Diversity in Living Organisms

Charles Darwin in 1859 proposed the idea of evolution in the book, 'The Origin of Species'.

Species is a group of all organisms that are similar enough to breed and perpetuate.

This is not a basic feature that is considered while classifying all organisms into a hierarchical classification. Many organisms may not have any similarities except common habitat. Thus, this is the correct answer choice.

This is the correct answer. Unicellular algae have membrane bound nucleus and organelles. They come under Kingdom Protista.

Some organisms in Kingdom Monera have a cell wall and some do not have a cell wall. Thus, this is the correct answer.

Advanced organisms have acquired their particular body designs relatively recently. Primitive organisms have comparatively simpler body design. Advanced organisms are the same as complex organisms. This is the correct answer, as all statements are correct.

Fungi are saprophytes or parasites. Fungi have membrane bound nucleus. Fungi have cell walls made of chitin. This is the correct answer, as all the statements are correct.

This is the correct answer, as all statements are correct about Kingdom Protista.

Marchantia is an example of Bryophyta.

Thalophyta does not have a differentiated body. It has the simplest organisation.

Moss is a radially symmetrical leafy Bryophyte. 

Rhizoids develop as true roots are absent in Bryophytes. They do not have specialised conducting tissue.

This is the correct matching.
Kingdom Monera - Bacteria and cynobacteria
Kingdom Protista - Unicellular organisms
Kingdom Plantae - All photosynthetic green plants
Kingdom Fungi - Lack chlorophyll and obtain food through absorption
Kingdom Animalia - It is a kingdom of multicellular consumers

This statement is false, hence this option is correct. Plants have cell walls as outer most covering. Animal cells do not have cell walls.

Eichler (1883) suggested that the plant kingdom should be divided into two subkingdoms: Subkingdom Cryptogamae Subkingdom Phanerogamae. Thus, this is the correct answer.

This is the correct matching. Protista are unicellular eukaryotes, fungi and plantae are eukaryotes with cell wall. Animalia are eukaryotes without cell wall.

This is the correct answer. The plants of the group gymnosperm bear naked seeds and are usually perennial, evergreen and woody. Examples are pine and deodar.

This statement is wrong, hence this option is the correct answer. Alga does not have xylem vessels. 

Bryophytes are called as the amphibians of the plant kingdom because they live in damp areas. Their bodies are devoid of vascular tissues, roots, cuticle, etc. Therefore, they live in moist habitats in order to obtain water directly or through rhizoids and prevent desiccation.

This is the correct answer, as both statements are true.

This is the correct answer, as all the statements are true.

This is the correct answer. Sexes are separate in Nematodes.

This is the correct answer, as all statements are correct.

No, this statement is incorrect. They do not have kidney type organs for excretion.

This is the correct answer.  Porifera have pores called ostia over the body with a single large opening called osculum on top. Animals of these phylum are known as sponges.

Flatworms belong to the Phylum Platyhelminthes. This is the correct answer.

Protochordates are marine animals. They are a Phylum not a class of the Phylum of Vertebrata.

The body cavity that is not lined by mesodermal layers and the space is filled by large vacuolated cells is called pseudocoelom.

No, the amphibians have three chambered heart.

Linnaeus gave a system in which an organism is given two names. The first part is the generic name and the second part is the specific name.

This is incorrect. The binomial nomenclature states that the generic name comes first and then the specific name follows.

This is the correct answer, as all  are correct statements about chordates. These animals have a true vertebral column and internal skeleton, allowing a completely different distribution of muscle attachment points to be used for movement. Vertebrates are bilaterally symmetrical, triploblastic, coelomic and segmented with complex differentiation of body tissues and organs.

This is the correct matching. Honey bee belongs to the Phylum Arthropoda, Snail belongs to Phylum Mollusca, Star fish belongs to Phylum Echinodermata, and Earthworm belongs to Phylum Annelida.

This  is the correct answer, as this statement is incorrect. Aves have modified forelimbs for flight but they have a four chambered heart and are warm blooded.

This is incorrect, hence the correct option. They do not need water to lay eggs.
