Consider the following statements.
a. In climacteric fruits, ethylene stimulates its own production.
b. Gibberellin present in a healthy stem causes some of the new cells to differentiate as phloem.
c. Loss of turgor in leaves stimulates the production of abscises acid.
Which of the statements given are correct?

  1. $1$ and $2$ only
  2. $2$ and $3$ only
  3. $1$ and $3$ only
  4. $1, 2$ and $3$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Statement a is correct because climacteric fruits exhibit a surge in respiration accompanied by autocatalytic ethylene production. Statement c is also correct because water stress and loss of turgor in leaves trigger the synthesis and accumulation of abscisic acid to close stomata. Statement b is incorrect because gibberellins do not cause cells to differentiate specifically into phloem.

Which one of the following systems of plant classification is not phylogenetic?

  1. Bentham and Hooker's system

  2. Engler and Prantl's system

  3. Hutchinson's system

  4. Takhtajan's system
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Bentham and Hooker's system of classification is based on morphological characters and is considered a natural system, not a phylogenetic one. Phylogenetic systems aim to reflect evolutionary relationships, which the others listed do.

Which one of the following clusters of families is identified due to the presence of the zygomorphic flowers and bicarpellary gynoecium's?

  1. Cuscutaceae, solanaceae, Verbenaceae

  2. Malvaceae, Tiliaceae, Cucurbitaceae

  3. Boraginaceae, Convolvulaceae, Solariaceae

  4. Acanthaceae, Fumariaceae, Lamiaceae
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Acanthaceae, Fumariaceae, and Lamiaceae all consistently display zygomorphic (bilaterally symmetrical) flowers with bicarpellary (two-carpel) gynoecium. Other options contain families with actinomorphic flowers or different gynoecium arrangements.

The system of classification of plants proposed by these two botanists is claimed to be a natural system.

  1. Engler and Prantl

  2. Bentham and Hooker

  3. Aristotle and Theophrastus

  4. Darwin and Wallace
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

George Bentham and Joseph Dalton Hooker are the British botanists. They proposed the classification system based on the natural system. This system includes the characters of the plants which exist in the natural conditions. The plants are classified based on their relative affinities.

Thus, the correct answer is option B.

In some flowering plants, the requirement of long day length or low temperature treatment for flowering can be effectively substituted by _______________.

  1. Morphactins

  2. Coumarins
  3. $2, 4$-D

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

Gibberellins are plant hormones that can successfully substitute for long-day photoperiod requirements or low-temperature cold treatments (vernalization) to induce flowering in various plant species. They help overcome these environmental triggers artificially. Other compounds like 2,4-D are synthetic auxins used mainly as herbicides.

Match List-I with List-II and select the correct answer.

List-I List-II
a. Aborescent lycopod $1$. Rafflesia
b. Largest flower $2$. Lepidodendron
c. Largest ovule $3$. Cycas
d. Tallest tree $4$. Sequoia
  1. A-$1$, B-$2$, C-$4$, D-$3$
  2. A-$1$, B-$2$, C-$3$, D-$4$
  3. A-$2$, B-$1$, C-$4$, D-$3$
  4. A-$2$, B-$1$, C-$3$, D-$4$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Aborescent lycopods are represented by fossil plants like Lepidodendron (a-2). The largest flower is Rafflesia arnoldii (b-1). The largest ovule is found in Cycas (c-3). The tallest tree is the redwood, Sequoia (d-4). Matching these gives A-2, B-1, C-3, and D-4.
