Assessment: Multiple Choice Plant Parts Review Teacher Observation IV - 2 Background Information Roots and Stems and Leaves, Oh My! Plants have different parts just like we do. We have arms, legs, a heart and lungs to help us survive. Each of our body parts has a certain job to do. Plants have different parts, each with its own job to do. They must have roots, stems and leaves. Each part of the plant must do its job so the plant can stay healthy and grow. Roots A plant’s roots grow under the ground. The roots help hold the plant in the soil. They also take in water and nutrients which the plant turns into food. Plants have different kinds of root systems. Some plants have fibrous roots. Fibrous roots have many branches and spread out like the branches of a tree. Plants that have fibrous root systems include grasses, corn plants, wheat and many other crops that farmers grow. Other plants have a tap root. This is a single, main root that grows straight down. The tap root has smaller branches growing off of it. Examples of plants that have a tap root are carrots, radishes and turnips. Stems The stem grows upward from the roots. It holds the plant up and carries water from the roots to the other parts of the plant. Secondary stems, called petioles, grow from the main stem. These petioles have leaves growing on them. Sometimes we eat the stems of plants, like celery and asparagus. Leaves The leaves of a plant make the food the plant needs to survive. The water and nutrients that were taken in by the roots, move upward through the stem to the leaves. The leaves take sunlight and carbon dioxide from the air and convert the nutrients to plant food. This process is called photosynthesis. We eat the leaves of some plants such as lettuce and spinach. Flowers, Fruit and Seeds When a plant receives the proper amount of water, nutrients, air and sunlight it produces flowers. The flowers usually grow on the stems. When the flower dies and falls off it leaves behind a fruit. The fruit contains seeds. Fruits that we eat include apples, oranges, watermelons and tomatoes. Sometimes we let the seeds dry out and use them for food. Things like corn, peas and beans are examples of seeds that we eat. The seed is the part that grows a new plant. If we plant a bean seed we will get a plant just like the one that made the seed. omen e F292, 0 O29 BA Fre O2% BA 0,9 pA | O,e he a A plant has roots which keep it in the ground. The roots also take in water and minerals from the soil. Above the ground is the main stem. It holds up the plant and carries water throughout the plant. : Secondary stems , or petioles, grow from the main stem. These stems have the leaves. Green leaves make most of the plants food. The flowers of the plant produce fruit. Inside the fruit are the seeds. The seeds produce new plants. “ @%rnPnomonoFaMreOn® soporte md O19 pteoe, pA’ IV-5 wFr.e On, Fr. 0 92% ma. oO2% Bp» O,° pA @O,8 yA OVeomF,.e On.
