also called protoplasmic streaming the movement of the fluid substance (cytoplasm) within a plant or animal cell. The motion transports nutrients, proteins, and organelles within cells. First discovered in the 1830s, the presence of cytoplasmic streaming helped convince biologists that cells were the fundamental units of life.

Although the mechanism of cytoplasmic streaming is not completely understood, …

>	cytoplasmic streaming the movement of the fluid substance (cytoplasm) within a plant or animal cell. The motion transports nutrients, proteins, and organelles within cells. First discovered in the 1830s, the presence of cytoplasmic streaming helped convince biologists that cells were the fundamental units of life.
>	Process of phloem transport from the angiosperm article Products of photosynthesis (primarily sugars) move through phloem from leaves to growing tissues and storage organs. The areas of growth may be newly formed leaves above the photosynthesizing leaves, growing fruits, or pollinated flowers. Storage organs are found in roots, bulbs, tubers, and stems. Thus the movement in the phloem is variable and under metabolic control ...
>	Structure of the thallus from the fungus article In almost all fungi the hyphae that make up the thallus have cell walls. (The thalli of the true slime molds lack cell walls and, for this and other reasons, are classified as protists rather than fungi.) A hypha is a multibranched tubular cell filled with cytoplasm. The tube itself may be either continuous throughout or divided into compartments, or cells, by cross walls ...
>	sarcodine any protozoan of the superclass (sometimes class or subphylum) Sarcodina. These organisms have streaming cytoplasm and use temporary cytoplasmic extensions called pseudopodia in locomotion (called amoeboid movement) and feeding. Sarcodines include the genus Amoeba (see amoeba) and pathogenic species, e.g., dysentery-causing Entamoeba histolytica. These protozoans' cells ...
>	Growth from the fungus article Under favourable environmental conditions, fungal spores germinate and form hyphae. During this process, the spore absorbs water through its wall, the cytoplasm becomes activated, nuclear division takes place, and more cytoplasm is synthesized. The wall initially grows as a spherical structure. Once polarity is established, a hyphal apex forms, and from the wall of the ...
