TABLE 1- MATCHING: WRITE THE CORRECT CELL STRUCTURE NEXT TO EACH PHRASE. Cell structures to choose from: cell membrane, cell wall, chloroplast, cytoplasm, DNA, endoplasmic reticulum (ER), Golgi complex, lysosomes, mitochondria, Nucleus, ribosomes, vacuole, vesicles

Correct cell structures

Functions/definitions

all the material inside the plasma membrane, but outside the nucleus

carry proteins from the ER to the Golgi complex

composed of RNA and proteins; ‘workbench’ for protein synthesis fluid filled sac(s) that regulate the cell’s water content, support the

cell, and/or store certain substances

found inside the nucleus; genetic material

give plants their green color; involved in photosynthesis

isolates the cell, regulates flow of material, and allows interaction.

“powerhouse of the cell” They take the energy out of food.

1. separates molecules according to destination, 2. modifies some, and 3. packages materials into vesicles to transport to other parts of the cell

synthesize(s) different kinds of molecules (proteins, lipids, etc.)

support and protect otherwise fragile cells usually the largest organelle in the cell with three readily

distinguishable parts vesicles that contain digestive enzymes (and thus digest food

particles into simpler molecules)
