LE Review: The Cell

Hypertonic cells appear..

• shrunken

• swollen

• normal

• bursting

What 3 things does the Golgi apparatus do?

• 1. work with the endoplasmic reticulum
  2. modify proteins and package them
  3. aid in releasing proteins from the cell

• 2. synthesize DNA, break down waste, and produce energy

• 3. transport nutrients, store genetic information, and regulate cell division

• 4. create ribosomes, synthesize lipids, and detoxify harmful substances

Locate the mitochondrion in a plant AND animal cell:

• B. It is located in the cytoplasm of the cell.

• C. It is present in both plant and animal cells.

• D. It is only found in plant cells.

Which is true of a HYPOtonic solution?

• It contains less solute than the cell cytoplasm has

• It contains more solute than the cell cytoplasm has

• It has the same solute concentration as the cell cytoplasm

• It is isotonic to the cell cytoplasm

When water rushes into an animal cell, there is a possibility of it bursting.
Why would this be far less likely to happen in a plant cell?

• A plant cell has a cell wall

• A plant cell has a flexible membrane

• A plant cell contains more water than an animal cell

• A plant cell can expel excess water more efficiently

The endoplasmic reticulum is well known as an organelle associated with ____________________________.

• Transport

• Energy production

• Cell division

• Protein synthesis

Nicknamed the "control" center because it holds DNA the nucleus can be found where in plant and animal cells?

• In the cell membrane

• In the nucleus

• In the mitochondria

When water enters animal cells they may burst. Why would this be less likely in plant cells?

• Plant cells have cell walls in addition to cell membranes...

• Plant cells have cell walls in addition to cell membranes.

• Plant cells can expel excess water through their roots.

• Plant cells are less permeable to water than animal cells.

Name a characteristic of isotonic cells:

• Abnormal size and function

• Normal size and function

• Increased size and decreased function

• Decreased size and normal function

Explain simple diffusion in a cell:

• High to low concentration

• Movement against a concentration gradient

• High to low concentration

• Movement of water across a membrane
