Question 1 Photo

In which process do green plants produce their own food?

  • Photosynthesis
  • Diffusion
  • Respiration
  • Chlorophyll

Question 2 Photo

What is the equation for photosynthesis?

  • Glucose + Oxygen ---> Energy + Carbon Dioxide + Water
  • Carbon Dioxide + Water ---> Glucose + Oxygen
  • Glucose ---> Lactic Acid (+Energy)
  • Glucose ---> Ethanol + Carbon Dioxide (+Energy)

Question 3 Photo

The energy needed for photosynthesis is trapped for the plant by what?

  • Light
  • Glucose
  • Starch
  • Chlorophyll

Question 4 Photo

Most of the Carbon Dioxide that the plant uses during photosynthesis is absorbed from the air, what other source of Carbon Dioxide is there?

  • Respiration in the plant
  • Water
  • Osmosis in the plant
  • From the soil

Question 5 Photo

The diagram shows some plants in a greenhouse, what factor may limit the rate of photosynthesis?

  • Light intensity
  • Temperature
  • Carbon Dioxide concentration
  • Amount of soil for the plants

Question 6 Photo

Through which part do mineral salts get into the plant?

  • Root Hair Cells
  • Epidermal Cells
  • Bundle Sheath Cells
  • Mesophyll Cells

Question 7 Photo

Why is water important in the process of the plant getting mineral salts through the Root Hair Cells?

  • The minerals have a ''Key and Lock'' system with the Root Hair Cells.
  • The minerals are dissolved in the water, which transports salts throughout the plant.
  • The minerals need to be dispersed.
  • The minerals need to mix with the water, allowing the plant to digest them.

Question 8 Photo

In the plant, what are Nitrates used for in the seedling?

  • To produce proteins and amino acids.
  • To help the plants grow.
  • To strengthen the cell's stem.
  • To increase the grow the the plant.

Question 9 Photo

If growers are planning to produce the most profit possible from growing lettuce, what do they need to consider before choosing the growing conditions?

  • Cost of providing the conditions.
  • The amount of lettuce growing companies.
  • The temperature outside the greenhouse.
  • The amount of people who eat the lettuce.

Question 10 Photo

What environmental factor, other than the light intensity and Carbon Dioxide concentration, can limit the rate of photosynthesis?

  • Temperature
  • Ions
  • Nitrates
  • Density of planting
