definition of growth is “An irreversible change in the organism‚ organ or cell is called growth”‚ which includes increase in mass weight or volume of living organism‚ it leads to development in plants. REGION OF GROWTH: Growth region is located at extreme apices of root‚ stem‚ leaf where we make out meristematic tissue. In addition to above‚ the region where intercalary and lateral meristem is present is also considered as growth region. PHASES OF GROWTH: Growth is a complex process where the dividing

SCIT 1407/BIOL 2401 Tissue Lab Practical 1 I. EPITHELIAL TISSUE: Only exists in three cell shapes – flat or squamous‚ cuboidal & columnar. This tissue covers or lines other tissues or produces tubes. Epithelial tissue always rests on a basement membrane. The characteristics are: lack of visible interstitial space‚ many cells‚ and no blood vessels. A. Simple Squamous: (kidney slide). Look in the outer edge or cortex of the kidney to find a Bowman’s capsule. The lining of the Bowman’s

the four tissue types found in the human body. Describe an example of each type with their function and location. The four main tissues in the human body are connective‚ epithelium‚ muscle and nervous tissue. Connective tissue is an abundant nonliving extracellular matrix‚ located throughout the human body; such as the head‚ tendons‚ bone‚ and many more. It is the most widespread tissue in the human body and is the most durable tissue type. There are so many functions for this tissue‚ that it

Should transgender children be allowed to receive hormone therapy? The term transgender is defined as the “non-identification with‚ or non-presentation of‚ the sex (and assumed gender) one was assigned at birth” and is one that describes an estimated 300‚000 to 500‚000 people in the UK of all age groups. We live in a Western culture where a distinct gender binary of either male or female exists‚ a social dichotomy that is enforced upon an individual from the day they are born‚ with their sex being

ENDOPHYTES: ARE TROPICAL LEAVES BIODIVERSITY HOTSPOTS? A. ELIZABETH ARNOLD1 AND F. LUTZONI Department of Biology‚ Duke University‚ Durham‚ North Carolina 27708 USA Abstract. Fungal endophytes are found in asymptomatic photosynthetic tissues of all major lineages of land plants. The ubiquity of these cryptic symbionts is clear‚ but the scale of their diversity‚ host range‚ and geographic distributions are unknown. To explore the putative hyperdiversity of tropical leaf endophytes‚ we compared endophyte

Background: Connective tissue nevi (CTN) are hamartomas in which components of the dermis (collagen‚ elastin‚ or glycosaminoglycans) are altered. Appear as firm‚ asymptomatic‚ skin-colored plaques composed of closely grouped papules with an orange peel-like surface texture. Previous classifications made based on which dermal component was found in excess‚ genetic patterns of inheritance‚ and +/- organ involvement fail to explain all reported cases. o Example: Buschke-Ollendorff syndrome

Myeloid tissue Is the bone marrow Why we discuss myeloid tissue/bone marrow? – because we want to study the development of blood cells. We called it HEMOPOEISIS/HEMATOPEISIS HEMOPEISIS/HEMATOPOEISIS –Blood cell formation (occurs in the bone group) Why study this? Because: there is a continuous replacement of cells they have short life span when they are in the peripheral circulation so‚ we have to study how these cells mature and differentiate Phases of hematopoeisis MESOBLASTIC PHASE
