Photosynthesis Transforms Radiant Energy Chemical Energy Water + Carbon Dioxide sunlight Glucose (sugar) + Oxygen H 2 O + CO 2 C 6 H 12 O 6 + O 2 Happens in Plants Leaf Chloroplast
RadiantEnergy AKA… –Light Energy –Solar Energy Energy given off by the Sun ALL energy on Earth originated from the Sun
Chemical Energy Result of photosynthesis Energy transformed in plants Plants and animals use this energy to move and grow
Chemical Equation Summary of what happens in a chemical reaction Identifies elements involved and # atoms of each Includes…. Reactants Products Example:
Chemical Formula Summarizes what a substance is made of (elements & # atoms of each) Example: H 2 O Water is made of… –2 atoms of Hydrogen (2 is a subscript) –1 atom of Oxygen
Reactants Substance(s) that exist before a chemical reaction Usually listed first in a chemical equation Example: H 2 O + CO 2 C 6 H 12 O 6 + O 2
Products Substance(s) that are the result of a chemical equation Usually listed last Example: H 2 O + CO 2 C 6 H 12 O 6 + O 2
Chloroplast Site of photosynthesis Organelle found in a plant cells Contains chlorophyll
Chlorophyll Pigment that makes leaves green Responsible for capturing sunlight
Stomata Pores on a plant that allow gas exchange for photosynthesis …. –Carbon Dioxide (CO 2 ) enters –Oxygen (O 2 ) exits –Water (H 2 O) exits during transpiration Mostly found on leaves
Pistil Female reproductive organ in a flower Where seeds are developed Can be 1 or multiple in a flower
Stamen Male reproductive organ of a flower Covered with pollen on the ends
Xylem Transport system Moves water and some nutrients from Roots rest of plant New xylem are made each year on the outside of a plant (only lives 1 year)
Phloem Transport system Moves Glucose/Sugar from chloroplast rest of plant Phloem….photosynthesis
Homeostasis Process of an organism maintaining balance Things that need to be balanced…water, temperature
Stimulus Cause Happens 1 st Types of Stimuli –External (outside) –Internal (internal) The SUN is an example of an external stimuli
Response Effect Reaction Happens 2 nd The plant’s growth toward the light
Tropism Plant growth response to stimuli –Common stimuli are light, gravity, water
Phototropism Plant’s response to light Photo = Light
Geotropism / Gravitropism Plant’s growth response to gravity –Positive grows TOWARD –Negative grows AWAY Geo = Earth
Hydrotropism Response of a plant’s roots to water Hydro = Water
Turgor Pressure Force of water pushing on a plant cell’s vacuole A – sufficient (plenty) water to make plant stand upright (stiff, rigid) B – insufficient (lacking) water, the plant wilts or bends
Emergence of a Seedling Seed sprouting out of the ground Requires an unbalanced force that results in motion Sometimes called germination
Flower Leaf Stem Root
Petal Pistil – female organ Stamen – male organ Where seeds are produced Where pollen is produced
Photosynthesis Big Ideas. 7.5A Recognize that radiant energy from the Sun is transformed into chemical energy through the process of photosynthesis I.
Photosynthesis, Respiration and Transpiration SC Standard Original PowerPoint is from teachers.greenville.k12.sc.us.
Tropisms. Stimulus Change in an organism’s surroundings that causes a response –Internal (chemicals and hormones) –External (light, touch, water, gravity)
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.
1. Identify the raw materials of photosynthesis. carbon dioxide water 2. What is the energy source needed for photosynthesis to occur? sunlight 3. Identify.
BELLWORK: Copy the bold portion of the question and write your entire answer: HAPPY TUESDAY During transpiration, water moves through a plant and out into.
PLANTS The plant kingdom is divided into both non-vascular and vascular plants.
Draw this in your notes:. Most energy transformations can be traced back to the sun: the original source of energy for life on earth. Energy Transformations.

KINGDOM PLANTAE Think of three ways a plant cell is different from an animal cell.
Plants!. Chloroplast: organelle Chlorophyll: green pigment Pigment: substance that reflects some light and absorbs the rest.
Chapter 13 Plant Processes. Section 1: Objectives Describe photosynthesis. Compare photosynthesis and cellular respiration. Describe how gas is exchanged.
Plants People and animals need oxygen to live. Green plants make the oxygen in the air we breathe. How do plants make oxygen? Plants take in carbon dioxide.
Roots: Anchors plant by keeping it firmly in place. Absorbs water and minerals. Stem: Holds up the plant. Transports water, minerals, and.
