BIO 156 – Observing Eukaryotic Cells Lab Quiz (October 13)

Elodea

A plant cell known for its chloroplasts that carry out photosynthesis.

Cell wall

A structure that provides support and protection to plant cells.

Chloroplasts

Organelles in plant cells that perform photosynthesis.

Central vacuole

An organelle that stores water and maintains turgor pressure in plant cells.

Cytoplasmic streaming

The movement of cytoplasm that aids in chloroplast distribution within a cell.

Amyloplasts

Starch-storing structures found in potato cells.

Iodine test

A method used to detect the presence of starch; positive result is indicated by a blue-black color.

Red onion cells

Plant cells that contain pigments in the central vacuole, giving them a reddish-purple color.

Cheek epithelial cells

Animal cells that do not have a cell wall or chloroplasts but contain a nucleus and cytoplasm.

Cilia

Hair-like structures on Paramecium that assist in movement and feeding.

Contractile vacuoles

Organelles in Paramecium that expel excess water.

Prokaryotic cells

Cells that lack a nucleus and membrane-bound organelles, typically smaller than eukaryotic cells.

Eukaryotic cells

Cells that have a nucleus and membrane-bound organelles, typically larger and more complex.

Staining

A technique used to increase contrast in microscopy, making structures like nuclei more visible.

Field diameter

The size of the viewable area under a microscope used to estimate specimen size.
