls on other water molecules as water is transpired from the leaves of the plant. This allows free movement of water throughout the plant.
What else can I help you with?
How are undigested nutrients in a vacuole made available to a cell?
Undigested nutrients in a vacuole are typically broken down further by enzymes within the vacuole to release smaller molecules. These smaller molecules can then be transported across the vacuole membrane into the cell's cytoplasm for utilization.
How do larger molecules move across epithelial membranes in the capillaries?
Larger molecules can cross epithelial membranes in capillaries through processes like transcytosis, where the molecule is taken up by the cell on one side and transported across the cell to be released on the other side. This process often involves vesicles that transport the molecule across the cell.
How do amino acids get to cells in every part of the body?
Amino acids are absorbed from the digestive system into the bloodstream and are transported to cells throughout the body. They are carried in the blood by proteins called albumin and specialized transporters. Once inside the cells, amino acids are used to build proteins and other essential molecules.
Proteins are transported from the nuclear membrane to other parts of the cell through the?
Newly synthesized proteins are transported from the nuclear membrane to other parts of the cell through the endoplasmic reticulum. The endoplasmic reticulum is a flattened and highly-folded organelle that lies near the nucleus in a eukaryotic cell.
What state does diffusion eventually lead to?
Diffusion leads to the state of equilibrium, where there is an equal distribution of molecules or particles throughout a system. At equilibrium, there is no net movement of particles from one area to another because the concentration gradient has been equalized.
What is the term used to describe the spread of molecules throughout the area?
Epitome spreading is the act of molecules self spreading. It can also be called mimicry. This is when molecules seem to mimic other molecules, but are replicating themselves.
What type of molecules are transported with osmosis?
Water molecules are primarily transported through osmosis, moving from an area of lower solute concentration to an area of higher solute concentration to balance the concentration levels. Osmosis does not involve the transportation of other types of molecules.
How are undigested nutrients in a vacuole made available to a cell?
Undigested nutrients in a vacuole are typically broken down further by enzymes within the vacuole to release smaller molecules. These smaller molecules can then be transported across the vacuole membrane into the cell's cytoplasm for utilization.
What does 60 GHz do to oxygen?
At 60 GHz, oxygen molecules can absorb electromagnetic radiation, which can affect the way they move and interact with other molecules. This can potentially impact the way oxygen is transported in the body and how it is used by cells.
How do mixture molecules interact with each other in a solution?
In a solution, mixture molecules interact by dispersing evenly throughout the solvent and forming temporary bonds with each other. This allows the molecules to mix together without separating, creating a homogeneous mixture.
How do you describe the motion of atoms in a solid?
Atoms move more freelythan they would in a soild or a liquid.
Where fat and water and other molecules are stored?
Fat is stored in adipose tissue throughout the body, water is stored in various body compartments such as blood, cells, and extracellular spaces, and other molecules are stored in cells throughout the body for various functions like energy production, structure, and signaling.
What substance is transported from the leafs to the roots?
In plants, sugars produced during photosynthesis in the leaves are transported to other parts of the plant, including the roots, through the phloem tissue. This process is known as translocation and is essential for distributing energy and nutrients throughout the plant.
What causes diffusion in the cell?
Diffusion is caused when molecules are moving around and bumping each other in the cell. Collisions cause the molecules to them push apart from one another. Eventually the molecules continue to do this and they spread throughout the area.
How is petroleum transported?
Petroleum and other oil products are transported by tankers. These can be trucks or ships. They can also be transported by pipeline.
Is likely to exit a cell via exocytosis?
Proteins or other molecules that need to be transported out of the cell are likely to exit via exocytosis. Exocytosis is a process in which vesicles fuse with the cell membrane to release their contents outside the cell. This is how cells release hormones, neurotransmitters, and other signaling molecules.
What Molecules produced in the nucleus are transported to the cytoplasm via?
Molecules produced in the nucleus, primarily messenger RNA (mRNA), are transported to the cytoplasm via nuclear pores. These pores facilitate the selective passage of mRNA and other macromolecules, such as ribosomal RNA (rRNA) and transfer RNA (tRNA), while maintaining the integrity of the nuclear environment. Once in the cytoplasm, mRNA is translated into proteins by ribosomes.
