Cellular Respiration
True or False: Almost all living things use cellular respiration to get energy.
True
_____________________ is the process by which plants absorb sunlight to make sugar (food).
Photosynthesis
Name an organism that does not perform photosynthesis. __________________
butterfly, human, dog, cat, etc.
All living things are made of _________________.
carbon
Explain why the top of a leaf is different from the bottom of the leaf.
The top of a leaf is darker than the bottom of a leaf. The top of a leaf has more chloroplasts than the bottom of the leaf. The chloroplasts are an organelle that help capture energy from the Sun. The chloroplasts contain a green pigment called chlorophyll. More chloroplasts in top of the leaf also means more chlorophyll in the top of the leaf.
What is the purpose of cellular respiration?
The purpose of cellular respiration is to make usable energy.
The inputs of photosynthesis are ________________________________.
carbon dioxide, water, and energy from the Sun
________________ are organelles in plant cells that help carry out photosynthesis.
Chloroplasts
Plants release _________________ and take in ______________________.
oxygen; carbon dioxide
Explain how plants and people/animals rely on each other.
People and animals exhale carbon dioxide, which plants need. Plants take in the carbon dioxide and release oxygen, which the people and animals need.
What are the inputs of cellular respiration?
glucose and oxygen
The outputs of photosynthesis are _____________________.
glucose and oxygen
_________________ is a green pigment in plants that helps absorb sunlight to make energy.
Chlorophyll
People and animals release _________________ and take in ______________________.
carbon dioxide; oxygen
Explain the inputs and outputs of photosynthesis (Don’t just list the inputs and outputs).
The inputs of photosynthesis are energy from the sun, water and carbon dioxide. Chloroplasts in the top of the leaf help capture energy from the Sun. Water enters the plants through the roots. Carbon dioxide enters the plants through tiny openings called stomata.
The outputs of photosynthesis are glucose and oxygen. Energy is stored in the plant in the form of glucose. Oxygen is released from tiny openings in the plant leaves called stomata.
What are the outputs of cellular respiration?
carbon dioxide, water, and energy
The equations for cellular respiration and photosynthesis are ______________________
opposite
Most photosynthesis takes place in the _________________.
leaves
An increase in carbon being released into the atmosphere is contributing to _______________________.
climate change
Explain one path through the carbon and oxygen cycle.
A person eats a plant, which contains carbon. The carbon passes from the plant to the person. The person exhales and releases carbon into the atmosphere. Carbon from the atmosphere enters the plants.
Where does cellular respiration take place?
The mitochondria
The top of a leaf is ________________than the bottom of the leaf because there are more ____________________.
darker, chloroplasts
The _______________________ are tiny openings in the leaves of plants that allow for gas to be exchanged.
stomata
Carbon is released through ____________________ and ______________________.
volcanic activity; human activity
Carbon is stored in _______________, _______________, and _____________________.
oceans, soils, and fossil fuels
