e. Who proposed five kingdom classication?​

Answer 1

Answer:

a Categorization is the human ability and activity of recognizing shared features or similarities between the elements of the experience of the world (such as objects, events, or ideas), organizing and classifying experience by associating them to a more abstract group (that is, a category, class, or type), on the basis of their traits, features, similarities or other criteria. Categorization is considered one of the most fundamental cognitive abilities, and as such it is studied particularly by psychology and cognitive linguistics.

c Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature. Light intensity. Without enough light, a plant cannot photosynthesise very quickly - even if there is plenty of water and carbon dioxide.... Carbon dioxide concentration. ... Temperature.

d Sclereids are a reduced form of sclerenchyma cells with highly thickened, lignified cellular walls that form small bundles of durable layers of tissue in most plants. ... Sclereids are typically found in the epidermis, ground tissue, and vascular tissue. The term "sclereid" was introduced by Alexander Tschirch in 1885.

e Robert Whittaker's five-kingdom system was a standard feature of biology textbooks during the last two decades of the twentieth century.

Answer 2

Explanation:

a) Classification, in biology, the establishment of a hierarchical system of categories on the basis of presumed natural relationships among organisms. The science of biological classification is commonly called taxonomy (q.v.).

b) the difference between fungi and plantae is mentioned under... >>>1. Plants have chlorophyll and can produce their own food, fungi live off others, and they cannot produce their own food. ... The cell walls on plants are made of cellulose, while those of fungi are made of chitin.

c) Three factors can limit the rate of photosynthesis : light intensity, carbon dioxide , concentration , and temperature.

• Light intensity. Without enough light, a plant cannot photosynthesise very quickly - even if there is plenty of water and carbon dioxide. ...

• Carbon dioxide concentration. ...

• Temperature.

d) Sclereids are a reduced form of sclerenchyma cells with highly thickened, lignified cellular walls that form small bundles of durable layers of tissue in most plants. ... Sclereids are typically found in the epidermis, ground tissue, and vascular tissue. The term "sclereid" was introduced by Alexander Tschirch in 1885.

e) Robert Whittaker's proposed five kingdom of classification.
