What plants first developed during the Sirulian period?
During the Silurian period, plants such as the first vascular plants, including ancestors of modern ferns and mosses, evolved. These plants were some of the earliest to develop vascular tissue, allowing them to transport water and nutrients throughout their structures. They played a crucial role in shaping terrestrial ecosystems during this time.
What characteristics do seed plants share?
First they share Vascular Tissue. Second they share Pollen to produce.
Does moss have vascular tissue to carry water and food?
yes, because there is xylem in water and moss needs water to survive. moss was also the first plant in water. but it was the second plant on earth. green algae was the first plant on earth. green alage was also the first plant on land.
Which plants first developed a circulatory system?
Mosses and worts are non-vascular. The ferns were the first plant species to develop a circulatory system that lets them grow larger. They have roots, leaves, stems, and trunks. With their new vascular system, the sky was the limit for plants.
What is Pteridophytes?
Pteridophytes are a group of vascular plants that reproduce via spores. They include ferns, horsetails, and club mosses. These plants have well-developed vascular tissues for conducting water and nutrients.

What is the first stage in the hemostat process?
The first stage is vascular spasm.
What is the main difference between nonvascular plants and vascular plants?
The difference between vascular and non-vacular plants is that, vascular plants have tubes that carry water up the plant/tree, non-vascular plants dont have those in which case, they need to live near water. Vascular plants are considered the "flowering plant", non-vascular plants have spores and don't need to "mate" with another plant to make a new one, they just need to get their seeds off of them the right way. Vascular plants have a system of cells that transport water through the plant, non-vascular plants do not.
