Roots

The study of assorted external options of the plants is understood as plant morphology. 
The angiosperms  is characterized by presence of roots, stems, leaves, flowers, and fruits. 
These are the most important characteristics of angiosperms. 
Root
The root is underground a part of the plant and developed from elongation of raddicle. 
There are four main functions of the foundation system 
1. The absorption of water and minerals from the soil. 
2. Providing a correct anchorage to the plant elements. 
3. Storage of reserve food material. 
4. Synthesis of plant growth regulators.
 There area unit in the main three kinds of roots. 
1. Tap root- It originates from radicle. 
Example- herbaceous plant, turnip, and carrots. 
2. Fibrous root- It originates from the bottom of the state. 
Example- wheat and paddy. 
3. Adventitious root- It originates from the part of a plants aside from bodily structure. 
Example- Ficus bengalensis (proper roots), maize (stilt roots). 
The apex of the foundation is roofed by a thimble- like structure referred to as plant organ, it protects the tender apex of the foundation whereas, creating approach through soil. 
Above the foundation cap region of meristematic activity, having little cells with dense protoplasm. 
The half on top of the region of meristematic activity is the region of elongation wherever cells bear elongation and enlargement to extend the length of the foundation. 
Region of maturation contains root hairs that facilitate within the absorption of water and minerals. 
Modification of roots 
 Roots are changed for storage, organic process, aeration and support.
 The taproot of carrot, turnip and adventitious roots of sweet potato gets swollen to store food. 
Proper root of a banyan and stilt root of maize and sugarcane have supporting roots coming out from the lower node of the stems. 
In Rhizosphere, pneumatophores area unit gift that facilitate to induce atomic number 8 for respiration as it grows in slough areas.

Function of the hormones of adenohypophysis

Function of hormones of  adenohypophysis   Adenohypophysis is the real glandular part of the pituitary gland. The cells adenohypophysis secreted several hormones.  The hormones of adenohypophysis are 1. Somatotrophic hormone(STH): Growth hormone is secreted by the acidophill cells of the adenohypophysis.  It is polypeptide in nature consisting of large branches.  The molecular weight in human beings is 21500. The hormone regulates the growth of the body is thus it is necessarily concerned with the growth of skeleton, growth of muscle and growth of other organs.  Function - It stimulates the growth of skeleton in general by promoting ossification.  Hyper activity of gland in the young increases the growth of skeleton and this condition is known as gigantism.  Hypofunction of gland retrads skeletal growth and produce dwarfism.  The hormones promotes protein anabolism.  The hormone elevates the blood glucose level by stimulating glycog...

Class 6th science chapter 2 note- Components of food

Class 6th science chapter 2 note Components of food In this chapter- What is nutrient?    Carbohydrates   Fats    Proteins    Vitamins     Minerals  Roughage and water Balanced diet  Deficiency disease What is nutrients? Every days is made up of one or more ingredients.  The ingredients are the edible part of plants or animals which contains some compounds which are needed by our body called nutrients.  The major nutrients of our food are carbohydrates, fats, proteins, vitamins and minerals.  Roughage and water are also needed by our body.  Not all the food materials that we eat have the same nutrients. Carbohydrates   There are many type of carbohydrate.  The main carbohydrates which are found in our food and in the form of starch and sugar.   It gives us energy to work so it is called energy giving food.  The food like rice, wheat, potato, sugar, sweet potato are rich in carbohydrates....

Earthworms

Kingdom: Animalia Phylum: Annelida Class: Oligochaeta Order: Opisthopora Genus: Pheretima Species: posthuma Morphology   The term morphology deals with the study of the forms and therefore, the external structures of any living organism which has the dimensions, form, and structure.  There are 3 main sorts of morphology. Cellular morphology  Tissue morphology  Organ morphology  Animal morphology is healthier explained with the samples of earthworms.  Earthworm morphology  Earthworm may be a terrestrial invertebrate that is brownness in color that lives in the higher layer of dampish soil.  For example- Pheretima and Lumbricus.  Body form They have long cylindrical body divided into segments known as meta meres.  The ventral surface contains sex organ pore and dorsal surface contains middle dorsal line.  The first body phase {is known as|is named|is termed} peristpmium that contain mouth and fourteen — sixteen segments Greek dei...
