Chromatin is responsible for gene expression because chromatin contains DNA that has all information about genes. chromatin controls the gene in order to form encoded products. DNA in chromatin send information to the RNA to produce specific types of proteins that are needed by the organisms for its growth and development so in that way the genes can be expressed in the organism.
Explanation: Mitochondria create energy for both plant cells and animal cells through cellular respiration. Chloroplasts create energy for plant cells through photosynthesis.
