12) The _______________ is found in plant cells and goes through the process of photosynthesis.
13) The gel-like _______________ surrounds all the other organelles and helps hold the cell
together.
14) The _______________ stores food, water and waste. These are usually larger in plant cells.
15) The _______________ cleans up the cell by digesting waste. It is only found in the animal cell
and sometimes called suicide sacs because they destroy old cells.
16) In the animal cell only, the _______________ helps divide the cell during mitosis.
17) The _______________ packages proteins and acts like the U.P.S. of the cell.
18) The _______________ surrounds just the plant cells, giving them extra protection and support.
19) The _______________ surrounds ALL cells and is selectively permeable, which means it
decides what goes in and out of the cell.
20) The _______________ produces the proteins by translating the mRNA message.
21) The _______________ goes through cellular respiration to break down food for cell energy. It's
the powerhouse of the cell.
22) The _______________ are tiny cell structures that carry out specific functions within a cell.
23) The _______________ is the brain of the cell, that controls everything else.
24) The _______________ are maze-like tubules that run throughout the cell and transport proteins
and other materials.
