A secretory cell modifies, sorts and packages newly made proteins into vesicles before release. Which organelle performs that job?

A cell needs to make many enzymes for export outside the plasma membrane. Which organelle assembles the protein chains?

Which organelle releases energy from food molecules and captures much of it as ATP for cell work?

A cell must digest worn-out organelles and recycle their building blocks. Which organelle carries out that breakdown?

Which organelle stores the cell's DNA and controls gene expression for the cell?

A steroid-producing gland cell needs extra membrane surface for lipid synthesis. Which organelle is most directly used?

Which organelle helps detoxify hydrogen peroxide by using oxidative enzymes such as catalase?

A cell must keep its internal fluid separate from the tissue fluid outside it while controlling entry and exit. Which structure does this?

A cell is building the small subunits that will later join mRNA in the cytoplasm. Which nuclear structure makes those subunits?

A white blood cell engulfs bacteria into a vesicle and must destroy them. Which organelle fuses with that vesicle?

Which organelle moves proteins into a membrane network as they are made, beginning their folding and processing?

A cell needs a track system for moving vesicles and for maintaining its shape. Which structure provides that framework?

During cell division, which structure organizes microtubules that help separate chromosomes?

Which small membrane-bound sac transports material from one organelle to another or to the plasma membrane?

What is the main job of ribosomes in a human cell?

What does the Golgi apparatus do to many proteins it receives?

What is the main function of the nucleus?

What does smooth endoplasmic reticulum commonly do in cells?

What do lysosomes do for the cell?

What is the main role of mitochondria in cell physiology?

What does the plasma membrane do?

What is the job of the nucleolus?

What is one major function of peroxisomes?

What does the cytoskeleton help a cell do?

An organelle has two membranes, inner folds and its own small DNA loop. Which organelle is it?

A stack of flattened membrane sacs sits near the endoplasmic reticulum and buds off transport sacs. Which organelle matches this structure?

Tiny nonmembranous particles made of RNA and protein can be free in cytoplasm or attached to a membrane network. What are they?

An organelle is a large compartment enclosed by a double membrane with pores and contains chromatin. Which organelle is it?

A membrane system is studded with many ribosomes on its outer surface. Which organelle is being described?

A membrane network has no ribosomes attached and is abundant in cells that make lipids. Which organelle is it?

A small sac contains digestive enzymes in an acidic interior. Which organelle matches that description?

A dense body inside the nucleus has no surrounding membrane and is where ribosomal subunits begin assembly. What is it?

If rough endoplasmic reticulum stopped working, which cell process would be most directly impaired?

If a cell's mitochondria failed, what would happen first to its energy supply?

If lysosomal enzymes were not released into food vacuoles, what would accumulate inside the cell?

If the Golgi apparatus could not form vesicles, which outcome would most directly follow?

If ribosomes stopped functioning, which cell activity would fail most directly?

If the plasma membrane lost selective permeability, what would the cell lose most directly?

If the nucleolus stopped working, which product would the cell make too slowly?

If peroxisomes could no longer use catalase, which toxic molecule would be harder for the cell to break down?
