When grass is cut with a lawn mower, it gives off a distinct aroma
When grass is cut with a lawn mower, it gives off a distinct aroma. Why does newly-mowed grass smell a little bit sweet? Sugars are produced when the cut leaves of grass begin to decay in sunlight. Sugars stored in the roots are sent to repair the damage to the grass leaves. When the grass leaves are damaged, some of the sugar produced in the leaves escapes. When grass leaves are cut, a small amount of sugar is produced at the site of injury to plug the phloem. C

Identifying food lab Oregano – spice from leaves White rice- seeds
Red potatoes-modified plant structures that are enlarged to store nutrients- part of the stem Peanuts- legume or bean- that contains seeds Pineapple stem- part of the fruit that produces flowers Onion- veggie- modified stem for storage Beans- enlarged plant seeds Tomatoes- fruit Carrot- root veggie Oatmeal- part of seeds of oat plants

Flower Questions Why colorful petals?
Why are sepals and petals called accessory parts? Why is it important to elevate the anthers? Two ways pollen can get to stigma… Why more stamen than pistils? Why elevate the stigma? How does the structure of the stigma aid in pollination? Which part of flower develops into seeds? When fertilized what will ovary grow into?

ATP/Photosynthesis/Cellular Resp.
What the heck is that?

root hairs, xylem, stomata phloem, root hairs, xylem
In plants, water can escape through the leaves by the process of transpiration. Which of the following structures are involved in transpiration? xylem, phloem, stomata root hairs, xylem, stomata phloem, root hairs, xylem stomata, phloem, root hairs FUN FACT: Only 1% of the suns energy is absorbed by plants, the rest is reflected back to space or transformed into heat in the atmosphere B

Ted-ED Video: Photosynthesis and Cellular Respiration
On average, what percentage of the food we eat on a daily basis comes from carbohydrates? What are the pores in a plant's skin called? The sun helps plants transform carbon dioxide into a simple carbohydrate called: What's another name for cellulose? Which organelle is ultimately responsible for breaking down carbohydrates into usable energy at the molecular level? In five sentences or less, list the major steps involved in photosynthesis.

Get out a piece of paper- Title it Plant Quiz
3 short answer, 4 multiple choice 1) Describe the difference between xylem and phloem. 2) Describe the process of transpiration. 3) Explain the purpose and function of flowers for a plant. Would the plant survive without petals? Explain.
13
Multiple choice 4)What is the main function of leaves?
A. Leaves provide support for growth and a place to store food. B. Leaves provide a place for photosynthesis to occur. C. Leaves absorb water and minerals and transport nutrients to the stem. D. Leaves create a barrier that prevents water in the plant's tissues from evaporating. B
14
5) Terrestrial plants have stomata on the surface of their leaves
5) Terrestrial plants have stomata on the surface of their leaves. A single stomata is surrounded by two guard cells that change shape in response to environmental factors and open or close the stoma. Which of the following best explains how the structure of the leaf is used in processes that occur in plants? A. Water enters the plant through the surface of the leaf for transpiration B. Gases for photosynthesis are exchanged through the surface of the leaf. C. Energy for cellular reproduction is absorbed through the surface of the leaf. D. Carbon dioxide enters the plant through the surface of the leaf for cellular reproduction. B
15
Which structure is represented by the letter A in the diagram above?
6) The diagram below represents a flower, the reproductive structure of some plants. Most flowers have both male and female structures for fertilization and reproduction B Which structure is represented by the letter A in the diagram above? A. the stamen, a male structure which produces pollen B. the pistol, a female structure which collects pollen and passes it to the ovary C. the sepal, a modified leaf used for protection of the flower D. the petals, decorative structures which attract pollinators

7) A unique characteristic of the banyan tree is that roots grow down from its branches into the ground. The tree can appear to have several trunks. What advantage does this root characteristics give the banyan tree over other trees? The roots provide shelter for ground dwelling animals, which carry nutrients to the tree It can grow near the equator, because aboveground roots are more protected from the sun It can only grow in humid climates because aboveground roots are more likely to dry out and die during droughts It can grow in areas prone to hurricanes and typhoons, because the roots make the tree more stable in high winds D
17
Quiz Answers 1) Xylem- Vascular plant tissue that carries water. Phloem- Vascular plant tissue that carries sugars. 2) Transpiration is the process of water movement through a plant and its evaporation from leaves. 3) The purpose of the flower is for plant reproduction. The plant can survive without petals on the flower because it is not directly involved in the reproduction of the plant. 4) B 5) B 6) B 7) D
