Which one of the following pairs is wrongly matched while the remaining three are correct
1 Agave - Bulbils
2 Penicillium - Conidia
3 Water hyacinth - Runner
4 Bryophyllum - Leaf buds
Explanation:
C Water hyacinth is a free-floating perennial plant. The dark green leave blades are circular and are attached to the petiole. They have a thick and branched fibrous root system and modified stem called as offsets. They grow horizontally outward and downward from plants and they show vegetative propagation. - Bryophyllum produces vegetative buds on leaves. - Agave has bulbils on their flower stalks. - Penicillium produced asexually through conidia and due to presence of chain of conidia, Penicillium also called as painter's brush.

Select the incorrect statement out of the following.
1 Assimilatory roots capable of photosynthesis are present in Tinospora and Trapa.
2 Haustoria of Cuscuta make connections with both xylem and phoem tissues of host.
3 Reproductive roots of Ipomoea batata help in vegetative propagation.
4 Epiphytic roots of Vanda possess well developed root caps and root hair.
Explanation:
(d) Aerial or epiphyte roots lang down in air, they do not posesses root caps and root hair.

The primary roots and its branches constitute the
1 fibrous root system.
2 tap root system.
3 adventitious root system.
4 all of the above
Explanation:
(b) Tap root or primary roots develop from the radicle. It forms lateral branches or secondary roots which are further branched to form tertiary roots. This type of root system is seen in the mustard plant.

Which of the following plant parts elongates directly and leads to the formation of primary roots?
1 bud
2 radicle
3 plumule
4 root hair
Explanation:
(b) The direct elongation of the radicle leads to the formation of primary roots which grows inside the soil. The radicle is the first part of a seedling (a growing plant embryo) to emerge from the seed during the process of germination. The radicle is the embryonic root of the plant, and grows downward in the soil (the shoot emerges from the plumule).
