The first land plants were ___ .
- a. gnetophytes
- b. gymnosperms
- c. bryophytes
- d. lycophytes
Introduction: The plants are multicellular, photosynthetic eukaryotes on land. They are close to green algae as they have cellulosic cell walls, chloroplasts, and store starch. They have alternation of generations that is a haploid generation (gametophyte) alternates with a diploid generation (sporophyte). It is estimated that first land plants evolved about 500 million years ago. They were non-vascular plants including liverworts, mosses, and hornworts.
Explanation of Solution
Reason for the correct statement:
Liverworts, mosses, and hornworts are grouped under bryophytes. They are non-vascular, seedless. They reproduce using spores and have gametophyte dominant life cycle. These are the first land plants and are considered to be the closest link between the aquatic and land plants. They evolved from green algae.
Hence, option c. is correct.
Reasons for the incorrect statement:
Option a. is given as “gnetophytes”.
Gnetophytes are grouped under gymnosperms referred as vascular plants that evolved after non-vascular plants that is bryophytes...
