Answer:
La célula es una estructura constituida por tres elementos básicos: membrana plasmática, citoplasma y material genético (ADN). Las células tienen la capacidad de realizar las tres funciones vitales: nutrición, relación y reproducción (ver t13). La forma de las células está determinada básicamente por su función.
Answer:
Solutes dissolved in water on either side of the cell membrane will tend to diffuse down their concentration gradients, but because most substances cannot pass freely through the lipid bilayer of the cell membrane, their movement is restricted to protein channels and specialized transport mechanisms in the membrane.
Explanation:
Answer:
The cells adapted by modifying their shapes.
Explanation:
The larger the cell, the smaller the surface / volume ratio. This can be a problem because it causes the cell to have difficulty in absorbing nutrients, in addition to having difficulties in releasing substances that are not relevant inside. To circumvent these difficulties and have a good functioning, many large cells adapt by modifying their shapes to increase their surface. In this way many large cells are presented with a thin and elongated shape, others create several appendages on their surface.
