Which of the 4 main groups of plants does not produce seeds?

The first group of land plants are the mosses and their allies, the liverworts and hornworts. Together, they are called the bryophytes. They are land plants, but do not have seeds or flowers.

Which is a seedless plant?

A plant that does not produce seeds. Ferns, horsetails, and all the bryophytes are seedless plants.

What are the three groups of non-seed plants?

Seedless nonvascular plants are small. The dominant stage of the life cycle is the gametophyte. Without a vascular system and roots, they absorb water and nutrients through all of their exposed surfaces. There are three main groups: the liverworts, the hornworts, and the mosses.

What are four main groups of plants?

These are the mosses (non-vascular plants), the ferns (seedless, vascular plants), gymnosperms and angiosperms. The latter two groups are both vascular plants that produce seeds.

Where do seedless plants grow?

Most seedless plants live in damp and shady habitats. Certain types of mosses, called PEAT MOSSES, grow in vast expanses of wetlands in the northern parts of the world.

Is not seed of a plant?

Not every plant grows from a seed. Some plants, like ferns and mosses, grow from spores. Other plants use asexual vegetative reproduction and grow new plants from rhizomes or tubers. We can also use techniques like grafting or take cuttings to make new plants.

What are unwanted plants called?

A weed is a plant considered undesirable in a particular situation, “a plant in the wrong place”. Many plants that people widely regard as weeds also are intentionally grown in gardens and other cultivated settings, in which case they are sometimes called beneficial weeds.

What are plants that don’t have seeds?

Plants are classified into two groups: seed plants and nonseed plants. Ebony spleenwort is a delicate, small fern that resembles a Christmas fern.

What kind of plant has no true roots?

Like most seedless plants, ferns produce spores that are dropped from the fern to the ground for reproduction. Moss is a seedless plant that has no true roots. Moss grows naturally on wet rocks, damp tree bark and in and around muddy ponds and streams.

How are the seeds of an angiosperm different from the flowers?

Angiosperms seeds are enclosed in fruit and include flowering plants. The male flowers are often small, while female flowers are larger. Once these flowering plants are pollinated, the flower and its reproductive parts dry up and fall away and the plant develops fruit or enclosed seeds. Flowering plants often have flat leaves with veins.

What does gymnosperm stand for in plant category?

Gymnosperm means “naked seed” as the seeds are not produced inside a fruit as they are in the flowering plants. Gymnosperms don’t make flowers, the pollen is produced from male cones. The group are mainly evergreen woody shrubs and trees, though as in any group, not all members follow the commonest pattern.
