2. what is the effect of a hypertonic solution on a plant cell?

  • net movement of water is out of the cell, causing it to shrink
  • net movement of water molecules is into the cell, causing it to burst.
  • net movement of water is out of the cell, causing it to become flaccid, and the cytoplasm to pull away from the cell wall, so that it is plasmolysed
  • water molecules move into and out of the cell in equal amounts, resulting in no changes to the cell.

3. what is cell signalling?

  • the communication between cells using a hormone and a complementary receptor site that will bring about a change in other cells
  • the name of the hormone that cells use to communicate with other cells or organelles
  • the changes that a cell experiences as a result of another cells actions
  • the communication between cells using a neurotransmitter and a complementary receptor site that will bring about a change in other cells

4. what is the difference between the RER and the SER?

  • RER transports proteins that were made on the attached ribosomes, and the SER is involved in the production of the proteins
  • RER transports proteins that were made on the attached ribosomes, and the SER is involved in the production of lipids
  • RER transports lipids that were made on the attached ribosomes, and the SER is involved in the production of lipids
  • RER makes proteins and SER makes lipids

5. Eukaryotes are about 100-1000um in diameter

  • no - they are 10-100um
  • True
  • no - they are 5-10um
  • no - they are 1000-2000
