Scientific Name: Elodea Species: Plant

Description

OBJECTIVES:
Cytoplasm is the fluid material encased by the plasma membrane of a cell. Cytoplasm does much of the work of a cell by moving intracellular organelles. Cytoplasm is a heterogeneous material that is able to change its viscosity. Cytoplasmic streaming is the flowing movement of cytoplasm, internal and external to the plant cell, in a rapid orderly fashion. In plant cells, cytoplasmic streaming carries chloroplasts, which are the sites of photosynthesis, from one part of the cell to another. This helps maximize photosynthesis and subsequent cell growth. The objective of this experiment was to observe cytoplasmic streaming in the aquatic plant Elodea by low power microscopy.
