Epidermal cells on the outside of the cuticle epidermis foramen and hair
Epidermis present in young dicot stem from outside to inside is the hypodermis. Common cortex, endodermis, pericycle, vascular bundles, medullary rays and pith. The hypodermis, common cortex, and endodermis are considered to be part of the cortex. Epidermis: This is the outermost layer of the stem. The epidermis is uniseriate and consists of arranged parenchyma cells. Compactly intercellular spaces are absent.
Epidermal cells are elongated. in T.S. They appear rectangular-barrel shaped. The outer walls are usually convex and thick. The inner walls are flat or convex. They are thin. Epidermal cells are devoid of chloroplasts. That's why they are. transparent. A layer of cuticle is present on the outside of the epidermal cells. This reduces the rate of surface transpiration. In places the epidermis bears stomata and hairs.
The stoma contains kidney or kidney-shaped guard cells. Guard cells are small. They have chloroplasts. The cells present on the surface of the stem of the sunflower are multicellular and homogeneous. The surface of the hair is also covered by the cuticle.
Functions: (i) being the outermost, epidermis acts as a protective layer against internal exposure, (ii) it prevents pathogens from entering, (iii) reducing the rate of transpiration of the cuticle surface , (iv) Histone forms an insulating layer. By trapping air between them, (v) Stomata present in epidermis participate in gaseous exchange.
The number of vascular bundles of each type is more than 6, usually- several. The number of vaseular bundles of each type is 2-6. diarch is for xylem. hexagon. Xylem is polygamous. Phloem parenchyma is present. Phloem parenchyma is absent. In the outline of the xylem vessels are polygonal.
The xylem vessels are round or oval in shape. Connective tissues become thick walled. and sclerified. Conjunctival tissue forms the major part. Conjunctival tissue does not form any part of the vascular cambium. of the vascular cambium. The pit is small or lacking. The pit is quite large and well developed.
Such units are selected for study
The study is the in-depth study of a specific social structure or particular aspects of a social structure that includes various things such as the psychological characteristics of the individuals involved. In this the person being studied, a part of the individual's life, a single relational structure, a particular process or organization, the chosen entity may be negative, specific or extreme. Such units are selected for such study when other qualitative methods fail to take into account the most important aspects of the unit.
The steps in this method are as follows: Character Selection: The selection is based on the leadership of the characters. Determining the current state of the characters: Each character is described by a number of facts. These facts have been obtained from various sources. Information Note: Enhanced character information is noted in a way that is easily accessible.
Diagnosing the situation: To diagnose the situation or to form a hypothesis based on the information obtained about the characters. Imagination Imagination is verified by fact-checking what is in each character. Adaptation and Treatment: At this stage, counseling is given as per the diagnosis. imitative; Here the validity of treatment is checked, where treatment has failed, there is re-diagnosis and re-treatment.
For example, physics says that a thrown ball falls on the ground. Magnets attract iron. Idealistic Science: Idealistic science is the science that studies ideals. This science studies how a person or human being should behave. Like showing compassion to the victim. etc. rules are followed.
