What is the major difference between lycophytes and ferns?
Lycophytes, also known as the ‘fern allies’, are a group of roughly 1250 primitive plant species. They similar to ferns but have unique leaves called ‘microphylls’ which have only a single vein. Fern fronds are the leaves of ferns.
What is the difference between lycophytes and monilophytes?
Lycophytes have proto-steles. Very basic stele of vascular tissue with no pith. In monilophytes, the gametophyte dies off once the sporophyte is firmly established and reaches a large enough size.
What makes lycophytes different?
The distinguishing features of the lycophytes are the arrangement of their vascular tissues and their leaves—microphylls with only a single vascular strand. The sporangia on the modern plants are kidney-shaped, like those of the ancestral forms, and borne on sporophylls clustered in strobili.
Are ferns and lycophytes the same?
The lycophytes and ferns were recognized as distinct groups, but still classified together as Pteridophyta in the mid-1800s (Moran 2004), when botanists discovered that all members of these former “ferns and fern allies” share a feature of their life cycle that is unique among land plants: the two generations, the …
What classification are lycophytes?
lycophyte, (class Lycopodiopsida), class of spore-bearing vascular plants comprising more than 1,200 extant species. Three lycophyte orders are recognized: the club mosses (Lycopodiales), the quillworts and their allies (Isoetales), and the spike mosses (Selaginellales).
What is an example of a lycophytes?
Which two of the following are differences between megaphylls and microphylls quizlet?
Microphylls have a single-vein and no leaf gap. Megaphylls have branching veins and has a leaf gap.
What are pteridophytes also called?
A pteridophyte is a vascular plant (with xylem and phloem) that disperses spores. Because pteridophytes produce neither flowers nor seeds, they are sometimes referred to as “cryptogams”, meaning that their means of reproduction is hidden.
What is the main difference between Microphylls and Megaphylls?
Microphylls are defined as leaves of small size, with simple venation (one vein) and associated with steles that lack leaf gaps (protosteles). By contrast, megaphylls are defined as leaves of generally larger size, with complex venation and associated with leaf gaps in the stele .
Which two of the following are differences between megaphylls and Microphylls?
The main difference between microphylls and megaphylls is that microphylls are leaves having a single, unbranched vein, whereas megaphylls are leaves with multiple veins. Furthermore, in microphylls, the single vein originates from the protostele without having a leaf gap while megaphylls contain leaf gaps.
What is the main difference between microphylls and megaphylls?
Which two of the following are differences between megaphylls and microphylls?
What is the difference between bryophytes pteridophytes and gymnosperms?
The key difference between these three groups is the habitat where they are grown. Bryophytes are adapted to grow in amphibious environments; Pteridophytes are adapted to terrestrial environments which are a moist and shady while, Gymnosperms are fully adapted to terrestrial environments.
What are the characteristics of pteridophytes?
Pteridophytes are vascular plants. The plant body is leafy or thalloid. The plant body is differentiated into roots, stem and leaves. No vascular tissues.
What is the difference between ferns and Lycopodiopsida and pteridophytes?
Lycopodiopsida (lycophytes) and Polypodiopsida (ferns) are the two subdivisions of pteridophyata. Lycophytes consist of clubmosses, spikemosses, and quillworts. Ferns consist of horsetails, whisk ferns, grape ferns, marattioid ferns and leptosporangiate ferns.
What are the characteristics of lycophytes?
They are primitive plants and lack seeds, wood, fruit and flowers. As with the ferns, lycophytes produce spores for reproduction and are both wind-pollinated and dispersed. The phylum lycophyta is believed to be the oldest remaining group of all the vascular plants and are thought to have evolved more than 400 million years ago.
Why are pteridophytes called tracheophytes?
Pteridophytes are known as tracheophytes because they consist of specialized tissues for the conduction of water and nutrients. These specialized tissues are known as xylem and phloem. Where are pteridophytes found? Pteridophytes are found in moist, shady and damp places. They are found in crevices of rocks, bogs and swamps, and tropical trees.
