nucleolus. it is not a little nucleus, but instead it is part of the nucleus.
Lysosome
Jelly like cells inside the body are called cytoplasm. This is part of the cell membrane.
The goo inside cells is called cytoplasm. It is a jelly-like substance that fills the cell and surrounds the organelles. It contains various molecules, proteins, and nutrients necessary for cell function.
Organelles.
