What else can I help you with?
The part of the cell that is in most direct contact with the environment is the?
The cell membrane, which surrounds the cell and is responsible for which molecules are allowed to diffuse into or out of the cell and which molecules are impermeable to the membrane
Where is psuedostratified epithelium located?
Psuedostratified epithelial tissue is epithelial tissue that looks as though it is multiple layers, i.e. stratified, but actually each cell is anchored to the basement membrane. It can be found chiefly lining the respiratory tract.
What is membrane gelling?
Membrane gelling refers to the process where a liquid or sol forms a gel-like structure when it comes into contact with a membrane. This can be used in various applications such as filtration, separation processes, and drug delivery systems. The membrane provides a supportive matrix for the gel formation.
Where does a cell membrane come in contact with water?
Cell membranes come into contact with water throughout the human body. The cell membrane comes into the most contact with water in the bladder, which holds urine that is mainly composed of water.
What kind of tissue forms a protective surface on the outside of your body?
The tissue on the outermost part of your body is the skin, which is made up of epithelial tissue. The layer that comes into contact with the atmosphere is called the epidermis.
Skin cancer that causes epithelial cells to not be in contact with basement membrane?
Squamous cell carcinoma
Can the epithelial tissues be called semipermeable membrane?
Yes, a semipermeable membrane selectively allows chemicals to be absorbed into the body. Epithelial tissue covers all parts of the body that has contact to the the outside environment including the gastric tract. One prime example of semipermeable epithelial tissue of the body is the tissue of the intestines which has folds exactly for the purpose of absorbing food.
In transitional epithelial do all cells touch the basement membrane?
No, not all cells in transitional epithelium touch the basement membrane. This type of epithelium is designed to stretch and change shape, so the cells may not always be in direct contact with the basement membrane.
What is the layer of epithelial cells in contact with blood in the heart?
endocardium
What tissues have cells that are in direct contact with the external environment?
Epithelial tissues.
What structure in a plant cell may force the cell membrane into contact with the cell wall?
The structure in a plant cell that may force the cell membrane into contact with the cell wall is the plasma membrane. This will also come into contact with the vesicle membrane.
The ossicle of the ear that is in contact with the tympanic membrane is the?
incus
The part of the cell that is in most direct contact with the environment is the?
The cell membrane, which surrounds the cell and is responsible for which molecules are allowed to diffuse into or out of the cell and which molecules are impermeable to the membrane
What is the part of the cell that is in most direct contact with the enviorment?
The cell membrane.
What is a description of Pseudostratified ciliated epithelium?
Pseudostratified ciliated epithelium is a type of epithelial tissue found in the respiratory tract. It appears to be stratified due to the nuclei being at different levels, but all cells are in contact with the basement membrane. Most of the cells have cilia on their apical surface, which help in moving debris and mucus out of the respiratory system.
Where is psuedostratified epithelium located?
Psuedostratified epithelial tissue is epithelial tissue that looks as though it is multiple layers, i.e. stratified, but actually each cell is anchored to the basement membrane. It can be found chiefly lining the respiratory tract.
Does contact of a sperm with the oocyte membrane cause a completion of the second meosis?
Yes, contact of a sperm with the oocyte membrane triggers the completion of the second meiosis in the oocyte, leading to the formation of the female pronucleus. This process is essential for fertilization to occur.
