(2) Take another tomato, scald it with boiling water, tear off a thin layer of epidermis, and observe it under a microscope. It is found that the cells are arranged closely, and this layer of epidermis belongs to protective tissue; The inner part of the epidermis is dental pulp cells. Microscopically, the cell wall is thin and scattered, belonging to vegetative tissue.
(3) Cut the pulp and find some white "tendons". Take a "tendon", wash off dental pulp cells, make a temporary piece, gently press it, and then observe it under a microscope. It is found that the cells are connected one by one, and there are many small holes in the cell wall in the middle. You estimate that this part of the structure may be meristem.
(4) According to the above observation, Xiao Ming draws the conclusion that tomato is a tomato made up of various tissues in a certain order, and it is an organ made up of various tissues in a certain order.
