 * What are the jobs of the roots? **
 * //To absorb or take in water and minerals from the ground //
 * //To hold the plant in place. //
 * //To store food for the plant. //

**FLOWERS**

1.) What is an Angiosperm? What advantages does it have over other plants?
Answer: An Angiosperm is a flowering plant. Angiosperms attract insects who help pollinate and spread the seeds whereas other plants have to rely on the wind. [|Biology 4 Kids]

**2.) What are two functions that a petal on a flower serve?** Answer: Two functions that a petal of a flower serve are protecting the inside of the plant and attracting insects to the plant. [|Easy Science Fun]

**3.) What are the four main parts within an Angiosperm and what do they do?** Answer: The four main parts of an Angiosperm are Sepals, Petals, Stamens, and Carpels. The Sepal protects the flower as it grows, the petal attracts insects to the flower, the Stamen is responsible for making pollen, and the Carpel holds the Ovary, the Stigma, and the Style which all play roles in the fertilization process.

**STEMS**

** 1.) What is the name of the tubes in the stem that take the water and minerals up into the plant and the name of the tubes that carry the food back down the stem? **
 Answer: The tubes in the stem that take the water and minerals up into the plant are the xylem and the tubes that carry the food back down are called the phloem. **2.) What are the five main functions of the plant stem?** Answer: The five main functions of the plant stem are: 1. It supports the leaves, flowers and fruits and connects them with the roots. In trees and shrubs, the main stem or trunk provides a strong columnar structure from which branches are attached, raising the leaves upward to be exposed more fully to the sun. 2. It conducts water, nutrients and the products of photosynthesis to and from roots and leaves. It accommodates the transport system which is necessary for the vertical and lateral movement of water and sap within the plant body. 3. It helps store water, as in cacti, and the products of photosynthesis, as in the trunk of sago palm (Metroxylon sagu) and sweet palm (Arenga pinnata) which store large stock of starch; 4. Young green stem also performs a minor role in the production of food through the process of photosynthesis, but in some species (e.g. cactus) the stem is the chief photosynthesizing organ. 5. The plant stem serves as a means of asexual reproduction in many plant species.

**3.) What are three examples of food storing stems?** Answer: Examples of food-storing stems include such specialized forms as tubers, rhizomes, and corms.

Answer: Chlorophyll is a pigment found in the cells of leaves which is formed only in the presence of light and is the substance that colors plants green. Chorophyll is contained in chloroplasts and has the property of capturing light energy.
 * LEAVES **
 * 1.) What is Chlorophyll?**

**2.) Leaves are the site of what food making process?** Answer: Leaves are the site of a food making process called photosynthesis. In this process, carbon dioxide and water in the presence of chlorophyll (the green pigment) and light energy are changed into glucose (a sugar). This energy rich sugar is the source of food used by most plants.

Answer: Leaves are the major site of food production for the plant. Structures within a leaf convert the energy in sunlight into chemical energy that the plant can use as food. =Plants Provide Food= 1.) What do people and animals need to survive? Answer: People and animals need food and water to survive.
 * 3.) In most plants, leaves are the major site of what?**

2.) All food comes directly and indirectly from what source? Answer: All food comes directly and indirectly from plants.

[]

3.) What do plants need to make food? Answer: Plants need chlorophyll, light, carbon dioxide, nutrients and minerals to make food.

= Plants Provide Oxygen = 1.)What is [|photosynthesis]? Answer: Photosynthesis is the process that allows plants to take energy from the Sun and create sugars.

2.)Why is photosynthesis important for [|humans] ? Answer:Plants produce oxygen during photosynthesis. Humans need oxygen in order to survive. []
