Cell Structures Cloze Fill in the blanks with words from the box. cells mitochondria plant chloroplasts nucleus vacuoles energy organelles wall membrane photosynthesis water All living organisms are composed of microscopic building blocks called _________________. These cells have many different basic structures in common called _________________. For example, cells are surrounded by a cell _________________ which controls the materials that move in and out of a cell. Another structure that most cells have in common is a _________________ in the center of the cell, which Cells seen under the microscope. Note how the nucleus of one cell is splitting. contains the blueprints for the cell’s growth and reproduction. Cells also have structures called _________________ that break down food and supply _________________ for the cell to use. _________________ are structures that store food and _________________ for the cell to use later. Although plant and animal cells have many similarities there are also some important differences. _________________ cells usually have one very large vacuole. This large vacuole helps prevent drying out during dry spells. Plant cells also have a thick cell _________________ surrounding them as well as a cell membrane. Another difference between plant and animal cells is that plants have organelles called _________________, which help plants capture the sun’s energy to be used for _________________.
