Wake-up 1.Are fungus autotrophs or heterotrophs? 2.Explain how they obtain their food? 3.Explain the relationship between mycelium and hyphae.
Plant Anatomy and Physiology
Early Plant Ancestors
All were Aquatic
Phytoplankton: Green Algae Unicelluar; Multicellular; Colonial (many individual organisms living together in a outer membrane)
Most diverse group of protists; can be found everywhere
Even on the backs of some animals
Stipe: Holds plant upright Rhizoid: Anchors algae Chloroplast Vacuole Cell Wall Green Algae Structure
Chloroplast VacuoleCell Wall True Roots Stem Leaf
What did plants have to do to make the move to land? Put down Roots
Stipe: Holds plant upright Rhizoid: Anchors algae Green Algae Structure Algae absorb the water they need from surrounding; rhizoids anchor
What did plants have to do to make the move to land? Develop a functional stem
Stipe: Holds plant upright Rhizoid: Anchors algae Green Algae Structure Algae absorb what they need from their surroundings; Water holds them upright
What did plants have to do to make the move to land? Prevent water loss
Stipe: Holds plant upright Rhizoid: Anchors algae Green Algae Structure Algae live in water; no need to control water; absorb what they need
What is the function of Roots?
Absorb water and nutrients throughout 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 “Phloem down below em” Transports glucose down throughout the plant. Glucose is made in the leaves of a plant.
Components of Vascular Tissue: Xylem “Xylem to the skylem” Vascular tissue is used to transport materials throughout the plant. Xylem transports water up throughout the plant
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.
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.
Plant Tissue: Dermal Location: Outer most layer of tissue. Function: Prevent water loss and protection
Plant Responses: Phototropism* Plants response to light. Leaves will bend toward the light to maximum photosynthesis.
Gravitropism Plants response to gravity Positive Gravitropism: Roots grow down Negative Gravitropism: Stems grow against gravity
Thigmotropism Plants response to touch Life: Plants 4:00
Plant Anatomy and Physiology. Early Plant Ancestors.
DO NOW 1.Put your protist lab & virtual pond in the bin 2.Get out your protist HW 3.What are the two main types of Protista?
Wake-up 1. W hat are three components plant cells have that animal cells do not? 1.What are some general characteristics of plants?
But where does the energy come from???? Parts of a Plant An Introduction to Photosynthesis.
KINGDOM PLANTAE What is a Plant? Multicellular and Eukaryotic.
Parts Of Plant – Photosynthesis Materials Needed by Plants for Photosynthesis: Water, Carbon Dioxide CO 2, and Sunlight. Materials Released by Plants in.
Plant Structures Roots, Stems, and Leaves Chapter 23.
Plant Cells and Tissues Chapter Plants are composed of cells which contain: –Cell wall –Central vacuole –Chloroplasts.
Chapter 23 Roots 23:2. 1.Roots – anchors plant into the ground and transports materials to the plants body A.2 types 1.Tap – primary root that grows long.
Plants?? What are Plants? Plants are multi-cellular living organisms that are able to use sun light & water to make their own food.
3/26 Get out: Plant Book Reminder: Test Corrections before/after school.
Plants as Living Organisms Plant Parts and Their Functions Plant and Soil Science Topic 2014.
Plants Common Characteristics. Characteristics Multicellular Multicellular More than one cell More than one cell Cell Wall Cell Wall Made of cellulose.
Part 3 Roots, Stems & Leaves Structure of Plants The structure of a plant contains a shoot system and a root system.
What is a plant? Nearly all plants are autotrophs, meaning they make their own food. They are also called producers. All plants are eukaryotes. All.
Specialized Tissues in Plants Plant Organs: Roots, Stems, and Leaves Roots Anchor the plant and absorb nutrients and water Mutualistic relationship with.
Plant Adaptations How do plants survive? What are some adaptations plants have made to aid in their survival?
1. Identify the raw materials of photosynthesis. carbon dioxide water 2. What is the energy source needed for photosynthesis to occur? sunlight 3. Identify.
PLANTS The plant kingdom is divided into both non-vascular and vascular plants.
What is a Plant? Plants are multicellular, autotrophic, organisms that have cell walls made of cellulose. They also contain chloroplasts used to absorb.
Plants. What is a Plant? Multicellular eukaryotes that have cell walls made of cellulose They develop from multicellular embryos and carry out photosynthesis.
Life of Plants Akar khoschnau. People know that the most basic things needed for a seed to germinate and become a sprout is sunlight, oxygen, water, and.
Photosynthesis & Cellular Respiration. Characteristics of Plant Cells Cell wall Large vacuole for water storage Contain Chloroplast (carry out photosynthesis!)
The Plant Kingdom Chapter 4:1 and 2 (Photosynthesis)
Plant Notes:. Plants: Multicellular eukaryotes Cell walls of cellulose Autotrophic (photosynthesis) Carbon dioxide + water + light Oxygen + glucose.
Plant Structure & Function. Monocots & Dicots Angiosperms are the class of plants that produce flowers. They can be broken down into two main groups –
Leaves. Above ground plant organ used to capture sunlight for photosynthesis Typically flat and thin to allow light to penetrate fully into the tissues.
Characteristics of the Plant Kingdom 1.Plants can make their own food; they are autotrophs you know! 2. Plants have many cells with walls; we call them.

Review of Plants for Quiz. KINGDOM PLANTAE Plants evolved about 500 million years ago from simple green algae that lived in the ocean. All plants are.
Introduction to Plants Chapter 22.1 Basic Plant Structure.
Plant Tissues. Cells of a vascular plant are organized into different tissues and organs Three major organs are: roots, stems, and leaves Dermal tissue.
Plants!!! What Domain? What kingdom? Eukaryotic or Prokaryotic? Autotroph or Heterotroph? Multicellular or Unicellular?
Plant structures What does a plant need for photosynthesis?
1. Plants are autotrophs- using chlorophyll for Photosynthesis 6CO 2 + 6H 2 O → C 6 H 12 O 6 + 6O 2 (Carbon dioxide and water makes glucose and oxygen)
PLANT TISSUES. 1) Dermal Tissue Form outermost layer of plant (like the skin) Protects plant Allows substances in and out through the stomata (will.
Leaf Structure. Function of Leaves To carry out photosynthesis.
What surrounds the stomata in a plant leaf that allows water, oxygen and carbon dioxide to enter and leave? Guard Cells 1.

Plants. Plant Organs Roots – Support a plant – Anchor it to the ground – Store food – Absorb water – Dissolve nutrients from soil Stems – Provide support.
Bellwork: Label the parts of the flower

What is a vascular plant? They have vascular tissue = a transport system Think back to that big tree. Plants are living. Just like you, they need water.
Roots, Stems and Leaves Chapter 23 Biology – Miller Levine.
KINGDOM PLANTAE Think of three ways a plant cell is different from an animal cell.
Plant Diversity Botany = the study of plants. General Plant Charactertistics ●Living things that have roots, stems, and leaves ~ some have flowers ●Eukaryotes.
