Slide 2 2010 Plants with a system of tubes Vascular Plants Mr. Harpers science mini lesson with audio Slide 3 Vascular (VAS kyoo ler) - having tubes to transport materials within an organism, such as blood in animals, or water and sap in plants. Important vocabulary arteries veins Slide 4 Vascular plant the type of plant that has tubes that carry materials to all the plants cells Important vocabulary Slide 5 Plants and animals are all made up of tiny living parts called cells. All living things, and every cell in them, must have food and water or they will die. Animal cell Plant cell Slide 6 Animal cells get the materials they need from blood. A circulatory system of tubes (blood vessels) carries blood to every animal cell. Slide 7 // Plants dont have blood but they still must get water and food to every cell. Slide 8 Nonvascular plants dont have tubes. They cant grow large because they wouldnt be able to move water and nutrients to cells deep inside. moss algae Slide 9 Non vascular plants are very small plants that dont need tubes to transport materials because every cell is close enough to the water (or air) to get what they need. There are several thousand nonvascular plants on this hand. Algae are tiny plants that make river water look green. Slide 10 Vascular plants have tubes to transport food and water to cells inside the plant. This allows them to grow much bigger than plants with no tubes. Slide 11 5 th graders learn about vascular plants and how their tube-like structures transport materials like water, minerals and sugar that every cell needs to live. Slide 12 Vascular plants i have a system of tubes that carry water and nutrients all through the plant. Slide 13 Most plants we see are vascular plants. Animals have one system of tubes to carry blood to all the cells. This is called the circulatory system. Slide 14 Vascular plants have two systems of tubes. Slide 15 Xylem are the tubes that carry water and minerals from the roots up the stem to the leaves. tzyhe plan (ZY lum) Slide 16 Sometimes the xylem are big enough to see when a plant stalk has been cut. Slide 17 Xylem (zie lem) are the tubes that carry water up the stem from the roots to the leaves. Phloem (FLO em) carry the sugar made in the leaves to all parts of the plant. Slide 18 Xylem (zie lem) are the tubes that carry water up the stem from the roots to the leaves. Phloem tubes carry a mixture of sugar and water called sap from the leaves to all parts of the plant. Tree sap Slide 19 Plants have two systems of tubes called xylem (ZY lum) phloem (FLO um) transport water and minerals up from the roots. transport sap (water and sugar) from leaves to every part of the plant. xylem phloem Slide 20 We can usually see the tubes when we look closely at a leaf. Slide 21 The stems of vascular plants have bundles of xylem and phloem tubes. Slide 22 Wood is made mostly of old xylem tubes. Slide 23 Plants are producers. They make food. Only plants can make food. Slide 24 The food that plants make is a chemical called sugar. All plants, even grass, has some sugar in it that animals can use for food. We may think of sugar as a sweet white substance that we sprinkle on cereal. That is pure, refined sugar. Slide 25 Plants make sugar in their leaves. A green material in the leaves called chlorophyll (CLOR ah fil) turns light energy from the sun into chemical energy (sugar). Slide 26 Plants cant grow without sugar energy. Animals cant live xxwithout sugar energy. Slide 27 Only plant cells that contain chlorophyll can make sugar. Slide 28 Chlorophyll is the reason that plant leaves are green. Slide 29 Chlorophyll in plant leaves is what converts sunlight energy into sugar. Slide 30 Xylem (zie lem) are the tubes that carry water up the stem from the roots to the leaves. Phloem tubes carry a sticky mixture of water and sugar called sap. Slide 31 The phloem tubes transport the sugar made in the leaves to every part of the plant for growth and storage. Slide 32 Different plants store sugar energy in different ways. (roots) (flowers) (fruit) (seeds) (stalks) (leaves) Slide 33 Animals eat plants to get the sugar energy to live and grow. Slide 34 The process of plants turning sunlight energy into chemical energy is called photosynthesis. (foh toh SIN theh sis) Slide 35 Plants must have three things in order to make food. light water CO 2 (Carbon dioxide) (for photosynthesis to happen) ? ? ? Slide 36 In order to make food plants must have: light water CO 2 (Carbon dioxide) Slide 37 CO 2 (carbon dioxide) is a gas that makes up less than 1% of Earths atmosphere. Plants cant make sugar without CO 2. Animals release CO 2 into the air as a waste product when they breathe. Slide 38 Plants take in CO 2 and use it as they make sugar (chemical energy). Plants release oxygen as a waste product as they make sugar. Slide 39 Plants cant live without CO 2 and must release oxygen. Animals cant live without oxygen and must release CO 2. Slide 40 This oxygen cycle is very important for life on Earth. Slide 41 Photosynthesis works like this + H 2 O + CO 2 Light (energy) (water) (carbon dioxide) C 6 H 12 O 6 O 2 sugar + oxygen Slide 42 H 2 O and CO 2 molecules are pressed together to become sugar molecules by the suns energy. A spare oxygen molecule is released in the process. Slide 43 OK, lets see how much you can remember. Slide 44 Review: What waste gas is released by plants? ? Slide 45 Review: What waste gas is released by plants? Oxygen oxygen Slide 46 Review: What gas is needed by plants? ? Slide 47 Review: What gas is needed by plants? Carbon dioxide CO 2 Slide 48 Review: What gas is released by animals as they live and breathe? Slide 49 Review: What waste gas is released by animals as they live and breathe? Carbon dioxide CO 2 Slide 50 Review: What is the name of the process in which plants make food from sunlight? Slide 51 Review: What is the process in which plants make food from sunlight? Photosynthesis Slide 52 Review: In what part of the plant is food made during photosynthesis ? Slide 53 Review: The leaves In what part of the plant is food made during photosynthesis? sugar Slide 54 Review: The leaves sugar In what part of the plant is food made during photosynthesis? Slide 55 Review: What is the name for the food chemical that plants make during photosynthesis? Photosynthesis sunlight + water + CO 2 sugar + oxygen ? ? Slide 56 Review: What is the name for the food chemical that plants make during photosynthesis? Photosynthesis sunlight + water + CO 2 sugar + oxygen ? ? sugar Slide 57 Review: What is the name for the food chemical that plants make during photosynthesis? Photosynthesis sunlight + water + CO 2 sugar + oxygen ? Slide 58 Where is sugar made ? Slide 59 In the leaves of plants Slide 60 Learn more with these Brainpop cartoons: Photosynthesis Plant Growth
