What is Placenta – Class 10th Read More
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.

Multiple fission is a form of asexual reproduction observed in some unicellular organisms like Plasmodium, algae and some protozoans. This process involves the repeated division of the nucleus of a single parent cell, producing numerous identical daughter cells.Each daughter cell is encased in its own membrane. Multiple fission is a rapid process occurring during unfavourable conditions, increasing chances of survival and reproduction of organisms.

Binary fission is a type of Asexual Reproduction in which a single organism divides into two equal parts, each carrying one copy of the Genetic Material. This process is commonly found in single-celled organisms such as bacteria, archaea and some protozoa. Binary fission allows these organisms to reproduce quickly and efficiently without the need for a mate or Sexual Reproduction.

Paramecium, a tiny unicellular animal, feeds on microorganisms through holozoic nutrition. It has cilia to engulf food through the oral groove. The five steps are ingestion, digestion, absorption, assimilation and egestion. Paramecium can regulate food intake and selectively choose its food. It is a model organism for the study of nutrition in unicellular organisms.

Digestive glands are organs that produce digestive juices to help break down food and absorb nutrients. There are five main types of digestive glands in the human body: salivary glands, gastric glands, pancreas, liver and intestinal glands. Each gland has a specific function in the digestive process, such as producing enzymes or regulating blood sugar levels. Understanding the functions of these glands is essential for maintaining a healthy digestive system.
