Wake-up 1. W hat are three components plant cells have that animal cells do not? 1.What are some general characteristics of plants?

Plant Anatomy and Physiology Watch Video

Plants By: Manuel Alvarado Use this PowerPoint to fill in the chart at the top of the notes.

Prokaryotic or Eukaryotic? Plants are Eukaryotic Eukaryotic means the organisms cells have a nucleus and other organelles.

Unicellular or multicellular? Plants are Multicellular Multicellular means that all plants are made up of more than one cell

Autotroph or Heterotroph? Plants are Autotrophs and get their own food through a process called photosynthesis Autotrophs are organisms that create their own food

Interesting Facts The bamboo is the fastest growing plant in the world growing to at least 3 meters in just one day

Interesting Facts Over 2000 plants are used by us to make food.

Interesting Facts Plant remains at the bottom of any large body of water can eventually turn into coal due to metamorphosis

Interesting Facts One bushel of corn can sweeten more than 400 cans of soda

Interesting Facts A pineapple is actually a berry

Examples Bamboo

Examples Tobacco Plant

Examples Venus Fly Trap

Examples Poison Ivy

Examples Cactus

Early Plant Ancestors: Green Algae

All were Aquatic

Stipe: Holds plant upright Rhizoid: Anchors algae Chloroplast Vacuole Cell Wall Green Algae Structure

Chloroplast VacuoleCell Wall True Roots Stem Leaf

Rhizoid: Anchors algae Put down Roots Algae Absorb the water they need from surrounding; rhizoids anchor What did plants have to do to make the move to land?

Put down Roots Plants Have roots which absorb water from soil

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

What did plants have to do to make the move to land? Develop a functional stem Plants Stem transports food and water throughout plant

Rhizoid: Anchors algae 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

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

What is the function of Roots?

Absorb water and nutrients for the plant. Structure and support

Two types of roots : Fibrous Many lateral roots branching from one main point

Two types of roots : Tap One main root; lateral roots extending from the tap root

What type of root? Fibrous

What type of root? Tap

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.

Plant tissue: Vascular Location: Core of the stem

Plant tissue: Vascular Function: Transports glucose and water throughout plants

Components of Vascular Tissue: Phloem Transports glucose down throughout the plant. Glucose is made in the leaves of a plant. “Phloem down below em”

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”

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

Leaf Structure Stem

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.

Net Parallel

Cuticle Found on the top side of leaves Waxy outer layer which prevents water from leaving the cell

Stomata Found on the underside of leaves They are tiny openings that allow water and gases to move in and out the leaf.

Stomata

Plant Tissue: Dermal Location: Outer most layer of tissue. Function: Prevent water loss and protection

Plant Tissue: Dermal Components: Cuticle Stomata

Plant Responses: PhototropismPhototropism Plants response to light. Leaves will bend toward the light to maximum photosynthesis. Click on “Phototropism” for short video. Do not need headphones

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

Thigmotropism Plants response to touch Click on “Thigmotropism” for short video. Do not need headphones

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)
