Linnaeus Classification System Quiz

Questions and Answers

What were the primary Kingdoms recognized by Linnaeus based on?

Structure and functional characteristics

According to Linnaeus, what were the key structural and functional characteristics used to differentiate between the plantae and the animalia kingdoms?

The key characteristics used by Linnaeus to differentiate between the plantae and the animalia kingdoms included low motion, response to external stimuli, mode of nutrition, conductile and contractile system, and presence of a cell wall.

What were the primary Kingdoms recognized by Linnaeus and what were the distinguishing characteristics of each?

The primary Kingdoms recognized by Linnaeus were plantae and animalia. Organisms classified under plantae possessed a cell wall, did not respond to external stimuli, did not move freely, did not eat food, and lacked conductile and contractile systems. Organisms classified as animalia moved freely, responded to external stimuli, consumed holo phaged food, possessed conductile and contractile systems, and lacked a cell wall.

Study Notes

Linnaeus' Taxonomy

The primary Kingdoms recognized by Linnaeus were Plantae and Animalia.

Characteristics of Plantae

Linnaeus classified organisms as plants if they were non-motile, meaning they were stationary and did not move.
Plants were also characterized by their ability to photosynthesize and produce their own food.
Linnaeus believed that plants obtained their nourishment from soil and air.

Characteristics of Animalia

According to Linnaeus, animals were organisms that were motile, meaning they could move.
Animals were characterized by their inability to photosynthesize and produce their own food.
Linnaeus believed that animals obtained their nourishment by consuming other organisms.

Differentiation between Animalia and Plantae

Linnaeus differentiated between animals and plants based on their structural and functional characteristics, such as motility and the ability to photosynthesize.
He believed that these characteristics were the key distinguishing features between the two kingdoms.
