Cell Parts and Membrane Transportation

5 Written Questions

1. solution that has the same concentration of solute as the cells it surrounds
2. fibrous protein filaments used for structural support
3. the difference in concentration between two regions
4. carrier-mediated transport that works against the concentration gradient and requires energy
5. make energy for the cell by converting O2 and glucose to CO2, H2O and ATP

5 Matching Questions

1. rough endoplasmic reticulum
2. phagocytosis
3. ribosome
4. nucleus
5. vacuoles

1. a anchors ribosomes in protein synthesis, accepts and modifies newly transcribed proteins and sends to golgi apparatus
2. b contains DNA, controls cell activities, including cell division
3. c endocytosis of large particles
4. d site of protein synthesis
5. e large vesicles. In plants, function to store water and nutrients, help support plant due to Turgor pressure

5 True/False Questions

1. solvent → the liquid that dissolves the solute in a solution

   True        False

2. nucleolus → site of rRNA production and ribosomal subunit assembly in nucleus

   True        False

3. endocytosis → opposite of endocytosis. Vesicle inside cell fuses with cell membrane, depositing contents on the outside.

   True        False

4. turgor pressure → hydrostatic pressure due to a plant being placed in a hypotonic solution. Is pressure on inside of plant cell against the cell wall.

   True        False

5. flagella → *in plants cells only, pigment containing vesicles in plants that function in photosynthesis. Most famous= chloroplast

   True        False
