    1. Standard 10 a. By: Brandi and Jamaal

    2. All About Plants Plants are multicellular eukaryotes that have cell walls made of cellulose. Plants are in the Kingdom Plantae Plants are autotrophs ( they make their own food)

    3. Roots- help to anchor the plant in the soil so it doesn’t fall over Stems- support the plant; act as the plants pluming system by conducting water and nutrients from the roots and food in the form of glucose from the leaves to other plant parts Leaves- designed to capture sunlight which they use to make food through photosynthesis Photosynthesis- they use the energy from sunlight to produce glucose Flowers- the reproductive part of most plants Seeds- an embryo of a plant that is encased in a protective covering and surrounded by food supply

    4. Vascular & Nonvascular Plants Vascular refers to the tubes or vessels that water travels through from the roots to the stems & leaves. Nonvascular plants do NOT have these tubes. Most of the plants in this group are small, low to the ground. Vascular plants do have these tubes to carry the water & nutrients & can grow very tall

    5. Vascular & Nonvascular Plant Comparison

    6. Vascular Plants are divided into 2 Groups by the way they reproduce Gymnosperms ( means “Naked Seeds”) are the trees that have cones.Their seeds are not covered with a fruit so we say they are naked. Angiosperms are trees & plants that have flowers & fruits.

    7. Gymnosperm & Angiosperm Comparison

    8. Parts of a Flower Stamen- (it has the word Men in the word) the male part of the flower and they produce a sticky powder pollen Pistil- the female part of the body; Stigma- the top part of the pistil which is often sticky Ovule- the base of the pistil where seeds are made Petals – attract the insects with color & scent but they do NOT have a reproductive function

    9. Pollination Angiosperms are pollinated by insects The flowers are often bright colored and have a strong smell to attract the pollinators Gymnosperms are pollinated by wind . The wind picks up pollen from one pine tree and carries it to another.

    10. Monocots and Dicots Two classes within the angiosperms: the monocots, and dicots. Monocots and dicots are named for the number of seed leaves, or cotyledons, in the plant embryo ( in other words, how many leaves come out of the ground when the plant first sprouts) Monocots have one seed leaf Dicots have two seed leaves

    11. Cotyledons Cotyledon- the first leaf or the first pair of leaves produced by the embryo of a seed plant

    12. Monocot & Dicot Comparison

    13. Venation Patterns

    15. Question 1 Which student has correctly classified each plant?

    16. Answer… D.STUDENT 4

    17. Question 2 A class observes an unknown plant and discovers that the plant’s seeds have only one cotyledon. When the class examines the leaves and the stem, what will they MOST LIKELY find? A parallel veins and a ring of vascular bundles B parallel veins and scattered vascular bundles C a netted arrangement of veins and a ring of vascular bundles D a netted arrangement of veins and scattered vascular bundles

    18. Answer… B. Parallel veins and scattered vascular bundles

    19. Question 3 Why are nonvascular plants typically smaller and shorter than vascular plants? A Nonvascular plants use mitosis to produce cells. B Nonvascular plants use photosynthesis to obtain energy. C Nonvascular plants lack tubes to transport materials. D Nonvascular plants lack deep fibrous roots to obtain water.

    20. Answer… C. Nonvascular plants lack tubes to transport materials

    21. Question 4 Study the table below. Which statement is correct?

    22. Answer… C. Plant 1 is a monocot, and plant 2 is a dicot

    23. Question 5 Study the leaf below. A plant with the leaf- venation pattern shown would be classified a

    24. Answer… DICOT Dicots have netted venation

    25. Question 7 What kingdom are plants in? The flower kingdom Kingdom Plantae Kingdom Fungi Kingdom Animalia

    26. Answer B. Kingdom Plantae

    27. Question 9 What is the first leaf or the first pair of leaves produced by the embryo or seed plant? Dicot Gametophyte Monocot Cotyledon

    28. Answer D. cotyledon

    29. Question 10 Which has a single cotyledon? Sporophyte Monocots Fuit dicots

    30. Answer B. Monocots Mono means single or one

    31. Question 12 What are plants considered? Autotrophs Monotrophs Hetertrophs green

    32. Answer A. autotrophs

    33. Question 13 Do plants have eukaryotic or prokaryotic cells? Hint: Prokaryotic cells are very primitive & do not have true organelles. Eukarytotic cells are “true cells”

    34. Answer Eukaryotes Only bacteria are Prokaryotic cells. All others are made up of True cells
