Sample questions

1. Which part of a flower typically attracts pollinators with its bright colors and sweet scent?

   1. Sepal
   2. Petal
   3. Pistil
   4. Stamen
   Show answer

   Answer: B. Petal

   Petals are usually the most colorful and fragrant parts of a flower, designed to attract insects and other animals for pollination.

2. The process of a seed developing into a new plant is called:

   1. Pollination
   2. Fertilization
   3. Germination
   4. Dispersal
   Show answer

   Answer: C. Germination

   Germination is the process by which an organism grows from a seed or from a spore. For seeds, it is the process of the embryo emerging from the seed and beginning to grow.

3. Plants like dandelions use which agent for seed dispersal?

   1. Water
   2. Wind
   3. Animals
   4. Gravity
   Show answer

   Answer: B. Wind

   Dandelion seeds are attached to a fluffy parachute-like structure (pappus) that allows them to be carried long distances by the wind.

4. Which part of the flower is typically found at the tip of the pistil and is responsible for catching pollen?

   1. Ovary
   2. Style
   3. Stigma
   4. Anther
   Show answer

   Answer: C. Stigma

   The stigma is the uppermost part of the pistil, characterized by its sticky or feathery surface, designed to trap pollen grains during pollination.

5. The process of a plant producing offspring is called:

   1. Photosynthesis
   2. Respiration
   3. Reproduction
   4. Transpiration
   Show answer

   Answer: C. Reproduction

   Reproduction is the biological process by which new individual organisms – 'offspring' – are produced from their 'parents'. In plants, this can be sexual or asexual.
