spore (n.)

reproductive body in flowerless plants corresponding to the seeds of flowering ones,” 1836, from Modern Latin spora, from Greek spora “a seed, a sowing, seed-time,” related to sporas “scattered, dispersed,” sporos “a sowing,” from PIE *spor-, variant of root *sper- “to spread, sow” (see sparse).

Is moss a spore?

A moss is a flowerless, spore-producing plant – with the spores produced in small capsules. … The spore capsule, often with a supporting stalk (called a seta), is the sporophyte and this grows from the gametophyte stage. You will commonly see the statement that a moss gametophyte consists of leaves on stems.

What organisms use spores?

Spores are single-celled reproductive units produced by many different organisms, including plants, fungi, and bacteria. Spores are primarily used for asexual reproduction, although some bacterial groups use spores to survive harsh conditions.

What’s the difference between a spore and a seed?

The main difference between spores and seeds as dispersal units is that spores are unicellular, the first cell of a gametophyte, while seeds contain within them a developing embryo (the multicellular sporophyte of the next generation), produced by the fusion of the male gamete of the pollen tube with the female gamete …

What are moss spores called?

The spores (meiospores), which arise by meiosis, are shed from the capsule gradually through a variety of mechanisms. After the operculum (cover) of the capsule has been shed, its mouth is usually partially closed by the peristome (teeth) and sometimes by associated structures.

They are found contained in a casing, called sporangia, and grouped into bunches, called sori, on the underside of the leaves. Spores look like little dots and may be harvested for fern spore propagation by the intrepid gardener.
