Describe the processes occurring in the pictures

Part -1:

Matching: Match the phase of the cell cycle to its description and write the correct word. Some will be used more than once.

G1        S          G2        G0        Prophase                     Prometaphase             Metaphase     

Anaphase                    Telophase                    Cytokinesis

____________________1.          Chromosomes are replicated. S

____________________2.          The cytoplasm is divided. Cytokinesis

____________________3.          Chromosomes “relax” into chromatin. Telophase

____________________4.          The chromosomes are at the cell equator. Metaphase

____________________5.          The nuclear membrane disappears from view. Prometaphase       

____________________6.          The spindle apparatus begins to form. Prophase

____________________7.          The sister chromatids are pulled apart. Anaphase

____________________8.          The kinetochores attach to the spindle apparatus

____________________9.          Genes are transcribed to make mRNA.

____________________10.        The cell is not dividing, although it may be metabolizing.

____________________11.        The microtubules attached to kinetochores get shorter.

____________________12.        A checkpoint occurs during this phase.

____________________13.        Nuclear envelope forms around DNA. Telophase

____________________14.        Chromatin condenses to form distinct chromosomes. Prophase

____________________15.        The cell grows during this phase. G1

Part -2: Cell Transport Worksheet

Complete the table by checking the correct column for each statement:

Statement

Isotonic solution

Hypotonic solution

Hypertonic solution

Causes a cell to swell

 

 

 

Doesn’t change the shape of a cell

 

 

 

Causes osmosis

 

 

 

Causes a cell to shrink

 

 

 

Match the term with its correct description:

a.   energy                             e. active transport

b.   facilitated diffusion           f. exocytosis

c.   endocytosis                      g. carrier protein

d.   passive transport            h. channel protein

________ Transport protein that provides a tunnel-like opening in the plasma membrane through which particles can diffuse
________ Is used during active transport but not passive transport
________ Process by which a cell takes in material by forming a vesicle/vacuole around it
________ Particle movement from an area of higher concentration to an area of lower concentration
________ Process by which a cell expels wastes from a vesicle/vacuole
________ A form of passive transport that uses transport proteins
________ Particle movement from an area of lower concentration to an area of higher concentration
________ Transport protein that changes shape when a particle binds with

Label the diagrams of cells using the following terms: diffusion, active transport, osmosis, equilibrium. The arrows show the direction of transport. You may use the terms more than once!

Osmosis Practice Activity

Osmosis is the diffusion of water from an area of high concentration to an area of low concentration. Only water moves in osmosis! The diagrams below show the concentration of water and salt inside the cell and the concentration of water and salt surrounding the cell. Complete the sentences below by comparing the concentration of the water inside the cell and the concentration outside the cell.

a. Water will flow _____________________ (into the cell, out of the cell, in both directions).
b. The cell will ______________________ (shrink, burst, stay the same).
2

a. Water will flow _____________________ (into the cell, out of the cell, in both directions).
b. The cell will ______________________ (shrink, burst, stay the same).

a. Water will flow _____________________ (into the cell, out of the cell, in both directions).
b. The cell will ______________________ (shrink, burst, stay the same).

4. At which solution of concentration gradient is each cell diagram? (Hypotonic, Hypertonic, Isotonic)
