how are cycads and ferns alike?

Cycad and fern leaves have a central stalk flanked by rows of leaflets on both sides. But these similarities are merely superficial. Each plant reproduces very differently. Cycads produce cones from their trunk, whereas ferns bear spores on the undersides of their leaves.

Why are the things so darned expensive? Just about everything to do with cycads makes them cost more. First you need a male and a female plant which both decide to produce a cone the same year. The rare cycads don't do this very often (one reason they're rare), and the pollination rate is usually poor.

With ferns, according to the aspca database, you need only avoid: The very toxic Cycads (not really a fern, but also known as “Fern Palm” and Sago Palm) and the mildly toxic Asparagus Fern (aka Asparagus, Emerald Feather, Emerald Fern, Sprengeri Fern, Plumosa Fern, Lace Fern, Racemose Asparagus, Shatavari, Asparagus ...

These plants are mostly homosporous - their spores are identical and you can't differentiate which will grow into male or female plants. They are also monoecious - both the archegonia and antheridia (male and female reproductive structures) are borne on the same plant.

The leaves of ferns are often called fronds. Fronds are usually composed of a leafy blade and petiole (leaf stalk). Leaf shape, size, texture and degree of complexity vary considerably from species to species. A fern leaf or frond.

In higher plants like ferns and fern allies, the sporophyte stage is dominant. Gametophytes produce gametes (sperm and eggs) in a special structure called a gametangium (-ia), while sporophytes produce spores in a special structure called a sporangium (-ia).

Ferns have 3 major parts – the rhizome, the fronds and the reproductive structures called sporangia. The characteristics of each of these 3 parts of the fern plant are used for classification and identification. ... A laterally growing rhizome that creeps along or under the ground. It may even climb up a tree.

Similarities between Bryophytes and Pteridophytes Ø Both Bryophytes and Pteridophytes are land plants. Ø Both possess distinct Gametophytic and Sporophytic generations. Ø Both groups show heteromorphic alternation of generation. Ø Rhizoids are present in Bryophytes and Pteridophytes.

Like mosses, ferns have a primitive method of fertilization that involves a multiciliate sperm that swims through water to reach the egg. The gametophytes and sporophytes of ferns are photosynthetic and autotrophic. Flowering plants (angiosperms) belong to the vascular plant division Anthophyta.

Seedless vascular plants tends to be like ferns. Unlike mosses (bryophytes) they do have vascular tissue, which is why they have long leaves, or fronds though psilotum (whisk ferns) and equistem (horse tails) don't look like traditional ferns. Conifers are gymnosperms. The are not seedless, they have cones.

The cycad, a living fossil, is the ultimate plant for a changing climate. ... Cycads are dioecious, which means there are "two houses", with female plants and male plants, but until old enough for reproductive structures to form, the plants all look identical.

System of classification upon the evidence of a world designed by God. ... What is the difference between a taxonomic species and a biblical kind? The biblical kind is more intricate than the taxonomic kind. How do non-seed plants such as ferns reproduce?

Woodwardia fimbriata Giant Chain fern Sometimes called the “California Chain fern,” this massive fern is native to California and the western U.S. Semi-drought tolerant if planted in shade, it gets its adaptability to drought by an extensive root system.

Cycads. Cycads are ancient seed plants dating back over 200 million years. ... There are many Australian native cycads and three endemic genera: Bowenia, Lepidozamia and Macrozamia. Although they are very popular garden plants, cycads are threatened, endangered or extinct in the wild.

Answer and Explanation: A cycad is a type of gymnosperm, which means that it is a vascular plant. All gymnosperms, which are plants that produce cones in order to reproduce,...

The sporophyte of ferns is differentiated into true leaves, stem, and roots. In contrast, mosses lack true leaves, stem or roots. Ferns are vascular plants, but mosses are not. The main difference between mosses and ferns is the presence or absence of a vascular system.

Maidenhair Ferns are fantastic because they have frilly, fun leaves that are different from the usual thick leaves of indoor plants. Most ferns do well inside with low light (and ferns look great in terrariums).
