in cell duplication the DNA (deoxyribonucleicacid) of a cell is litterlly duplicated and the membrane is sort of like skin, it helps to keep the bad stuff out and the good stuff in. no cell wall no cell; because if humans didn't have cell walls we would all be a puddle of liquid mush.
What else can I help you with?
How does the plasma membrane maintain homeostasis?
The Plasma membrane maintains the homeostasis throughout a cell because it filters what substances go in and out of the cell. If there is too much of a substance in a cell the plasma membrane quickly disposes it and when there is not enough of a substance in a cell the plasma membrane lets the substance in.The plasma membrane uses selective permeability to maintain homeostasis in a cell by eliminating wastes and taking in needed items.
Is homeostasis the quality of a plasma membrane that allows oxygen and glucose to move in?
Homeostasis refers to the maintenance of a stable internal environment in an organism. The permeability of the plasma membrane allows for the selective movement of substances like oxygen and glucose into cells to help maintain homeostasis by regulating internal conditions.
WHAT IS THE cell most responsible for maintaining homeostasis in all cell?
The cell most responsible for maintaining homeostasis in the body is the epithelial cell. Epithelial cells form tight barriers between different compartments of the body, regulate the movement of substances in and out of cells, and help maintain the balance of ions and nutrients. Their functions contribute to overall cellular homeostasis.
What type of membrane is membrane plasma?
The plasma membrane is a phospholipid bilayer membrane that surrounds the cell, serving as a protective barrier. It is selectively permeable, allowing certain molecules to enter and exit the cell. The plasma membrane also contains proteins that help with cell communication and transport.
What is plasma membrane role in metabolism?
The plasma membrane helps to control the movement of substances into and out of cells, allowing for the regulation of metabolic processes. It also contains various transport proteins and receptors that are essential for nutrient uptake and signal transduction, both of which are key aspects of metabolism. Overall, the plasma membrane plays a crucial role in maintaining cellular homeostasis and ensuring that metabolic reactions can occur efficiently.
What function does the proteins that are attached to the inside and outside of the plasma membrane have?
Proteins attached to the inside and outside of the plasma membrane play crucial roles in various cellular functions. They assist in cell signaling by acting as receptors that bind to specific molecules, facilitating communication between the cell and its environment. Additionally, these proteins contribute to the structural integrity of the cell, help transport substances across the membrane, and are involved in cell recognition and adhesion processes. Overall, they are essential for maintaining cellular homeostasis and responding to external stimuli.
What help control what enters and leaves a cell?
The plasma membrane
What is the function of the carbohydrates that stick out if the plasma membrane?
The carbohydrates help identify chemical signals and define the characteristics of the cell.
What is the structure and function of the plasma membrane?
The plasma membrane is a phospholipid bilayer that surrounds cells, acting as a barrier between the internal and external environment. It regulates the passage of substances in and out of the cell, maintaining cellular homeostasis and providing structural support to the cell. Additionally, the plasma membrane contains proteins that help with cell signaling, adhesion, and transport.
How is the plasma membrane related to the lysosome?
The plasma membrane surrounds the cell and regulates the movement of substances in and out of the cell. Lysosomes are membrane-bound organelles that contain digestive enzymes to break down waste materials. Lysosomes fuse with the plasma membrane to release their enzymes outside the cell for extracellular digestion.
The plasma membrane has a double layer of phospholipids with what dispersed throughout?
Proteins are dispersed throughout the plasma membrane along with cholesterol molecules. These components help maintain the structure and functions of the membrane.
What is the main fuction of the plasma membrane?
The main function of plasma membrane is to regulate things in or out of the cell cytoplasm by osmosis,active diffusion,passive diffusion,endocytosis,ectocytosis etc because it acts as selectively permeable membrane.Plasma membrane forms a barrier between the interstitial fluid and inside cell environment. It is selectively permeable. Plasma membrane has trans membrane proteins embedded in it.
