Another term for limited-use (LUK) or single key (SUK) which is, basically, the password that joins the token with the customer’s actual card number. Without the cryptogram, the token can not be validated by the token service provider and matched to the actual card number to successfully complete a purchase.

Why pteridophytes are called cryptogams?
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.
Are bryophytes vascular?
Mosses and liverworts are lumped together as bryophytes, plants lacking true vascular tissues, and sharing a number of other primitive traits. They also lack true stems, roots, or leaves, though they have cells that perform these general functions.

What is the difference between bryophytes and pteridophytes?

Are gymnosperms Cryptogams?

Who is the father of pteridophytes?
More than 20 years ago, Edward Klekowski (1979), who can validly be called the father of modern studies on pteridophyte genetics, published a summary and synthesis of the unique features of homosporous pteridophytes.
What are the three types of pteridophytes?
The three different types of pteridophytes include:
- Ferns.
- Horsetails.
- Lycopods or Lycophytes.
What is the life cycle of pteridophytes?
The life cycle of pteridophytes is a continuous reproductive process that is dominated by the sporophyte (sexual) stage of the alternation of generations. Fern spores are catapulted into the air, and the spores develop into heart-shaped haploid gametophytes that contain both male and female sex organs.
What are the 3 types of bryophytes?
In this part of the website you’ll find descriptions of the features you can see in the three groups of bryophytes – the hornworts, liverworts and mosses. The aim is to give you a good understanding of bryophyte structure and of the similarities and differences between the three groups.
Why can’t bryophytes grow tall?
Bryophytes lack vascular tissues (xylem and phloem) so water and nutrients cannot be transported to long distances, hence they can not grow tall. They also lack true roots and stem to provide structural support for growing tall plants.
Why are bryophytes non-vascular?
In all bryophytes, the primary plants are the haploid gametophytes, with the only diploid portion being the attached sporophyte, consisting of a stalk and sporangium. Because these plants lack lignified water-conducting tissues, they can’t become as tall as most vascular plants.
