(47 cards)
Tiny pores found in leaves and stems that allow the exchange of gases?
Stomata
The food-making process in green plants that use sunlight?
Photosynthesis
A group of chemical compounds made from carbon, oxygen, and hydrogen?
Carbohydrate
The process in which energy is released from food (sugar) inside a cell?
Cellular Respiration
What do all living things need to survive?
Energy
Where do plants get their energy to make their own food?
From sunlight
Where does photosynthesis occur?
In cells that have chloroplasts
What are needed to perform photosynthesis?
Sunlight, water and carbon dioxide.
- What strikes a green part of the plant, such as a leaf?
Sunlight
**2. What captures the sunlight energy which powers photosynthesis?
Chlorophyll
- Where are water and carbon dioxide combined to make food in the form of sugars?
Inside the chloroplasts
- Where do the sugars produced in the leaf during photosynthesis go?
They go into the leaf’s veins and from there to all parts of the plant.
- What is the produced as a waste product of photosynthesis?
Oxygen
*****Why are the leaves important for photosynthesis?
They capture the sunlight
Where do the leaves get water?
From the roots
What is the tissue called that carries the water to the leaves of the plant?
Xylem
What is the function of the stomata?
They open and close to let in and give off the gases carbon dioxide and oxygen.
Who does the job of opening and closing the stomata when needed belong?
The two guard cells that surround them
Where are the chloroplasts of the cells located?
Underneath the epidermis
What is the outermost layer of the leaf?
Epidermis
Inside the chloroplasts, what is combined in the presence of light energy and makes what?
Carbon dioxide and water combine to make sugars and oxygen
What are the tissues that transport the sugars to all of the plant’s cells called?
Phloem
What are excess sugars stored as in the plant?
Starch
During photosynthesis, plants produce sugar in the form of what?
Carbohydrate
