Concepts

Major Concept

Locomotion in the microscopic world.

Minor Concept

1.      Pseudopodia are the locomotory organs in the unicellular organisms like amoeba and it is the extensions of cytoplasm towards the direction of movement.

2.      Cilia is the hair like cytoplasmic filaments seen on the surface of the cell of paramecium and this rhythmic movement makes locomotion possible.

Introduction          Teacher talks friendly with the students and asks some questions to check their previous knowledge.      Can you move from one place to another?      Is the humans can only move from place to place?      Then which are the other organisms that are able to move?    Let us learn about the locomotion in microorganisms. Presentation Activity I     Teacher presents a soliloquy of amoeba and told the students to read it. Discussion Hints 1.      Name one unicellular organism?      2.

Discussion Hints 1.      Which is the locomotory organ of paramecium? 2.      What is cilia? Activity III  Teacher told the students to observe the movement of euglena under a microscope. Discusssion Hints 1.What is the locomotory organ of euglena? 1.      How does euglena moves in a fluid medium?  Summarization                       Students understand the locomotion of organisms through videos and observations through microscope. Amoeba (CB)           Pseudopodia (CB) Cilia (CB)                 Paramecium (CB) Euglena (CB)              Flagella (CB)

MEDICINAL PLANTS

The use of plants as medicine predates written human history. Many of the herbs and spices used by humans to season food also yield useful medicinal compounds. The use of herbs and spices in cuisine developed in part as a response to the threat of food-borne pathogens. Studies show that in tropical climates where pathogens are the most abundant, recipes are the most highly spiced. Further, the spices with the most potent antimicrobial activity tend to be selected. In all cultures vegetables are spiced less than meat, presumably because they are more resistant to spoilage.^[  Angiosperms (flowering plants) were the original source of most plant medicines. Many of the common weeds that populate human settlements, such as nettle, dandelion and chickweed, have medicinal properties.

A large amount of archaeological evidence exists which indicates that humans were using medicinal plants during the Paleolithic, approximately 60,000 years ago. (Furthermore, other non-human primates are also known to ingest medicinal plants to treat illness)^] Plant samples gathered from prehistoric burial sites are an example of the evidence supporting the claim that Paleolithic peoples had knowledge of herbal medicine. For instance, a 60 000-year-old Neanderthal burial site, "Shanidar IV", in northern Iraq has yielded large amounts of pollen from 8 plant species, 7 of which are used now as herbal remedies. Also medicinal herbs were found in the personal effects of Ötzi the Iceman, whose body was frozen in the Ötztal Alps for more than 5,000 years. These herbs appear to have been used to treat the parasites found in his intestines.

Medicinal plants have been identified and used throughout human history. Plants have the ability to synthesize a wide variety of chemical compounds that are used to perform important biological functions, and to defend against attack from predators such as insects, fungi and herbivorous mammals. At least 12,000 such compounds have been isolated so far; a number estimated to be less than 10% of the total. Chemical compounds in plants mediate their effects on the human body through processes identical to those already well understood for the chemical compounds in conventional drugs; thus herbal medicines do not differ greatly from conventional drugs in terms of how they work. This enables herbal medicines to be as effective as conventional medicines, but also gives them the same potential to cause harmful side effects.

The use of plants as medicines predates written human history. Ethnobotany (the study of traditional human uses of plants) is recognized as an effective way to discover future medicines. In 2001, researchers identified 122 compounds used in modern medicine which were derived from "ethnomedical" plant sources; 80% of these have had an ethnomedical use identical or related to the current use of the active elements of the plant. Many of the pharmaceuticals currently available to physicians have a long history of use as herbal remedies, including aspirin, digitalis, quinine, and opium.

The use of herbs to treat disease is almost universal among non-industrialized societies, and is often more affordable than purchasing expensive modern pharmaceuticals. The World Health Organization (WHO) estimates that 80 percent of the population of some Asian and African countries presently use herbal medicine for some aspect of primary health care. Studies in the United States and Europe have shown that their use is less common in clinical settings, but has become increasingly more in recent years as scientific evidence about the effectiveness of herbal medicine has become more widely available.
