Question

Tomato seeds never show vivipary in their pulp due to
a) Ferulic acid in fruits
b) Presence of excess salts
c) Presence of ABA
a) Absence of oxygen

Answer 1

Hint: We have to know that Arrhenius is one of the concepts for acid and bases. Swedish chemist Arrhenius is the world's first chemist to talk about acid and bases. Depending on his concept and limitations later so many concepts are developed. Even Arrhenius is the birthplace of the concept of acids and bases. Followed by Arrhenius chemist the concept of acids and bases discuss Bronsted and Lowry in the world.
According to the Arrhenius concept one substance said to acid means, acid is nothing but a substance that dissociates to give hydrogen ion when decomposed in the water.
Examples of Arrhenius acids are hydrochloric acid (\[{\text{HCl}}\]), sulphuric acid (\[{{\text{H}}_{\text{2}}}{\text{S}}{{\text{O}}_{\text{4}}}\]), nitric acid (\[{\text{HN}}{{\text{O}}_{\text{3}}}\]) etc,.
According to Arrhenius concept one substance said to base means, bases is nothing but a substance that dissociates to give hydroxyl ion when decomposed in water.
Examples of Arrhenius bases are sodium hydroxide (\[{\text{NaOH}}\]), calcium hydroxide (\[{\text{Ca(OH}}{{\text{)}}_{\text{2}}}\]) etc,.

Complete answer:
We need to know that the seed germination requires three conditions: oxygen, water and temperature.
The given data is
Tomato seeds never show vivipary in their pulp due to Ferulic acid in fruits.
According to the above discussion, we conclude tomato seeds never show vivipary in their pulp due to Ferulic acid in fruits.
Hence, option A is the correct answer. Because tomato seeds never show vivipary in their pulp due to Ferulic acid in fruits.
Option B is not the correct answer. Because tomato seeds never show vivipary in their pulp due to presence of excess salts
Option C is not the correct answer. Because tomato seeds never show vivipary in their pulp due to presence of ABA
Option D is not the correct answer. Because tomato seeds never show vivipary in their pulp due to absence of oxygen

So, the correct answer is “Option A”.

Note:
In general, pH values of all acids are in between \[{\text{0}}{\text{.9}}\]-\[6.9\] and all the bases are in between \[7.1 - 14.0\]. But, Arrhenius theory has some limitations. One of the main limitations is not being able to explain the behaviour of acids and bases in non-aqueous solvents such as acetone etc,. It is not able to explain the acid which doesn't contain hydrogen and bases don’t contain hydroxyl ion in the formula. Ammonia is a well known base that is not accepted as base in Arrhenius base. These limitations are recovered by further coming theories like the Bronsted and Lowry concept of acids and bases.
