1. How do you DECIDE what makes a plant a plant? Examples: If it has a ________, I know it’s a plant. If it does__________, I know it’s a plant. STATE which are plants and which are NOT, then EXPLAIN HOW YOU KNOW. Give EVIDENCE for your statements.

2. Topic 10: An Overview and Classification of Plants EDGENUITY HOMEWORK: 14.7 due next class!

3.  Eukaryotic  Multicellular  Autotrophic REVIEW: What do these words mean?

4. What do you think each of these 4 plant organs DOES for the plant? The Flower will produce the fruit

7. Roots The three functions of roots are 1.absorb dissolved nutrients and water from the soil 2.anchor the plant 3.store food The root tip is the place where the roots are GROWING! A single tap root with hairs Fibrous Roots Magnified Root Hairs (increase surface area for absorption of water and nutrients)

8. Stems The 4 functions of stems are 1.to support the plant 2.connect the roots and the leaves 3.transport water and minerals UP the stem 4.transport glucose and other nutrients that the plant makes DOWN to the roots for storage or UP to the area where the glucose is needed for cellular respiration.

9. Leaves The 3 major functions of the leaf are: 1.capture as much light energy as possible 2.take in CO 2 3.to make food (glucose) during photosynthesis.

10. Tissue Type Description Why Does the Plant Need It? Major Feature(s) Similar to What in Humans? Dermal Meristematic Vascular Ground

11. 4 Plant Tissues 1.Dermal tissue 2.Meristematic tissue 3.Vascular tissue 4.Ground tissue Dermal tissue – light blue Meristematic tissue - red Vascular tissue – purple Ground tissue – yellow

12.  Thick, waxy, tough  Protects the outside of the plant from damage, predators, viruses, bacteria, fungi, and protects it from water loss  Found on the surface of leaves and stems-called the epidermis  Contains trichome, guard cells, dermal tissue cells, stoma and waxy covering called the cuticle.

14. 2. Meristematic Tissue A plant continues to GROW as long as it lives because plants have meristems, the only cells that continually divide by the process of mitosis, generating new cells. One example of a meristem is a Root apical meristem, located at the tips of the roots just behind the root cap, provides elongation of the plant down into the soil. Growth in length of roots is concentrated near the root’s tip. The root tip is protected by a root cap, which secretes a substance (enzymes) that helps digest the earth as the root tip grows through the soil.

15. Shoot apical meristem located in the buds allow plants to grow up into the air (growth) Three Types of Meristem Tissue Lateral meristem located in the stem and allows the plant to grow more girth or thicker Root apical meristem located in the root tips and allows for the growth of the roots through the soil

16. Stem cells! These are cells that are no particular body part that can become any body part that is needed. These cells may remain in a non-dividing phase for long periods of time until they are activated by a normal need for more cells to maintain tissues, or by disease, or tissue injury.

17.  A system of hollow tubes, like a pipeline  Transports ◦ water and nutrients through roots, stems and leaves ◦ glucose throughout the plant  2 types of vascular tubes: ◦ Xylem= water (transpiration) ◦ Phloem= food (glucose) Purple

18. Vascular Cambium is meristem (cells that divide) that makes the vascular tissue of the plant: Xylem (water transport) and Phloem (sugar transport) What make the vascular tissue in a plant?

19. Vascular Cambium A cylinder of meristematic tissue in woody plants that adds layers of secondary vascular tissue called secondary xylem (wood) and secondary phloem. Located in the stem and roots New cells produced on the inside and outside….xylem on the inside and phloem on the outside

21. Cells that lie between dermal and vascular tissues  Storage of sugar in roots and fruits  Supports the plant—thick, rigid, structural  Site of photosynthesis in the leaves (parenchyma) ◦ Palisade mesophyll ◦ Spongy mesophyll YELLOW

22. Dermal Tissue Ground Tissue Vascular Tissue

23. Adipose tissue stores fat

24.  The purpose of the Lab Activity is to: ◦ Look at REAL roots, stems, and leaves ◦ To learn and use new vocabulary about the plant ◦ Work with your classmates to apply what you have learned today about these parts, what kinds of tissue they are made of, and what their jobs are in the plant.

25.  There are 7 Lab Stations  You have 3-4 minutes at each station to LOOK at the plant part and to answer the questions about that part.  You have 1 minute to rotate and begin the next station.  If you do not finish you will have to come in at lunch or after school to finish!

26.  Complete 14.7 in Edgenuity!!  Due next class!!
