| Question | Answer |
|---|---|
| What is a cell | The smallest unit that can proform all life processes ; cells are covered by a menbrane and have DNA and cytoplasm |
| What is stimulus | anything that causes a reaction or change in an organism |
| What is homeostasis | the maintenance of a constant internal state in a cnanging enviroment |
| Why is osmosis important to cels | Cells contain fluids that are mostly water |
| Sexual Reproduction is | when two sex cells from parents unite to make offspring that has traits from both parents |
| Protein | a molecule made of amino acids and is needed to repair body structure and to regulate processes in the body |
| What molecules form much of the cell membrane | Phospholipids |
| Why couldn't the air be just oxygen | Plants need carbon dioxd t omake food and other organisms use plants as food |
| Fermentation causes | lactic acid |
| Water diffuses into of out of a cell it is called | Osmosis |
| Most complex organisms obtain energy through | Cellular respiration |
| Which kind of cells contains mor DNA | Eukaryotic cells |
| Mitosis | the process of chromosome seperaation |
| Movement of substance without the use of energy | Passive transport |
| Examples of active transport are | Endocytosis and exocytosis |
| Complex carbohydrate manufactured by plants | Starch |
| What do most metabolism chemical reactions require | Water |
| Which is not a charastic that all organisms share | Ability to tast and smell |
| Gravity sounds and light are all | Stumili |
| A group of organs that have the same funcion make up | Organ systems |
| a group of similar cells that proform a common function | Tissues |
| Tissues working together form | Organs |
| asexual reproduction | reproduction that does not invlv the union of sex cells |
| Producers | an orgaicm tha can make its own food |
| Consumer | organism that eat other organisms |
| Decomposer | and organism that gets energy by breaking down dead organisms |
| Nucleic acid | a molecule made up of subunits called nucleotids |
| Cell Membrane | a phospholipid layer that covers a cells surface; acts as a barrier between the inside of a cell and the environment |
| Organelle | one of the smallest bodies in a cells cytoplasm that are specialized to proform a specific function |
| Nucleus | ina a eukaryotic cell, a menbrane bound organelle that contains the cell's DNA and that has a role in processes such as growth, metabolism, and reproduction |
| Prokaryote | an organism that consists of a single cell that does not have a nucleus |
| Eykaryote | and organism made up of cells that have a nucleus enclosed by a membrane, they inclide animals, plant, and fungi |
| What are 3 advantages of being multicellular | Larger size, longer life and specialization of cells |
| Cell wall | rigid structure that surrounds the cell membrane and provides support to plant cells |
