yes some plants grow from bulbs
Not all plants do actually. Most Vascular Plants ( plants with tubes ) have seeds. Some plants have spores instead of seeds.
No, not all plants start from seeds. Some plants, like ferns and mosses, reproduce through spores or vegetative propagation where new plants grow from stems, roots, or leaves of the parent plant. Additionally, some plants can be propagated through cuttings or grafting rather than seeds.
Nearly all vegetable plants produce seeds. If your speaking of the parts of the plants that we eat as "vegetables," then none; only fruits have seeds. Of course cucumbers, peppers and many others are fruit.
Their seeds can, on the wind like a dandelion seed.
Because some reason
Moss has no flower or seed.
No, not all seed plants have sperm carried by wind-borne pollen. Some seed plants rely on other means of pollination, such as animals like insects or birds, to transport pollen.
Spore producing organisms are what form part of the life cycles of many bacteria, plants, algae, fungi and some protozoa. All plants will reproduce by either seed or spores, essentially.
Seedless plants belong to lower ladder of evolutionar sequence. These are called cryptogames (without seeds) and seed bearing plants are called Phanerogames. In cryptogames propagation takes place through spores and gametophytic stage is independent. In phanerogames propagation is through seeds and gametophytes are dependent on sporophytes.
Some flowers have the sepals act just like petals. They call these tepals. In other plants the sepal falls off after the flower opens. But some plants have the sepals become part of the seed pod or fruit.
Not necessarily. Angiosperms are a type of seed plant that produce flowers and fruit. Seed plants include both angiosperms (flowering plants) and gymnosperms (non-flowering plants like conifers). Some gymnosperms, like redwoods, can be larger than many angiosperms.
