What else can I help you with?
What tissue type functions in the formation of membranes and glands?
dense fibrous connective tissue
Are cell membranes in prokaryotic and eukaryotic cells different in structure and function?
Yes, cell membranes in prokaryotic and eukaryotic cells have similar structures but differ in some aspects of their functions. Prokaryotic cell membranes lack membrane-bound organelles, while eukaryotic cell membranes contain them. Both types of cell membranes regulate the passage of substances in and out of the cell, but eukaryotic cell membranes are more complex due to the presence of organelles.
Why are organelles surrounded by membranes?
Organelles are surrounded by membranes to provide a barrier that controls what substances can enter and exit the organelles. This helps to maintain the organelle's internal environment, protect its contents, and facilitate specific functions within the cell. Additionally, the membranes of organelles contain specialized proteins that are essential for the organelle's structure and function.
Why are carbohydrates important in cell membranes?
Carbohydrates are important in cell membranes because they help with cell recognition and communication. They act as markers that allow cells to identify each other and interact properly. This is crucial for various cellular processes and functions within the body.
Do All membranes have exactly the same permeability characteristics?
No, all membranes do not have exactly the same permeability characteristics. Different membranes can have varying levels of permeability to different substances based on their structure and composition. Some membranes may be more selective in what substances they allow to pass through, while others may be more permeable.
What is a tissue membrane?
A tissue membrane is a thin layer of tissue that covers or surrounds structures in the body. These membranes serve various functions like protection, secretion, absorption, and support. Examples include the mucous membranes lining the digestive tract and the synovial membranes in the joints.
What are the functions that cell membranes perform?
Cell membranes perform several key functions, including acting as a barrier to regulate the passage of substances in and out of the cell, providing structural support to the cell, facilitating cell communication and signaling, and recognizing and binding to specific molecules like hormones or antigens.
Do mucous membranes contain enzymes?
Yes, things such as LYSOZOMES (antiseptic in saliva).
What lines the digestive and respiratory tract?
Mucous membranes line the digestive and respiratory tracts.
What characteristics of cell membranes may explain why fat-soluble substances such as chloroform and ether rapidly affect cells?
The fact that cell membranes are semi-permiable creates openings for the substances to enter.
What tissue type functions in the formation of membranes and glands?
dense fibrous connective tissue
What are membranes that allow only certain substances to pass through them?
Semi permeable membranes.
What do cell membranes do for the body?
Cell membranes act as a barrier, controlling the movement of substances in and out of the cell. They help maintain cell shape and provide support. Additionally, cell membranes are important for cell communication and recognition.

Yes, cell membranes in prokaryotic and eukaryotic cells have similar structures but differ in some aspects of their functions. Prokaryotic cell membranes lack membrane-bound organelles, while eukaryotic cell membranes contain them. Both types of cell membranes regulate the passage of substances in and out of the cell, but eukaryotic cell membranes are more complex due to the presence of organelles.
What are sores that affect the mucous membranes of the digestive system?
Peptic Ulcers
