Science Chapter 2 How Cells Function
What is produced in photosynthesis?
O2, which is oxygen is produced in photosynthesis
What is the oxygen used for?
Oxygen is used for us to breathe
What is photosynthesis?
Photosynthesis is a process in which sunlight energy is used to make glucose.
Where does photosynthesis occur?
Photosynthesis occurs inside the chloroplast of a cell
What are some sources of CO2?
Some sources of CO2 are living organisms that exhale it, factory smokestakes, and car fumes.
What are the two main functions of chloroplasts?
The 2 main functions of the chloroplast are to produce food (glucose) and to store food energy.
Describe cellular respiration?
The breakdown of glucose molecules to release energy ;Takes place in all living things; Is a step by step process, takes place in mitochondria.
What type of energy does the plant use to convert CO2 and H20 into sugar?
The energy that a plant uses to convert CO2 and H2O into sugar is sunlight.
What is the primary pigment found in the chloroplast?
The primary pigment found in the chlorplast is chlorophyll.
What three things are used to make glucose in photosynthesis?
The three things that are used to make glucose are carbon, hydrogen, and oxygen.
Where does the water come from?
Water comes from ground
Where does the water enter the plant?
Water enters the plant at the roots
Why is what happens with the sugar during photosynthesis important to us?
We cannot make our own food (glucose, energy), we must get our food from plants. Plants are the first step in the food chain. The oxygen released during photosynthesis is necessary for all living things.
What is the formula for photosynthesis?
CO2 + H2O + sunlight-----C6H12O6 + O2
What is the glucose used for?
Glucose is used by the plant for energy and growth.
What are chloroplasts and where are they found?
Chloroplasts are an organelle found in leaves of a green plant.
Why do most leaves appear green?
Leaves appear green because chlorophyll absorbs most of the colors in the color spectrum, and reflects only green and yellow wavelengths of light.
What is the goal during photosynthesis?
Main goal of photosynthesis is to make sugar(glucose) for the plant to use as energy. Oxygen is also released in this reaction. as a biproduct.
