Round Worm: Excretory System

 Excretory System : 

Excretion is the process of discharging unwantednitrogenous waste materials from the body. The structure of the excretory system of round worm is very simple. The system consists of two-long tubes at the two sides of the body against the lateral lines. Meeting together at the other end, the two tubes open outside through the excretory pore or cloacal aperture.

Life cycle and silk cultivation

Image
  Method of silk culture:   What is sericulture? With the aim of producing silkfiber and manufacturing silken clothes the overall process of rearing of the silk worm scientifically and to collect silk fibers from their cocoon is known as sericulture. Commercially its cultivation is very profitable.   The life cycle of mulberry silk worms:  The life of an animal from zygote tosexually mature adult stage through gradual development is known as its life cycle. The stages of life cycle of animal rotate in a cycle. In the life history of all the species of silkworm in general, there are four stages which rotate in cycles e.g. ( a) egg (b) larva (c) pupa and (d) adult   Life cycle and silk cultivation:   1. Egg collection:  The male and female silk moths mate soon after emergingfrom the pupal case. The egg is fertilized in the body of the female and the zygote is formed. Immediately after that the male worm dies and the female worm starts to lay eggs. The fe...

Experiment to show that CO2 is evolved during respiration

Image
  Experiment to show that CO 2  is evolved during respiration:   Requirements:  A round bottom flask with a cork,glass tube, flower petals, mercury, caustic potash, forceps, cotton, a stand with clamp.   Procedure:  Let us put some fresh petals in a roundbottom flask, two-piece of caustic potash is introduced into the flask and then some cotton also introduced in to the neck of the flask. Then a cork having a central hole is fitted to the mouth Procedure:  A  sieve  is  filled  with  saw  dust. Four  germinating  gram  seeds  are  placed towards the bottom of the sieve. The sawdust is moistened with water. The sieve then placed a little above the soil surface by supporting from either side of the sieve. The experimental set is then kept for observation. Observation: After a day it will be seen that roots from the seeds come out through the perforation of the sieve (due to geotropism) but again they...

Growth and Development of Plant

  Growth and Development of Plant   We know seeds give rise to seedlings, from seedlings there develops a large plant. Plant produces flowers and fruits. These are all the results of growth and development of the plant. Embryo is present in the seed. Growth of embryo is the germination. So without the growth of embryo germination of seed will not take place. Without germination seedlings will not produce. Without growth of seedlings a large plant will not develop. Without development of a large tree we shall not get flowers, fruits, seeds, wood, crops, or the forest and nothing of this sorts. So growth and development of plant is essential for them so that they can again produce seed to maintain their growing by reproduction. Again the growth and development of plant is essential for all animals including human beings, because with growth and development of plant we will not get anything like - food, medicine, cloths, house building materials and a habitable environment. Growt...
