100% water Part D: Application 4% water 1. The paramecium (see Figure 3-1) is a single-celled organism. Go to the web and look up this organism. Now select an answer from each blank. H2O (iso-, hypo-, or nucleus oral groove Paramecia live in a(n) hypertonic) environment. In this environment, the paramecium takes in a lot of water through the process of (osmosis, diffusion, facilitated diffusion, or active transport). In order to get rid of this excess water, the paramecium has a specialized organelle called the contractile vacuole that acts as a water pump -contractile vacuole to expel water through the process of (osmosis, diffusion, facilitated diffusion, or active transport).

MAIN IDEA: Eukaryotic cells have an extensive and dynamic framework called a cyto- skeleton. The cytoskeleton is used for cell shape, internal structure, movement, and cell division. Many cells are surrounded by and supported by a complex extracellular matrix and are able to interact with adjacent cells and the environment via cell junctions. 5. List three common components of microtubules and microfilaments.

For each of the following scenarios please describe which part of the cell theory is supported by this evidence. Options: • • • Cells come from preexisting cells, cells are the basic unit of life, all living things are made of cells 1. A botanist (plant scientists) named Schlieden studied a large variety of plant cells under the microscope and found that all plants were made of cells. Option 1 2. A scientist named Leeuwenhoek found that after studying a wide variety of organisms the smallest living organism he observed was made of only one cell. Option 1 3. A scientist named Virchow viewed cells under a microscope and found that cells would grow and split into new cells. Option 1 4.

please choose correct letter and explain a bit 1. The strongest way by which a protein can maintain its shape is by using:a) ionic bonds b) disulfide bonds c) star war forces d) van der Waals forces 2. If a cell (like an amoeba) would be capable of migrating from one place to another only with movement created from the inside of the cell, then we can say that that movement is done mainly by:  a) glycoproteins b) feet c) microtubules d) actin filaments   True or False: In eukaryotic cells (such as human cells), the variety and diversity of proteins is much less than the variety and diversity of lipids.
