One hemisphere is labeled with the parts of the cell- the other features only letters next to each cell part for assessment. As with animal cells, the diagram of the plant cell above is a generalised diagram to show the structures. Log in required. Explore the cell diagrams in the following images below. Ribosomes are very small organelles (non-membranous) and are present in thousands (millions in some) inside the cell. Changes in the number or structure of chromosomes in new cells can result in serious problems. Ribosomes are small, spherical organelles comprising 65% ribosomal RNA and 35% ribosomal proteins. Vacuoles are present in most animal cells, however, are smaller, as compared to the plant cell vacuole. This process is known as cellular respiration, and the ATP or energy produced is used to carry out functions like locomotion, cell division, production of secretory products, etc. From amoebae to earthworms to mushrooms, grass, bugs, and you.
