Arya wanted to check the effect of a new fertilizer on different flowering plants. She took 12 pots and put soil mixed with fertilizer in 6 of them and put plain soil in the other 6 pots. She then took seeds of 6 different plants and planted the seeds of each plant in a pot with fertilizer as well as in a pot without fertilizer. She then provided equal amounts of water to all the pots and checked the number of flowers each plant produced for a week. Study the graph given below and answer the following question: For which plant did the fertilizer have no effect on the number of flowers?

Explanation:
Many things in nature help to regulate plant growth: sunlight, proper temperature, moisture, air, and
nutrients. These are referred to as environmental factors. Each part of a natural or artificial environment
affects the survival and quality of a plants life. Knowing the basic facts about the way in which plants live
and grow will help you understand plants.
Light: All living things, except for a few groups of bacteria, depend on photosynthesis for their
existence. Photosynthesis is the process by which green plants make their own food. In the presence of
light energy, plants manufacture food (mainly sugars), by combining carbon dioxide and water in the
presence of chlorophyll to release oxygen and water.
Proper Temperature: Temperature is the most important environmental factor affecting plant growth.
Plants vary in their temperature needs. The ability of a plant to withstand cold temperatures is known as
hardiness. Plants that cannot tolerate cold weather are known as tender plants.
Water: Water is essential for life. It is one of the most important requirements for plant growth. Water
is the main component of plant cells, it keeps the plant turgid (stiff), it's used in photosynthesis, and it
transports nutrients throughout the plant.
Air: The manufacture of carbohydrates and proteins which a plant needs to live and grow requires raw
materials. These materials are either found naturally in the environment or supplied by the grower.
Plants absorb the raw material carbon dioxide from
