Unicellular organisms grow by ___________.
cell division.
Multicellular organism grows by ____________.
cell division
Non-living objects also grow. A dead organism _______ grow.
does not
Non-living is not the same as being dead because non-living things were never alive and therefore cannot die.
- Dead means that it was once living .
- Non-living means that it never lived.
So, when we talk about living things growth, it's increase in mass as well as number. When we say dead, it means opposite of living. Hence , dead organism neither grow by mass nor by number.
When we say non living , it's direct meaning tells that non-living grows by increase in mass by accumulation of material on the surface.
Fungi multiply and spread easily due to the millions of asexual_______ they produce.
spores
The fungi, the filamentous algae, the protonema of mosses, all easily multiply by ___________.
fragmentation
Two various types of sexual and asexual spore are produced by fungi.Asexual reproduction is by spores called ________ or __________ or ___________, and sexual reproduction is by ___________, __________ and _____________.
Asexual reproduction is by spores called conidia or sporangiospores or zoospores, and sexual reproduction is by oospores, ascospores and basidiospores.
An isolated metabolic reaction(s) outside the body of an organism, performed in a test tube is _____________
neither living nor non-living.
Isolated metabolic reactions in vitro are not living things but surely ____________.
living reactions
Does the process of metabolism take place in living beings only? If so, then what about reactions in a test tube?
Metabolism is one of the defining features of living organisms. It exclusively occur in living beings. The reactions occurring in test tube may produce energy, may produce some useful products or some wastes but metabolism refer to life sustaining chemical reactions occurring in living cells. So obviously there is no metabolism occurring in test tube as there are no living cells involved in it.
Is there a thing that is neither living nor non-living?
Scientists categorize viruses as neither living nor non-living. This is due to the fact the viruses possess the characteristic of both the living and the non-living. For instance, viruses can reproduce inside a host just like any other living organisms, but this ability to reproduce is lost when the virus is outside the host cell.
Are coacervates living or non-living?
Coacervates and microspheres appears to be living showing most of the characteristics like cell division, but lacks one of the most important charectristic that is reproduction. So it is a non living entity.
Why is an isolated metabolic reaction performed in a test tube neither living nor non-living?
For your metabolic reaction, we probably need an enzyme—notice I’m not saying a catalyst. Enzymes are products of living systems. If we isolate one and have nothing for it to work on, we simply have a protein—derived from living systems but not living.
Suppose we were to say ‘mammals’, you would, of course, think of animals with ___________
external ears and body hair (etc)
- (a) Diaphragm
- (b) Seven cervical vertebrate
- (c) Mammary glands
- (d) Gives birth to young ones
- (e) Non nucleated RBC
- (f) Pinna
- (g) Corpus callosum in brain.
- (h) Body Hair
Solanum includes species like________and_________ .
nigrum and melongena
Genera Solanum, Petunia and Datura are placed in the family _________.
Solanaceae
Plant families like Convolvulaceae, Solanaceae are included in the order ________ mainly based on the _______.
Polymoniales,floral characters
Order __________ comprising monkey, gorilla and gibbon is placed in class _______ along with order ________ that includes animals like tiger, cat and dog.
Primata,Mammalia,Carnivora
a-Hominidae,b-Dipthera,c-Anacardiaceae,d-Sapindales,e-Poaceae,f-Poales
The biggest spin off of such studies was the recognition of the sharing of similarities among living organisms both ______________.
horizontally and vertically
The relationship between species in the present day are the horizontal relationships. You can compare species horizontally by, say, looking at the skull of a human and the skull of a chimpanzee.The relationship between species today and species that have existed in the past( by their fossils) are the vertical relationships.For example, you could look at the skull of a Homo sapiens and compare it to the skull of Homo habilis exist earlier.
The earliest classifications were based on the ‘________’ of various organisms.
uses
Solanum. Lion (Panthera leo), leopard (____________) and tiger (P. tigris)
P. pardus
Find odd one out : Sapindales,Anacardiaceae,Poales
Poales
Plant species in Botanical gardens are grown for________ purposes
identification
___________ contains the actual account of habitat and distribution of plants of a given area.
Flora
