How do cells respond to their environment? (i need a short example)

do cells use energy? (short example)

~aurora

Cells contain many receptors integrated into their membranes. They also communicate to other cells through secretion of signalling molecules. 

It is very important for cells to be able to communicate with each other to maintain a single cohesive organism. If our cells didn't work together and communicate we would be a mass of cells rather than an organism of cells working together to serve a common purpose.

hope this helped :) if you have any other questions I'd be happy to answer them for you   

The main role of dna in the  cell is the long-term storage of information. it is often compared to a blueprint, since it contains the instructions to construct other components of the  cell, such as  proteins  and rna molecules.the main function of rna is to carry information of amino acid sequence from the genes to where  proteins  are assembled on  ribosomes  in the  cytoplasm. mark brainliest, my work is good.
