What of these transports nutrients made in the leaves to all parts of the plant?
Most of the useful nutrients are dissolved or suspended in groundwater. Capillary action draws this water into the roots and up the plant, as moisture transpires from the leaves of the plant, somewhat like a siphon. Capillary action is a consequence of the surface tension of water. Once the water is in the cells of the plant, its cellular processes extract nutrients in various ways.
Are there any cells in the body of a complex organism more than two cells away from a capillary?
No, in complex organisms all cells are located within a few cell diameters of a capillary to ensure efficient exchange of nutrients and waste products. This proximity allows for the delivery of oxygen and nutrients to cells and the removal of waste products through the circulatory system.
Which of the following would not move by diffusion across a capillary into the surrounding tissue?
Large proteins and cells like red blood cells would not move by diffusion across a capillary into the surrounding tissue. Diffusion is limited to small molecules and ions that can pass through the tiny gaps between endothelial cells.
What system responds by delivering more oxygen to the cells?
Circulatory system delivers blood (containing oxygen) to cells.
Why does water move inward in the root and upward in the stem?
Water moves inward in the root through a process called osmosis, where it travels from the soil into root cells that have a higher solute concentration. Once inside the plant, water moves upward through the stem via capillary action in the xylem vessels, aided by transpiration, which creates a negative pressure that pulls water upward from the roots to the leaves. This combination of osmotic movement and capillary action ensures efficient water transport throughout the plant.
How would you use capillary in a sentence?
The liquid was pulled into the small tube by capillary action.
What two kinds of cells use capillary action to raise water above the level of the ground?
The two types of cells that use capillary action to raise water above the ground level are xylem cells and root hair cells. Xylem cells transport water and nutrients from the roots to the rest of the plant, while root hair cells increase the surface area for water absorption from the soil. The combination of these cells enables plants to efficiently draw water upward through capillary action.
Through which plant cells does water move by capillary action?
Water moves through the xylem cells in plants by capillary action. Xylem cells are specialized to conduct water and minerals from the roots to the rest of the plant. The cohesion and adhesion properties of water molecules allow them to travel efficiently through the xylem tissue.
The respiratory membrane consists of what cells?
Alveolar squamous cells and Capillary endothelial cells.
Are the red blood cells in the capillary?
I Believe so
Why is it important that capillary cells have channels between them?
for difussion

Why is capillary action insufficient to move water through a plant?
Capillary action is not sufficient to move water through a plant because plants require a more specialized structure called xylem tissue to transport water from the roots to the rest of the plant. Xylem tissue is made up of specialized cells that are capable of conducting water through a process known as transpiration. This process is essential for providing the plant with adequate water for various metabolic functions.
Its pores prevent filtration of blood cells?
Capillary endothelium
Why is capillary blood glucose value higher than venous blood glucose?
Because the glucose in capillary blood is not fully delivered to the cells yet. Once the blood leaves the capillary and enters the vein, the glucose has then been delivered to the cells and the blood is considered used.
What is the function of capillary net?
to spread the blood cells so thin that the oxygen can be taken into cells or transferred to other cells.
