Hetereotrophic mode of nutrition for class 10th biology

2. Hetereotrophic mode of nutrition:- In this mode of nutrition organisms obtain their food from other organisms. These organisms are totaly dependent on other organisms for food. e.g Animals,Human beings, Fungi

It has following sub types

1. Holozoic nutrition:- In this mode of nutrition an organism englough food and than digest it inside the body. e.g human being , Bird

2.Saprophytic Nutrition:- In this mode of nutrition organisms obtain their food from dead and decaying organic matter. These organisms grow on dead organic matter and screate digestive enzymes on the organic matter to digest it and than absorb the digested food. e.g Fungi (Mushrooms, bread moulds)

3.Paracitic mode of nutrition:-In this mode of nutrition organism takes the digested food of other organism by living on it. E.g Ascaris, E.coli, Tap worm , liver flukes ,lice etc . The organisms showing this type of nutrition are called as Paracites and the organism on which paracite lives is called as Host.

Paracites are of two types

●Exo-paracites:-The paracites which lives outside on the body of host are called Endo-paracites. e.g Lice

●Endo-Parcites:-The paracites which lives inside the body of host are called Endo-paracites. e.g Ascaris, E.coli , liver flukes

Male reproductive system

Reproduction In Human Beings Reproduction:- It is the biological process in which organisms give offspring for the continuity of race. A complete system is concerned to perform this function called reproductive system. Here we are going to discuss sexual reproduction in Human Beings. As we human beings are diocious i.e male and female sexes are separate Male reproductive system in Human Beings. Testis:- These are the primary sex organs of males, testis produce male sex cells (sperms) as well as male sex hormone testosterone. Testis lie out side the body between the lungs in a muscular pouch called Scrotum.Scrotum maintains the temperature of testis which is below 3℃ than body temperature. Testis are two in number. Alongside the testicles are the epididymis and the vas deferens. which make up the duct system of the male reproductive organs. The vas deferens is a muscular tube that passes upward alongside the testicles and transports the sperm-...

Structure and function of Neuron

Neurons (nerve cells) are the functional units of the nervous system. A typical neuron is divided into three parts i.e Cell body or Soma,Some contains all the cell organelles like Nucleus, Mitochondria etc. Dendrites and Axon. Schwann cells of Axon are covered by Myelin Sheath. Dendrites are branched like structures on Soma. Axon terminal is also branched like structure. The signals are received from neuron by dendrites and are send to next neuron bye chemo-electrical impulses through axon. The junction between the two cells is known as Synapses.In neuron signal travels in the form of chemicals but at synapses in changes in to electrical impulses.
