 Some of the outer cortical cells in the chloroplast hypodermis

 Hypodermis: It forms the outer region of the cortex.  The hypodermis is located immediately below the epidermis.  It is 3 The hypodermis is formed from the collechyma.  Collenicum in the stem of sunflower is lamellar in nature.  This keeps the thickening on the tangential walls.  Collenchyma is angular in Castor (Ricinus cummunis) and lean in Cucurbita.  Collenchyma cells connect small intercellular spaces.  They, often, contain few chloroplasts.

 Collenchymatous hypodermis has a high refractive index.  The hypodermis is absent or dilated under the stomata.  layered in thickness.  Functions: (i) It provides flexibility to young stem as well as provides mechanical strength.  (iv) Cells of Collenchymatous hypodermis as store of food.

 Common Cortex: This is the multilayered parenchymatous region that lies between the hypodermis and the endodermis.  The cells are thin walled.  They are oval or in sunflower but polygonal in castor.  Intercellular spaces are present.  Some of the outer cortical cells contain chloroplasts.  They participate in photosynthesis.

 All the cells of the cortex store food items.  places in the cortex.  Sunflower stems have oil tubes.  The oil is secreted by a peripheral layer of (3).

 glandular cells.  Instead of oil ducts, the cortex plant can anatum has resin ducts, latex vessels and even large air cavities.  Functions: (i) Storage of food (ii) Manufacture of food in the outdoor area where chloroplasts are present, (iii) Production of materials like oil and latex.  Endodermis: This is the innermost layer of the cortex.  Cells are oval or barrel-shaped, casparian strips are absent.  Cells contain abundant starch grains.  Because of this, the endodermis of the dicot stem is also called the starch sheath.  It is wavy in outline.

 Child psychology is a theoretical and applied science

 Psychology is an independent branch of psychology.  Child psychology is a biological social science.  Child psychology is a natural science.  Child psychology is a theoretical and applied science.  The above forms of child psychology are discussed in detail below: Child psychology is an independent branch of psychology.

 Psychology studies human behavior.  Childhood is one of the most important stages in the life of a human being.  This stage has some special features.  Hence it needs to be studied independently and in detail.

 Whereas the principles of psychology were applied to explain child behaviour.  Like in the olden days, it was often said that if a child doesn't study, to motivate him to study, if he doesn't study, who will give you a bride?  The study of the independent branch of child psychology began when psychologists realized this truth.

 Child psychology is a biological social science.  Child psychology studies the living entity.  Growth and development take place according to the laws of biology.  So child psychology is a biological science but the development of a child is not just according to the laws of biology.  The child lives in a social environment right from birth.
