Question

1. a network of channels called the ________ is used for moving materials within the cell. proteins endoplasmic reticulum cell wall size life processes cell membrane chlorophyll nucleus energy cells chloroplasts shape your answer

Explanation:

To solve this, we recall cell organelle functions. The endoplasmic reticulum (ER) is a network of channels (tubules and sacs) that helps in transporting materials (like proteins, lipids) within the cell. Proteins are molecules, cell wall provides structure/support, size is a cell characteristic, life processes are cell activities, cell membrane controls entry/exit, chlorophyll is in chloroplasts for photosynthesis, nucleus is the control center, energy is related to mitochondria, cells are the basic unit, chloroplasts do photosynthesis, shape is related to cell structure. So the correct term is endoplasmic reticulum.

Answer:

endoplasmic reticulum
