NettetG1 Phase. During this phase, cells do most of their growing and make new proteins and organelles. S Phase. During this phase, DNA (chromosomes) is replicated. G2 Phase. During this phase, the cell prepares for cell division by preparing the organelles needed for division. -Cell also grows a little more. Nettet1. A zygote generally has a lot of nutrients, essential biomolecules like RNA and proteins and cytoplasmic organelles for rapid division. So the cell does not grow and divide but rather undergoes "cleavage" (there is no G1 phase of cell cycle). However, it still undergoes DNA replication.
