The study of varied external options of the plants is understood as a plant morphology.  The angiosperm is characterized by presence of roots, stems, leaves, flowers, and fruits.  These are the most characteristics of angiosperms.  The stem is the ascending part of the axis bearing branches, leaves, flower and fruits.  It develops from the down feather of the embryo of a germinating seed.  The stem bears nodes and internodes.  The regions of the stem wherever leaves are born are known as nodes, whereas, internodes are the parts between 2 nodes.  The main operate of the stem is spreading out branches, bearing leaves, flowers, and fruits.  Modification of stem  1. Rhizome-  Rhizome are non-inexperienced with distinct nodes and internodes.  These are brown in color.  Example- Ginger  2. Bulb- The bulb might tunicated.  A sheath of dry membranes scale leaves protected the chordate bulb.  Example- Oni...

The study of varied external options of the plants is thought as plant morphology.  The flowering plant is characterized by presence of roots, stems, leaves, flowers, and fruits.  This are the most characteristics of angiosperms.  The leaf A planar structure of a better plant, usually green and blade like, that's hooked up to a stem directly or via a stalk.  Leaves area unit the most organs of chemical action and transpiration.  A l3af consists of 3 parts- leaf base, petiole, lamina.  The leaf is hooked up with stem by leaf base which can bear 2 tiny leafs like structure is known as a plant structure.  The middledle distinguished vein termed because the mid vein.  Vein give rigidity to the leafage and act as a channel for the transport of water and minerals.  The arrangement of vein and veinlets within the plate is thought as venation.  There area unit 2 varieties of venation  1. Parallel venation  2. Reticulated venation ...

The study of varied external options of the plants is understood as the plant morphology.  The flowering plant is characterized by presence of roots, stems, leaves, flowers, and fruits.  These are the most characteristics of angiosperms.  The fruits  The fruit may be characteristic feature of the plants.  It is mature or aged ovary, developed when a fertilisation. If fruit is made while not fertilization of the ovary, it's known as a parthenocarpic fruit.  Fruit consists of seeds and seed vessel or pericarp.  Thick and fleshy seed vessel is 3 beds known as exocarp, mesocarp, and endocarp. There are of 2, varieties of seed that present in fruit.  Monocotyledon seeds  The flowering plant embryos have one cotyledon.  They have a fibrous root system.  In flowering plant flowers, the quantity of individual components of the flower is adequate or multiple of 3.  Example- Garlic, Onions, Wheat, Corn, etc.  ...

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 struc...

Animal tissues  A group of cells that have a typical origin and are similar in structure and performance is thought as tissue. Four sorts of animal tissues are found in any animal, name of them are given below. Nervous tissues  Muscular tissues  Connective tissues  Epithelial tissues  Nervous tissues   These sort of tissues are specialized to transmit message in our body.  It's responsible for the formation of the nervous system of animals.  Neuron is the structural and useful unit of nervous system.  Neurons will receive stimuli from outside or within the body, and it additionally conducts the received or self generated impulses throughout the body.  Neurons don, 't divide as cell organ centriol isn, 't present in them, however, they need the facility of regeneration.  All neuron have 3 mainparts.  Cyton, soma of cell body  It is the most portion in an exceedingly nerve cell with a distinguished nucleus and di...

Concept of species  In the system of classification the species constitutes the tiny and enormous unit of taxonomy.  Phytologist gave the standard thought of species within the book Sistema Nature. It's been diversely outlined by totally different scientists.  In line with John Ray all members made from similar oldsters are unbroken within the same species.  Mayr gave the thought of biological species as interbreeding group of organisms.  Phytologist delineate that animals with similar structural and morphological similitude from an equivalent species.  It's additionally called 'Morphological Concept.” Genetic species thought was given by Losty(1918)....

Taxonomy and systematics The study of identification and relationships among living organisms is termed Taxonomy.  The term taxonomy was first utilized by Linnaeus.  The branch of biology coping with identification, terminology and classification of organisms is termed taxonomy.  The term taxonomy was initial coined by A.P. de Candolle.  Systematics is the scientific study of the diversity of organisms.  Taxonomy is the oldest and most elementary branch of biology.  A new species being known each day and their classification and characters area unit studied with the assistance of taxonomy.  Additionally to the current, employment of scanning, nega...

Zoological parks and Zoos     Zoological parks are the guarded areas where animals are provided with conditions as they were living in their natural habitats. The parks also help to know about wild animals , their behavior and food habits. The Zoological parks and zoos have also some scientific purpose. They breed the animals which are facing a threat in their natural habitat or about to becone extinct. In National Parks, Sanctuaries, Zoological Parks and Biospheres reserves wild life can flourish in its natural surroundings. There parks and reserves are the areas in which all commercial exploitation is prohibited and their flora and fauna are well protected. There are tw...
