| Question | Answer |
|---|---|
| What is diffusion? | The movement of material from high concentration to low concentration. |
| What is Osmosis? | The movement of liquid and material through a membrane. During osmosis, water moves from an area of more water, to an area of less water. |
| What is asexual cell reproduction? | A single cell producing an offspring exactly like the parent cell. |
| How is asexual cell reproduction used in single celled organisms? | It is used for reproduction. |
| How is asexual cell reproduction used in multicellular organisms? | It is used for growth, development and healing. |
| What is 2 advantages of asexual cell reproduction? | It's fast. It only requires one parent. |
| What is a disadvantage of asexual cell reproduction? | There is no diversity. |
| What are 3 kinds of asexual reproduction? | Fission, budding, and vegetative propagation. |
| What is fission? | A single cell splits into two. |
| What is the simplest form of reproduction? | Fission |
| What is an example of an organism that uses fission? | bacteria |
| What is budding? | A new organism grows from a parent and breaks off. Parent may form several buds, parent remains intact. |
| What is an example of an organism that uses budding? | Hydra |
| What is vegetative propagation? | Growing a new plant from a parent plant. Faster than growing from seeds. Identical plants can be grown with desirable characteristics |
| What are 2 examples of plant that use vegetative propagation? | Potatoes, spider plant |
| What is Sexual reproduction? | The making of a new cell from the joing of a male and female reproductive cell. The new cell has characteristics of both parent cells. |
| What are the advantages of Sexual reproduction? | It creates diversity because each new cell inherits different combinations of genes from the parents. |
| What are the 2 disadvantages of Sexual Reproduction? | Requires 2 cells to occur. Slower process than asexual reproduction. |
| What type of reproduction is mitosis? | asexual reproduction. |
| What is asexual reproduction? | One cell divides and forms 2 new identical cells |
| What is the dividing cell in Mitosis or asexual reproduction? | Parent cell |
| What are the new cells called in Mitosis or asexual reproduction? | daughter cells |
| What are chromosomes made of? | Genes |
| What do genes contain? | DNA |
| What does 10x mean? | a magnification of 10 times |
| What do microscopes do to objects? | Magnify |
| What shape is the field of vision in a microscope? | circle |
| What is the field of vision? | What is seen through a microscope |
| What happens as the magnification increases in a microscope? | the field of vision decreases |
| How do you determine the total magnification seen? | Multiply the magnification of the eyepiece by the magnification of the objective lens. |
| What is the function of the Lysosome? | small round structures that break down large food molecules |
| What is the function of the ribosomes? | Protein making sites |
| What is the function of the nucleolus? | where the ribosomes are produced |
| What is the nickname for the Nucleolus? | The little nucleus. |
| What is the function of the Nucleus? | the control center of the cell |
| What is the function of the endoplasmic reticulum? | transportation system of the cell |
| What is the endoplasmic reticulum made up of? | Tube-like passages |
| What is the function of thge chloroplast? | contain chlorophyll |
| What is chlorophyll necessary for? | photosynthesis |
| What is the function of the Nuclear membrane? | protects the nucleus and allows material to pass in and out. |
| What is a Prokaryote? | a cell with no nucleus. Genetic material is spread throughout the cell. |
| What is the function of Mitochondria? | Provides energy for the cell |
| What is the function of the cell wall | supports and protects the cell. Found only in plants |
| What is the function of the chromosome? | responsible for passing traits of a cell to a new cell |
| What is the function of the cell membrane? | Controls movement of liquid in and out of the cell |
| What is cytoplasm? | Clear, thick, jelly-like substance |
| What is the vacuole? | large, round, water-filled sacs in the cytoplasm |
| what is the function of Vacuole? | for storage |
| What is a Eukaryote? | cell with a nucleus |
| What are the 3 types of body systems? | Cirulatory, Skeletal, muscular |
| What is the function of the circulatory system? | to carry nutrients and oxygen to all the cells in the body |
| What are the main organs in the circulatory system? | Heart, veins, arteries |
| What are healthy practices for the circulatory system? | Healthy diet, exercise |
| What is the function of the skeletal system? | To provide support and protect organs. |
| What are the main organs of the skeletal system? | Skull, ribs, pelvis, femur |
| What are the diseases of the circulatory system? | High blood pressure, stroke, heart disease |
| What are the diseases of the skeletal system | Osteoporosis, scurvey |
| What are healthy practices for the skeletal system? | Healthy diet, exercise, wear helmet |
| What is the function of the muscular system? | To allow movement in the body |
| What are the main organs of the muscular system? | skeletal muscles-connect bones. smooth muscles-no control over these: stomach, intestines. Cardiac muscles: heart. |
| What are the diseases of the muscular system? | Multiple sclerosis, tetanus |
| What are healthy practices of the muscular system? | Exercise, healthy diet |
