Cell membranes usually allow what substances to enter a cell?
the cell membrane allows what substance to enter the cells.
What is permeable tissue?
the definition of the of tissue permeability is: - The absorption of substances within the body tissues. cell permeability, which allows nutrients and other substances to enter the cells more readily and allows the removal of waste products from the cells.
Viruses enter animal cells by?
Viruses attach to the cell membrane of animal cells and break it, injecting their genetic material (RNA, sometimes DNA) into the cell. This DNA integrates itself into the host DNA and replicates with it, hijacking the cellular components.
What animal has a nucleus?
Most animal cells (except for human red blood cells and some others) have a nucleus. It is like a control centre in the cell which allows some substances to enter and others substances to leave the cell. It also initiates chemical reactions and processes like respiration in the cell cytoplasm.
What must the molecules in a capillary enter before they enter the cell?
Molecules traveling within the bloodstream pass through the capillary cell wall via osmotic pressure and diffuse through the interstitial fluid before encountering the tissue cell wall.
What kind of blood vessels allow substances to enter and leave the blood so easily around the cells?
Capillaries, which are only one cell thick. The walls are semipermeable to the cell membranes in the body and are so narrow that red blood cells must pass through in a line, one behind the other. Oxygen and nutrients diffuse from the capillary to the body cells at the arterial end of the capillary while CO2 and other metabolic wastes enter the capillary at the venous end, because of diffusion gradients between the cell and the plasma and cells in the capillary.
Why water and dissolved substances leave the arterioles end of the capillary and enter the venule end?
Water and dissolved substances leave the arteriole end of the capillary due to hydrostatic pressure being higher than osmotic pressure and enter the venule of the capillary due to osmotic pressure being higher than hydrostatic pressure.
Detoxify harmful substances that enter cells?
Perioxisomes
Which term refers to the movement of white blood cells between endothelial cells lining capillary walls to enter the tissue?
Diapedesis
What is different about the capillary exchanges seen in a capillary with fenestrations and intercellular clefts and the exchanges seen in a capillary lacking those modifications?
Capillaries with fenestrations and intercellular clefts allow for different diffusion of substances depending on structural characteristics (and permeability) of the capillary. Fenestrated capillaries are found where absorption are a priority, such as the intestines or endocrine glands, or where filtration occurs, such as the kidneys. A fenestra is an oval pore covered (usually) by a delicate membrane, and is much more permeable than a plain plasma membrane. Intercellular clefts are gaps in the plasma membrane, or areas not joined tightly, and are another way substances can enter the cell. Almost all capillaries have these. Substances can diffuse directly through the plasma membranes of cells only if the substances are lipid-soluble (like the respiratory gases), and certain lipid-insoluble substances can enter or leave the blood by passing through the plasma membranes of endothelial cells within vesicles, by endo or exocytosis.
What is the process by which substances enter and leave cells and become distributed within cells?
Transport
What cells attack germs or substances that enter your body and cause infections?
Your white blood cells have that job.
White blood cells that may leave the cardiovascular system and enter the fluid surrounding the body's cells?
Macrophages
Cell membranes usually allow what substances to enter a cell?
the cell membrane allows what substance to enter the cells.
How do substances for photosynthesis enter the plant?
Pores called stomata, which open and close by guard cells.
Cells are limited in size by the?
a. rate at which substances needed by the cell can enter the cell through its surface.
What substances enter and leave the cells?
Proteins made on "bound" (attached) ribosomes leave through the cell membrane, and other proteins will enter the cell.
