<u>Gymnosperms and Angiosperms-</u>
Gymnosperms and angiosperms evolved seeds and pollen grains allowing them to live and reproduce in drier habitats than bryophytes and seedless vascular plants.
<u>Properties of gymnosperms and angiosperms-</u>
Gymnosperms are plants which bear seeds without fruits or without any outer coverings. These plants also do not produce flowers. Most plants under this group have needle-shaped leaves. This is an adaptation as these plants grow in colder conditions. Gymnosperms. These plants produce pollen without bearing flowers. Angiosperms are found in almost all climatic conditions. These plants bear flowers and produce seeds that are enclosed inside a fruit or inside an ovary. The seeds of angiosperms have a single cotyledon.

Psuedo  functions mostly absorption and filteration processes. 
 
<h3>What is the advantage of psuedostratified epithelium? </h3>
The lungs are shielded from these irritants by the existence of pseudostratified columnar epithelium in the upper respiratory tract, which is made up of the nose, trachea, and bronchi. To capture particles and stop them from moving farther down the respiratory passages, the epithelium's goblet cells release mucus. 
The psuedostratified has too many layers and it is made up of columnar epithelial tissue.
