1) cryptogams and phanerogams
2) algae and fungi
3) gymnosperms and angiosperms

Answer 1

$<b><I>$
1) difference between cryptogams and phanaerograms :


CRYPTOGRAMS:
1) it contains seedless plants
2) it includes both vascular and nonvascular plants
3) an external water is required for fertilization

PHANAEROGRAMS:
1) it contains plants with seeds
2) it includes only vascular plants
3) an external water is not required for fertilization


2) difference between algae and fungi :

ALGAE:
1) they contains photosynthetic pigments
2) Algae are autotrophic
3) most of the algae are aquatic in Habitat
4) the cell wall is made up of cellulose
5) algae contain starch as stored food material

FUNGI:
1) photosynthetic pigments are absent in them
2) fungi are heterotrophic
3) most of the fungi are Terrestrial in Habitat
4) the cell wall is made up of chitin
5) fungi contains glycogen and oil as the Stored food material


3) difference between gymnosperm and angiosperms:



GYMNOSPERMS:
1) sporophylls are aggregated to form cones
2) the seeds are naked
3) the microspores and megaspores are produced by male and female cones
4) vascular tissue such as xylem lacks visual and phloem lacks companion cells
5) the ovules or not contained within an ovary
6) endosperms cells are haploid


ANGIOSPERMS:
1) sporophyll are aggregated to Forum flowers
2) the seeds are included by a fruit wall
3) microspores and megaspores are produced in the same or two different types of flowers
4) vascular tissues such as xylem contains vessels and phloem contains companion cells
5) the ovules are enclosed within an ovary
6) endosperm cells are triploid
