Plants for food quiz

15 Questions

Quiz Description

We will be looking at Food as one of the most important things to living things in this quiz, especially animals. We eat food every day and if we were to be asked why most people will say we eat to live. This is very true, Feeding or as we call it nutrition is the process of acquiring food, one of such food, is/plant. Herbivores and Omnivores feed on plants for food. 

Plants provide the body with the necessary nutrients required for the proper functioning of the body and studying these plants as food is important for this, and also, not all plants are food, so this topic teaches you about edible plants and non-edible plants too.

Now, what is a plant?

A plant is any living thing that grows out of the earth(soil) and has a stem, leaves, and roots. Some are edible, while others are not. For Example, Oleander. It is not only non-edible, but it is poisonous, so it cannot be taken in for food by man. While the potato plant is a very nutritious and edible plant for its roots.

You will find a set of 15 MCQ questions, each having 4 options giving you a chance of  ¼  for a pass. Take the quiz and prove how well you are familiar with plants for food. This website offers you free educational and interesting quizzes, you will find more

1:

Which statement is NOT true about plant growth?


Correct
  • 1:
      It is more difficult for roots to absorb water if the soil is hard and compacted.
  • 2:
     Plants only need water for photosynthesis to make food.
  • 3:
      Bacteria in soil need oxygen for respiration forming carbon dioxide that plant's can use.
  • 4:
     In a poorly lit room a plant stem will bend towards a window to increase the rate of photosynthesis.
2:

The use of pesticides like DDT to protect crops (grain, fruit etc.) from insect damage is strictly controlled. Chemicals like DDT tend to be insoluble in water but soluble in fatty or oily materials. Some countries have banned their use because of harmful effects on the environment as the pesticides become part of food chains. In the food chain illustrated, the use of 'DDT like insecticides' led to a decline in birds of prey like the kestrel (often due to poor quality egg shells or or organ poisoning effects).  Which of the following is most likely NOT to be true?


Correct
  • 1:
    The DDT concentration in the organism increases up the food chain (=>).
  • 2:
     The insects absorb the DDT from the air around the plants or insects.
  • 3:
     The insects ingest the DDT if they eat any part of the plants or even absorb it by contact.
  • 4:
     The DDT molecules are chemically very stable.
3:

  • 1:
    photosynthesis
  • 2:
    energy
  • 3:
    producer
  • 4:
    chain
4:

  • 3:
    chain
  • 4:

5:

A series of experiments was done to see the effects of various minerals on the quality of plant growth. More importantly, these experiments can show the effects of a soil that is lacking (deficient) in any essential mineral. From the experiment data, which mineral deficiency causes poor quality flower blooms?

A gardener noticed that the quality of a vegetable crop depended on the number of tall fast growing weeds near the vegetable plants. Which of the following would you NOT expect about the quality of the vegetables in amongst many weeds, compared to those growing free of weeds?
