1 13.2 The Vascular Plant Body (textbook p ) Learning Goal: Label and explain the anatomy of the Vascular Plant and it's Tissue Types Plants are classified into two main groups: and. Vascular plants have two organ systems: and. See text p544 Fig.13.7: Label two main "systems": Listen to "Hank": Crash Course on Vascular Plants Provide 5 interesting facts from Hank: 1

Read text p545 546: Plant cells have a, which provides to the plant, a, and, which are used

2 Read text p : Plant cells have a, which provides to the plant, a, and, which are used to carry out. Types of Plant Cells: Cell Type: Function: Parenchyma Collenchyma Sclerenchyma 2

3 text p547 Plants have four main types of tissue: meristematic tissue: dermal tissue: ground tissue: vascular tissue: Meristematic Tissue Throughout their lives, plants can continue to in their, which all vascular plants have. These tissues make up areas of. As these cells mature, they can develop into. Meristematic tissues are located in. 3

4 Dermal Tissue The outer covering of a plant is made up of. The is a single layer of that forms a covering over the of non woody plants and young woody plants. Older woody plants also form dermal tissue, called, which is produced as part of. It replaces the to from cork in woody stems and roots. Specialized Epidermal Tissue Part Function/Definition Guard Cells & Stomata Trichomes Root Hairs Draw a labelled diagram to show the relationship between a "guard cell" and a "stoma": 4

5 Ground Tissue Ground tissue forms most of the plant's and material, and it contains parenchyma cells, collenchyma cells, and sclerenchyma cells. Ground tissues have a, including. In some stems, roots, and seeds, the cells of ground tissue store starch and oils. Ground tissue also provides for the plant when it grows between other types of tissue. Vascular Tissue Vascular tissue is an system of that run throughout the of a plant, connecting the. The function of vascular tissue is to. Part Function/Definition Xylem Phloem 5

6 13.3 Plant Organs and Their Functions (textbook p ) Learning Goal: Label and explain Plant Organs text p552 Plants must absorb and from below the surface. From above the ground, plants take in and absorb. The ability to acquire these resources depends on three basic plant organs:,, and. What are the three main functions of roots? Provide an example of a plant (name and depth):... that has a shallow root system:... that has a deep root system: 6

7 Root Structure and Function: Part Function/Definition Root Cap Apical Meristem (Outer Root Layers) Root Hairs Cortex Casparian Strip (Inner Root Tissue) Xylem Phloem 7

8 text p554 The two major types of root systems are: and Briefly describe the structure and appearance of the following, and provide an example for each: Tap root: Fibrous root: Modified root: Aerenchyma root tissue: 8

9 Ch 13.2,13.3,13.4 Vascular Plant, Organs & Transport.notebook text p555 There are many types of stems, varying from and ( ) to and ( ). The main function of a stem is to provide for the plant's and structures. Fig Briefly explain what this picture represents? There are many adaptations of that help plants to. In some plants, stems are used to store food. In others, stems help plants withstand,, or. Name and explain 5 different types stem adaptations: text p556 Leaves come in many different and. Even the way that leaves are on the stem, and the of leaves on a plant, varies from species to species. Despite their amazing variety, the main function of all leaves is the same to the energy from the into the energy of through the process of. 9

10 The structure of a typical leaf has a portion called the, which has a relatively large area. In some species, the blade attaches directly to the. In other species, the blade attaches to the stem via a structure called a. External Structures of Leaf: Part Function cuticle Internal Structures of Leaf: Part Function (detailed) mesophyll palisade mesophyll spongy mesophyll Label the Leaf Structure: 10

11 text p557 The differences in the,, and of leaves are all clues that can help to a plant species. The blade of a leaf is not divided into parts. The blades of leaves are divided into smaller. A leaf's is the is another characteristic that can be used to identify plants. Label the Characteristics Used to Identify Leaves: 11

12 text p558 Flowering plants may be divided into groups based on the of seed in their. These seed leaves, called, are the source of for seedlings before leaves are capable of photosynthesis. Some plant embryos have cotyledon, so they are called. Other plant embryos have cotyledons, so they are called. Comparing Monocots and Dicots: Characteristic Monocots Dicots Number of Embryonic Seed Leaves Organization of vascular tissue in roots and stems Venation Number of Flower Parts Presence of Wood Root System 3 Examples 12

13 13.4 Transport in Plants (textbook p ) Learning Goal: Understand and appreciate complex transport system within plants for food production and movement, and gas exchange text p560 Vascular plants have a system to transport and from one part of the plant to another. Essentially, a plant is a with its embedded in the. The base of the tube is the, and the are at the top of the tube. For a plant to, two kinds of processes must occur. First, and other made in the by must be carried to all other living in the plant. For this to happen, that contains the carbohydrates must and the tube. Cells in the perform this function. Second, and dissolved in the must be by the and transported to cells in the and in other parts of the plant. In this process, water the tube. Cells in the perform this function. 13

14 text p560 Label this diagram: How Water and Nutrients Move Into and Out of Plant Cells: Particles move according to the difference in concentration between two areas. Explain the following concepts and how they work in plants: Diffusion: Osmosis: Active Transport: 14

15 Transport in the Xylem: The root cells contain a higher concentration of dissolved nutrients than the surrounding soil, so water moves into the roots by. Water moves through the cell walls into the spaces within the root, and enters the. The water in then transported in the xylem tissue up through the root into the. Within the stem, water moves by into other tissues of the plant. Minerals usually move cell membranes through. Explain the following concepts and how they work in plants: Root Pressure: (Pushing Water Up Against Gravity) Transpirational Pull: (Pulling Water Up Against Gravity) 15

16 text p563 Provide the steps to explain "transpiration": 16

17 Transport in Phloem: What is "translocation"? Translocation in phloem moves sucrose from a "source to a sink" list two sources and two sinks for sucrose in plants: Define "pressure flow model": How are plant nutrients moved through phloem? Draw a detailed diagram to explain: Summary: Watch the following animation video to see how water and sugar are transported in vascular plants: 17

The three principal organs of seed plants are roots, stems, and leaves.
