Cells and Cell Transport

Cell definitions

ribosomes- synthesizes (makes) proteins mitochondria- makes the energy that powers the cell cell membrane- controls how water enters or leaves the cell cell wall- protects plants cells by covering the cell membrane nucleus- contains your chromosomes (DNA) and controls the cell chloroplasts- site of photosynthesis in a plant cell prokaryote- cells that lacks a nucleus eukaryote- cells with a membrane surrounding DNA 

   In order to receive the proper nutrients, an amoeba brings in its food through endocytosis. This process uses the energy created by the cells mitochondria. This is an example of which type of transport?   a. Osmosis      b. Passive transport    c. Diffusion    d. Active transport 

Which of the following does not require energy?   a. Diffusion   b. Endocytosis   c. Active Transport   d. sodium-potassium pump

The sodium-potassium pump requires energy to move sodium and potassium ions across the cell membrane from an area of low concentration to an area of high concentration. Which of these describes the process used  by the sodium-potassium pump?   a. Passive Transport    b. Active Transport    c. Osmosis    d. Diffusion

As a result of passive transport, the concentration of many types of substances...   a. Always remains greater inside a membrane  b. Eventually becomes balanced on both sides of a membrane  c. Always remains greater outside of a membrane  d. Becomes imbalanced on both sides of a membrane 

The cell membrane of a red blood cell will allow water, oxygen, and carbon dioxide to pass through it, but nothing else. Because some things are blocked from entering, this membrane is called...   a. non-permeable b. selectively-permeable  c. non-conductive  d. fully-permeable

Which method of a cell transport involves the movement of ANY molecule from an area of high to low concentration?   a. Active Transport  b. Diffusion  c. Endocytosis d. Exocytosis

Which method of cell transport involves the movement of WATER molecules from an area of high to low concentration?   a. Osmosis b. Facilitated Diffusion c. Endocytosis  d. Exocytosis

Osmosis and Diffusion are examples of...   a. Active Transport  b. Passive Transport  c. Simple Transport  d. Mitochondrial Transport  

Cell Transport Vocab.

Cell Membrane- 2 layers of fats that control what goes into and out of a cell Homeostasis- balance  Passive Transport- movement of molecules from high to low without the use of energy Active Transport- movement of molecules from low to high with the use of energy High Concentration- molecules closely packed together Low Concentration- molecules that are spread out Equilibrium- equal concentration on both sides of the cell membrane  Protein Pump- pump used to move molecules from high to low concentrations Diffusion- movement of ANY molecule from high to low concentration Osmosis- movement of WATER molecules from high to low Endcytosis- type of active transport where molecules are brought INTO a cell Exocytosis- type of active transport where molecules are EXITING the cell

To enter or leave a cell, molecule, like water, must pass through the...   a. Mitochondria  b. Ribosomes  c. Cell Membrane  d. Nucleus

Which of the following organelles is correctly paired with its specific function?   a. Ribosomes- production of energy b. Cell Membrane- maintains homeostasis c. Chloroplasts- transport of materials d. Mitochondria- site of photosynthesis

Bacterial cells are prokaryotic. Compared to eukaryotic cell, they would...   a. lack a nucleus  b. lack a cell membrane  c. have a smaller nucleus d. have a greater variety of organelles

After a cell was treated with a certain chemical, the ribosomes stopped functioning. Predict which cell activity would be immediately affected by this change in the ribosomes function.   a. Protein Synthesis b. Cellular Transport  c. Energy Production  d. Removal of Wastes
