Plant Classification
9
Plant Classification • Although all plants share common characteristics, they can be classified into groups: Non‐Vascular and Vascular plants. • Vascular plants can be classified into three subgroups:
Seedless plants
Seed plants ‐ Non‐flowering seed plants, ‐ Flowering seed plants
10
11
Non‐Vascular Plants • A non‐vascular plant doesn’t have specialized tissues to move water and nutrients through the plant. • So these plants depend on diffusion to move materials from one part of the plant to another (cell to cell). • Diffusion is possible because non‐vascular plants are small. • Mosses, liverworts and hornworts are examples of non‐ vascular plants.
12
13
Vascular Plants • These plants have specialized tissues to move materials through the plant. • These tissues are called vascular tissues, and can move water and nutrients to any part of the plant, which allows it to be of any size. • Vascular plants are divided into: Seedless plants and two types of plants with seeds. • Gymnosperms are non‐flowering seed plants. • Angiosperms are flowering seed plants.
14
Animal Classification
15
Animal Classification • The animal kingdom is divided in two major groups: Invertebrates and Vertebrates. • Invertebrates, are those animals that do not have a backbone. • Invertebrates live in water and on land. • There is a great variety of invertebrates, more than one million different kinds.
16
17
Invertebrates • These millions of invertebrates can be divided into 12 phyla. • Here are 8 of the most important ones: Cnidaria: Hydras, jellyfish. Platyhelminthes: Flatworms. Porifera: Sea sponges. Arthropoda: Insects. Mollusca: Clams, snails, squid. Nematoda: Roundworms. Echinodermata: Starfish. Annelida: Leeches
18
Simplest Invertebrates • The simplest invertebrates live in water, the place where animals first appeared. • At first sight, these invertebrates may look as plants. Example: Some cnidarians (anemones and corals).
19
Sponges and Cnidarians • They are brightly colored and sessile like plants (they don´t move from place to place). • One characteristic of animals is the ability to move around. • However, sponges, anemones and corals do move when they’re young and they don’t move when they’re adults. • Sponges feed by the passing of water and trapping of food particles through pores in its body. • Most cnidarians have armlike structures called tentacles with stinging cells around the mouth that help them capture the prey. Although they don’t have a brain they have nerves and muscles.
20
Flatworms and Roundworms • Flatworms are the simplest worms. If you cut a flatwom by the middle, one half looks like the other. • They have a head, a tail, and only one opening, the mouth. • Planarians are flatworms that live in fresh water. One feature you can see is the “eyespots”, as part of the nervous system, that includes a simple brain. • Some flatworms (plateworms) live inside the body of another organism. They feed off digested food from that organism. • Roundworms have a tubelike body, that comes to a point at each end. • They have a digestive system with two openings (mouth and anus). • Roundworms may live in soil, fresh water, or salt water, and also inside other animals.

Complex Invertebrates
MOLLUSKS • They are found on land, fresh or salt water. • They have soft bodies covered with a mantle. In many mollusks, the mantle forms a hard shell. • The organ systems are underneath the mantle. • They feed by moving around through a “foot”. • You can tell different classes of mollusks depending on the food and the shell. • Examples: Snails, clams, oysters. • Octopuses and squids are the most complex class of mollusks. They have tentacles to move and to capture prey. • Octopuses have no shell. Squids have a shell on the inside.
25
26
Complex Invertebrates
Segmented Worms • Earthworms and leeches are segmented worms. • Their bodies are made up of segments, or rings. • They have a tube‐shaped digestive system with two openings. • The worm has a circulatory system with hearts and blood vessels. They also have nerves. • These structures enable the animal to respond to light, temperature, and moisture. Earthworm
27
Complex Invertebrates
Equinodermata • They are very different from any other invertebrate. • One main difference is a kind of water‐pumping system. • Water‐filled vessels extend from the mouth into the arms of the animal. • The water is pumped to the tube feet, structures that help the animal grasp and move.
28
Complex Invertebrates
Arthropods • Two‐thirds of the species on Earth are arthropods (around 1,000,000,000). • Members of this phylum live in almost every part of Earth. • One group of arthropods, the insects, holds more different species than all the other species of living things combined. What do Arthropods have in common? • They have jointed limbs, including legs for walking and jumping. Some have jointed wings, flippers or claws. Their bodies are in sections. • They have an outer skeleton, or exoskeleton. • The major classes of the arthropods are: • arachnids, insects, and crustaceans.
