Happy Wednesday! Bellwork: February 25 In your own words DEFINE the word “Tropism”. Give examples of what the following four tropisms may look like in a plant’s “real life” (remember the video from Monday) Gravitropism (+/-), Hydrotropism, Phototropism, Thigmotropism

GradeInfo Notutorials today! Iwill take work untilFriday afternoon You’ll have a plant testMonday The plant system interaction homework will countfor nextgrading term

Anticipation Thoughts…(true or false?) 1.Thigmotropism is a plant’s response to gravity. 2.Plants breathe 3.Plants need oxygen to survive 4.Singing helps plants grow 5.Plants produce glucose during photosynthesis.

Cellular Energy Essential Question: How are photosynthesis and cellular respiration related?

How is energy transformed in living organisms?

Energy :the ability to do work

Most energy comes from the sun in the form of light.

All energy that is not used by organisms leaves the Earth in the form of heat.

Adenosine triphosphate (ATP) is the chemical that cells use to store and release energy. The energy in ATP is stored in the bonds between the elements.

How do plants make their own food?

To perform photosynthesis, plants need: 1. sunlight (energy source) 2. water 3. carbon dioxide These are called the reactants.

After photosynthesis, the plant has produced: 1.Glucose (molecule that the plant uses to produce energy) 2.Oxygen (given off through the leaves) These are called the products. Draw this picture

SUNLIGHT The equation of photosynthesis is: 6CO 2 + 6H 2 O + sunlight  C 6 H O 2 carbon dioxide + water + energy  glucose + oxygen

Talk to your partner: Where do plants take in carbon dioxide? Where do plants take in water?

Photosynthesis occurs in an organelle in the leaves. Chloroplasts: organelle where photosynthesis takes place Chlorophyll: pigment in chloroplasts, makes plants green

How do animals get energy for living?

Cellular respiration: the process that releases energy (ATP) by breaking down glucose.

Cellular respiration occurs in the mitochondria of plant and animal cells. Cellular respiration makes 36 ATP molecules The remaining energy is lost as heat. Mitochondria

Talk to you partner: If humans do not make our own food in photosynthesis, how do we get nutrients to perform cellular respiration?

The formula for cellular respiration is: 6O 2 + C 6 H 12 O 6  6CO 2 + 6H 2 O + Energy oxygen + glucose  carbon dioxide + water + ATP Cellular respiration requires oxygen and glucose and gives off carbon dioxide, water, and energy.

Draw this

Debrief: Explain the relationship between cellular respiration and photosynthesis in terms of matter. What about energy?

Let’s Race! I’m giving you a set of manipulatives. When I say “products of photosynthesis” for example. The first table to correctly build it earns a point. EACH person must be correct! Table that earns the most points wins (at life)!!
