$\bullet$ Crassulacean acid metabolism also know as CAM photosynthesis is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions. Pineapple carries out CAM photosynthesis, fixing carbon dioxide at height and storing it as the acid malate and then releasing it during the day aiding photosynthesis.

Sucking roots are present in the plant
1 Betel
2 Cuscuta
3 Mangifera
4 Solanum
Explanation:
sucking roots also known as houstorial roots are found in parasitic plants. In parasitics plant adventitious roots form the stem sucking nourishment from the host plants tissue like cuscuta (dodder), cassytha and dendrophthoe are other example of sucking roots.

The CORRECT sequence of events during double fertilization in Angiosperms is
1 Triple fusion, syngamy, porogamy
2 Syngamy, triple fusion, porogamy
3 Porogamy, syngamy, triple fusion
4 Syngamy, porogamy, triple fusion
Explanation:
Double fertilization involves two sperm cell: one fertilizes the egg cell to form the zygote that process is called syngamy and other fuses with two polar nuclei to form endosperm and that process is called triple fusion. The entry of the pollen tube in the egg apparatus through micropyle (porogamy) is followed by syngamy and triple fusion. Thus, the correct sequence is porogamy, syngamy triple fusion.

In angiosperms, during development of embryo, the suspensor cells develop from
1 Oospore
2 Integument
3 Endosperm
4 Cotyledon
Explanation:
In angiosperms during development of embryo the suspensor cells develop from the oospores. During the development of the embryo the zygote increases in size and is divided by a transverse division resulting in the formation of two unequal cells. It is a fertilized female zygote which have a thick cellulose wall. The suspensor cell situated at the terminal end of the suspensor is called the hypophysis which undergoes numerous division and the cell then later on forms the initials of the radical root, protoderm and root cap.
