The adult urochordates lack notochord but the larval stage of the urochordates have notochord. This is because it helps in swimming of the organism which is required only at the larval stage.

The adult stage of the tunicates is sessile and they do not swim so they do not require notochord.

tensa zangetsu [6.8K]

Habitats of the plants:

X : winter or cold mountainous habitat

Y : desert habitat

Z:  Aquatic habitat

The cone like structure of leaves help them let the snowfall.

The plant Y leaves and root morphology suggests that it is well suited for dry lands or desert as where less water is there. They store water for longer time when it rains because of the extensive root system. The spine leaves help in reduced transpiration as water scarcity is there.

The plant Z leaves morphology suggests that thin and ribbon structure leaves can help them resist the pressures of flowing water as there are air space in the leaves which provide buoyancy to the leaves.
