Grew best of all three.
The plant likely died.
Grew poorly despite water.
The green pigment that captures sunlight — why most leaves are green.
The carbohydrate form in which plants store their food.
A leaf turns blue-black with iodine only where there's chlorophyll and sunlight.
A leaf part sealed away from carbon dioxide doesn't form starch — the exposed part does.
Tiny pores, usually on the leaf's underside, letting gases move in and out.
Xylem carries water upward; phloem carries food to the rest of the plant.
Germinating seeds turn lime water milky — proof they respire, without any light at all.
Green or not, every part of a plant releases energy for growth through respiration.
Uses carbon dioxide, water, and sunlight — makes food and releases oxygen.
Uses glucose and oxygen — releases carbon dioxide, water, and energy for growth.
The green pigment that captures sunlight.
The stored form of a plant's food.
Making food using sunlight, CO2, and water.
Tiny pores for gas exchange on a leaf.
Carries water and minerals upward.
Carries food to the rest of the plant.
Releasing energy from glucose using oxygen.
The simple sugar made by photosynthesis.
