All angiosperms have flowers, carpels, stamens, and small pollen grains. They are extremely successful plants and can be found all over the world.

Answer. All angiosperms have flowers, carpels, stamens, and small pollen grains.

Summary

• Plants are multicellular and eukaryotic, meaning their cells have a nucleus and membrane-bound organelles.
• Plants perform photosynthesis, the process by which plants capture the energy of sunlight and use carbon dioxide from the air to make their own food.

Angiosperms are plants that produce flowers and bear their seeds in fruits. They are the largest and most diverse group within the kingdom Plantae, with about 300,000 species. Angiosperms represent approximately 80 percent of all known living green plants.

While there are many ways to structure plant classification, one way is to group them into vascular and non-vascular plants, seed bearing and spore bearing, and angiosperms and gymnosperms. Plants can also be classified as grasses, herbaceous plants, woody shrubs, and trees.

Scientists have identified more than 260,000 kinds of plants. They classify plants according to whether they have body parts such as seeds, tubes, roots, stems, and leaves. The three main groups of plants are seed plants, ferns, and mosses.

Other Characteristics of Flowering Plants Angiosperms also have more efficient vascular tissues. Additionally, in many flowering plants the ovaries ripen into fruits. Fruits are often brightly colored, so animals are likely to see and eat them and disperse their seeds (see Figure below).

Fruits, grains, vegetables, trees, shrubs, grasses and flowers are angiosperms. Most of the plants that people eat today are angiosperms. From the wheat that bakers use to make your bread to the tomatoes in your favorite salad, all of these plants are examples of angiosperms.

Gymnosperms are vascular plants of the subkingdom Embyophyta and include conifers, cycads, ginkgoes, and gnetophytes. Some of the most recognizable examples of these woody shrubs and trees include pines, spruces, firs, and ginkgoes.

Angiosperm Examples Grains including rice, corn, and wheat are also examples of Angiosperm. In these plants, the pollination process is carried out by the wind. Other examples of Angiosperms include roses, lilies, Broccoli, kale, Petunias, Eggplant, Tomato, Peppers and sugarcanes.

Angiosperm diversity is divided into two main groups, monocot and dicots, based primarily on the number of cotyledons they possess.

The characters which distinguish the classes.

Gymnosperm, any vascular plant that reproduces by means of an exposed seed, or ovule—unlike angiosperms, or flowering plants, whose seeds are enclosed by mature ovaries, or fruits. The seeds of many gymnosperms (literally “naked seeds”) are borne in cones and are not visible until maturity.

The flowering plants, also known as Angiospermae (/ˌændʒioʊˈspɜːrmiː/), or Magnoliophyta (/mæɡˌnoʊliˈɒfɪtə, -oʊfaɪtə/), are the most diverse group of land plants, with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Like gymnosperms, angiosperms are seed-producing plants.

What is a pollinator? Insects (bees, wasps, moths, butterflies, flies, beetles) are the most common pollinators, but as many as 1,500 species of vertebrates such as birds and mammals serve as pollinators also.

Flowers are an adaptation that helps many plants make seeds to grow new plants. Some flowering plants use bright petals and sugar water called nectar to get insects to visit. Visiting insects help move pollen among flowers so seeds will form. Leave them there to make seeds to grow more flowers.)

Among the living bryophytes, liverworts are probably most closely related to the earliest land plants, since unlike hornworts, mosses, and all vascular plants they do not possess stomata .

The correct order of evolution is C- Non Vascular, Vascular seedless, Gymnosperms, Angiosperms.

The lycopods or lycophytes are one of the oldest lineages of living vascular plants. They first appeared in the Silurian period (425 million years ago), and became extremely diverse by the late Carboniferous period (323-298 million years ago) and some species grew as trees more than 100 feet tall.

Green algae are the most closely related to the vascular plants.

Organisms 2 and 3 are most closely related because they have the same family name.

Which species are more related? In a phylogenetic tree, the relatedness of two species has a very specific meaning. Two species are more related if they have a more recent common ancestor, and less related if they have a less recent common ancestor.

Family snapshot – chimps and humans are very closely related. Similarities are often easy to see when one looks at two organisms that evolved from a common ancestor, and until recently, looking at physical features and behavior was the only way to determine how closely related two organisms are.

Types of Evolution

• Divergent Evolution. When people hear the word “evolution,” they most commonly think of divergent evolution, the evolutionary pattern in which two species gradually become increasingly different.
• Convergent Evolution.
• Parallel Evolution.

Cladistics describes evolutionary relationships and places organisms into monophyletic groups called clades, each consisting of a single ancestor and all its descendants.

On this tree, the outgroup is the fairy shrimp a group of crustaceans that are closely related to the insects. Note that some evolutionary trees don’t include an outgroup. Root: The root is the branching point that represents the last common ancestor of all the other lineages on the tree. Not all trees are rooted.

An out-group, conversely, is a group someone doesn’t belong to; often we may feel disdain or competition in relationship to an out-group. Sports teams, unions, and sororities are examples of in-groups and out-groups; people may belong to, or be an outsider to, any of these.

Because John belongs to a different group than George, he is an outgroup member to George. Ingroup and outgroup classifications aren’t just for werewolves and vampires. Everyone belongs to some groups; your race, gender, favorite sports team, your college, even the place you were born are all examples of groups.

No, they are not the same. When we construct a phylogenetic tree, we branch the organisms on the basis of their evolutionary history.

The outgroup is used as a point of comparison for the ingroup and specifically allows for the phylogeny to be rooted. Because the polarity (direction) of character change can be determined only on a rooted phylogeny, the choice of outgroup is essential for understanding the evolution of traits along a phylogeny.
