The Cellular Structure of Life: Review • Cell wall:

________________________________________________of plants, fungi, most bacteria, and some protists; __________________________________________________

• Plasma membrane: serves as boundary between the cell and its environment; ____________________________________________________________________________________________________

The Cellular Structure of Life: Review cont.

• Cytoplasm: __________________________________________________in eukaryotic cells that suspends the cell’s organelles and is the site of numerous chemical reactions.

• Flagellum/Flagella: ____________________________________________________________composed of pairs of microtubules; found on some cell surfaces; they help propel cells and organisms by a whiplike motion.

The Cellular Structure of Life: Review cont.

• Chromosome: a subcellular structure that ______________________________________of the cell

• Nuclear membrane: ____________________________________________________________________________________

The Cellular Structure of Life: Review cont.

• Nucleus: the membrane-bound central structure of eukaryotic cells that ________________________________________________

• Mitochondria: eukaryotic

membrane-bound organelles that ____________________________________________________________________________________________________ has a highly folded inner membrane that produces energy-storing molecules.

The Cellular Structure of Life: Review cont.

• Endoplasmic reticulum: : organelle in eukaryotic cells with a series of highly folded membranes surrounded in cytoplasm; site of cellular chemical reactions; _____________________________________________.

• Vacuoles: membrane-bond fluid –filled space in the cytoplasm of plant cells used for the __________________________________________of materials.

The Cellular Structure of Life: Review cont.

• Lysosomes: attached to the vacuole and produce chemicals that ______________________________________ inside it

• Golgi apparatus: ______________________________________needed by the cells to carry out life functions.
