1 SAY: How much sleep do you actually need
SAY: How much sleep do you actually need? A study was conducted and data was gathered on sleep recommendations for humans. Take a moment to look at this graph….(ask CFUs) Ask scholars these CFUs by cold calling randomly. What does this graph tell you? How do you know? What is on the x-axis? What is on the y-axis? What is the independent variable? What is the dependent variable? What do the colors indicate? How much sleep does a teen need? What is the relationship between the two variables? Why is it important to be able to read this information? Why is the skill of interpreting data presentations essential for adults?

2 Cover Your TAIL (line/bar graphs)
T: Title – the title clearly states what data the graph is representing A: Axis – the independent variable is on the X axis and the dependent is on the Y axis I: Interval – note the intervals on both axes L: Label – read the labels (legends, units) on the axes SAY: Before we dive into selecting data points, let’s review the basics of a line/bar graph and things we should consistently be looking at. We’ll use the acronym, “Covering your TAIL.”

3 College Completion Rate and ACT score
Model by doing a think aloud on how to read this by using “Cover your TAIL” SAY: In order for me to understand this information, I’m going to cover my TAIL. This is a complex graph, because it has more than 2 variables. T is for “Title” – What is my title here? A is for “Axes” – What is on my x axis? What is on my y axis? What is my independent variable? What is my dependent variable? I is for “Intervals” – What are the intervals on the x axis? How about on my y-axis? L is for “Labels” – What are my labels here? What are my units? What is this graph telling me?

4 -Which GPA has the highest college completion rate with a mean ACT score of What does the line overall 6 year completion mean. When you model this for scholars, tell them that they should use the legend and actually WRITE next to the line!!!

6 Warm Up In your groups, List all the vegetables you can in 1 minute.
List all the ______ you can in 1 minute. What is the difference between the two?

7 copyright cmassengale
Vegetables are usually grouped according to the portion of the plant that is eaten such as leaves (lettuce), stem (celery), roots (carrot), tubers (potato), bulbs (onion) and flowers (broccoli). A fruit is the mature ovary of a plant. So a tomato is botanically a fruit but is commonly considered a vegetable copyright cmassengale

8 Kingdom of Plants Plants are alive, just like people and animals.
They grow and die. They need energy, nutrients, air, and water. They produce young. They are made up of cells. They react to what's around them.

10 What Do Plants Need to Make Food?
How do they make their food?!?

11 Plant Physiology Plants are photosynthetic -- they gather their food energy directly from sunlight To perform photosynthesis, plants need to have a supply of: Sunlight Carbon dioxide gas from the atmosphere Water Mineral nutrients

12 Basic Plant Structure Plants have three vegetative organs: roots,
stems, and leaves.

13 root root tip root hairs

14 Roots 1 Roots anchor plant in soil, absorb minerals & water, & store food fibrous roots (1) mat of thin roots that spread out monocots tap roots (2) 1 large vertical root also produces many small lateral, or branch roots dicots root hairs (3) increase absorptive surface area 2 3

15 ROOT SHOOT (stem) root tip root hairs nodes buds internodes
terminal or apical buds axillary buds flower buds & flowers

16 Modified shoots stolons (strawberries) rhizome (ginger) tuber (potato)
bulb (onion)

17 Stem System Holds leaves, transports and stores water and nutrients, and is sometimes photosynthetic.

18 root shoot (stem) leaves root tip root hairs nodes buds
internodes buds terminal or apical buds axillary buds flower buds & flowers leaves mesophyll tissue veins (vascular bundles)

19 Interdependent systems
Both systems depend on the other roots depend on sugars produced by photosynthetic leaves shoots depend on water & minerals absorbed from the soil by roots sugars water & minerals

20 Leaves Function of leaves simple vs. compound photosynthesis
energy production CHO production gas exchange transpiration simple vs. compound

21 Modified leaves tendrils (peas) spines (cacti) succulent leaves
colored leaves (poinsetta)

26 What Do Plants Need to Make Food?
Plants make food in their leaves.  The leaves contain a pigment called chlorophyll, which colors the leaves green.  Chlorophyll can make food the plant can use from carbon dioxide, water, nutrients, and energy from sunlight.  This process is called photosynthesis.

27 Plant Adaptations to Land
Solutions: Roots absorb H2O & minerals Lignin & cellulose in cell walls Vascular Transport System Waxy cuticle & stomata with guard cells Pollen containing sperm Problems: Need minerals Gravity Increase in Height for Light Adaptations for Drier environment Reproduction copyright cmassengale

28 Plant Characteristics
Multicellular Autotrophic (photosynthesis) Chlorophylls a and b in thylakoid membranes Surrounded by cell walls containing cellulose (polysaccharide) Store reserve food as amylose (starch) copyright cmassengale

29 How do plants make babies?

Plant Reproduction Alternation of generations life cycle Diploid (2n) sporophyte stage Haploid (1n) gametophyte stage Produce multicellular embryo protected inside multicellular haploid (gametophyte egg sac) tissue copyright cmassengale

31 copyright cmassengale
Plant Reproduction Diploid (2n) sporophyte stage produces haploid spores by meiosis Haploid spores undergo mitosis to produce gametophyte stage Gametophyte makes gametes (eggs and sperm) by meiosis Zygote (2n) produces the new sporophyte copyright cmassengale

32 Alternation of Generations
Gametophyte 2n Sporophyte 2n gametophyte 1n pollen 2n seed with plant embryo Ovary with 1n ovules (eggs) Sporophyte copyright cmassengale

Plant Divisions copyright cmassengale

37 copyright cmassengale
Taxonomy Plants are divided into two groups Based on the presence or absence of an internal transport system for water and dissolved materials Called Vascular System Vascular Bundles copyright cmassengale

38 copyright cmassengale
Vascular System Xylem tissue carries water and minerals upward from the roots Phloem tissue carries sugars made by photosynthesis from the leaves to where they will be stored or used Sap is the fluid carried inside the xylem or phloem copyright cmassengale

39 Nonvascular Plants Do not have vascular tissue for support or conduction of materials Called Bryophytes Require a constantly moist environment Sporophyte stage Gametophyte Stage Moss Gametophytes & Sporophytes copyright cmassengale

40 copyright cmassengale
Nonvascular Plants Plants can’t grow as tall Cells must be in direct contact with moisture Materials move by diffusion cell-to-cell Sperm must swim to egg through water droplets copyright cmassengale

41 copyright cmassengale
Nonvascular Plants Includes mosses (Bryophyta), liverworts (Hepatophyta), and hornworts (Antherophyta) Liverworts Hornworts copyright cmassengale

42 Main Parts of Vascular Plants
Shoots -Found above ground -Have leaves attached - Photosynthetic part of plant Roots -Found below ground -Absorb water & minerals -Anchor the plant copyright cmassengale

43 copyright cmassengale
Vascular Plants Also called Tracheophytes Subdivided into two groups -- Seedless vascular plants and Seed- bearing vascular plants Club Moss copyright cmassengale

44 copyright cmassengale
CFU copyright cmassengale

45 Seedless Vascular Plants
Includes club moss (Lycophyta), horsetails (Sphenophyta), whisk ferns (Psilophyta), and ferns (Pterophyta) Whisk ferns Horsetails copyright cmassengale

46 Seed-Producing Vascular Plants
Includes two groups – Gymnosperms and Angiosperms Gymnosperms have naked seeds in cones Angiosperms have flowers that produce seeds to attract pollinators and produce seeds copyright cmassengale

47 copyright cmassengale
Gymnosperms Coniferophyta are known as conifers Includes pine, cedar, spruce, and fir Cycadophyta – cycads Ginkgophyta - ginkgo Cycad Ginkgo copyright cmassengale

48 copyright cmassengale
Gymnosperms Contains the oldest living plant – Bristle cone pine Contains the tallest living plant – Sequoia or redwood copyright cmassengale

49 copyright cmassengale
Angiosperms Flowering plants Seeds are formed when an egg or ovule is fertilized by pollen in the ovary Ovary is within a flower Flower contains the male (stamen) and/or female (ovaries) parts of the plant Fruits are frequently produced from these ripened ovaries (help disperse seeds) copyright cmassengale

50 copyright cmassengale
Angiosperms Division Anthophyta Subdivided into two groups – Monocots and Dicots Monocots have a single seed cotyledon Dicots have two seed cotyledons copyright cmassengale

51 copyright cmassengale
Monocots Parallel venation in leaves Flower parts in multiples of 3 Vascular tissue scattered in cross section of stem copyright cmassengale

52 copyright cmassengale
Dicots Net venation in leaves Flower parts in multiples of 4 or 5 Vascular tissue in rings in cross section of stem copyright cmassengale

53 copyright cmassengale
Plant Uses copyright cmassengale

54 Why We Can’t do Without Plants!
Produce oxygen for the atmosphere Produce lumber for building Provide homes and food for many organisms Prevent erosion Used for food copyright cmassengale

55 More Reasons We Can’t do Without Plants!
Produce wood pulp for paper products Source of many medicines Ornamental and shade for yards Fibers such as cotton for fabric Dyes copyright cmassengale
