Fucoxanthin
Stem and leaves of bryophytes are analogous to vascular plants
...

Features of Funaria
– Protonema

– Fragmentation
Calyptra and Rhizoid are haploid
...

Star Like (Completely Cut Star Like)-Female Marchantia
Prothallus of fern is monoecious and protandrous with unicellular rhizoids

In gymnosperms, male
and female gametophytes are present within sporangia located on sporophyte
...

Male gametes are flagellated in ECTOCARPUS
...

Fucus shows oogamy and it exhibits diplontic lifecycle
...
e
...

Gymnosperms are called soft wood spermatophytes because they lack xylem fibers

...

Male and female gametophytes are independent and free-living in Sphagnum
...
Also, the dependence
of gametophyte on sporophyte also plays an important role in development of seed
habit
...

Salvinia, Selaginella and Azolla are heterosporous
...


Top-shaped multiciliate male gametes and the mature seed which bears only one
embryo with two cotyledons are characteristic features of cycads
...

Genera Plantarum written by Bentham & Hooker
In biology, phenetics, also known as taximetrics, is an attempt to classify
organisms based on overall similarity, usually in morphology or other observable
traits, regardless of their phylogeny or evolutionary relation

tips
...

Archegonium with 4-6 rows of neck and neck canal cells
...

Cormophytes are the "plants differentiated into roots, shoots and leaves, and well
adapted for life on land, comprising pteridophytes and the spermatophyta
...
