4. membranous sac that stores or transports substances
5. dense body of rna and protein within the nucleus
6. slender tubes that provide movement in cilia and flagella
7. composed of membrane - bound canals and sacs for tubular transport throughout the cytoplasm
8. occupies space between cell membrane and nucleus
9. flattened, membranous sacs that package a secretion
10. membranous sac that contains digestive enzymes
11. separates nuclear contents from cytoplasm
12. spherical organelle that contains chromatin and nucleolus

Explanation:

Chromatin is the loosely - coiled fibers containing protein and DNA within the nucleus. Cytoplasm occupies the space between the cell membrane and nucleus. Endoplasmic reticulum is composed of membrane - bound canals and sacs for tubular transport throughout the cytoplasm. Golgi apparatus are flattened, membranous sacs that package a secretion. Lysosome is a membranous sac that contains digestive enzymes. Microtubule are slender tubes that provide movement in cilia and flagella. Mitochondrion is the location of ATP production for cellular energy. Nuclear envelope separates nuclear contents from cytoplasm. Nucleolus is a dense body of RNA and protein within the nucleus. Nucleus is a spherical organelle that contains chromatin and nucleolus. Ribosome are small RNA - containing particles for the synthesis of proteins. Vesicle is a membranous sac that stores or transports substances.
