Pyrenoids contain protein besides starch.
Sexual reproduction may be isogamous, oogamous and anisogamous in green and brown algae.
Some of the members of algae also occur in association with fungi (lichen) and animals (eg, on sloth bear).
The leaves in pteridophytes are well adapted to withstand extremes of temperature, humidity and wind.

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.
only a few morphological characters.
evolutionary tendencies which are diverse.
anatomical characters which are adaptive in nature.
physiological traits alongwith morphological characters.
The predominant stage of its life cycle is the gametophyte which consists of two stages protonema and leafy stages.
Leafy stage are attached to the soil through unicellular and branched rhizoids.
Sex organs-antheridia and archegonia are produced at the apex of the leafy shoots.
All of the above
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.
