Can someone please tell me what part of a cell are sacs that contain digestive material? Also, what part of a cell is a network of canals?

The part of a cell that contains sacs with digestive material is called the "lysosomes." Lysosomes are membrane-bound organelles that contain various enzymes capable of breaking down various molecules, such as proteins, nucleic acids, lipids, and carbohydrates.

Now, moving on to the second part of your question, the network of canals in a cell is referred to as the "endoplasmic reticulum" (ER). The endoplasmic reticulum is involved in the synthesis, folding, and transport of proteins and lipids throughout the cell. It consists of two regions: the rough endoplasmic reticulum (RER), which contains ribosomes on its surface, giving it a rough appearance, and the smooth endoplasmic reticulum (SER), which lacks ribosomes and participates in processes such as lipid metabolism and detoxification.

If you ever come across similar questions in the future, you can always refer to reliable sources like biology textbooks, online educational websites, or even scientific journals. These sources provide detailed information about various cellular components and functions. Additionally, specific search engines tailored for academic research, such as Google Scholar or PubMed, can also provide relevant scientific articles related to the topic at hand.
