21. No you cannot get everything you need from a plant based diet.
If you go that route, you need vitamin supplements. Vegetarians in their 40 and 50 used to die because of the lack of B12
Humans are Omnivores, our teeth say so.

Unlike some other B vitamins, B12 is not found in any plant food other than fortified cereals. It is, however, abundant in many meats and fish, and in smaller amounts in milk and eggs. This makes it difficult for people following a strict vegetarian diet to get the necessary amount of vitamin B12.

Vitamin B12, an essential B vitamin, is of special interest to vegetarians since it is not found in any significant amounts in plant foods. In addition, vitamin B12 deficiency can result in detrimental changes in certain body functions. It is required for the normal maturation of red blood cells and also for the synthesis of the myelin sheath of nerve tissue.

It is important for vegetarians to make sure they get enough vitamin B12, an essential nutrient found only in animal products, including meat, dairy products and eggs. There are no reliable sources of vitamin B12 in vegetarian foods. Vitamin B12 analogues (substances similar to vitamin B12) are found in some plants, especially after they have been fermented with vitamin B12-producing yeast. These analogues, however, are not absorbed by humans, and may even block vitamin B12 absorption in those who follow a vegetarian diet.

And so on.
