Cells
6th Grade - Cells (theory, processes, structure and function)
Key Term/Idea | Explanation/Definition |
---|---|
golgi apparatus | processing and packaging proteins that have exited the rough endoplasmic reticulum to be further transported inside and/or outside the cell. |
chloroplast | structure only in the plant cell that allows the plant to make its own food for energy |
chlorophyll | uses energy from the sun to produce a sugar called glucose that the plant uses for food. |
cell theory | 1- cells come from other existing cells. 2- cells are the basic unit of life 3- All organisms are composed of one or more cells. |
cell homeostasis | processes that include: obtaining energy, waste removal & reproducing |
role of microscopes | over time, the technology of this tool has evolved so scientists are able to learn and observe so much more about life. |
cell wall | this organelle provides shape, support, and protection to the cell and its organelles in plants |
cytoplasm | this organelle holds the components of the cell and protects them from damage. It also stores the molecules required for cellular processes. |
mitochondria | this organelle produces energy, regulates metabolism and promotes cell growth. |
cell membrane | also called the plasma membrane, this organelle regulates the transport of materials entering and exiting the cell. Allows for mobility in animals. |
vacuoles | membrane-bound sacs within the cytoplasm of a cell that store materials and transport waste. Plant cells have one large vacuole that stores water for photosynthesis, animal cells have multiple smaller vacuoles. |
nucleus | not only the cells control center this organelle also houses the cell's DNA thats used for transcription and replication. |
smooth endoplasmic reticulum | produces cellular products like hormones and lipids and distributes those products throughout the cell and to places in the organism. |
astrology | the study of the supposed influences of the stars on human affairs by their positions in relation to each other |
lysosome | this organelle breaks down fats and sends |
centriole | aids in reproduction in the animal cell |
astronomy | the study of everything in the universe beyond Earth's atmosphere. |
biology | the study of life |
chemistry | the study of properties, composition, and structure of elements and compounds, how they can change |
scientific law | a rule that describes a pattern in the natural world. Example: the harder the ball is hit, the faster it will travel. |
succrose | a disaccharide composed of glucose and fructose and is produces naturally in plants. |
glucose | a monosaccharide or simple sugar, making it the simplest type of carbohydrate. |
fructose | a monosaccharide that is a naturally occurring sugar found primarily in fruits |
