5th Science Q2
| Question | Answer |
|---|---|
| Heterotrophs | Consume plants and other animals |
| Autotrophs | Produce their own food |
| What does food provide for organisms? | It provides the building blocks for growth, development and system repair (nutrients). |
| What level of consumer are humans? | Humans are 4th level |
| Information that a food pyramid provides that a food web DOES NOT? | Levels & whether its a composer, decomposer, producer and consumer. |
| Digestion | Process of breaking down food into simple chemicals called nutrients. |
| How are human and painted lady butterfly digestive systems similar? | They both have stomachs and intestines |
| Why is digestive system called a system? | It has a ton of interacting parts. |
| What do your mouth and teeth do as their part of digestive system? | Moisten and crush the food to prepare it. |
| What does your esophagus do as its part of the digestive system? | Move the food from the mouth to the stomach. |
| What does your stomach do as its part of the digestive system? | Adds gastric juices to the food. |
| What do the small and large intestine do as its part of the digestive system? | They help release nutrients into the bloodstream that is delivered to every cell in the body. |
| What does the colon do as its part of the digestive system? | Compacts and dehydrates food waste. |
| What do the kidneys do as their part of the digestive system? | Filters cellular waste from the blood and turns it into urine stored in the bladder. |
| What do the rectum & anus do as their part of the digestive system? | Move indigestible material and dead bacteria called feces into the rectum and eliminate through the anus. |
| How are nutrients transported in a plant? | Nutrients are transported from the xylem and the phloem to the cells in the plant. |
| Leaf veins | Pathways found in and on leaves made up of tiny tubes which water and sap flow. |
| Sap | Water carrying different kinds of dissolved plant nutrients / provides food to plant cells that make their own food. |
| Plant tube types: | Xylem and Phloem |
| Xylem | Transport water & minerals from vascular plant roots throughout the entire plants cells. |
| Phloem | Delivers sugar to all the cells and tiniest of roots. |
| 3 Leaf Vein Patterns: | Parallel, Pinmate, Palmate |
| Describe Leaf Pattern Parallel | Numerous veins extending the length of the leaf that all are parallel to one another. |
| Describe Leaf Pattern Pinmate | Feather shaped leaves with one main vein running the length of leaf and smaller veins branching off it. |
| Describe Leaf Pattern Palmate | Shaped like the palm of a hand with several large veins starting from a central point and extending out in several directions and smaller branched out veins. |
| Leaf Classification (3) | Venation patterns, Edges/Margins, Shape |
| Process of Transportation (leaves) | Water is removed from cells and passed into the environment. |
| Outside Investigation (leaves) | Plastic bags placed over leaves of outdoor plants and moisture is found several hours later. Moisture is evidence for process of transportation. |
| How does water get to the cells at the top of the plant? | From the Xylem system |
| How does sugar get to the cells that can't make their own food? | Sap through the Phloem system. |
| How do humans transport nutrients to all the cells? | Through the bloodstream. |
| Tricuspid heart valve | Blood flows INTO RIGHT ventricle into heart FROM body. |
| Pulmonary heart valve | Blood flows FROM RIGHT ventricle as its pumped TO LUNGS. |
| Mitral heart valve | Blood flows FROM LUNGS into LEFT ventricle. |
| Aortic heart valve | Blood flows FROM LEFT ventricle and pumped OUT to body. |
| Human Circulatory System does: | Pumps blood through vessels called arteries, veins and capillaries. |
| Arteries | Blood vessels that carry blood FROM heart to the body. |
| Veins | Blood vessels that carry blood TO heart from the body. |
| Capillaries | Smallest blood vessels where gases, nutrients and waste are exchanged between capillaries and cells in order to survive. |
| Heart and role in the circulatory system | 4 chamber pump made of muscles that pushes blood around in the circulatory system. |
| Right Ventricle function | Pumps blood to the lungs. Blood flows from the lungs into the LEFT side of the heart. |
| Left Ventricle function | Pumps blood to all the cells in the human body. |
| Heart valves function | Act as one way doors making sure blood moves in only one direction. |
| Red blood cells function | Carry oxygen to cells. |
| How do we breathe? | We breathe to exchange gases, breathe in oxygen and release carbon dioxide. |
| Parts of the respiratory system: | Lungs, system of lungs to the outside air and the diaphragm. |
| What is respiratory system function? | Bring oxygen to the red blood cells and get rid of the waste carbon dioxide. |
| Alveoli | Tiny air sacs at end of the bronchioles that receive the waste carbon dioxide from the body's cells. |
| Alveoli function | To transfer carbon dioxide from the red blood cells into air within the sacs. |
