Lycophytes are the most primitive vascular plants. There are some species in existence today such as the Selanginella molendorffii (spike moss). They appeared around 400 million years ago.
The divergence of ferns (monilophytes) and seed plants (spermatophytes) occurred around 380 million years ago.

What are 2 seedless vascular plants?
Ferns are the most commonly known seedless vascular plant, while there are also horsetails and club mosses. Liverworts are not seedless vascular plants -- they are actually nonvascular.
Ferns are the most diverse seedless vascular plants today with their greatest diversity found where?
Ferns are the most diverse seedless vascular plants today, and their greatest diversity is found in tropical regions, particularly in rainforests. They thrive in warm, humid environments with consistent moisture and ample shade.
What is the most primitive division of plants they have no vascular system?
Bryophytes are the most primitive division of plants that lack a vascular system. This group includes mosses, liverworts, and hornworts. They rely on diffusion to transport water and nutrients within the plant.
How are ferns different from other green plant?
Ferns are unique among green plants in that they do not reproduce through seeds, but rather through spores. They also have a distinct vascular system that allows them to transport water and nutrients throughout their leaves and stems. Additionally, ferns typically have a feathery appearance with fronds, as opposed to the flat, broad leaves seen in many other green plants.
What are two groups of seedless plants?
Ferns are the most abundant group of seedless vascular plants, with about 12,000 living species. Recent research indicates that they may be the closest relatives to the seed plants. The fossil record indicates that ferns originated during the Devonian period about 350 million years ago and became abundant and varied in form during the next 50 million years. Their apparent ancestors had no broad leaves and were established on land as much as 375 million years ago.
The most primitive seedless vascular plants are often considered whisk ferns because?
D. A and B They lack vascular tissue in their "roots" and "leaves" and they possess rhizoids.
What are 2 seedless vascular plants?
Ferns are the most commonly known seedless vascular plant, while there are also horsetails and club mosses. Liverworts are not seedless vascular plants -- they are actually nonvascular.
What falls from ferns to make a new fern?
Ferns reproduce by releasing spores, unlike most vascular plants, which usually use seeds.
Which of the divisions of vascular plants has more members?
ferns shrubs herbs vines trees

Tropical rainforests! heh I hate plato
What plants were there in velociraptors habitat?
Velociraptor lived in a desert, so most plants only lived at oases or were very sparsely scattered. Plants that may have lived there include conifers, cycads, ferns, ginkgoes, horsetails, and early angiosperms such as primitive grasses and palm trees.

Which plants are vascular?
There are too many vascular plants to count, but vascular plants are generally taller than non-vascular plants. Most plants are vascular.
Are plants vascular or nonvascular?
Both.Some plants have vascular systems, while others do not. Most plants that we commonly think of, like trees, flowers, and bushes, are vascular. Some simpler plants, like moss and ferns, are nonvascular.In plants, a vascular system is analogous to the heart, veins and arteries of an animal (which is why it's called a cardiovascular system). It is a system of "tubes" that transports water and nutrients throughout the plant. Mosses don't need vascular systems because they are not very tall, so the water doesn't have to reach very far.
