Plasma membrane - protect cell from it's surroundings. In both kinds of cells.


Cytoplasm - supports rounded cell structure, within it are all the organelles. Contains chemicals needed by the cell. In both kinds of cells.


Nucleus - contains DNA and is the control center of the cell. In both kinds of cells.


Nuclear envelope - surrounds nucleus, makes sure important molecules (DNA) stay within the nucleus. In both cells.


Nucleolus - makes ribosomes. In both cells.


DNA - genetic information for development and function. In both cells.


Rough ER - produces proteins. In both cells.


Smooth ER - makes and stores lipids (fats). In both cells.


Golgi body - sort and process macromolecules (proteins, lipids, etc). In both cells.


Ribosomes - makes proteins. In both cells.


Vacuoles - very large in plants, a storage center. In both cells.


Lysosome - digests and removes wastes. In both cells.


Mitochondria - energy powerhouse, produce ATP energy. In both cells.


Cytoskeleton - shapes, supports, and facilitates movement. In both cells.


Centrioles - cell division (form spindle fibers). Only in animal cells.


Cilia - movement for microorganisms. Only in animal cells.


Chloroplasts - photosynthesis, helps absorb sunlight and make food for the plant. Only in plant cells.


Cell wall - strength, structure, filters molecules going in and out of the cell. Only in plant cells.


Central Vacuole - holds materials and wastes, helps maintain proper pressure within the cell. Only in plant cells.


Hope this helps!

tatuchka [14]

During T cell maturation, the t cells must pass two tests. first, immature t cells that can recognize MHC molecules are Selection. Second, immature t cells that recognize and bind to molecules normally found in the body are Activation.

Selection is the first test that T cells must pass. During this process, immature T cells that can recognize MHC molecules are selected. MHC molecules are found on the surface of cells and are involved in antigen presentation. When T cells come into contact with MHC molecules, they are able to recognize the molecules and begin the process of selection. During selection, the T cells that recognize MHC molecules are chosen over those that do not. This helps ensure that the cells that are selected are those that can properly respond to antigens.

The second test that T cells must pass is activation. During activation, T cells that recognize and bind to molecules normally found in the body are selected. These molecules are called self-antigens and can include proteins, carbohydrates, and lipids. When T cells come into contact with self-antigens, they are able to recognize the molecules and begin the process of activation. During activation, the T cells that recognize self-antigens are chosen over those that do not. This helps ensure that the cells that are selected are those that will not attack the body’s own cells.
