Spermatophyte

"Spermatophyte" Meaning

A type of plant, especially one whose seeds have an embryo surrounded by food stored in a photosynthetic, non-reproductive part, such as a seed leaf (cotyledon) and later in seedling stage, a true foliage leaf, characteristic of and most common in the plant division Spermatophyta, which includes ferns to flowering plants.

"Spermatophyte" Examples

Spermatophyte Usage Examples

Definition: A type of plant that produces seeds, also known as a flowering plant or an angiosperm.
The phylogenetic analysis indicates that spermatophytes are a distinct group of plants that evolved about 300 million years ago.
The tetraploid annuals are considered a distinct group of spermatophytes that have four times the number of chromosomes of the diploid ancestors.
Spermatophytes have various defense strategies against herbivores, such as the production of chemical compounds that are toxic or unpalatable to them.
The evolution of spermatophytes is credited to the development of flowers, which allowed for the dispersal of seeds and the increase in genetic diversity.

"Spermatophyte" Similar Words

Spermatoon

A spermatocyte or spermatid is the immature form of a sperm cell in the male reproductive system, but a spermatoon is an older term that specifically refers to the immature, rounded form of a spermatozoan (sperm cell) that undergoes spermatogenesis and is found in the testes or epididymis.

Spermatophore

A spermatophore is a structure produced and discharged by male animals, typically during copulation, that contains sperm cells and other elements necessary for fertilization. It is found in various species, including insects, mollusks, and some vertebrates. In more detail, a spermatophore is a package or capsule that is formed from the male reproductive material, often a spermatophytic structure, and is released during mating. It contains sperm cells, usually with additional substances like nutrients, adhesives, and even antimicrobial compounds that help the sperm survive and facilitate fertilization. The concept is often demonstrated in various animal classes: 1. Insects: In some insect species, such as certain spiders, and scorpions, and some flies, the male transfers a spermatophore, which is a capsule containing sperm along with a seminal fluid, to the female during mating. The spermatophore adheres to the female genital opening, and the sperm can be transferred inside the female's body for fertilization. 2. Mollusks: In some mollusks, including sea slugs and land snails, a spermatophore is also involved. Males produce spermatophores that they emit in a signal to the female; the female then picks up the spermatophores to use for fertilization. 3. Fish and some amphibians and reptiles: In some species of these classes, especially in salmon and other fish, but also in some species of flatworms and even certain frogs, the male discharges the milt, which is the fluid containing the spermatophores, next to the female's body, and then fertilizes her genital opening or a reproductive opening. The process of transfer of the spermatophore to the female can vary significantly across species, with males seeking out females, using complicated courtship behaviors to attract and then successfully transfer spermatophores for fertilization.

Spermatophores

Spermatophores are structures that contain sperm, specifically used for fertilization in certain invertebrates such as insects, mollusks, and echinoderms. They are typically used in mating and reproduction to transfer sperm from the male to the female. In some species, the spermatophore may also provide nutrients and other substances necessary for fertilization. In entomology, a spermatophore is also the structure that contains sperm and seminal fluids in the male insect's abdomen, which is transferred to the female during mating. In general, the term "spermatophore" can refer to any structure that contains and delivers sperm for fertilization purposes.

Spermatophoric

Spermatophorous

Spermatophorous refers to the carrying or bearing of sperm in the case of certain animals, particularly snails and slugs. In these gastropod mollusks, the spermatophore is a structure used to transfer sperm from the male to the female during mating. Spermatophores are typically stick-like or thread-like structures that contain the sperm and can be transferred to the female's genital opening or directly into her reproductive tract.

Spermatophylax

In botany, a spermatophylax is a structure that resembles a nuptial gift, which is produced by a plant species to attract pollinators, typically insects or hummingbirds. This structure contains a combination of nutrients, often nectar, pollen, or other attractants, intended to promote the health and potentially influence the reproductive behavior of the pollinator, leading to a more favorable pollination event for the plant.

Spermatophyta

Spermatophyta is a division of plants that produces true seeds, including trees, shrubs, and other vascular plants.

Spermatophytes

Spermatophytes are a subgroup of higher plants (embryophytes) that are characterized by producing seeds. The term is derived from the Greek words "sperma" (seed) and "phyton" (plant). Spermatophytes are also known as seed plants, and they are the most diverse group of plants, including gymnosperms (conifers, cycads, ginkgo, and gnetales) and angiosperms (flowering plants). Characteristics of spermatophytes include: 1. They produce seeds for reproduction. 2. They have vascular tissue (xylem and phloem) for transport of water, nutrients, and sugars. 3. They have roots, stems, and leaves. 4. They undergo alternation of generations (sporophyte and gametophyte). Examples of spermatophytes include: - Conifers (pines, spruces, firs) - Flowering plants (roses, daisies, sunflowers) - Oak, maple, and other deciduous trees - Grasses and cereals (wheat, oats, rice) - Palm trees and cycads.

Spermatorrhea

Spermatorrhoea

Spermatospore

Spermatozeugmata

Spermatozoa

The word "spermatozoa" refers to male reproductive cells, also known as sperm cells. They are tiny, motile cells that contain half the genetic material needed to fertilize an egg cell (ovum) during conception and form a zygote, which then develops into a fertilized embryo.

Spermatozoal

Spermatozoal refers to something related to sperm or semen. Specifically, it describes the structure, function, or content of spermatozoa, which are the male reproductive cells responsible for fertilization.

Spermatozoan

A spermatozoan (also known as sperm cell) is a male reproductive cell, specifically a cell of the reproductive system in animals. It is a minute cell that plays a crucial role in the fertilization process, carrying genetic material from the male to the female reproductive cell.
