Answer 2

There is ecological CONFLICT and COOPERATION among members of POPULATION, members of COMMUNITY, or among population.

Question 3

How does the molecular traffic inside cell represents life?

Answer 3

Metabolism is the defining feature of Living organism.

Question 4

What are the some characteristic features of living organisms? that DISTINCT them from non-living organisms.

Answer 4

•Growth
•Reproduction
•Ability to sense environment
•Metabolism or Cellular Organisation
•Self replication
•Self Organisation
•Interaction
•Emergence

Question 5

Name a living organism that do not grow.

Answer 5

Every living organism grows. There is no such organism that does not grow.

Question 6

What are the two means of growth?
Or What are the TWIN CHARACTERISTICS of growth?

Answer 6

•By increase in Body Mass (not defining)
•By increase in no. of individuals

Question 7

Which chapter can be considered as application of the growth?

Answer 7

Cell Division

Question 8

How to check whether the growth has happened in in vitro culture?

Answer 8

Check whether the number or the count of cells has increased or not.

Question 9

In which type of organisms application of cell division is found?

Answer 9

•Multicellular
•Unicellular

Question 10

What is the difference between the cell division of plants and cell division of animal cells?

Answer 10

Cell division in PLANTS continues throughout their LIFESPAN, but in ANIMAL cells it continues only up to a CERTAIN AGE. Certain tissues only replace the lost cells, e.g. check cell division chapter

Question 11

There is no unicellular animal found, but is there a unicellular plant?

Answer 11

Yes, unicelluar algas

Question 12

Why the increase in body mass should not be considered as defining feature for living?

Answer 12

Non-living organisms grow by accumulation of matter on their SURFACES.

Question 13

Name a unicellular organism which cannot increase the number of individuals.

Question 14

Can growth from inside considered as defining feature?

Answer 14

Yes, the intrinsic growth can be considered as a defining feature because only living organisms grow from inside.

Question 15

Growth is characteristic feature or defining.

Answer 15

Growth is a characteristic feature but not a defining feature.

Question 16

Growth and Reproduction are Mutually EXCLUSIVE Events in…

Answer 16

HIGHER Plants and HIGHER Animals

Question 17

Define Reproduction in Multicellular Organisms?

Answer 17

A progeny is produced which has features similar to parents.

Question 18

We INVARIABLY and IMPLICITLY refer to which kind of reproduction in case the features are more or less similar to the parents in progeny.

Answer 18

Sexual

Question 19

Now tell us why the lower animals have reproduction and growth are mutually inclusive?

Answer 19

In lower organisms such as yeast and hydra, they reproduce by asexual methods of reproduction by budding, planaria possesses true regeneration.

Question 20

Now tell us why the lower plants have reproduction and growth mutually inclusive?

Answer 20

Lower plants such as PROTONEMA of mosses and FILAMENTOUS algae reproduce by FRAGMENTATION, which is asexual mode of reproduction.

Question 21

In which type of organisms, the growth and reproduction are SYNONYMOUS?

Answer 21

In single-celled unicellular organism, increase in number of cells is synonymous to growth and reproduction e.g., bacteria, unicellular algae(lower plants), and amoeba.

Question 22

Why Reproduction is All-INCLUSIVELY Non-Defining Feature? But Characteristic.

Answer 22

Mules
Sterile worker bees
Infertile Human couples
Are incapable of reproducing but are still living.
But Characteristic because non-living organism can’t reproduce or replicate.

Question 23

What are ALL organisms made up of?

Answer 23

Chemicals

Question 24

What are these chemicals called?

Answer 24

Biomolecules
Application in Organic Chemistry and Other biology chapter

Question 25

Biomolecules are classified in various CLASSES (ex. Proteins, amino acids etc.) on the basis of

Answer 25

•Sizes
1.)Small—Acid Soluble Pool with low molecular weight
2.)Big—Acid Insoluble Pool with high molecular weight
•functions
