How the components of a cell's membrane provide its functions?
The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.
What are two main functions of the cell membrane?
Narration. The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.

What is composite cell?
Follow Us: A composite cell is any one of a collection of different types of cells that all have the same general chemical makeup that perform the same functions. Because many cells are very similar to one another in these ways, it is possible to generalize them all as composite cells.
Why are cells considered composite cells?
Because many cells are very similar to one another in these ways, it is possible to generalize them all as composite cells. Cell theory states that many cells are chemically similar to one another and have the same basic elemental composition: carbon, hydrogen, nitrogen, oxygen and trace amounts of other elements.
Do composite cells have the same functions?
In all composite cells, these structures have similar shapes and perform the same functions, regardless of where in the body the cell is found.

Structure Of A Generalized Cell. Though cells may differ in shape and size, all of them have the same basic structure, referred to as the generalized cell structure or generalized cell. A cell has both living and non-living parts.
What are the parts of a cell that have a definite shape, structure, and function?
The living parts of the cell that have a definite shape, structure, and function are called organelles. The main parts of a generalized cell are cell membrane, cytoplasm, and nucleus. Cell membrane: It is the outer covering of a cell. It is a porous membrane through which selected substances can enter or leave the cell.
What are the chemical substances that are capable of digesting cells and a variety of intra- and extra-cellular materials
Lysosome: Lysosomes contain chemical substances called enzymes that are capable of digesting cells and a variety of intra- and extra-cellular materials [intra, internal (inside); extra, external (outside)]. In times of emergency, lysosomes burst and destroy the cell. Hence, they are also called suicide bags of the cell.

Let’s begin our study of the cell by investigating the basic anatomy of an animal cell. Each cell consists of three components shown in the image above.
What are the basic concepts of cell theory?
The current cell theory states that: 1 All known living things are composed of one or more cells. 2 All new cells are created by pre-existing cells dividing in two. 3 The cell is the most basic unit of structure and function in all living organisms.
Which organelle generates ATP?
It is very important that the enzymes remain in the lysosome or they would destroy the cell. The power plant of the cell is the mitochondria. This organelle generates the ATP or energy for the cell. Mitochondria even have their own DNA termed mitochondrial DNA (mDNA) and can replicate.
What is the garbage man of the cell?
The golgi apparatus also makes a special type of vesicle termed a lysosome. The lysosome is the garbage man of the cell. It takes in cell debris and waste and destroys it.
What organelle makes proteins?
Other organelles help synthesize the proteins needed by the cell. These protein factories are called ribosomes. They can be scattered within the cell or attached to a membrane channel system called the endoplasmic reticulum or ER. When the ER has ribosomes attached to it, it is termed the rough ER (the ribosomes give it a rough or grainy appearance). When the ER lacks ribosomes it is termed the smooth ER and functions for lipid synthesis and storage of toxins. When a protein is manufactured it must be folded into a specific shape to work. Often additional side chains of carbohydrates must be attached. The protein is processed in the rough ER. Once it is formed it enters the golgi apparatus which is the distributing plant for the cell. It completes any protein processing and then packages it into a vesicle for transport to its destination. Some proteins are needed in the cell membrane and the vesicles make sure they reach the membrane. The golgi apparatus also makes a special type of vesicle termed a lysosome. The lysosome is the garbage man of the cell. It takes in cell debris and waste and destroys it. The lysosome contains very powerful hydrolytic enzymes to accomplish this. It is very important that the enzymes remain in the lysosome or they would destroy the cell.
What are the proteins that move the cells around the cell?
These protein rich organelles include intermediate filaments, microtubules, and microfilaments. Some of these actually move other organelles around the cell or change the shape of the cell. When a muscle cell contracts or shortens it does so by the microfilaments made up of the proteins actin and myosin.
What are the organelles of a cell?
There are organelles whose job is to provide shape and structure to the cell, much like the city streets and bridges. These protein rich organelles include intermediate filaments, microtubules, and microfilaments. Some of these actually move other organelles around the cell or change the shape of the cell. When a muscle cell contracts or shortens it does so by the microfilaments made up of the proteins actin and myosin. One special organelle composed of microtubules is located in an area near the nucleus, the centrosome. The centrosome contains a pair called of microtubule bundles known as the centrioles. Centrioles are important because they move chromosomes to opposite ends of the cell during cell replication termed mitosis. Neurons do not have centrioles and cannot replicate.
What is fully coupled HFGMC?
The fully coupled HFGMC micromechanical model is now established to predict the fully coupled thermo-inelastic behavior of triply periodic composites. The local (subcell) constitutive equation of the material, which in general is assumed to be thermo-inelastic, is given (cf. Eq. (8.34)) in matrix notation by
