Question

Why differenciating the living organisms on the basis of whether they are plants or animals cannot form the basic characteristic of classification? Give any 4 reasons justifying the given true statement.

Answer 1

1. Few organisms like Euglena behave like animals as well as plants because they have locomotion as well as photosynthetic apparatus.
2. Algae may perform photosynthesis but don't have any movement.
3. Bacteria may or may not perform photosynthesis.

Answer 2

*Researchers at McMaster University have found that plants get fiercely competitive when forced to share their pot with strangers of the same species, but they’re accommodating when potted with their siblings.When plants share their pots, they get competitive and start growing more roots, which allows them to grab water and mineral nutrients before their neighbours get them. It appears, though, that they only do this when sharing a pot with unrelated plants; when they share a pot with family they don’t increase their root growth.
Animals exhibit trait of territoriality.
*Euglena prepares food with the chloroplhyll like plants & also moves with the help of flagellum.
*Plants donot show locomotion llike animals with the exception of swimming algae & in anlimals the sponges are stationary attached to the substratum.
*mushrooms & fungi lack chlorophyll & are saprophytic
Venus fly trap, sundew plant & pitcher plant are insectivorous & there are examples of plants which are carnivorous.
*Some plants belonging to the orchid & pea families are bilaterally symmetrical; most animals including man have bilaterally symmetrical bodies with a central nerve centre.
*Plants as well as animals secrete hormones which control growth & other activities.

Answer 3

some organisms blur the line between the two

Answer 4

don't know.
