Answer:
Flowers and fruits
Explanation:
The plants which possess vascular tissues are known as the vascular plants like the pteridophytes, gymnosperms and angiosperms and the plants which do not contain the vascular tissues are known as nonvascular plants like the thallophytes and the bryophytes.
In the given features all the provided options are present in the vascular plants and absent in the non-vascular plants but flowers and fruits are the option which is found in some vascular plants especially in the plants of the angiosperm families and are absent in non-vascular plants also.
Thus, Flowers and fruits are the correct answer.

Answer:
Longitudinal waves have particle movement parallel to the direction of the energy.
Explanation:
A type of wave in which the particles in the medium move parallel to the direction of the propagation of the wave is known as a longitudinal wave. A sound wave traveling through air is an example of a longitudinal wave. Here, the particles vibrate back and forth in a direction parallel to the energy transport.
A type of wave in which the medium's particle movement is perpendicular to the direction of the propagation of the wave (or the direction of the energy transport) is known as a transverse wave. Transverse waves and longitudinal waves can travel through a solid medium. Longitudinal waves can travel through fluid mediums (liquid or gas) like air or water while transverse waves require a relatively rigid medium to transmit their energy.
Earthquakes generate both transverse and longitudinal waves that travel through the earth's solid structures. Only longitudinal waves can travel through the earth's core. An electromagnetic wave is produced by the vibration of charged particles and can transmit its energy through a vacuum. An example is light waves.
