How is seed formation in a conifer different than in a flowering plant?
At this level of taxonomy, there are gymnosperms and angiosperms. The gymnosperms have 'naked seed'. (Hence the gymno part of the name)The angiosperms have an ovary for producing seed, in conjunction with pollen.Earlier taxonomy has the ferns, mosses, and the non-vascular plants, seaweeds, and in New Zealand we have a a few species of Tmesipteris. These early plants do not have flowers, but the ferns at least have sexual reproduction.
Name 5 types of gymnosperms?
The five types of gymnosperms are conifers (pine trees, spruces, firs), cycads (palm-like plants), ginkgoes (Ginkgo biloba), gnetophytes (Ephedra, Gnetum, Welwitschia), and conifers (cypress, cedar, juniper).
What is the plant life on the Paleozoic Era?
The Paleozoic Era lasted 291 million years from the start of the Cambrian Period 542 million years ago until the end of the Permian Period 251 million years ago. Life of every kind went through great changes. The first evidence for plants predate the Paleozoic Era. Evidence that resembles green algae is found in rocks in the late Proterozoic Eon but exact classification into the Kingdom Plantae has not been confirmed. The first confirmed plants come from the Cambrian Period(542 - 488.3Ma). They take the form of simple green algae possibly of the order Dasycladales. These normally live in aquatic environments. It is during this period that we find evidence for the first plants on land. Fossil species closely related to the river plant Charales have been found in rocks from around this age. It was not until the Ordovician Period(488.3 - 443.7Ma) that the first Embryophytes evolved. Embryophytes is the clade of plants that contain most of the plants that you would recognise. These plants are primarily land plants although some species are considered semi- aquatic. Fossils from this period are fragmentary and exact classification is difficult. The Silurian Period(443.7 - 416Ma) gives us the first complete fossils of Embroyophytes. This is the time in history that we can confirm wide spread land plants. Species such as the extinct Lycopodiophyta Baragwanathia longfolia become common in terrestrial environments. During the Devonian Period(416 - 359.2Ma) we see the first evidence of the first trees. The earliest known trees the Wattieza & Archaropteris were closly related to ferns unlike most modern trees. They grew up into huge forests pumping vast amounts of oxygen into the atmosphere. By the Carboniferous Period(359.2 - 299Ma) these forests covered the land. Most of the coal on the planet are the remains of these huge forests. The levels of oxygen in the atmosphere were much higher than today as a result of these forest. It was this that allowed the arthropods to become massive. The first conifers appear at this time in history. The Permian Peroid(299 - 251Ma) saw the formation of the super-continent Pangaea. The interior of this continent was dominated by huge deserts. The changes in environment caused huge changes in the plants that dominated the land. By the end of the Permian the fern like trees, that had dominated for millions of years, had been replaced by conifers as the most common trees on the planet. The end of the Paleozoic Era was marked by the planets worst extinction event, the Permian-Triassic Extinction or "The Great Dying". It shows a clear decline in the conifer species and the beginning of the Mesozoic Era a resurgence of the Lycopdhates. It was not until the Mesozoic Era that plants that dominate most environments on land today such as flowering plants and grasses evolved.
Is a grape a gymnosperm or a angiosperm?
A grape is an angiosperm. Angiosperms are plants that produce seeds enclosed in a fruit, while gymnosperms produce seeds that are not enclosed in a fruit. Grapes are produced by flowering plants, making them angiosperms.
How are ferns and flowering plants different?
conifers are flowering plants
What do conifers and flowering plants do?
Photosynthesis
How are conifers like flowering plants?
Conifers and flowering plants are both types of seed plants that reproduce via seeds. However, conifers reproduce using cones, while flowering plants reproduce through flowers. Additionally, both types of plants have vascular tissue for transporting water and nutrients throughout their bodies.
Name of non flowering plant?
Conifers are non-flowering plants.
What do flowering plants and conifers make together?
Photosynthesis
Are conifers plants grow flowers?
Conifers resemble flowering plants in having seeds and well developed vasculature
Difference between conifer and flowering plants?
Conifers and flowering plants both produce seeds, but they are classified as completely different types of plants. While conifers are always trees (although some may appear to be shrubs), flowering plants can be trees, succulents and even grasses. However, there are several specific differences between the two that scientists use to tell them apart if there is ever any doubt.
What is it that grows into a new plant and is made by conifers and flowering plants?
seed
What is the difference between conifers and flowring plants?
A conifer is a flowering plant.
What are examples for non-flowering plants that make seeds?
Conifers and gymnosperms
What two categories are conifers and flowering plants divided into what does each name mean?
Conifers and flowering plants are divided into two categories: gymnosperms and angiosperms. Gymnosperms are conifers that bear naked seeds, typically in cones. Angiosperms are flowering plants that produce seeds enclosed within fruits.
Do all non-flowering plants reproduce by spore?
No. Conifers reproduce by seeds
