The Simple cuboidal epithelium<span> forms thyroid gland and secretes hormones is shown in the picture attached.

Although algae can photosynthesize, they lack other defining characteristics of plants such as true roots, stems and leaves, so they are not part of the plant kingdom.
Osmosis is a vital function to the growth and stability of plant life. Without osmosis, photosynthesis would never occur and plants would wilt and die. Osmosis distributes water through selectively permeable membranes to maintain this proper volume and pressure of all plant cells.
I would just recommend looking up a diagram of a cell, that should help and you should get all the necessary answers
