A group of plants or animals with similar traits of any rank is 

  1. Species

  2. Genus

  3. Order

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

Each unit or category of classification is termed as a taxon. It represents a rank. All the organism belonging to a similar taxon share similar traits. For example, the basic level of classification is species, followed by genus, family, order, class, phylum or division, in ascending order.

So, the correct option is 'Taxon'.

In flowering plants archesporium gives rise to.

  1. Wall of sporangium

  2. Both wall and sporogenous cells

  3. Wall and tapetum

  4. Tapetum and sporogenous cells
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A flower with over one thousand stamens is?

  1. Bignonia

  2. Bombax

  3. Cannabis

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

Adansonia, commonly known as the baobab tree, produces large flowers characterized by an exceptionally high number of stamens, often exceeding one thousand. This massive number of stamens helps ensure pollination by various nocturnal animals and insects. The other listed genera do not exhibit this specific extreme polyandrous trait to this extent.

Salicornia is an example of ____________.

  1. Epiphyte

  2. Halophyte

  3. Mesophyte

  4. Parasite
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Salicornia is a genus of succulent, salt-tolerant flowering plants that grow in salt marshes, mud flats, and along seashores, making them classic examples of halophytes. Halophytes are adapted to thrive in high-salinity environments by employing various physiological mechanisms to handle osmotic stress. They are neither epiphytes, parasites, nor standard mesophytes.
