Lesson 1 Cells Lesson 2 Classifying Life Lesson 3 Plants Lesson 4 Classifying Animals How are living things similar? Lesson 5 Animal Systems organism cell unicellular multicellular chlorophyll tissue organ organ system What are cells? Cells are the smallest units of living things that can carry out the basic processes of life. frog cells amoeba cell What is inside an animal cell? vacuoles nucleus cytoplasm cell membrane mitochondria What is inside a plant cell? vacuole mitochondria nucleus cytoplasm cell membrane chloroplast cell wall How are cells organized? Cells form tissues, tissues form organs, and organs work together in organ systems. cell organ system tissue organ All of the cells, tissues, organs, and organ systems form an organism. Main Idea What is the main difference between the ways unicellular and multicellular organisms are organized? Unicellular organisms perform functions on their own. Multicellular organisms have special cells, tissues, and organs to do tasks. Vocabulary Chlorophyll is able to use the energy in sunlight. ___________ Similar cells working together at the same function form a ___________. A ___________ is the smallest unit of living things that can carry out the basic processes of life. A group of tissues working together to perform a specific function form an ___________. cell chlorophyll organ tissue Vocabulary Organs that work together to perform a certain function make up an _____________. Multicellular organisms are made of more than _____________ one cell. An _____________ is a living thing. _____________ organisms are made of a single Unicellular cell. multicellular organ system organism unicellular Compare and Contrast Plant cell: has chloroplasts, cell wall How can you tell the difference between a typical plant cell and a typical animal cell? Both: have cell membrane, organelles Animal cell: has many or no vacuoles End of Lesson organ system (ôr´gən sis´təm) A group of organs that work together to do a certain job. (p. 28) classification kingdom species vertebrate invertebrate vascular nonvascular How are organisms classified? Kingdom Phylum Class Scientists classify organisms by sorting them into groups according to shared characteristics. Order Family Genus Species What are animals? Animal Kingdom vertebrates fish invertebrates snake cow sponge dragonfly jellyfish What are plants and fungi? Fungus Plant Kingdom Kingdom nonvascular yeast morels mildew liverwort morels hornwort moss mold vascular rust smut mushrooms flowering plant penicillin fern corn smut pine tree What are bacteria and protists? Protist Kingdom Bacteria Kingdoms plantlike Ancient Bacteria hot springs bacteria red algae animal-like True Bacteriafungilike rod-shaped E. coli sphereshaped step paramecium spiral shaped orange Lyme disease slime mold What are viruses? Viruses are tiny particles that enter the body of a living thing, take over some of its cells, and cause the organism to get sick. Main Idea Which three kingdoms are mainly multicellular? Mainly unicellular? Multicellular: animals, plants, and fungi Unicellular: protists and bacteria Vocabulary The narrowest group an organism can be classified into is a _____________. The word _____________ means “contains tubes or vessels.” A _____________ is an animal with a backbone. _____________ Classification has been called the science of finding patterns. classification species vascular vertebrate Vocabulary Nonvascular plants do not have ____________ vascular tissue. The broadest group an organism is classified into is a ____________. An ____________ is an animal without a backbone. invertebrate kingdom nonvascular Classify How would you classify a multicellular organism that has cell walls but no chlorophyll? Fungi Not a plant Not an animal Does not move, multicellular Does not make its own food End of Lesson gymnosperm angiosperm xylem phloem cambium photosynthesis transpiration cellular respiration How are plants classified? Plants are classified as vascular or nonvascular. vascular seedless seed no flowers fern horsetail Douglas fir gingko flowers hydrangea gerber daisy What are roots? cortex A root is the part of the plant that absorbs water and minerals, stores food, and anchors the plant. root hair transport vessels root cap epidermis What are stems? Stems are plant parts with two functions: supporting the plant and transporting water, minerals, and sugars to different parts of the plant. xylem cambium phloem woody stem soft stem What are leaves? Leaves are plant parts that carry out the processes of photosynthesis and transpiration. cuticle epidermis vein xylem guard cells phloem stoma 5 What are leaves? Some water evaporates through open stomata. 4 Sugar is then transported in the phloem tissue. 3 Water in the leaves is used to make sugar. transpiration 2 1 Water moves through the xylem tissue up to the leaves. sugar Water enters the plant’s roots. water How are photosynthesis and respiration related? sunlight photosynthesis sugar + oxygen carbon dioxide respiration water Main Idea Why do all plants need air, water, and sunlight? Plants need these raw materials to carry out photosynthesis. Vocabulary Photosynthesis is the process by which ______________ a plant makes its own food. Xylem ______________ is a series of tubes that moves water and minerals up a plant’s stem. ______________ moves sugars that are made Phloem in the plant’s leaves to other parts of the plant. An ______________ is a seed plant that produces flowers. angiosperm phloem photosynthesis xylem Vocabulary Xylem and phloem cells are produced in the _________________. A _________________ is a seed plant that does not produce a flower. Energy is released when the cells of organisms use oxygen to break down sugars stored as starch in the process called _________________. The loss of water through a plant’s leaves is called _________________. cambium cellular respiration gymnosperm transpiration Draw Conclusions An insect cannot survive in a covered jar, even though the jar contains food and water. When a plant is added to the jar, the insect can now survive. Explain. plant in jar insect gets oxygen End of Lesson asymmetrical radial symmetry bilateral symmetry monotreme marsupial placental mammal What are simple invertebrates? Most lower invertebrates live in aquatic environments, which are filled with water or are moist. segmented worm roundworm flatworm sponge sea anemone What are complex invertebrates? Some invertebrates have specialized organs and complex body structures. What are vertebrates? Vertebrates are animals that have a backbone, bilateral symmetry, and an endoskeleton. What are mammals? Mammals are warm-blooded animals that produce milk to feed their young. Most mammals have hair or fur. Main Idea What is the main difference between vertebrates and invertebrates? Vertebrates have a backbone and invertebrates do not. Vocabulary Radial symmetry is a body plan in which ________________ all body parts of an organism are arranged around a central point. The young of a ________________ develops within its mother. A _______________ is a pouched animal. marsupial placental mammal radial symmetry Vocabulary A _________________ is a mammal that lays eggs. An _________________ body plan cannot be divided into mirror images. Bilateral symmetry is a body plan in which an _________________ organism can be divide along only one plane of their body to produce two mirror images. asymmetrical bilateral symmetry monotreme Main Idea and Details What characteristics identify birds? warm-blooded Characteristics of Birds two wings End of Lesson skeletal system muscular system digestive system excretory system respiratory system circulatory system nervous system endocrine system What are the skeletal and muscular systems? vertebrate skull pelvis rib femur What are the digestive and excretory systems? stomach intestines kidneys esophagus liver bladder What are the respiratory and circulatory systems? Two body systems that work together to provide oxygen and food to cells. 3 The oxygen-poor blood is pumped to the lungs. 2 In the lungs, the blood drops off carbon dioxide and picks up oxygen. 2 3 3 4 4 1 Oxygen-poor blood flows into the heart. 1 Oxygen-rich blood flows into the heart. Then it is pumped to the body. What are the nervous and endocrine systems? Two body systems that work together to control physical responses and body activities. Main Idea How are the circulatory, respiratory, skeletal, muscular, and nervous systems put into use when a rabbit runs from danger? Circulatory/respiratory: get blood with oxygen and food to leg muscles Skeletal/muscular: make legs move; nervous: sense danger, coordinate leg movement Vocabulary The vertebrate __________________ includes the brain, nerve cord, nerves, and sense organs. The power to actually produce movement is provided by the __________________. The __________________ is a long tube in which food is broken down into nutrients an organism can use. The __________________ consists of the heart and blood vessels. muscular system circulatory system nervous system digestive system Vocabulary The __________________ is made up of bones, tendons, and ligaments. The __________________ removes waste products from the body. The __________________ of a rabbit is made up of the lungs and the passageways that lead to them. The __________________ has glands which produce hormones. endocrine system respiratory system excretory system skeletal system Summarize heart pumps What steps take place in the rabbit’s body to bring blood to the body cells? blood travels oxygen in cells steps to bring summary blood to cells End of Lesson
