Diversity in Living Organisms

3,323 Questions

The diversity in living organisms deals with the classification of life forms into various kingdoms and phyla. This topic covers specific traits of bacteria, animal body cavities, and structural adaptations for survival. These fundamentals are crucial for biology sections in medical entrance and state board exams.

  3. Body divisible into head and trunk

  4. Direct developement
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Tympanum is a membrane of the eardrum. It has a three chambered heart made of muscle tissues. The body of the frog is divisible into head and trunk. The head is in a triangular shape. The lungs is present in the trunk of the body.

Frog is not assiciated with direct development. It develops from a tadpole.

Frogs absorb water through their skin (1), male frogs possess vocal sacs for calling (3), and they have a bilobed tongue for catching prey (5). Hind limbs have five digits, not four, and copulatory pads are on the first digit, not the second.

Multiple choice biology organization of life comparison of prokaryotic vs eukaryotic cells prokaryotic cell and eukaryotic cell types of cell

All animals are eukaryotes and multi-cellular.

  1. True

  2. False

  3. Ambiguous

  4. Data insufficient
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Organisms are divided into five kingdoms by R.H.Whittaker. According to this classification all the prokaryotes and unicellular organisms are grouped under kingdom Monera and some in kingdom Protista.

Multiple choice biology organization of life comparison of prokaryotic vs eukaryotic cells prokaryotic cell and eukaryotic cell types of cell

The numbers of vacuoles are __________ in animals are compared to plants.

  1. More

  2. Less

  3. Same

  4. Can't define
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Plants don't have excretory system, thus possess larger vacuole to store their waste metabolites. Whereas animals have comparatively smaller vacuoles used for storage's of food materials. Thus the number of vacuoles in animal cell would be larger due to its size as compared to plants.

Multiple choice biology organization of life comparison of prokaryotic vs eukaryotic cells prokaryotic cell and eukaryotic cell types of cell

Bacteria differ from eukaryotes in absence of

  1. DNA

  2. Basic proteins

  3. Histones

  4. Both B and C
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Prokaryotic cells synthesize a set of small, usually basic proteins that bind DNA and are collectively called histone- like proteins because their biochemical properties resemble eukaryotic histones but histones are absent in Bacteria

So, the correct answer is 'Histones'

Multiple choice biology organization of life comparison of prokaryotic vs eukaryotic cells prokaryotic cell and eukaryotic cell types of cell

Cell wall is absent in

  1. Mycoplasma

  2. Gametes

  3. Animal cells

  4. All the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Cell wall is composed of cellulose and it is mostly prominent in plant cell. It provides structural frame work to the cell and provides strength and rigidity to the cell.
Mycoplasma lacks cell wall around its plasma membrane which makes it resistant towards common antibiotics such as penicillin or other beta-lactam antibiotics that target cell wall synthesis.
Gametes are the haploid cells which is lined by basal germinal epithelium.
Animal cell lacks the cell wall and starts with the plasma membrane.
So, the correct answer is option D.
Multiple choice biology organization of life comparison of prokaryotic vs eukaryotic cells prokaryotic cell and eukaryotic cell types of cell

Which of the given structures of prokaryotes, resemble in composition to that of eukaryotes?

  1. Cell wall

  2. Cell membrane

  3. Ribosomes

  4. Both (2) and (3)
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Both prokaryotic and eukaryotic cells have a cell membrane, a double layer of lipids that separates the cell interior from the outside environment. This double layer consists largely of specialized lipids called phospholipids.
Thus, the correct answer is 'Cell membrane.'
Multiple choice biology organization of life comparison of prokaryotic vs eukaryotic cells prokaryotic cell and eukaryotic cell types of cell

Statement I : All prokaryotes have a cell wall, eukaryotes do not.
Statement II : Prokaryotes have a true nucleus, eukaryotes have a primitive nucleus.

  1. Both statement I and statement II are true and statement II is the correct explanation of statement I.

  2. Both statement I and statement II are true but statement II is not the correct explanation of statement I.

  3. Statement I is true but statement II is false.

  4. Both statement I and statement II are false.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Prokaryotes generally have a tough layer which helps to maintain the strength and rigidity of the cells known as the cell wall. All the prokaryotes do not possess cell walls such as Mycoplasma. Eukaryotes like animals lack cell walls it starts with plasma membrane while plants have a cell wall.
Prokaryotes have a primitive nucleus that lacks membrane while eukaryotes have a true nucleus that has a double membrane nucleus. Thus, the correct answer is option D.
Multiple choice biology organization of life comparison of prokaryotic vs eukaryotic cells prokaryotic cell and eukaryotic cell types of cell

Prokaryotic and eukaryotic flagella differ in

  1. Type of movement and position

  2. Microtubular organisation and function

  3. Location and mode of functioning

  4. Microtubular organisation and type of movement.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Prokaryotic and eukaryotic flagella have the same function in the organism. They both are located on the cell membrane. However, they differ in their structure and dynamics. Eukaryotic flagella are microtubule-based structures. They are attached to the cell at the cell membrane by basal bodies. Prokaryotic flagella are located outside of the plasma membrane. Prokaryotic flagella show rotatory movement. Whereas eukaryotic flagella show lashing movement. The movement of prokaryotic flagella is proton-driven whereas the movement of eukaryotic flagella is ATP driven. Eukaryotic flagella show 9 + 2 microtubules arrangement.

Thus, the correct answer is option D.

Multiple choice biology biology : an introduction introduction to organization of life signs of life what is living?

The attributes of living organisms are

  1. Reproduction

  2. Self consciousness

  3. Movement

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Living organisms are blessed with the capability to reproduce and increase in number. The living cell has cellular machinery which helps in cell division. The self-consciousness is the ability to react and respond to a particular stimulus which is due to the well developed nervous system which helps to analyse the generated response. Movement is another unique potential of a living organism which is possible due to a fully developed skeletal and muscular system.

So, the correct answer is option D.

Multiple choice biology biology : an introduction introduction to organization of life signs of life what is living?

In the living things, growth

  1. Happens from inside

  2. From outside

  3. Both A and B

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

All living beings grow by the cell division and metabolic processing like respiration, nutrition etc. The living being is made up of cells hence their division happens inside the body and thus the growth happens from inside.

So the correct option is 'Happens from inside'.
