Intracellular digestion can also refer to the process in which animals that lack a digestive tract bring food items into the cell for the purposes of digestion for nutritional needs. This kind of intracellular digestion occurs in many unicellular protozoans, in Pycnogonida , in some molluscs , Cnidaria and Porifera .
He coined the term cell (from Latin cellula, meaning "small room" [41]) in his book Micrographia (1665). [42] [40] 1839: Theodor Schwann [43] and Matthias Jakob Schleiden elucidated the principle that plants and animals are made of cells, concluding that cells are a common unit of structure and development, and thus founding the cell theory.
In Chara coralina, cells can grow up to 10 cm long and 1 mm in diameter. [8] The diameter of the vacuole can occupy around 80% of the cell's diameter. [11] Thus for a 1 mm diameter cell, the vacuole can have a diameter of 0.8 mm, leaving only a path width of about 0.1 mm around the vacuole for cytoplasm to flow.
The parenchymal cells include myocytes, and many types of specialised cells. The cells are often attached to each other and also to their nearby epithelial cells mainly by gap junctions and hemidesmosomes. There is much variation in the types of cell in the parenchyma according to the species and anatomical regions.
Lipid metabolism also occurs in plants, though the processes differ in some ways when compared to animals. [8] The second step after the hydrolysis is the absorption of the fatty acids into the epithelial cells of the intestinal wall. [6] In the epithelial cells, fatty acids are packaged and transported to the rest of the body. [9]
Original - This is a schematic view of an typical animal cell. An animal cell is a form of eukaryotic cell that makes up many tissues in animals. Reason well labeled, encyclopedic, high quality SVG. i am renominating it sepratly because last time it was one of the concern.

Plant cells have cell walls and a cell membrane,unlike plant cells,animal cells don't have cell walls,this makes it harder to stack animal cells.This is also another reason that plants stand tall and firm.Another thing that seperates these two cells is that plant cells have chlorapast and animal cells don't when the chlorapast dies the plant or ...
