Cell+Worksheet++I

1.-The cell is divided into 3 main parts. These are: a.- b.- c. 2. Two principal molecules make up the plasma membrane. These are: a.- b.- 3 and 4. The **Cytoplasm** is: (Choose the correct option) The fluid within the nucleus The fluid around the nucleus plus the organelles The fluid around the nucleus minus the organelles The fluid surrounding the cell

4. Label the parts of the cell in the diagram below. Use the labels: **Nucleus, Plasma membrane, Cytosol, Nuclear membrane, Ribosomes, Rough Endoplasmic Reticulum, Smooth Endoplasmic Reticulum, Golgi body, Mitochondrion, Lysosome, Centrioles, Nucleolus**

5. a. What is this organelle called? b. What is its function in the cell? 6 Match the structure with its function in the table below. 9. True or false? a. The cytosol consists mainly of water. T / F b. Ribosomes are found attached to the membrane of smooth endoplasmic reticulum (SER). T / F c. The cytoplasm consists of the cytosol plus organelles and cell inclusions. T / F d. Cellular respiration takes place in the Golgi bodies. T / F e. The chromosomes in the nucleus consist mainly of RNA. T / F f. The nuclear membrane consists of two layers like the plasma membrane. T / F g. Proteins made in the RER move to the centrioles for processing. T / F h. Lysosomes contain enzymes. T / F i. Glycogen and fat droplets are often found in the cytosol. T / F j. Ribosomes join fatty acids together to make lipids. T / F
