Does Purple Basil Grow Better in Dark
or Light Conditions?
• In this presentation we will discuss Purple
Basil and how it survives. We will also discuss
the growth of Purple Basil in light and dark
conditions.
Labeled Parts
• Purple Basil’s scientific name is Ocimum
basilicum L. Purpureum.

Purple Basil
• Purple Basil’s organic compounds is probably
used for insecticide
• The organic compound helps the plant survive
by keeping away bugs
• Purple Basil is used in cooking
• Italians put Basil in their hair to symbolize
love.
Background Info
What effects Purple Basil’s growth
Soil
Amount of water
Amount of sunlight
Photosynthesis
• Photosynthesis- when plants use the energy from sunlight,
Co2, and H2O to create sugar.
• chemical reaction- turning sunlight, Carbon Dioxide, and
Water to create Sugar and Oxygen.
• The Chloroplast is the organelle that conducts Photosynthesis
• Xylem moves Water, Oxygen, and other nutrients from the
roots to the leaves. Once the nutrients reach the leaves,
Photosynthesis can now happen.
Procedures
• We first labeled our cup with group name
and class.
• We first placed the cotton at the bottom of
the cup followed by soil and 3 seeds.
We continued to water the plant and make
observations.

Other Observations
• The plant grew toward the light. This process is known as
positive phototropism. The roots grew into the soil in a
process called positive geotropism. We observed that the dark
plant grew faster than the light plant but then it died after the
plant could not make enough sugar for photosynthesis.
• phototropism
Summary
• The results that we found out were the dark plant died. The
light plant stayed alive. Since the dark died and the light
stayed alive, our hypothesis supported the data. Our
hypothesis was wrong because the dark plant was taller than
the light until it died. The questions we had were, would the
plant die if we added hand sanitizer to it? And, If we took the
dead plant and put it in the sunlight, could we save it?
