Wake-up How are Fungus plant-like? How are Fungus animal-like?
Explain how Fungus obtain nutrients.

3
Use this PowerPoint to fill in the chart at the top of the notes.
This is also an example of the Kingdom Project that is due tomorrow at 8am. Plants
4
Prokaryotic or Eukaryotic?
Plants are Eukaryotic Eukaryotic means the organisms cells have a nucleus and other organelles.
5
Unicellular or multicellular?
Plants are Multicellular Multicellular means that all plants are made up of more than one cell
6
Autotroph or Heterotroph?
Plants are Autotrophs and get their own food through a process called photosynthesis Autotrophs are organisms that create their own food
7
Interesting Facts The bamboo is the fastest growing plant in the world growing to at least 3 meters in just one day
8
Interesting Facts Over 2000 plants are used by us to make food.
9
Interesting Facts Plant remains at the bottom of any large body of water can eventually turn into coal due to metamorphosis
10
Interesting Facts One bushel of corn can sweeten more than 400 cans of soda
11
Interesting Facts A pineapple is actually a berry
12
Examples Bamboo
13
Examples Tobacco Plant
14
Examples Venus Fly Trap
15
Examples Poison Ivy
16
Examples Cactus
17
Early Plant Ancestors: Green Algae
18
All were Aquatic
19
Green Algae Structure Stipe: Holds plant upright Chloroplast Cell Wall
Vacuole Rhizoid: Anchors algae
20
Chloroplast Stem Cell Wall Vacuole Leaf True Roots
21
What did plants have to do to make the move to land?
Put down Roots Algae Absorb the water they need from surrounding; rhizoids anchor Rhizoid: Anchors algae
22
What did plants have to do to make the move to land?
Put down Roots Plants Have roots which absorb water from soil
23
What did plants have to to make the move to land?
Develop a functional stem Algae Absorb what they need from their surroundings; Water holds them upright
24
What did plants have to do to make the move to land?
Develop a functional stem Plants Stem transports food and water throughout plant
25
What did plants have to do to make the move to land?
Prevent Water Loss Algae Live in water; no need to control water; absorb what they need Rhizoid: Anchors algae
26
What did plants have to do to make the move to land?
Prevent water loss Plants Developed a waxy outer layer to keep water inside
27
What is the function of Roots?
28
What is the function of Roots?
Absorb water and nutrients for the plant. Structure and support
29
Two types of roots: Fibrous
Many lateral roots branching from one main point
30
One main root; lateral roots extending from the tap root
Two types of roots: Tap One main root; lateral roots extending from the tap root
31
What type of root? Fibrous
32
What type of root? Tap
33
What is the function of stems?
34
What is the function of stems?
Stems are the main highway for the transport of glucose and water. Vascular tissue makes up core of stems.
35
Plant tissue: Vascular
Location: Core of the stem
36
Plant tissue: Vascular
Function: Transports glucose and water throughout plants
37
Components of Vascular Tissue: Phloem
Transports glucose down throughout the plant. Glucose is made in the leaves of a plant. “Phloem down below em”
38
Components of Vascular Tissue: Xylem
Vascular tissue is used to transport materials throughout the plant. Xylem transports water up throughout the plant “Xylem to the skylem”
39
What is the function of leaves?
40
What is the function of leaves?
Leaves are the site of photosynthesis. Photosynthesis is the process in which plants capture energy from the sun and carbon dioxide to make glucose
41
Leaf Structure Stem
42
Leaf Venation: Net venation: veins are spread out on the blade in a net. Like the network of veins in our bodies. Parallel venation: veins are lined side by side (parallel) on the blade.
43
Parallel Net
44
Cuticle Found on the top side of leaves
Waxy outer layer which prevents water from leaving the cell
45
Found on the underside of leaves
Stomata Found on the underside of leaves They are tiny openings that allow water and gases to move in and out the leaf.
46
Stomata
47
Outer most layer of tissue. Prevent water loss and protection
Plant Tissue: Dermal Location: Outer most layer of tissue. Function: Prevent water loss and protection
48
Plant Tissue: Dermal Components: Cuticle Stomata
49
Plant Responses: Phototropism
Plants response to light. Leaves will bend toward the light to maximum photosynthesis. Click on “Phototropism” for short video. Do not need headphones
50
Gravitropism Plants response to gravity
Positive Gravitropism: Roots grow down Negative Gravitropism: Stems grow against gravity Click on “Gravitropism” for short video. Do not need headphones
51
Plants response to touch
Thigmotropism Plants response to touch Click on “Thigmotropism” for short video. Do not need headphones
52
Plant Diagram Activity
Read and following the directions on the Plant Diagram sheet. In picking out a plant, feel free to use anything and a young, responsible student would use. You can Google, “Clip Art Plants” to help you out. Make sure that it has roots, stems, and leaves. (No Cacti)
