The placenta is a disc-like tissue that develops between the uterine wall and embryo allowing the diffusion of nourishment from the mother’s blood to the growing fetus and waste disposal from the fetus to the mother. It receives oxygen, glucose, amino acids, lipids, vitamins, mineral ions and antibodies from the mother’s blood and removes carbon dioxide and urea from the fetal blood. The umbilical cord containing blood vessels connects the placenta to the fetus. It aloows the exchange of nutrients and waste products.

Heterotrophic nutrition refers to the mode of nutrition in which organisms rely on other organisms for food. It can be classified into three main types – holozoic nutrition, saprotrophic nutrition, and parasitic nutrition. Holozoic nutrition involves the ingestion, digestion and absorption of complex organic material. The saprotrophic nutrition obtains its nutrients from decaying organic material, while parasites obtain their food nutrition from living hosts.

Photosynthesis is the process by which green plants, algae and some bacteria convert light energy into chemical energy in the form of organic compounds such as glucose. This process occurs in chloroplasts where chlorophyll absorbs light energy and converts it into chemical energy. Raw materials required for photosynthesis include carbon dioxide and water, which are converted into glucose and oxygen through a series of chemical reactions. The process of photosynthesis is divided into three phases: Absorption, Conversion and Reduction.
