pellets into each quadrant, followed by another layer of dirt. Finish by watering quadrants. After 2-3 weeks, count the parent generation number of trichomes and record. Then, choose 25% of the hairiest plants out of the P1 population and replant their seeds following the same directions earlier on. When plants are grown, follow the same steps and count trichomes and record. Compare both sets of P1 data to F1 data to determine if evolution took
Animal Cells Red Blood Cells Red Blood Cells (RBCs) are also known as erythrocytes. There are up to 4.2 - 6.2 million RBCs in a cubic millimetre of blood. They specialize in transporting oxygen around the body. As a result of this RBCs are small and have a biconcave shape to increase their surface are to optimize the amount of oxygen that diffuses across their cell membrane. As well as this RBCs have no organelles other than a cell membrane and cytoskeleton (in mammalian RBCs). After oxygen
Dermal Tissue System The dermal tissue system consist of epidermis and periderm whose cells contain protoplasm and nucleus without intercellular spaces. The dermal tissue system is theprotective outer layer for the whole part of plant. It acts like human skin which forms the first line of defence against physical damage and pathogen.A single tissue called epidermis, is a layer of tightly packed cell usually found in non-woody plant or herbaceous plants. The epidermis forms a protective cover in plant
metabolites which are known to contain essential oils that produces well-known scents in herbs belonging to the Lamiaceae plant family (Scott 2008). These scented compounds are usually found in the trichomes of basil, rosemary, lavender, etc. (Scott 2008). Electron micrograph images of these trichomes can be seen below. According to Keeling & Boltmann (2006), there are about 30 000 known types of terpenes which originated from structures created from terpene synthases. These terpene synthases can
of the plant or other parts of plants like leaf, flower, bark, etc.... They are some important families that contains volatile oils are Labiatae, Rutaceae, Myrtaceae, Piperaceae and Zingiberaceae. Volatile oil present in structures as glandular trichomes,
its adaxial side, which are stalked with mucus covered glands covering the leaves surface. The mucus like fluid on the tentacles is an acidic enzyme that assists in the digestion of the plants prey. This species is considered pubescent with many trichomes covering the majority of the plant. The flowers found on the cape sundew are simple, and generally come in colors of red, pink or white with each flower borne on a single stem. Each flower generally has 5 petals that are from 12-14 mm across. Stamen
Imtroduction- Histology is the study of the details of the biological cells or tissues in a specimen prepared by histological technique and by using electron or light microscope. It plays an important role in the fields of verternary,medicine,etc The word histology is derived from the greek word where histo means tissue and logy means study.therefore histology is the study of the tissues.therefore the person who performs histology by a framed set of procedures is called as a histologist. Histology
Project Proposal: AIMS - Bioinformatic approach to aid gene identification and characterisation in Arabidopsis thaliana - Evaluate and integrate the accuracy of Arabidopsis database INTRODUCTION: Arabidopsis thaliana is a model plant for research and has been used wisely to study many aspects of plant biology. There is significant amount of information about this plant in the database, such as fully sequenced and annotated genomic sequence, extensive expressional data and functional characterisation
A Biology Case Study on Whether Cannabis Should be reclassified to a Class B Drug Introduction: In this case study on cannabis, I am going to be exploring whether Cannabis, which is currently a Class C drug, should be reclassified to become a Class B drug. It is commonly thought that if Cannabis was reclassified, it would dissuade drug dealers and users from taking and selling the drug, as if caught with it a longer sentence and heavier fine would be enforced. I will also be discussing how easy
In the United States, marijuana is being categorized as a Class A Drug, but in reality marijuana has been known to help cure and fight many sicknesses and diseases. Marijuana is being criticized by people that never studied the drug or even know about the medicinal benefits from the drug. Over the years, marijuana has been called a gateway drug to harder narcotics, but this isn’t the case. Marijuana has many medicinal benefits that the media and government avoid releasing to the society but it's
Chapter-1 Introduction The worldwide demand for high potency sweeteners is expected to rise especially with the new practice of blending various sweeteners; the demand for alternatives is expected to increase. The sweet herb of Paraguay; Stevia rebaudiana Bertoni produces; in its leave;, such an alternative with the added advantage that stevia sweeteners are natural products. The sweet steviol glycosides have sensory & functional & properties superior to those of other high potency
