Liquid bubbles

The bubble-like structure in the cytostyle, with a liquid bubble membrane outside, has a similar structure and characteristics to the cell membrane, with selective pass-through, which separates the cell fluid from the cytostyte. Liquid bubbles are one of the remarkable properties of plant cells. In the early plant cells, the liquid bubble is not obvious, small but many, with the growth of cells, the liquid bubble gradually expanded, and finally joined each other to form a large central liquid bubble, and the cytostyte squeezed into a thin layer along the cell wall, the nuclei are often close to the side of the cell wall. In mature cells, liquid bubbles can account for up to 90
of
. The bubble contains cell fluid, and its composition is complex. Liquid bubbles are stored and excreta of plant cells, on the one hand, nutrients (e.g. sucrose, inorgic salts, etc.) can be stored in the bubble, on the other hand, plant metabolism formed by the non-use of substances (such as calcium grass acid, etc.) are also excreted into the cell fluid. Liquid bubbles are associated with the penetration of plant cells to absorb water. There are no obvious liquid bubbles in higher animal cells, and food bubbles and telescopic bubbles in some single-celled primary animals have the function of ingesting nutrition and excretion of waste, which can be said to be a form of liquid bubbles.
