Lesson 3
| Term | Definition |
|---|---|
| Stomata | Is a small opening on the underside of a leaf through which oxygen ,water, and carbon dioxide can move [plural: Stomata]. |
| Transpiration | Is the process by which water is lost through a plant leaves. |
| Germination | Is the sprouting of the embryo out of a seed; occurs when the embryo resumes that growth following dormancy. |
| respiration | is the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen. |
| flower | the reproductive structure of an angiosperm. |
| Pollination | is the transfer of pollen from male reproductive structures to female reproductive structures in plants. |
| List the 3 functions of roots | Roots anchor a plant in the ground, absorb water, and minerals from the soil, and sometimes store food. |
| List the 2 functions of stems | the stems carries substances between the plant’s roots and leaves . The stem also provides support for the plant and holds up the leaves so they are exposed to the sun. |
| Describe the basic function of leaves. | Leaves capture the sun’s energy and carry out the food- making process of photosynthesis. |
| What is the difference between photosynthesis and cellular respiration? | Respiration releases energy by breaking down glucose and other food molecules in the presence of oxygen. Photosynthesis is the process by which plants and other autotrophs capture and use light energy to make food from carbon dioxide and water. |
| List the 3 ways a seed can be dispersed. | 1. animals eat food, the seeds pass through their jet digestive system and are deposited and new areas. 2. other seeds are enclosed in barb like structures that hook onto fur or clothing. 3. water also disperses seeds, into oceans and rivers. |
| Describe with each part of the flower does. | Pistol is found in the center part of the flower. The stamens are the male reproductive parts. Pedals are the most colorful part of the flower. Sepals protect the flower . Ovary protects the seed as they develop. |
| Label the basic parts of the flower (see diagram note sheet) | Stamen, pistol, pedal Sepal, stem, filament, stigma ,style, ovary. |
