photosynthesis

• what is the word equation for photosynthesis?

  carbon dioxide + water -> glucose + oxygen
• whats the equation for photosynthesis?

  6CO2 + 6H2O + light energy -> C6H12O6 + 6O2
• what is starch made out of?

  glucose molecules in a chain
• what is the function of chloroplast?

  the site of Photosynthesis
• what is the green substance in chloroplast called?

  Chlorophyll
• what minerals are important for plant growth?

  Nitrate, phosphorus, potassium and magnesium
• what do minerals salts do?


  help plants grow
• what is nitrate needed for?

  help in making protein like new cells, DNA and chlorophyll
• What is Magnesium needed for?


  Chlorophyll
• what is phosphorus needed for?

  development of roots, flowers, seeds and fruits
• what is potassium needed for?

  promotes roots, flowers and fruit development and helps in resisting diseases
• how does the water change during photosynthesis?

  Chlorophyll absorbs light energy and that energy is used to split hydrogen and oxygen. Hydrogen and carbon dioxide work together to make Glucose.
• how does water keep a plant from wilting?

  the water enters the vacuole of the cell and presses against the the cell wall which makes the cell turgid
• what is it called when water pushes against the cell wall?

  turgor pressure
• what are the two main vascular tissues in a plant.

  xylem and phloem
• what happens when a plant doesnt get enough water

  the plant wilts and the cells will lose its shape and become flaccid.
• what is the function of the xylem?

  to transport water to the different parts of the plant
• what is the process of water entering the vacuole and making the cells turgid?

  osmosis
