Ribosomes are the smallest organelles isolated during cell fractionation. They are responsible for protein synthesis in the cell.
No, organelles are not made during growth phase 2 (G2) of the cell cycle. This phase is mainly focused on preparing the cell for division by synthesizing proteins and organelles are generally not synthesized during this time.
The cytoplasm divides during cytokinesis, and organelles are distributed to each new cell through a process called cytoplasmic segregation. This ensures that each daughter cell receives a complete set of organelles necessary for their function.
The egg cell supplies the mitochondria and other organelles to the zygote. Sperm cells do not contribute organelles to the zygote during fertilization.
