After each description, fill in the appropriate structure: “powerhouses” of the cell:_______ ; capture solar energy: _______; structure outside of animal cells:_________; region of prokaryotic cell containing DNA:________; propel fluid past cells:_________ ;consists of the cytosol and the organelles within it:

While eukaryotic cells are generally larger than prokaryotic cells, metabolic requirements place upper limits on how large eukaryotic cells can become. Which of the following statements does not accurately describe this? As multicellular organisms grow in size, they do not have larger cells; rather, they have a larger number of cells. As a cell increases in size, the surface area grows faster than volume. If a cell is too large, there will not be enough surface area for the exchange or elimination of oxygen, nutrients, and wastes. The surface area to volume ratio must remain as large as possible

Label the animal cell below: 1 is meant for the large blue structure. 2 is meant for the yellow and blue structure. 3 is meant for the orange structure around the cell. www.fiandenum : Mitochondria : Cell membrane : Cell wall : Nucleus : Chloroplast 7.
