Hydrophytes Hydrophytes are plants that live in aquatic habitat. Hydrophytes can be divided into two types; fully submerged in water or partially submerged in water. These plants can absorb much water as they live in water habitat. Hydrophytes have various features in order to adapt in the aquatic environment in terms of morphological and anatomical adaptations. The morphological adaptations are divided into roots‚ leaves and stems. The roots of hydrophytes may be absent or poorly developed as

The aim of the present study is to use detail diagnostic characters and instrumental validation for authentication of a traditionally important herbal drug known as “Vidari” in local Indian market. Vidari drug has four different botanical entities namely Pueraria tuberose DC (P.t) (family: Leguminosae)‚ Ipomoea mauritiana Jacq (I. m) (family: Convolvulaceae)‚ Adenia hondala de Wide (A. h) (family: Passifloraceae) and Cycas circinalis (C. c) Linn (family: Cycadaceae). In this study morphological

SNAB includes a lot of material because it helps you to understand ideas or because it is interesting‚ but it can be a little confusing when it comes to knowing what to

Cell Organelles Nucleus Its function is to control the cell’s activities and retain the chromosomes. The nucleus is bound by a double membrane‚ the nuclear envelope. The nuclear envelope has pores in it to allow the transport of mRNA. The cytoplasm like material is called nucleoplasm which contains chromatin (coils of DNA and histone proteins)‚ it is chromatin that condenses to form chromosomes during cell division. Within the nucleus is a small spherical body called the nucleolus which

cohesion of water affects the functioning of living organisms is present in plants. Evaporation from the leaves in plants pulls water up from the roots. Cohesion due to hydrogen bonding helps hold the column of water molecules together within the xylem vessels located in the stem or trunk of a plant. Adhesion helps the process by resisting the pull of gravity against the upward motion of

Compare and Contrasting Plants and Animals Man has come a long way from the caveman days and so has our understanding of the world around us. Humans have always used plants and animals in one capacity or another‚ yet when a person thinks of the phrase ’plants and animals’‚ they automatically begin thinking about the differences between the two. Well I say that plants and animals have been known far too long for their differences. And as different as they seem‚ plants and animals are very

bloodstream was supposed to run through. One of its functions is to carry oxygen from the lungs to the cells in the body‚ allowing the cells to perform cellular respiration. The roots intake specific compounds from the soil‚ which are carried through the xylem to the leaves. There‚ they are used in the process of photosynthesis to create glucose as a source of energy. The glucose is carried throughout the plant through the phloem. Food/Energy Processing Food (meat‚ plants‚ etc) is eaten by the animal organisms

traits that characterize modern vascular plants. Explain how these characteristics have contributed to their success on land. a. Dominant sporophytes – As a result‚ the gametophyte became practically invisible to the human eye. b. Transport in xylem and phloem – These allowed plants to transport minerals‚ water‚ and other organic compounds‚ allowing plants to grow taller and thicker. c. Evolutions of roots – Roots are organs that provide better anchor for vascular plants for growing taller and

Osmosis in Plants Outline: To investigate the effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and a potato chip of a given size. Definition - Osmosis: Movement of a solvent (liquid) through a semi-permeable membrane separating solutions of different concentrations. The solvent passes from a less concentrated solution to a more concentrated solution until the two concentrations are equal. All
