What do conifers produce?

Conifers produce cones, or strobili. Male cones, containing pollen and female cones, containing the eggs can both form on a single tree.

What is the gametophyte of conifers?

Gametophyte phase The gametophytes of conifers, like those of other seed plants, live out their brief, nonphotosynthetic lives almost entirely within the spore wall. All of their nutrition is derived from the parent sporophyte. The female gametophyte is never released from the tree until the seed matures.

What does the male conifer reproduce?

The Process of Coniferous Plant Reproduction Coniferous plants include some male cones that have pollen and some female cones that contain the ova. Once the pollen enters the female cones, seeds begin to form. The seeds continue to mature, and once they are complete the cones open and the seeds begin to spread.

Do conifers release pollen?

All conifers are pollinated by wind. Pollen may be produced in enormous quantities, particularly by species of true pine (Pinus), which can blanket the surface of nearby lakes and ponds with a yellow scum of pollen (the pollen can cause allergies in humans). Some conifers lack a pollination droplet mechanism.

Do conifers produce fruit?

In comparison to flowering plants, conifers do not produce flowers. The reproductive structures of conifers are the unsexual cones. More significantly, the seed of the conifers is not covered by the ovary; hence, they do not produce a fruit.

Do conifers produce flowers?

Conifers produce flower-like structures in the early spring, but technically, no, they don’t produce true flowers. Most people are familiar with conifer cones, although they tend to call all of them “pine cones.” In common with other members of the class Gymnospermae, pine trees have no flower or fruit.

How is the gametophyte formed?

A gametophyte is created when the sporophyte generation produces spores. Spores are made by meiosis or cell division that reduces the number of chromosomes by half. These haploid cells produced by sporophytes are spores. Spores will then undergo mitosis to grow into a multicellular haploid gametophyte.

Can a conifer produce seeds?

Conifers are woody plants and most of them are trees such as pine trees, firs, cypresses, junipers, cedars, and redwoods. Conifers reproduce using their cones. If the pollen lands on a female cone, then the female cone will produce seeds. The hard scales of the cone protect the new seeds as they grow.

What generation produces the pollen tube?

male gametophyte
A pollen tube is a tubular structure produced by the male gametophyte of seed plants when it germinates.

Where is pollen produced in a conifer?

pollen cones
Conifers often produce pollen cones lower in the tree than the seed cones. The wind is more likely to blow the pollen to another tree than up to the seed cones above on the same tree. This is particularly true of the firs, which produce seed cones near the treetop. Their pollen cones are typically lower in the tree.

Do bees pollinate conifers?

Other gnetophytes are pollinated by the wind. You can read an article about the gymnosperms from Tulane University and from the University of Wisconsin. So, the answer to your question is that, as far as we know, bees (native or otherwise) do not make use of the pollen of cedar trees or any other conifer.

Do conifers produce flower seeds?

Where does the gametophyte of a conifer live?

The gametophytes of conifers, like those of other seed plants, live out their brief, nonphotosynthetic lives almost entirely within the spore wall. All of their nutrition is derived from the parent sporophyte. The female gametophyte is never released from the tree until the…

What is gametophyte in plants?

The gametophyte is the sexual phase that produces sex cells in the development phases of algae and plants. The largest category of gymnosperm plants in which seeds are produced without fruits or flowers is called Conifers. Gymnosperms are called seed plants which are adapted to live on land.

How is the gametophyte formed in a fern?

When the spore wall cracks under appropriate moist conditions, the fern gametophyte is formed. The gametophytes of conifers, like those of other seed plants, live out their brief, nonphotosynthetic lives almost entirely within the spore wall. All of their nutrition is derived from the parent sporophyte.

Are pine trees gametophyte or sporophyte?

C is correct. Pine trees are the sporophyte stage of the pine life cycle; the plants we recognize as ferns and moss, on the other hand, are the gametophyte stage of their life cycles.
