Select the correct sequence for Homo erectus.

  • erectus → Homo → Primata → Chordata → Animalia

  • Homo → erectus → Primata → Animalia → Chordata

  • Homo → erectus → Primata → Chordata → Animalia

  • erectus → Homo → Animalia → Primata → Chordata

Taxonomic hierarchy refers to

  • step-wise arrangement of all categories for classification of plants and animals

  • a group of senior taxonomists, who decide the nomenclature of plants and animals

  • a list of botanists or zoologists, who have worked on taxonomy of a species or group

  • classification of a species based on fossil record

Find out the wrong statement -

  • . Increase in mass and increase in number of individuals are twin characteristics of growth.
  • . Growth, reproduction and ability to respond are the only unique features of living organisms.
  • . a and b both
  • . Metabolism, ability to self-replicate and self-organise are the unique features of living organisms.

In------------- of higher animals and plants-------- and ------- are mutually------ events.

  • . All, cell division, replacement, dependent
  • . Majority , growth, reproduction, exclusive
  • . All, growth, cell division, dependent
  • . Majority ,cell division, replacement, exclusive

What is correct with respect to Growth?

  • . Increase in body mass is not a criterion for growth.
  • . Increase in body mass is not observed in non-living things.
  • . Increase in mass from inside is the basis of growth in living beings.
  • . Growth is considered as defining property of living beings.

Growth is not considered as a defining property of living beings because

  • . It is difficult to observe or measure.
  • . Not a single criterion for the measurement of growth.
  • . Also observed in non-living
  • . Cannot be tracked as growth is from inside

Growth is a characteristic of----------.

  • . Living systems
  • . Living organisms
  • . Non-living
  • . Both b and c

How many of the following will show the growth or increase in mass?
Mountain, Boulders, sand mound, Dead organism, plants.

  • . 3
  • . 4
  • . 1
  • . 2

Select the correct combination:

  • . Plants: limited cell division
  • . Animals: Cell division throughout life span in all type of cells.
  • . Unicellular organisms: Growth observation by microscope
  • . Living organisms: external growth

Match the following:

p. Yeast   a. regeneration 
q. Hydra   b. budding
r.  Protonema of mossesc. fragmentation

Reproduction cannot be:

  • . Asexual
  • . Characteristics of living organisms
  • . Synonymous of growth in multicellular organism
  • . A form of fragmentation

Increase in number can be-

  • . Growth
  • . Reproduction
  • . Both a and b
  • . Accumulation

Reproduction cannot be an all-inclusive defining characteristic of living organism because of

  • . Asexual reproduction
  • . Non living organisms also replicate
  • . Examples of worker bees
  • . May occur in all type of living systems instead of living organisms.

How many of the following cannot reproduce?
Infertile Humans, Worker bees, Mules, Boulders, Fungi, Protonema of mosses.

  • . 4
  • . 3
  • . 1
  • . 5

In --------- organisms, --------is synonymous with -------.

  • . Unicellular, increase in mass and increase in number
  • . Multicellular, increase in mass and increase in number
  • . Unicellular, Reproduction and growth
  • . Multicellular, Reproduction and growth

What is wrong with respect to metabolism?

  • . Chemical conversions or metabolic conversions are constantly going on.
  • . Metabolic reactions occur simultaneously.
  • . The sum total of all the chemical reaction occurring on the surface of our body is metabolism.
  • . No non-living objects exhibit metabolism.

Isolated metabolic conversions in vitro are

  • . Living things
  • . Living reactions
  • . Non- living conversions
  • . Non-living things

What is wrong with respect to Living reactions?

  • . Neither living nor non-living.
  • . Outside the body
  • . Test tube reactions
  • . Occurring in cells in the test tubes.

--------------- is the defining feature of living beings-------exception.

  • . Metabolic reactions, with
  • . Metabolism, without
  • . Isolated metabolic reactions, without
  • . Metabolism, with

The most obvious and technically complicated feature of all living organisms would be-

  • . Sensing stimuli and responding to it.
  • . Metabolism
  • . Reproduction
  • . Defence

According to all limitations, finally which is the defining feature of life forms?

  • . Metabolism
  • . Cellular organisation
  • . Reproduction

What is defining property of the living organisms?

  • . Consciousness
  • . Reproduction
  • . Growth
  • . Metabolism

Plants respond to which types of external Factors?

  • . Light, water, Temperature and Pollutants.
  • . Light, water, Temperature, Other organisms and Pollutants.

  • . Light, Temperature and Pollutants.

Photoperiod Affects-

  • . Reproduction of seasonal breeder animals only
  • . Metabolism of seasonal breeder animals
  • . Metabolism of seasonal breeders
  • . Reproduction of seasonal breeders

What is true with respect to consciousness?

  • . All organisms are aware of themselves.
  • . All organisms handle Chemicals entering their bodies.
  • . Prokaryotic organisms do not respond to environmental cues.
  • . Human beings are not self-conscious

    The only self-conscious organisms are-

  • Primates

If we define Self-consciousness as the defining property of Human beings, what can be the exception to it?

  • . Blind people
  • . Autistic child
  • . Coma Patient
  • . Heart Patient
