13.1a Photosynthesis Flashcards
What do all organisms need to grow and survive?
Food
What does food provide for growth and energy?
Raw materials
What process do plants go through to get their own food and survive?
Photosynthesis
Plants make their own food and provide many other organisms with raw materials for growth and energy. What are plants known as relating to the food chain?
Producers
Why are plants essential for life on Earth
Plants provide many other organisms with raw materials, if there were no plants, the animals that depended on plants would perish, leaving us with no food or oxygen
What type of food do plants create?
Sugars
Which organ in the plant does photosynthesis take place?
In the leaves
What catalyzes the chemical reaction that takes place during photosynthesis?
Light energy
What is the word equation for photosynthesis
Carbon Dioxide + Water -> Glucose + Oxygen
How do plants create their own food via photosynthesis
Chlorophyll absorbs light energy form the Sun to convert carbon dioxide and water into glucose and the bi-product, oxygen
What is the name of part labelled 1 of a plant cell?
Cytoplasm
What is the name of part labelled 2 of a plant cell?
Nucleus
What is the name of part labelled 3 of a plant cell?
Cell Membrane
What is the name of part labelled 4 of a plant cell?
Mitochondria
What is the name of part labelled 5 of a plant cell?
Cell Wall$
What is the name of part labelled 6 of a plant cell?
Vacuole
What is the name of part labelled 7 of a plant cell?
Chloroplasts ( A green pigment ), this is what gives the leaves their color
What is the function of the cytoplasm in a plant cell?
An area where chemical reactions take place
What is the function of the nucleus in a plant cell?
Control what happens in the cell and stores information
What is the function of the cell membrane in a plant cell?
Controls what goes in and out of the plant cell
What is the function of the vacuole in a plant cell?
Contains cell sap and supports the plant cell
What is the function of the cell wall in a plant cell?
Made of cellulose which strengthens the cell
What is the function of the chloroplasts in a plant cell?
Contain chlorophyll which helps trap and absorb sunlight for photosynthesis.
What is the name of part labelled 1 of a plant cross-section?
Waxy Cuticle
What is the name of part labelled 2 of a plant cross-section?
Upper Epidermis
What is the name of part labelled 3 of a plant cross-section?
Palisade Mesophyll Cells
What is the name of part labelled 4 of a plant cross-section?
Spongy Mesophyll Cells
What is the name of part labelled 5 of a plant cross-section?
Lower Epidermis
What is the name of part labelled 6 of a plant cross-section?
Stomata (Stoma Singular)
What is the name of part labelled 7 of a plant cross-section?
Guard Cells
What is the name of part labelled 8 of a plant cross-section?
Air Spaces
What is the name of part labelled 9 of a plant cross-section?
Phloem Tubes
What is the name of part labelled 10 of a plant cross-section?
Xylem vessels
What is the function of the waxy cuticle of a plant cross-section?
Prevents water loss
What is the function of the upper epidermis of a plant cross-section?
Provides Protection
What is the function of the palisade mesophyll cells of a plant cross-section?
Where photosynthesis takes place, contains a lot of chloroplasts
What is the function of the spongy mesophyll cells of a plant cross-section?
Where photosynthesis takes place, contains just a few chloroplasts
What is the function of the lower epidermis of a plant cross-section?
Provides Protection
What is the function of the guard cell of a plant cross-section?
Opens and closes the stomata for gas exchange
What is the function of the stomata of a plant cross-section?
Pores in the leaf to allow gas exchange
What is the function of the air spaces of a plant cross-section?
Spaces In the leaf to allow gas exchange
What is the function of the Phloem tubes of a plant cross-section?
Transports sucrose and amino acids
What is the function of the xylem vessels of a plant cross-section?
Transports water and minerals ions
What 3 organelles do plant cells and animal cells have in common?
Cell membrane, nucleus, and cytoplasm
What 3 organelles do only plant cells have compared to animal cells?
Cell wall, chloroplasts, and vacuole
What color/s of light do leaves absorb?
Red and blue light
What color/s of light do leaves reflect?
Green light
What 4 things are needed for photosynthesis?
Carbon dioxide, water, sunlight, and chlorophyll
How to plants make chlorophyll
They use magnesium from the soil
What do plants use glucose for?
Respiration, make new chemicals, and storage
When there is excess glucose, it is converted into starch and stored for later, how do we test for the presents of starch?
We use Iodine solution. If starch is present, the solution will turn blue/black. If starch is absent, it will remain orange/brown
