Plants and animals are both eukaryotic organisms. Both are put into different groups on the basis of their mode of nutrition as well as their body designs. Plants are autotrophic and perform photosynthesis whereas animals are heterotrophic and get food from the outside. Plant cells have cell wail (of cellulose) whereas animal cells do not have any cell wall.
The more basic characteristic for classifying organisms is - (b) the kind of cells they are made of. It is erroneous to classify organisms on the basis of the place where they livs (such as aquatic, terrestrial, aerial, etc.) because many different kinds of organisms may live in the same habitat butRead more
The more basic characteristic for classifying organisms is – (b) the kind of cells they are made of. It is erroneous to classify organisms on the basis of the place where they livs (such as aquatic, terrestrial, aerial, etc.) because many different kinds of organisms may live in the same habitat but they do not belong to the same group. For example/ sponges, corals, whales, octopuses, starfishes, fishes (sharks), etc., live in sea but they differ with each other.
1. The living organisms vary in size from a few micrometers (e.g., microscopic bacteria) to more than 30 metres long (e.g., blue whale) and more than 100 meters tall (e.g., red wood trees of California). 2. The living organisms vary in longevity from a few days (e,g., mosquitoes) to several thousandRead more

2. The living organisms vary in longevity from a few days (e,g., mosquitoes) to several thousand years e.g. pine trees.
3. The living organisms range from colourless or transparent to brightly coloured birds and flowers.
There is vast number of living organisms in this biosphere and they have a great diversity in shape, size and form. It is practically not possible to examine and study each and every organism separately at individual level. It is therefore, advisable to study the diversity of organisms by classify tRead more

It is true that a section of people in India are still without food. Instances of hunger are prevalent despite overflowing granaries, with some rotting away and some being eaten by rats. This situation has arisen due to shortcomings in the Public Distribution System which has proved to be ineffective. The average consumption of PDS grain at the all-India level is only 1 kg per person per month. The average consumption figure is as low as less than 300 grams per person per month in the states of Bihar, Orissa and Uttar Pradesh. As a result of malpractices people prone to food insecurity do not get food grains in time. The affected persons do not get help in time due to insufficient and corrupt officials. As a result of this state of affairs, a section of the people in India are still without food. For example, the places like Kalahandi and Kashipur in Orissa, famine like conditions have been existing for many years and where some starvation deaths have also been reported. Starvation deaths are also reported in Baran district of Rajasthan, Palamau district of Jharkhand and many other remote areas during the
recent years.
