Double fertilization is unique to gymnosperms and monocotyledons.
Sequoia, a gymnosperm, is one of the tallest tree species.
Phaeophyceae members possess chlorophyll a, c, carotenoids and xanthophylls.
Moss is a gametophyte which consists of two stages namely, protonemal stage and leafy stage.

Pteridophyte gametophyte has a protonemal and leafy stage.
In gymnosperms, female gametophyte is free-living.
Antheridiophores and archegoniophores are present in pteridophytes.
Origin of seed habit can be traced in pteridophytes.

In angiosperms, each embryo sac has a three-celled egg apparatus one egg cell and two synergids, three antipodal cells and two polar nuclei.
All seed bearing plants i.e., gymnosperms and angiosperms follow dipontic life patterns of plants.
In gymosperms, roots in some genera have fungal association in the form of mycorrhiza (Pinus) while in some others (Cycas) small specialized roots called coralloid are associated with N2 fixing cyanobacteria.
All of the above
Phloem of both have companian cells.
Endosperm is formed before fertilization in both.
Origin of ovule and seed is similar in both.
Both have leaves, stem and roots.

Since most rhodophyta grow at great depths, the chlorophyll can only absorb light in the red area of the spectrum.
The wavelengths of light that are absorbed by chlorophyll are passed to phycoerythrin (a red pigment).
Red pigment of rhodophyta absorbs all the light waves.
The light reaching the greatest depth in water is in the blue-green region of the spectrum, is absorbed by phycoerythrin.
