Plant Kingdom Passage-Based Questions for NEET
Q.1. Complete the given passage with appropriate words or phrases.
The gymnosperms are plants with naked seeds. In gymnosperms, (i) are not enclosed by any ovary wall. They generally possess tap roots. Roots of Pinus have fungal association in the form of (ii) , while in Cycas, small specialised roots are called (iii) roots and are associated with (iv) . In (v) , male and female strobili are present on the same tree. The megaspore mother cell undergoes (vi) to form four megaspores. One of the megaspore enclosed within megasporangium develops into (vii) gametophyte, which possess a distinct (viii) . The pollen grains are released from (ix) and is carried by air currents to ovules. The pollen tube carrying male gametes grow towards archegonia and results in fertilisation by (x) .
A.1. (i) ovules (ii) mycorrhizal (iii) coralloid (iv) N2-fixing cyanobacteria (v) Pinus (vi) meiosis (vii) female (viii) archegonia (ix) microsporangium (x) siphonogamy
Plant Kingdom Assertion and Reason Questions for NEET
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.
Q.1. Assertion: Cycas is also called living fossil.
Reason: Cycas possesses characters of both extinct pteridosperms and cycads.
A.1. (a)
Q.2. Assertion: In gymnosperms, the male and female gametophytes do not have independent existence.
Reason: They remain within the sporangia retained on the sporophyte.
A.2. (a)
Q.3. Assertion: In bryophytes, there is progressive sterilisation of sporogenous tissue as we move from lower to higher forms.
Reason: In mosses, the sporogenous tissue is present inside the capsule that includes columella.
A.3. (b)
Plant Kingdom Figure-Based Questions for NEET
Q.1. Consider the given figure and answer the following questions.
(a) What does the given figure represent? Which plant groups show this type of life cycle?
(b) Identify the haploid and diploid stages in the given life cycle.
(c) Which cell division would occur at X?
A.1. (a) Haplo-diplontic alternation of generation. Mostly bryophytes and pteridophytes show haplo-diplontic life cycle. However, Dictyota, a brown algae also shows this type of life cycle.
(b) Haploid stages – Spore, gametophyte, female and male gametes. Diploid stages – Zygote, sporophyte, spore mother cell, sporangium.
(c) Meiosis
