NCERT solution

(1)

Identify the correct sequence of taxonomical categories?
(a) Species - Order - Phylum - Kingdom
(b) Genus - Species - Order - Kingdom
(c) Species - Genus - Order- Phylum



SOLUTION
(a) and (c) represent correct sequences of taxonomic categories as the correct hierarchical arrangement of taxonomic categories in ascending order is
Species → Genus → Family → Order → Class → Phylum → Kingdom
In sequence (b), species should have been followed by genus. Therefore, it does not represent the correct sequence.

DEFINITION

Hierarchical of classification groups
  • Carolus von Linnaeus created a hierarchical classification system using seven taxonomic categories.
  • Kingdom - Top most taxonomic category.
  • Phylum - Term used for animals while its synonym division is used for plants.
  • Class - One or more than one order makes a class.
  • Order - One or more than one similar families constitute order.
  • Family - Collection of similar genera.
  • Genus - Group of similar species.
  • Species - Group of population which is similar in form, shape and reproductive features so that fertile sibling can be produced.

01   DEFINITION Diagrammatic representation of hormones produced in Human body Diagrammatic representation of the various endocrine hormones produced by the glands and tissues in a human body. 02   DEFINITION Endocrine glands Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into the blood rather than through a duct.  The major glands of the endocrine system include the pineal gland, pituitary gland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, hypothalamus and adrenal glands. 03   DEFINITION Hormones from anterior pituitary gland Hormones from anterior pituitary gland are as follows: Growth hormones: Promote growth of whole body, particularly of the skeleton. Thyroid stimulating hormone: Stimulates thyroid to secrete thyroxine. Adrenocorticotropic hormone: Stimulate adrenal cortex. Gonadotrophic hormone: Regulates the activity of gonads (testes and ovaries).

Chapter 5 Morphology of Flowering Plants

01 DEFINITION Root Roots help to absorb water. In tap root, the secondary root emerges from the primary root. In fibrous root, the primary root and secondary root emerges from the same point. 02 DEFINITION Modifications of roots Roots are the part of the plant which is mainly used for support and anchorage of plants. Some of the roots like carrot and radish are modified to perform a special function like storage of food. The food stored in the roots is utilized during unfavorable conditions. Roots like Rhizophora, are modified for gaseous exchange. They have minute pores which help to exchange gases. Stilt roots provide mechanical support to the plant e.g., sugarcane. Climbing roots provide aerial support to the plant e.g., vanilla.  Clinging roots provide mechanical support to the plants e.g., orchids. Sucking roots helps to withdraw nutrition from other parts of the plant e.g., cuscuta. Floating roots help the aquatic plants to store air e.

Contact 8 Call-basic unit of life

01 DEFINITION Cell- Basic unit of life The cell is the basic unit of life (smallest unit of a living being). It is the structural unit of life because several cells make the structure of an entire organism (e.g. animal body is made of different cells; brain-brain/nerve cells, muscle- muscle cells) It is also the functional unit of life because several cells are responsible for proper functioning of an organism as a whole. 02 DEFINITION Contributors to the study of cell The cell is the basic structural and functional unit of life. Anton Von Leeuwenhoek first saw and described a live cell.  Robert Hooke first coined the term Cell after observing the compartments in the thin-sliced cork. Matthias Schleiden, a German botanist reported that all plants are composed of different kinds of cells which form the tissues of the plant. Theodore Schwann (1839), a British Zoologist proposed that; Cells have a thin layer (plasma membrane), Cell wall is unique
