Passage Based Question
- Complete the given passage with appropriate words or
phrases.
Muscles are made up of highly specialised thin and elongated
cells called (i). Muscular tissues are derived from (ii) layer
of embryonic germ cells. Muscular cells are also called (iii)
or (iv). These develop from (v). Each muscle fibre consists
of fine fibrils, present in cytoplasm known as (vi) and the
membrane of each fibre is known as (vii). A muscle consists
of many muscle fibres arranged in bundles called (viii) which
is surrounded by a connective tissue sheath (ix). Each muscle
fibre is surrounded by this connective tissue sheath (x). The
connective tissue that covers the whole muscle is called (xi).
Assertion & Reason
In each of the following questions, a statement of Assertion (A)
is given and a corresponding statement of Reason (R) is given
just below it. Of the statements, mark the correct answer as:
(a) if both A and R are true and R is the correct explanation of A
(b) if both A and R are true but R is not the correct explanation of A
(c) if A is true but R is false
(d) if both A and R are false.
- Assertion : Endocrine glands do not have ducts.
Reason : Endocrine glands secrete saliva and mucus.
- Assertion : Calcium is necessary for the contraction of
muscles.
Reason : In presence of calcium ions and ATP, actomyosin
is formed.
- Assertion : Blood can prevent its own excessive loss.
Reason : Thrombocytes release platelet factors such as
thromboplastin.
- Assertion : Red bone marrow is present at the
epiphyses.
Reason : Red bone marrow is gradually replaced by
yellow bone marrow.
- Assertion : Ciliated epithelium helps in the movement
of secretions from glands, urine and semen.
Reason : Cells of ciliated epithelium are unequal in size
and only long cells have cilia at their surface.
