Mosses and Liverwort (Bryophyta)2. There are evergreen and deciduous types (which lose their leaves in winter), ferns for damp soils or for dry soils such as those found under trees. Alkaloids are found primarily in plants and are especially common in certain families of flowering plants. Nematodes, commonly known as roundworms, are a group of worms that make up the phylum Nematoda. Ask the students to get into groups of four and give them 7 to 10 minutes to come up with categories (no more than 3-4) that can be used to organize the plants on the board. CLASS: Angiospermae (Angiosperms) Plants which produce flowers: Gymnospermae (Gymnosperms) Plants which don't produce flowers: SUBCLASS: Dicotyledonae (Dicotyledons, Dicots) Plants with two seed leaves: Monocotyledonae (Monocotyledons, Monocots) Plants with one seed leaf: SUPERORDER: A group of related Plant Families, classified in the order in which they are thought to have developed … Leaves are mostly absent. Plantae are made up into four phylum: Angiospermorphyta (anthophyta), Coniferophyta, filicinophyta (pteridophyta), and Bryophyta, or flowering plant, conifer, fern, and moss, respectively. Gnetales . Lycopsida. These plants multiply through spores. Google Groups allows you to create and participate in online forums and email-based groups with a rich experience for community conversations. Alkaloids have diverse and important physiological effects on humans and other animals. Gymnosperms are further classified into four classes, namely, Cycadopsida, Coniferopsida (or Pinopsida), Gnetopsida, and Ginkgopsida. Learn more fun facts about plants by exploring plant adaptations in different environments. C) Bryophyta done clear. They also lack true leaves, stem and roots that can help them transport water and nutrients. They are the most primitive. D) Pteridophyta done clear. Plant Autotrophs. In scientific classification of Sunflower, Family is a main factor. In fact there are so many different types that collecting them can become addictive. Plants are classified into two main groups. Class. I. There was a lot of vocabulary in this lesson, so let's take a look at some important concepts and terms. Organize with favorites and folders, choose to follow along via email, and quickly find unread posts. Class definition, a number of persons or things regarded as forming a group by reason of common attributes, characteristics, qualities, or traits; kind; sort: a class of objects used in daily living. Scientists currently consider that New Zealand has approximately 230 species of fern in about 50 different genera. In his system for classification of all known plants and animals, Carl Linnaeus (1707–1778) divided the plant kingdom into 24 classes, one of which was the "Cryptogamia". The chytrids are the simplest and most primitive Eumycota, or true fungi. Conifers (Gymnosperms)4. Botanists (plant biologists) seem to like changing their minds about what groups plants belong to even more than zoologists (animal biologists) do about animals. 4. Two particular groups of charophyte, the Coleochaetales and the Charales, resemble the earliest land plants (bryophytes) in a variety of ways, including the structure of their chloroplasts and sperm cells, and the way their cells divide during mitosis . The sporophyte is homosporous synangium. I. They lack vascular tissues and wood that can give them structural support. Express yourself. They make up more than 250,000 species, and are second in size only to Athropoda. The remaining plant species are all vascular (they have a system for circulating fluids). Sporophyte Definition. A brief sketch cannot in any sense capture the breadth and variety of the many mosses, ferns, flowers, trees, lichens, shrubs, algae, and grasses that currently live on planet Earth. Class divides plants into the two large groups, Dicots and Monocots. This is a good thing, since not only do they turn carbon dioxide into oxygen, they are a good food source for most of the creatures on earth. With small leaves around the stem, these plants grow anywhere from 7 inches to 26 feet tall, depending on species. Sunflower family is the family in which it has some properties in common with other plants in that family. Megaphylls are the large leaves that some pteridophytes have. Mosses - Bryophyta Mosses are non-vascular plants -- they cannot transport fluids through their bodies. 4. The stem is photosynthetic and dichotomously branched. The Plant List (TPL) was a working list of all known plant species produced by the botanical community in response to Target 1 of the 2002-2010 Global Strategy for Plant Conservation (GSPC). As with the ferns, lycophytes produce spores for reproduction and are … Alkaloid, any of a class of naturally occurring organic nitrogen-containing bases. Methanogens are a diverse group of microorganisms belonging to the archaea domain. The Resurrection Fern The distinctive characteristics of plants belonging to these two groups of angiosperms are summarized in the table below. A. Dicotyledons (Dicots are plants with two seed leaves. For each class (except the Bryopsida, where there are too many orders) there is also a list of orders and a summary of numbers of families, genera and species. Ferns (Pteridophyta)3. Dicots have "net-veined" leaves, which means they have the familiar leaves with center vein plus branching veins running from it. Google Groups. Rhizoids are present. This is just a warm-up to get them thinking about ways of categorization. Vascular plants, also called "higher plants," make up some 90 percent of the plant kingdom. Lower vascular plant, formerly pteridophyte, also called vascular cryptogam, any of the spore-bearing vascular plants, including the ferns, club mosses, spike mosses, quillworts, horsetails, and whisk ferns.Once considered of the same evolutionary line, these plants were formerly placed in the single group Pteridophyta and were known as the ferns and fern allies. The first non-vascular plants would have resembled modern-day lichen. With well over 15,000 species identified today, they can be found in different habitats ranging from terrestrial to marine environments. The modern gymnosperms are commonly grouped under four orders: 1. Monocots vs. eudicots (mainly from Mader [2007] and Simpson [2010]). Plants may look simple, but the way they preserve their species is anything but. Well-differentiated plant body with adventitious root, stem, … Ferns constitute the second major grouping of plants and the next major step in plant evolution.
