In a given habitat we have 20 plant species and 20 animal species. Should
we call this as ‘diversity’ or ‘biodiversity’? Justify your answer.
International Code of Botanical nomenclature (ICBN) has provided a code
for classification of plants. Give hierarchy of units of classification
botanists follow while classifying plants and mention different ‘Suffixes’
used for the units.
A plant species shows several morphological variations in response to the altitudinal gradient. When grown under similar conditions of growth, the morphological variations disappear and all the variants have common morphology. What are these variants called?
Such plants variants are known as Biotypes. All the biotypes are similar genetically but are different morphologically. The difference in the morphology is due to the abiotic factors like temperature, soil quality, climate, water availability etc. The difference in the abiotic conditions is due to the altitudinal gradient. Therefore the plant species show differences in morphology due to the altitude gradient.
When these plants are grown in similar conditions , there is no difference in the abiotic factors and hence all are similar in morphology.
______ has a group of related genera with less number of similarities as compared to genus and species.
What is the difference between flora, fauna and vegetation? Eichornia crassipes is called as an exotic species while Rauvolfia serpentina is an endemic species in India. What do these terms exotic and endemic refer to?
Brinjal and potato belong to the same genus Solanum, but to two different species. What defines them as separate species?
Properties of cell organelles are not always found in the molecular constituents of cell organelles. Justify.
Some of the properties of tissues are not the constituent of its cells. Give three examples to support the statement.
What is the similarity and dissimilarity between “whole moong daal” and “broken moong daal” in terms of respiration and growth? Based on these parameters classify them into living or nonliving?
Nomenclature is governed by certain universal rules. Which one of the following is contrary to the rules of nomenclature?
The first word in biological name represents the genus name and the second is a specific epithet
The names are written in Latin and are Italicised
When written by hand, the names are to be underlined
