Question

match the organelle to its function. membrane - bound sacs that store and transport substances within cells synthesizes ribosomes (rrna) contains digestive enzymes to break down cellular waste, old organelles, bacteria/viruses; plays a role in apoptosis modifies, sorts, and packages proteins and lipids from the endoplasmic reticulum (er) into vesicles for delivery to specific destinations within or outside the cell selectively permeable to regulate what can enter/exit the cell hair - like appendages on cells that propel fluids and debris; can act like a sensory organ synthesizing proteins for intracellular use

Explanation:

1. Membrane - bound sacs that store and transport substances: Vesicles. They are small membrane - enclosed structures that carry materials within the cell or to the cell membrane for secretion or uptake.
2. Synthesizes ribosomes (rRNA): Nucleolus. It is a sub - structure within the nucleus where ribosomal RNA is synthesized and ribosome assembly begins.
3. Contains digestive enzymes to break down cellular waste, old organelles, bacteria/viruses; plays a role in apoptosis: Lysosome. Lysosomes are organelles with hydrolytic enzymes that degrade various substances and are involved in programmed cell death (apoptosis).
4. Modifies, sorts, and packages proteins and lipids from the endoplasmic reticulum (ER) into vesicles for delivery to specific destinations within or outside the cell: Golgi apparatus. It is a stack of flattened membranes that processes and packages macromolecules.
5. Endoplasmic reticulum (ER): There are two types, rough ER (with ribosomes attached, involved in protein synthesis) and smooth ER (involved in lipid synthesis, detoxification etc.).
6. Selectively permeable to regulate what can enter/exit the cell: Cell membrane. It controls the movement of substances in and out of the cell through various transport mechanisms.
7. Hair - like appendages on cells that propel fluids and debris; can act like a sensory organ: Cilia. Cilia are short, hair - like structures on the cell surface that can move in coordinated waves to move substances along the cell surface or act as sensory receptors.

Answer:

1. Vesicles
2. Nucleolus
3. Lysosome
4. Golgi apparatus
5. Endoplasmic reticulum
