What is the most efficient way for cells to harvest energy?
Cellular Respiration
100
What is light energy converted to in photosynthesis?
Chemical energy
100
Why is photosynthesis vital for plants?
gives oxygen, etc.
100
Cellular respiration occur in which cells, eukaryotic or prokaryotic?
both
100
What is the epidermis?
The visible surface of the leaf.
200
What is the energy converted into?
ATP.
200
Chemical energy can be later release to ____ the organism's acitvities.
fuel.
200
Where does cellular respiration take place?
In a cell's mitochondria.
200
What is the plants food called, and what is made out of?
Glucose; sunlight, water, carbon dioxide, soil
200
What are some differences between the lower and upper epidermis?
Lower epidermis has holes, (stomata)
300
What is cellular respiration?
The most efficient way for cells to harvest energy stored in food is through cellular respiration, a catabolic pathway for the production of adenosine triphosphate (ATP).
300
What is photosynthesis?
Photosynthesis is a process used by plants and other organisms to convert light energy, normally from the sun, into chemical energy that can be later released to fuel the organisms' activities.

Name at least 2 things used in Cellular respiration Ex. Carbohydrates.
carbohydrates, fats, glucose, and proteins
300
What is the difference between the Xylem and the Phloem?
Xylem- tubes that bring water from the roots. Phloem- Transportation of food and nutrients such as sugar from leaves to storage organs and growing parts of plant, moves up or down.

What gives the leaf strength and protection?
pith,
400
Name the second stage of cellular respiration, and what happens during that stage.
The Citric Acid Cycle begins after the two molecules produced in glycolysis are converted to a slightly different compound. Through a series of intermediate steps, several compounds capable of storing "high energy" electrons are produced along with two ATP molecules. The Citric Acid Cycle occurs only when oxygen is present but it doesn't use oxygen directly.
400
The outcome of photosynthesis creates?
Glucose and oxygen.
400
The guard cell protects the ________ and controls the ________________.
stomata, epidermis openings
400
What is the first step of photosynthesis?
First the chlorophyll traps the sunlight in the leaves, creates energy for the plants.
400
Where is the chlorophyll stored, what is special about the chlorophyll?
chloroplast, gives leaf its green color.

Name all three stages, and what happens in those stages.
Glycolysis: Glycolysis means "splitting sugars." Glucose is split into two molecules. In the process, two molecules of ATP, two molecules of pyruvic acid and two electron are produced. Glycolysis can occur with or without oxygen. In the presence of oxygen, glycolysis is the first stage of cellular respiration. Without oxygen, glycolysis allows cells to make small amounts of ATP. The Citric Acid Cycle: The Citric Acid Cycle begins after the two molecules produced in glycolysis are converted to a slightly different compound. Through a series of intermediate steps, several compounds capable of storing "high energy" electrons are produced along with two ATP molecules. The Citric Acid Cycle occurs only when oxygen is present but it doesn't use oxygen directly. Electron Transport: Electron Transport requires oxygen directly. The electron transport "chain" is a series of electrons in the membrane of the mitochondria in eukaryotic cells. Through a series of reactions, the "high energy" electrons are passed to oxygen. In the process ATP is formed.

What is the photosynthesis equation?
6h2O+6cO2=c6h12o6+6O2

What does ATP stand for?
adenosine triphosphate

Explain the 4 steps of photosynthesis.
1.) First the chlorophyll traps the sunlight in the leaves, creates energy for the plants. 2.) Next the sunlight gives the plant energy to start the food-making process. 3.)The roots suck nutrients up to the leaves and then the leaves mix carbon dioxide, the nutrients and water to make their food(glucose). 4.)Finally waste is removed from the plant, it is called oxygen.

Name all the leaf parts and their functions There are 9 in all.
Cuticle - prevent water loss, transparent waxy surface Upper Epidermis- visible surface. Lower Epidermis- visible surface, holes called stomata Chloroplast – chrollypll, makes the leaf green, stored here Stomata- where carbon dioxide and co2 go in and out. Guard Cell- protect stomata, controls epidermis openings. Pith- wraps around for strength and protection Xylem- tubes that bring water from the roots. Phloem- Transportation of food and nutrients such as sugar from leaves to storage organs and growing parts of plant, moves up or down. Chloroplast – chrollypll, makes the leaf green, stored here
