heterosporous means that male and female organs are different. One structure produces eggs and other produces sperm. If a plant has seeds, which contains the embryo, then that clearly means sexual fertilization and a male/female gametophyte had to be involved. In short, yes. All seed plants are hetrosporous by that logic.
Not all plants do actually. Most Vascular Plants ( plants with tubes ) have seeds. Some plants have spores instead of seeds.
Yes. They are called Gymnosperms, which means ' naked seed. '
Cellulose is not a plant. It is a carbohydrate, a polymer of sugar that makes up the cell wall of all plants.
seed plants
Non-seed plants reproduce like fungi, by using spores. Examples are mosses and ferns.
Flowering Plants are Heterosporous.
Only seeds have seed coats not plants. Not all seeds have seed coats.
Conifers
Non-seed plants evolved from seed plants.
Seeds.
Flowers and reproduce by seed

Not all plants do actually. Most Vascular Plants ( plants with tubes ) have seeds. Some plants have spores instead of seeds.
In flowering plants, the megaspore becomes the female gametophyte. It is the larger meiospore produced in heterosporous plants, and is the embryonic sac of a flower.
No, as non-vascular plants do neither.
No , only seed plants produce seeds .
Yes, seed plants are vascular.
