All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. ... Ribosomes are the non-membrane bound organelles where proteins are made, a process called protein synthesis. The cytoplasm isall the contents of the cell inside the cell membrane, not including the nucleus. Where is the c...
Plant cells have cell walls around them, but it is not so in the animal cell. It givesplant cells their boxy shapes and ability to grow up and outso that they get lots of sunlight for making their food. Plants need a rigid structure. ... The cell wall is tough and flexible but som...
The genome is the collection of all the DNA inside the cell. The genome is important because it controls all cell structure and function through the regulation of gene expression. Answer and Explanation:1 All human cells do not have the same genome. Although human cells start with the same ...
