Practice for a science test on cells
| Question | Answer |
|---|---|
| What is a theory? | accepted belief based on data collected, but can not be proven |
| Theories are based on what three things? | many expiriments and observations,original results observed by other people,must stand up to new research and observations |
| Who was the first person to describe cells? | Robert Hooke (1665) |
| What is the definition for Biology? | The study of living things (humans and animals) |
| What is the definition for botany? | the study of plants |
| Which type of cell has chloraplasts? | Plant cells |
| What does plants do during celluar resperation? | Plants store energy |
| scientific theory explains what? | It explains patterns in nature |
| What is the cell theory | *All living things are made of cells *cells give living things structure *cells do jobs to keep the living thing alive and healthy *all new cells come from other cells |
| What are the 4 basic parts of an animal cell and plant cell? | cell membrane, nucleus, cytoplasm,mitochondrion |
| what is cytoplasm? | *gell like substance *stores wastes *allows stuff to move along over in the cell |
| what is a cell membrane? | *surrounds the cell *controlls what moves in the cell *controlls what moves out |
| What are organelles? | other tiny structures found in the cell with their own job |
| What cell wall's job? | (being a doctor,JK) it supports and protects a cell wall |
| What are chloroplasts? | help's cells to make food using sun's energy |
| Where is chlorophyll found? | inside a chloraplast |
| what is chlorophyll? | a chemical that gives plant its green color |
| What does photo mean in photosynthesis? | light |
| what does synthesis mean in photosythesis? | put together (make) |
| What is the definition of photosythesis? | a plant makes its own food using light energy |
| what does a plant need to carry out photosynthesis? | *CO2*sunlight(light energy)*water *chlorophyll |
| what are a plants main products? | Oxygen,sugar,starch |
| BONOUS QUESTION:What are all the plant cells organelles? | cell wall,cell membrane, chloroplasts, cytoplasm,vacoule,mitochondrion,nucleus |
| BONOUS QUESTION:What are all the animal cells organelles? | cell membrane, vesicle, nucleus, mitochondrion, cytoplasm |
| What do plants need for photosynthesis? | CO2 gas,light energy,water,chloophyll |
| What are the main products of photosynthesis? | oxygen,sugar ,and starches for plants |
| How do plant cells and animal cells differ? | plant cells have a cell wall and chloroplasts |
| What does the stomata do? | let CO2 in,let oxygen and water out |
| What does a nucleus do? | controls what the cell does |
| Do all cells have a nucleus? | no,all cells do not have a nucleus |
| How many diffrent types cells are there? | many |
| What does chloroplast do? | makes food from light energy |
| What is it called when plants store energy? | cellular respiration |
| A mitochondria is also called the__________ | power plant |
| What is the formula for photosynthesis? | Co2+h2o+sunlight+chlorophyll=sugar+oxygen |
| What is the formula for cellular respiration? | sugar+oxygen=Co2+h2o+energy |
| What is transpiration? | water leaving the plant |
| What does the cytoplasm do? | Stores wastes. |
| What are te basic parts of cells? | the cytoplasm,nucleus,cell membrane mitochondrion,and the vacuole |
| What is the mitchondrion's job? | to release energy from the cell |
| What does a vacuole do? | Stores water,energy and wastes in PLANT cells |
| what is the basic unit of structure and function in living things? | cells |
| can you see something microscopic with your eyes?what is the defintion for microscope ? | no,something microscopic can only be seen using a microscope.A microscope is a tool used to see things that can't be seen with the naked eye |
| bacteria cells are what and are not what? | they are singled celled orginisms and has cell walls.they are not organelles,plantcells,animalcells and they do not have nucleus . |
| what is protists? | they are single celled organelles and have nucleus and organelles(not plant cells,animal cells ,or bacteria). |
| Is all bacteria bad? | No, if you eat yogurt or cheese those are both bacteria mixed with milk |
| What do protist have that bacteria does not? | a nucleus and organelles |
| What is transpiration? | water leaving the plant |
| What do plant cells store energy? | sugar and starches |
