Vocab
The process by which plants and some other organisms use sunlight, carbon dioxide, and water to make food (glucose) and release oxygen.
Photosynthesis
An organism that makes its own food
Autotroph
T/F - When muscle cells run low on oxygen, lactic acid fermentation occurs
True
The final stage of the cell cycle, during which the cytoplasm divides, is called...
cytokinesis
The regular cycle of growth and division that cells undergo is called....
the cell cycle
The process by which cells break down glucose and oxygen to release energy (ATP), along with carbon dioxide and water.
Respiration
The main pigment for photosynthesis is chloroplasts
chlorophyll
T/F - The raw materials for respiration are the opposite of the end products for photosynthesis
False; same as
During which stage of the cell cycle down replication occur?
interphase
Almost all living things rely on the process of __________ to supply them with the energy they need
photosynthesis
A way cells release energy without using oxygen; it happens when oxygen is not available (for example, in muscles during intense exercise).
Fermentation
What are the products of photosynthesis?
Oxygen and Sugars
What happens during respiration?
Glucose is broken down, releasing energy
Mitosis is the stage of the cell cycle during which...
the cell's nucleus divides into two new nuclei
Carbon Dioxide enters plants through...
the stomata
Organelles found in plant cells where photosynthesis takes place; they contain the green pigment chlorophyll.
Chloroplasts
Give an example of how energy from the sun gets into your cells
Ms. Cobb's discretion
What are the products of respiration?
water & carbon dioxide
What does a centromere do?
holds the two chromatids of a chromosome together
which are the raw materials for respiration?
glucose and oxygen
Small openings on the underside of leaves that allow gases (such as carbon dioxide and oxygen) to enter and leave the plant.
Stomata
The photosynthesis equation
light energy + carbon dioxide + water --> glucose + oxygen
When can lactic acid fermentation occur?
Ms. Cobb's Discretion
ex: a very fast run
What do chromatids contain?
Identical DNA
T/F - Photosynthesis and respiration form a cycle that keeps the levels of water and carbon dioxide fairly constant in the atmosphere.
False; oxygen
