chapter 1 test science
| Question | Answer |
|---|---|
| Cell | is the smallest unit of a living thing that can carry out the basic processes of life |
| Organelle | are structures that work that work together to help perform |
| Cell membrane | is a layer around the outside if the the cell |
| Cytoplasm | is a gel-like substance that supports all of the organelles that carry out the different jobs |
| Nucleus | is a large spherical structure found in the center of the cell |
| Mitochondria | cells have many oval cacs called this |
| Vacuoles | organelles that store water, food, and wastes |
| Cell wall | is an additional layer around the outside of the cell made from a hard specialized sugar called Glucose |
| Chloroplasts | it is green because of the chemical chlorophyll which turn energy from sunlight into food |
| Microscope | an instrument that magnifies objects |
| Unicellular | is a one-celled organism |
| Organism | is an individual living thing |
| Multi-cellular | is an organism made up of many different kinds of cells |
| Tissue | is a group of similar cells that do the same job in an organism |
| Organ | in plants and animals, tissues of different kinds come together to make this |
| Kingdom | is the broadest group into organisms are classified |
| Invertebrates | are animals without a backbone |
| Vascular | means composed or containing vessals |
| Nonvascular | means they do not contain vessal |
| Fungus | is a unicellular or multi-cellular organisms that feed off decaying or dead organisms |
| Bacteria | are tiny unicellular organisms with a cell membrane and cytoplasm |
| Protists | are unicellular or multi-cellular organisms that either make their own food or other living things |
| Animals can be invertebrates | True |
| Plants can be vascular and nonvascular | True |
| Fungi absorb food from decaying organisms | True |
| Bacteria are unicellular organisms | True |
| Organ systems make up the organisms | True |
| Plants and animals have many different organ systems to carry out life processes | True |
| All living things are made of cells, which are the smallest unit of a living thing that can carry out the basic processes of life | True |
| How do plants and animals obtain energy differently? | Plants get energy from the sunlight; animals get energy from eating plants or other animals that eat plants. |
| Explain how the parts of an organism are organized from most simple to most complex? | Organisms can be unicellular or multi-cellular. Simple cells make up tissues, which make up organs, which work together to do certain jobs as organ systems. |
