| Term | Definition |
|---|---|
| aerobic cellular respiration | a process by which organisms convert glucose into usable energy |
| guard cell | a specialized plant cell that controls the opening and closing of the stomata and, as a result, regulates transpiration |
| organ | a structural unit made up of tissues |
| organ system | a group of organs that works together for one purpose |
| phloem | tissue within vascular plants that transport food and nutrients made in the leaves to other parts of the plant |
| photosynthesis | the process by which organisms that have chloroplasts use light energy, carbon dioxide, and water to make glucose |
| stoma | openings on the surface of leaves that allow gas exchange |
| tissue | material composed of similar cells that work together for a purpose |
| transpiration | the process by which water flows through plants, entering the roots and exiting the stomata |
| vascular system | a network of tubes that carry sugars and water to all parts of a plant |
| Xylem | a tissue made of long connected cells that transports water from the roots to all cells in the plant |
| atom | smallest particle of an element |
| molecule | a group of atoms bonded together |
| eukaryote | a cell that contains a nucleus and membrane bound organelles |
| prokaryote | a cell that lacks a nucleus and membrane bound organelles |
| organism | a living thing |
| chloroplast | an organelle found in plant and algae cell where photosynthesis occurs |
| evidence | collected body of data from observations and investigations |
| autotroph | an organism that produces its own food |
| heterotroph | an organism that consumes food |
| adaptation | any structure or behavior of an organism that allows it to survive in its environment |
| egg | female sex cell |
| sperm | male sex cell |
| germination | the growth and development of the seed into a new plant |
| pollination | the transfer of pollen from the anther to the stigma of a plant allowing fertilization of an egg |
| salinity | the amount of salt in a substance |
| salt tolerant | a characteristic of some plants that allows them to germinate and grow in salty environments |
| seed | a young plant in a dormant state |
| sexual reproduction | the creation of offspring when the genetic material from 2 parents is combined |
| cotyledon | the nutrients inside a seed that a plant uses during germination |
| anther | the top of the stamen where pollen is produced |
| stamen | the male part of the flower |
| pistil | the female part of the flower |
| petal | modified leaves that are often brightly colored |
| sepal | a type of leaf that protects the flower when it is in bud form |
