A.
Plants which manufacture their own food are termed heterotrophs.
Given below are sets of 5 terms each. Without changing the first term, rearrange the remaining four, so as to be in logical sequence as per the directions given in brackets for each. One has been done for you as an example.
Example: Pathogen, active immunity, produces antibodies, lymphocytes, antigen (defence mechanism of the body)
Answer: Pathogen antigen
lymphocytes
produces antibodies
active immunity
(ii) Interphase, Anaphase, Prophase, Telophase, Metaphase (sequential stages in karyokinesis)
Given below are sets of 5 terms each. Without changing the first term, rearrange the remaining four, so as to be in logical sequence as per the directions given in brackets for each. One has been done for you as an example.
Example: Pathogen, active immunity, produces antibodies,
lymphocytes, antigen (defence mechanism of the body)
Answer: Pathogen antigen
lymphocytes
produces antibodies
active immunity
(i) Destarched plant, iodine added, washed in water, a leaf boiled in alcohol, placed
in sunlight (testing for presence of starch)
Given below are sets of 5 terms each. Without changing the first term, rearrange the remaining four, so as to be in logical sequence as per the directions given in brackets for each. One has been done for you as an example.
Example: Pathogen, active immunity, produces antibodies,
lymphocytes, antigen (defence mechanism of the body)
Answer: Pathogen -> antigen -> lymphocytes -> produces antibodies -> active
immunity
(iii)Seminiferous tubule, penis, urethra, epididymis, vas deferens (course of passage
of sperms in man)
Given below are sets of 5 terms each. Without changing the first term, rearrange the remaining four, so as to be in logical sequence as per the directions given in brackets for each. One has been done for you as an example.
Example: Pathogen, active immunity, produces antibodies,
lymphocytes, antigen (defence mechanism of the body)
Answer: Pathogen -> antigen -> lymphocytes -> produces antibodies -> active
immunity
(iv)Pinna, cochlea, tympanum, ear ossicles, auditory canal (route through which
vibrations of sound enter the ear)
Given below are sets of 5 terms each. Without changing the first term, rearrange the remaining four, so as to be in logical sequence as per the directions given in brackets for each. One has been done for you as an example.
Example: Pathogen, active immunity, produces antibodies,
lymphocytes, antigen (defence mechanism of the body)
Answer: Pathogen -> antigen -> lymphocytes -> produces antibodies -> active
immunity
(v) Soil water, xylem, cortex, endodermis, root hair (conduction of water)Briefly explain the following terms:
(i) Destarched plant
A destarched plant is a plant which has no stored starch and from which all the starch has been removed. Its leaves will not show the presence of starch. Usually a plant is
destarched by keeping it in the dark for 24-48 hours.
