Title: To investigate the reproductive structures of the plants and to understand its importance in the survival of plant species. Introduction: Angiosperms are the dominant form of plant life in most terrestrial ecosystems, comprising about 90 percent of all plant species. Most crop and ornamental plants are angiosperms. Their success results, in part, from two innovative structures: the flower and the fruit. Flowers are derived evolutionarily from modified leaves. The main parts of a flower…

The mulch is usually requested from Madison Park. It is composed of chipped, compost, shredded leaves, manure and straw. The decomposers in mulch will break down the organic matters in mulch and convert it into inorganic nutrients that the plants need. First of all, we cleared the area by removing the invasive species and weeds. Then, we put coffee bags to cover the whole area and wait for mulching. When people look closer to the mulch, people can often see vapor is releasing from the mulch…

green plants and some different life forms use daylight to provide foods from carbon dioxide and water. Photosynthesis in plants includes the green color chlorophyll and produces oxygen as a result (What is Photosynthesis, P.1). Plants also use photosynthesis to create sugar. The sugars fuel a plant's roots, stems, and leaves so the plant can grow. It attempts to preform photosynthesis with leaves absorbing the sun’s light and then make the sugars within the chlorophyll located in the plant as…

soil is a major source and natural medium for plant growth which has a direct impact on yield and quality of crops growing on it. 2.1.1 Nutrients in soil Most plants raise by absorbing nutrients from the soil. Soil is a major source of nutrients needed by plants for growth and development. There are two main classification of nutrients in the soil; Macronutrients and Micronutrients. Carbon (C), Hydrogen (H), and Oxygen (O) are also essential for plant growth, but not considered as soil…

an attractive model system for plant biology and functional genome analysis.(1-7) It shares many biological features with higher plants (vascular plants) but has the unique advantage of an efficient homologous recombination system for its nuclear DNA.(2,3) This allows precise genetic manipulations and targeted knockouts to study gene function, an approach that due to the very low frequency of targeted recombination events is not routinely possible in any higher plant.(3) Mosses are situated…

B) Blackthorn (Prunus spinosa) Active components of the plant are believed to be polyphenols, including flavonoids, A-type proanthocyanidins, anthocyanins, coumarins, and phenolic acids, forming unique and diversified profiles in particular organs, among which the flowers are the least (Owczarek et al., 2017). This work is the first comprehensive phytochemical and activity study of the flower extracts of P. spinosa. (Phenolic compounds of blackthorn (Prunus spinosa L.) and influence of in…

Plants require certain substances that are necessary for their survival. These requirements are carbon dioxide, water and mineral nutrients. Mineral nutrients are essential chemical element that are critical for plants to sustain life function and complete their life cycle (Uchida, 2000). These nutrients are classified into two groups micro a macro nutrients. Micronutrients are elements are used in very small amount these include boron, chlorine, cooper, iron, manganese and zinc. While…

Cannabis sativa is a hemp plant which the popular drug marijuana comes from. The leaves, stems, and seeds from this plant can be formed into a dried leaf or hash used to smoke and also eat. In 2005 a survey was conducted by the National Survey on Drug Use and Health and it showed that 97.5 million Americans age twelve and older reported using marijuana at least once. Research studies also shows that about 9 percent of marijuana users become addicted. Tetrahydrocannabinol also known as "THC" is…

In Aristotle’s view, everything in this world can be categorized. Living beings include plants and animal. The plant has nutritive soul and the animal process both nutritive soul and perceptive soul. If we discuss animal further, we can divide animal into rational animal, which is human, and non-rational animal. The essential feature of “being an animal” is perception. From the Aristotle Introductory Reading: “413b2: What makes something an animal is primarily perception.” Perception is…

penetrate our body and spread throughout the body, bringing well-being and its properties to all corners. What are essential oils? Essential oils are substances found in different plant tissues. The ancient alchemists called them “soul of plants”, because they contain numerous natural chemical compounds, from the plant from which they are extracted, that we can use as a home remedy in many situations. In fact, aromatherapy is a very old technique that uses essential oils for therapeutic…
