Question

ASAP please write a hypothesis about which seedlings "light" or "no light" will grow taller one week after germination.

and please draw the graph

details needed thank you

ntroduction: Photosynthetic plants require light to make sugars in order to produce the energy to grow. Yet, when we think about plants needing light to grow, we do not intuitively understand how light affects the rate at which plants grow taller. Plants do exhibit positive phototropism, which means they grow towards light. However, more light does not mean a taller plant. Instead, when there is a young, recently sprouted tree in the forest growing under trees, it will grow taller in the same period of time as the same tree growing in full sun. "What?" you may ask. Well, the plant in the spot with less sun is "reaching up" to try to get to the light; the plant in full sun doesn't have to do any "reaching". Given this introduction, write a hypothesis about which seedlings,"light" or "no light" will grow taller one week after germination. Then go look up "etiolation" in a dictionary. You don't have to do the experiment below since data are provided to you already, but you may find it very interesting and beneficial to do the hands-on activity. Materials: 1.) One package of viable and fast germinating seeds 2.) A couple cups of potting soil 3.) Two containers to plant the seeds 4.) A spray bottle to watch the seeds S.) A tray to put the pots on to catch the water that comes out the bottoms 6.) A warm indoor space to put containers. 7.) A metric ruler

Answer 1

Hypothesis - a plant with no light grows taller and faster as it has water to grow. these plant searching for light because of positive phototropism. and plant with the light already getting light so it doesn't grow taller as no light plant as it has sufficient light.

This is readings with an average of two plants with light and no light.

no of plan no light light 1 3.333 3.333 2 26 23.66 3 61.6 57 4 82.6 70.66 5 89 74 6 92 76.33 7 95 78

This is graph showing the difference in growth in two plants.
