Plant Life Cycle Challenge!

Which of these is NOT a necessary condition for plant growth?

• Sunlight

• Water

• Air

• Plastic

Answer explanation

Plastic is not essential for plant growth. Plants require sunlight, water, and air to perform photosynthesis and respiration, while plastic does not contribute to these vital processes.

Pollination is the process where seeds are spread to new locations.

• True

• False

Answer explanation

Pollination is the transfer of pollen from male to female parts of flowers, enabling fertilization. It does not refer to the spreading of seeds, which occurs after fertilization. Therefore, the statement is false.

Which part of the plant is primarily responsible for photosynthesis?

• Roots

• Stem

• Leaves

• Flowers

Answer explanation

The leaves are primarily responsible for photosynthesis, as they contain chlorophyll, which captures sunlight and converts carbon dioxide and water into glucose and oxygen.

What is the main purpose of plant roots?

• To absorb water and nutrients

• To produce flowers

• To perform photosynthesis

• To attract pollinators

Answer explanation

The main purpose of plant roots is to absorb water and nutrients from the soil, which are essential for the plant's growth and survival. Other options like producing flowers and photosynthesis are functions of different plant parts.

Which method of seed dispersal is shown in this picture?

Answer explanation

The method of seed dispersal shown in the picture is likely wind dispersal, where seeds are carried away by the wind, allowing them to spread over a wide area. This is often seen with lightweight seeds or those with wings.
