Living things are different but share similar structures(SC.F.1.2.3) By: Jorge Lallave
Grade Level Expectations • Students should distinguish common characteristics of vertebrate animals. Like mammals, birds, fish, reptiles, and amphibians. • Students should understands similarities and differences among plants. • Although plants and animals are different, they also share common characteristics.

How Scientists group living Things? Processes of Life USF/NSF/STARS
All kingdoms can be broken in small groups according common characteristics. A detail classification should includes the following steps in the ladder. Phylum –Second highest classification it covers different groups with a common physical characteristics. Class –Grouped families according a shared attribute. (mammals) Order– How the a class group survive? (carnivorous, herbivorous) Family – Taxonomic group containing one or more genera. Genus – The second smallest group Species –Smallest group whose members can interbreed. The science of classifying things is called Taxonomy. Classification goes beyond kingdom level Processes of Life USF/NSF/STARS
Classification beyond kingdom level Processes of Life USF/NSF/STARS
Animal Kingdom-is composed of living things made of many cells. They must eat other animals or plants to survive. Phylum • Vertebrate animals have backbone. Examples • Amphibians (moist skin, no scale) • Frogs, toads and newts. • Birds (wings,feather,beak) • Fish(fins, scales, gill) • Mammals ( hair, milk) • Dog, cats, bears. • Reptiles (dry, scale skin) • Snakes, turtles, alligator. Processes of Life USF/NSF/STARS
Animal Kingdom Continues Phylum • Invertebrate animals do not have backbone. Examples • Arthropods (joints, shells) • Crustaceans (crab, lobster) • Insects (beetles, ants) • Arachnids (spiders) • Mollusks (sea creatures) • sponge • Snails • leaches Processes of Life USF/NSF/STARS
Classifying the group of the animals according to the physical characteristics Vertebrate • Amphibians • Birds • Fish • Mammals • Marsupials • Primates • Cetaceans • Reptiles Invertebrate • Annelids • Arachnids • Crustaceans • Echinoderms • Insects • Mollusks • Protozoa Processes of Life USF/NSF/STARS
Plant Kingdom-iscomposed of all plants made of many cells with nuclei. Plants produce their own food. • Phylum • Vascular plants – have tubes on roots, stem, and leaves. • Examples • Trees, bushes, and ornamental plants • Seed plants • Angiosperms make their seeds in flowers. • Gymnosperms produced seed in cones (conifers, pine) Processes of Life USF/NSF/STARS
Plant Kingdom Cont’s… • Phylum • Nonvascular plants – don’t have tubes. • Examples • Lichens • Liverworts • Non-Seed plantsare able to produce new plants without seeds. (Sporea single reproductive cell) • Ferns • Mosses • Algae (1) (2) (3) (4) (5) Processes of Life USF/NSF/STARS
Botany is the study of plants. A scientist who studies plants is a botanist, and anatomy is a science that study how living things are including their parts. Two main types of root: taproot system, a single large root that grows straight down. fibrous root system, smaller branching roots. Plants Anatomy (1) (2) • Two main types of stem: • green stems are thin flexible tubes in a bundle that holds the plant. • woody stems grows taller and thicker every year. (3) (4) Processes of Life USF/NSF/STARS
Plants Anatomy Cont’s… The tubes which carry water are called xylem, and the ones that carry the food are called phloem. • Two main types of leaves • Needle leaves are thin pointed, and very tough. • Broad leaves, are wider and expose more surface to the sun. • Main parts of a leaf • Central stalk called the “petiole”. • Lamina is the blade of a leaf. • Veins carry the water and food. • Tiny holes microscopic in size, called “stomates”. • Midribis the central rib of a leaf.

Flowering plantshave a characteristics that all other kinds of plants do not have:Afloweras part of the plant where seeds are made. • Pistil- female reproductive tissue of a flower. • Style - is a long tube on top of the ovary, and below the stigma. • Anatomy of a flower • Anther - tip of a flower's stamen • Stamen- male reproductive organ, contains the pollen. • Filament- holds the anther and part of the stamen. • Ovary- is a female reproductive organ, base of the pistil. • Petal- leafy structures that comprise a flower. • Sepal- small leaves located directly under a flower. • Stem - supports the plant. • Stigma- uppermost part of the pistil, receives the male pollen. (I) Processes of Life USF/NSF/STARS
Classifying Leaves Students should classify different leaves according to their: LEAF SHAPES (Commonly-employed terms.) • Ovate-egg-shaped with the larger end at the bottom. • Elliptic-shaped like an ellipse, tapered at both ends and with curved sides. • Oblong-tapered to both ends, but with the sides more or less parallel. • Lanceolate-shaped like the tip of a lance. Processes of Life USF/NSF/STARS
Classifying Leaves LEAF SHAPES (Commonly-employed terms.) • Linear- long and thin, with the sides parallel. Like grass leaves. • Orbicular-nearly circular in outline • Cordate-heart-shaped with the wide part at the bottom • Hastate-with two basal lobes that point straight out Processes of Life USF/NSF/STARS
Classifying Leaves LEAF SHAPES (Commonly-employed terms.) • Sagittate-with two basal lobes that point backwards • Peltate-with the petiole attached to the center of the underside of the blade • Perfoliate-with the petiole appearing to run through the center of the leaf • Terete-circular in cross-section. Processes of Life USF/NSF/STARS
Common Characteristics Processes of Life USF/NSF/STARS
Different Characteristics • Animals move freely and plants are rooted in the soil. • Animals take in oxygen and give off carbon dioxide. • Animals do not make their own food and do not have chlorophyll. • Animal cells do not have a cell wall. • Animals eat plants, but plants do not eat animals generally. • Animals in general are more advanced in their structure than plants.
