Question 1) The part of the plant that takes in water and minerals from the soil are called ______?

  • Roots are the part of the plants we usually can’t see, because they are under the soil. They go there to grab nutrients and water, as well as to anchor the plants!1

Question 2) Plant food production is referred to as __________?

  • Plants transform carbon dioxide (CO2), water (H2O), and sunlight into food. This transformation process is called photosynthesis.2

Question 3) What is the initial stage of plant development?

  • Seeds have packed inside everything a new plant needs! When the conditions are good, the seeds start to germinate and slowly become grown plants.3

Question 4) What is the process in which pollen is transferred by insects to other flowers?

  • When insects carry pollen to other flowers – the process we call pollination –  they are helping plants that have seeds to reproduce. If it weren’t for this process, plants could not give us fruits.4

Question 6) Which of these plants has the ability to spread its seeds into the water?

  • Water lilies live in water and their seeds float away.6

Question 7) How does the plant get water from the soil?

  • The soil stores a lot of water and long roots grab this precious resource by going deep under the ground.7

Question 8) What is the name of the sweet liquid that insects consume when they feed on flowers?An orange flower close up in Sequoia National Park, with an 8 Billion Trees watermark.

  • As far as we know, flowers do not produce milk nor tea. However, they have glands – called nectaries – that produce this sweet liquid (nectar) insects love!8

Question 9) What animals are responsible for pollinating plants and flowers?

  • Although bees are the most famous pollinators, many other insects – and even other animals – pollinate flowers and plants.9

Question 10) Seeds develop in which section of a flower?

  • Animals carry pollen from the male part of a flower to the female part of another flower – where the ovary is. When pollen grains arrive in the female parts of flowers, they create tubes that go down to the ovaries and fertilize ovules. Seeds start to develop when this fertilization process happens!10
