Flashcards in Photosynthesis and respiration Deck (14):

When and where does photosynthesis occur?

Photosynthesis takes place inside plant cells in small things called chloroplasts. Chloroplasts contain a green substance called chlorophyll. This absorbs the light energy needed to make photosynthesis happen. Plants can only photosynthesise in the light.


Reactants of photosynthesis

Carbon dioxide and water and sunlight


Products of photosynthesis

Glucose and oxygen


Word equation for photosynthesis

Carbon dioxide + water ---sunlight and chlorophyll--- glucose + oxygen


Chemical equation for photosynthesis

6CO,2 + 6H,2O ---- C,6H,12O,6 + 6O,2


5 Difference between respiration and photosynthesis

Photosynthesis produces sugar and respiration burns it for energy
Photosynthesis stores energy respiration releases energy
Photosynthesis releases oxygen respiration use it
Uses carbon dioxide, produces carbon dioxide
Requires light to work, occurs in dark and light


Define photosynthesis

The process which some green plants use carbon dioxide as energy to produce oxygen.


Define aerobic respiration

A type of respiration in which oxygen is taken in and carbon dioxide and water are produced.


Define anaerobic respiration

The type of respiration that does not use oxygen. It happens when there is no oxygen or it is scarce


Equation for aerobic respiration

Glucose + oxygen ---- carbon dioxide + water + energy


Equation for anaerobic respiration

Glucose -- lactic acid + energy


Which part of a cell does respiration take place

In the mitochondria. It is the power house for the cell as it is the site for cellular respiration


What are stomata and how are they involved in photosynthesis

They make food from carbon dioxide and water in the process of photosynthesis. Carbon dioxide is taken from the air using stomata and oxygen is released as a waste.


What is the role of palisade

Absorb light used by the leaf
