What is photosynthesis?
Photosynthesis is the process by which plants make their own food.
Where does photosynthesis primarily take place in plants?
Photosynthesis primarily takes place in the leaves of the plant.
What are the three main things required for photosynthesis?
Sunlight, water, and carbon dioxide.
What special structures do plant leaves have for photosynthesis?
Plant leaves have chloroplasts, which contain a green pigment called chlorophyll.
What is the role of chlorophyll in photosynthesis?
Chlorophyll captures sunlight and converts it into energy for the plant.
How is water transported to the leaves during photosynthesis?
Water is absorbed by the plant’s roots and transported to the leaves through tubes called xylem.
How does carbon dioxide enter the plant?
Carbon dioxide is taken in through tiny pores called stomata on the leaf’s surface.
What is produced as a result of the chemical reaction in photosynthesis?
The production of glucose (a type of sugar) and oxygen as byproducts.
Why is oxygen important for living organisms?
Oxygen is essential for the survival of many living organisms, including humans.
How is glucose used by the plant?
Glucose is used as a source of energy for growth, reproduction, and other vital functions.
What is a food chain?
A food chain shows how living things get their food, starting with plants and ending with decomposers.
What is a food web?
A food web is a connection of multiple food chains and follows multiple paths.
What do food chains usually start with?
Food chains usually start with plants that make their food using sunlight, water, and carbon dioxide.
What are consumers in a food chain?
Consumers are organisms that cannot produce their food and rely on other organisms for energy.
What are the three main types of consumers?
Herbivores (primary consumers), carnivores (secondary and tertiary consumers), and omnivores (consumers that eat both plants and animals).
What role do decomposers play in a food chain?
Decomposers break down dead plants and animals, returning nutrients to the soil for plants to use again.
Can you name some examples of decomposers?
Bacteria, fungi, earthworms, and millipedes are examples of decomposers.
What are the four chambers of the heart?
Right atrium, right ventricle, left atrium, and left ventricle.
Where does deoxygenated blood enter the heart?
The right atrium.
Where does the right ventricle pump blood?
To the lungs.
Where does oxygenated blood enter the heart?
The left atrium.
What is the strongest chamber of the heart?
The left ventricle.
The left ventricle.
Between the right atrium and right ventricle.
Where is the pulmonary valve located?
Between the right ventricle and pulmonary artery.
