Set the volume to be pipetted, using the volume adjustment knob Place a disposable tip on the micropipettor Place tip into empty microcentrifuge tube Insert tip just below the surface of the sample liquid, then slowly release the pushbutton Depress push button to first stop Depress push button through the first stop and to the second stop Remove tip from sample liquid Remove pipettor from microcentrifuge tube, then fully release the pushbutton

Plasma membrane - protect cell from it's surroundings. In both kinds of cells.

Cytoplasm - supports rounded cell structure, within it are all the organelles. Contains chemicals needed by the cell. In both kinds of cells.

Nucleus - contains DNA and is the control center of the cell. In both kinds of cells.

Nuclear envelope - surrounds nucleus, makes sure important molecules (DNA) stay within the nucleus. In both cells.

Nucleolus - makes ribosomes. In both cells.

DNA - genetic information for development and function. In both cells.

Rough ER - produces proteins. In both cells.

Smooth ER - makes and stores lipids (fats). In both cells.

Golgi body - sort and process macromolecules (proteins, lipids, etc). In both cells.

Ribosomes - makes proteins. In both cells.

Vacuoles - very large in plants, a storage center. In both cells.

Lysosome - digests and removes wastes. In both cells.

Mitochondria - energy powerhouse, produce ATP energy. In both cells.

Cytoskeleton - shapes, supports, and facilitates movement. In both cells.

Centrioles - cell division (form spindle fibers). Only in animal cells.

Cilia - movement for microorganisms. Only in animal cells.

Chloroplasts - photosynthesis, helps absorb sunlight and make food for the plant. Only in plant cells.

Cell wall - strength, structure, filters molecules going in and out of the cell. Only in plant cells.

Central Vacuole - holds materials and wastes, helps maintain proper pressure within the cell. Only in plant cells.

Hope this helps!
