phototropism
hydrotropism
Photosynthesis occurs during the ____________ and respiration occurs during the __________.
day; night
To do respiration, plants need--
sugar and oxygen
Respiration creates three things--
energy, carbon dioxide, water
being asleep or inactive
dormant/dormancy
Why don't baby leaf buds open until spring/summer?
conditions are favorable and good in the spring/summer

energy
What happens if you plant a seed upside down?
roots grow down in dirt; stem grows up towards the light
Why do plants grow towards the light?
they need light to make food/do photosynthesis
