Homeostasis and Cell Organelles

James’ teacher mentioned that vesicles work with the cell membrane to transport proteins and maintain homeostasis.

Which statement CORRECTLY explains how the vesicle works with the cell membrane?

• Vesicles receive proteins from the chloroplast where the vesicle then travels to the cell membrane to be released out of the cell.

• Vesicles receive proteins from the cytoplasm where the vesicle then travels to the cell membrane to be released out of the cell.

• Vesicles receive proteins from the mitochondria where the vesicle then travels to the cell membrane to be released out of the cell.

• Vesicles receive proteins from the endoplasmic reticulum where the vesicle then travels to the cell membrane to be released out of the cell.

A student claims that the nucleus and ribosomes work together in the production of proteins.

Which statement CORRECTLY evaluates the student’s claim?

• The student’s claim is correct because the nucleus provides energy to create proteins and the ribosome can transport the proteins.

• The student’s claim is correct because the nucleus contains the instructions for making proteins and the ribosome serves as the pathway for protein transport.

• The student’s claim is correct because the nucleus contains the instructions for making the proteins while the ribosomes on the ER reads and synthesizes those instructions.

• The student’s claim is correct because the nucleus controls the cell and the ribosome packages the proteins.

The ____ ____ regulates what enters and leaves the cell and also protects and supports the cell.

• Golgi Apparatus
• ER
• cell wall
• cell membrane

How do the vacuole and cell membrane work together to maintain homeostasis within the cell?

• One absorbs sunlight, and the other uses the sunlight to create energy for the cell.

• One lets water in and out of the cell, and the other stores water for later use.

• One creates enzymes that are used to break down toxins that attach to the other

• One stores DNA and uses it to create the proteins that make up the other

Which of the following is the most accurate statement comparing cell membranes and cell walls?

• Cell membranes function mostly as selectively permeable

  gatekeepers while cell walls function mainly as support systems.

• Cell membranes are found only in animal cells; cell walls are found only in plant cells.

• Cell walls prevent everything from entering the cell, while cell

  membranes allow some things to enter.

• Cell walls function mostly for photosynthesis while cell

  membranes function mostly for cellular respiration.

A student is studying cell structures and organelles. He wants to create an explanation of how the various organelles interact to meet the cell’s need for proteins while preventing too many proteins from collecting inside the cell. Which of the following would be the BEST explanation for the student to use?

• The ribosomes that cover the rough endoplasmic reticulum

  manufacture proteins. These proteins are sent to the Golgi

  apparatus where they are modified and sorted based on their

  destinations. Proteins no longer needed by the cell are broken down by lysosomes.

• The surface of the smooth endoplasmic reticulum manufactures proteins. These proteins are sent to the Golgi apparatus where they are modified and sorted based on their destinations. Proteins no longer needed by the cell are broken down by lysosomes.

• The ribosomes that cover the rough endoplasmic reticulum

  manufacture proteins. These proteins are sent to lysosomes

  where they are modified and sorted based on their destinations. Proteins no longer needed by the cell are broken down by the Golgi apparatus

• The ribosomes that cover the Golgi apparatus manufacture proteins. These proteins are sent to the smooth endoplasmic reticulum where they are modified and sorted based on their destinations. Proteins no longer needed by the cell are broken down by lysosomes.

Which describes an interaction between the Golgi apparatus and another organelle to maintain a cell's homeostasis?

• The Golgi apparatus stores nutrients provided by the

  mitochondria.

• The Golgi apparatus collects genetic information to be used by

  the nucleus.

• The Golgi apparatus sorts and packages proteins created by

  ribosomes.

• The Golgi apparatus sends and receives chemical signals for

  the membrane.
