Plants are autotrophs, while animals are heterotrophs. Cell wall is present in plant cells, while it is absent in animal cells. Plants do not need to move from one place to another, while most of the animals need to move in search of food. For more answers visit to website: https://www.tiwariacademyRead more

Organisation of nucleus is the primary characteristic on which the first division of organisms is made. Based on this, organisms can be either prokaryotic or eukaryotic. For more answers visit to website: https://www.tiwariacademy.com/ncert-solutions/class-9/science/chapter-7/

The kind of cells an organism is made of is more basic characteristic of classifying organism because it gives a scientific angle to classification. Moreover, a particular dwelling place can be full of organisms of a wide variety. For more answers visit to website: https://www.tiwariacademy.com/ncerRead more

Three examples of the range of variations in life forms: - Ants, cockroaches, spiders, houseflies, etc. live in the same building. They look entirely different from each other yet all of them belong to arthropoda. - Humans, monkeys, cats and dogs lives in the same neighbourhood. They look entirely dRead more

– Ants, cockroaches, spiders, houseflies, etc. live in the same building. They look entirely different
from each other yet all of them belong to arthropoda.
– Humans, monkeys, cats and dogs lives in the same neighbourhood. They look entirely different
yet all of them belong to mammalia.
– A nearby park may show wide variety of plants; right from small grass to a giant banyan tree.
