See the following text/image to answer questions 1 through 5

Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into sugar and oxygen. Photosynthesis is used by plants and some protists, bacteria, and blue-green algae.

The process of photosynthesis takes place in the cells in the plant's leaves, called chloroplasts. It is those chloroplasts that capture the sun's energy with a green pigment called chlorophyll. Chlorophyll then uses that energy to combine Carbon dioxide and Water to create Sugar and Oxygen . Plants and animals then use the sugar for food and energy. Animals use the oxygen to breathe.

See the following text/image to answer questions 6 through 10

Pollination is a very important process for the survival of our planet. It leads to the creation of fruits that we consume and new seeds that grow into new plants. Pollination occurs when pollens are moved from the anther of one flower to the stigma of another flower. An anther is the male part of a flower that grows pollen grains. A stigma is the female part of a flower that receives the pollen. Most plants are pollinated by insects, birds, bats, and other organisms. Bees are the primary pollinator on the earth. Some plants are self-pollinated. They have anther and stigma, both on their flower.

Plants that are pollinated by animals often are brightly colored and have a strong smell to attract the animal pollinators. Another way plants are pollinated is by the wind. The wind picks up pollen from one plant and blows it onto another. Plants that are pollinated by wind often have long stamens and pistils.
