Name: Date of Test: Plant Test Review Key Directions: Define the following terms listed below. Use a separate sheet of paper if you can’t fit them in the space provided. Take this home and study. Geotropism-­ gravity causing a response in plant growth Hydrotropism-­ the way a plant bends or grows in response to water Phototropism-­the way a plant bends or grows in response to light Photosynthesis-­ the process in which plants produce glucose and oxygen using carbon dioxide, light energy, and water. Chloroplast-­ the organelle that contains the chlorophyll that trap the sunlight needed for photosynthesis Chlorophyll-­ the green pigment in plant cells that traps the sunlight needed for photosynthesis Stimulus-­ any factor in the environment that causes a response Response-­ reaction to a stimulus Transpiration-­plants losing liquid through their leaves, stem, flowers, or roots Respiration-­ taking in and releasing gases Botanist-­ a scientist that studies plants What is the function of each plant part? Stem-­moves water and nutrients to parts of the plant and supports the plant Roots-­ brings up water and nutrients to the plant from the soil and keeps the plant in place Leaves-­ where photosynthesis takes place and food is made Flower-­ reproductive part of the plant that contains pollen What are the five characteristics of living things? 1. reproduce 2. grow & die 3. react to surroundings 4. need energy, nutrients, air, and water 5. made up of cells Plants give off the gas Oxygen and we breathe it in. We breathe out the gas Carbon Dioxide and plants take it in. If a potted plant is knocked over on its side and is left there for weeks, what will happen to the roots? They will begin to move and point down because of gravity. What is used during photosynthesis? Sunlight, water, carbon dioxide What is created during photosynthesis? Glucose and oxygen As much as 90 percent of the oxygen in our atmosphere is the result of photosynthesis . Photosynthesis is the process in which plants use energy from light to produce food or glucose . Plant cells have cell walls and chloroplast while animal cells do not. List the steps of photosynthesis labeled here: 1. Oxygen is produced 2.Carbon Dioxide is taken in by the plant. 3. The Sun’s energy is absorbed. 4. The roots take in water. 5. Glucose is formed in the leaves. 3 1 2 5. What is formed here in the leaves? 4
