JT's vascular plants
5th grade science
| Question | Answer |
|---|---|
| Waht are the 3 main parts of vascular plants? | roots, stems and leaves |
| What is the purpose of the root system? | holds the plant in place and stores food |
| The stem and leaves form what system of the plant? | stem and leaves form the shoot system |
| What is the purpose of the shoot system? | is to support the plant,to transport materials and to produce food. |
| What are the 2 types of vascular plants? | seedless and seed |
| How do seedless plants develop? | from spores |
| What is a spore? | a single cel tlhat can develop into a new plant that is exactly like the plant that produced it. |
| What is a seed? | contains an undeveloped plant, stored food and a protective covering. |
| How do seed plants make more of themselves? | when male and female cell are joined. |
| How do seedless plants make more of themselves? | reproduce through spores. |
| What is an angiosperm? | a seed plant that produces flowers. |
| Give 3 examples of an angiosperm. | Fruits, vegetables, and grains |
| What is a gymnosperm? | a seed plant that doesn't produce flowers. |
| Give an example of a gymnosperm. | Evergreen |
| What are flowers? | The reproductive organs of angiosperms |
| What is the make part of a flower called? | stamen |
| what does the stamen produce? | pollen grains |
| What is female part of the flower called? | pistil |
| How and why do flowers attract animals? | Flowers have bright colors, scents and nectar to attract animals (insects, birds, small mammals) |
| What is it called when the pollen and egg cell join to form a seed? | Fertilization |
| What is the purpose of fruit? | protects the seeds inside the flower |
| Name 3 ways seeds are dispersed? | animal fur and droppings, through special winged structures seeds might have |
| What is the job of a root in transporting things for the plant? | store food anchor the plant and carry water anf minerals up the stem to the leaves. |
| What is the job of a stem? | develop buds and shoots and usually grows above the ground. It houses the transport system. |
| What is the job of a leaf? | a leaf releases gases into the air and produces sugar. |
| What connects the leaf to the stem or branch? | the petiole connects the leaf to the stem or branch. |
| What do leaves use to produce sugar? | water and carbon dioxide |
| what is the job of the xylem? | to move water and minerals up from the roots. |
| what is the job of the phloem? | to move sugar produced in the plant's leaves to the other parts |
| What is the name of the place where xylem and phloem cells are produced? | cambium |
| what is the function of bark> | protective layer around the tree. |
| what do lighter rings tell you? | formed during spring whe good conditions for growht occur. |
| What do darker rings tell you? | grow during autumn when there is little water. |
| what do larger rings tell you? | there was alot of rainfall that year. |
| Describe a taproot | one large root within a few branching hairy roots |
| 3 examples of taproots are | dandelions, beets, carrots |
| where to taproots tend to grow | deep into the soil |
| describe fibrous roots | thing branching roots |
| example of a fibrous root | grass |
| describe prop roots | grow like fingers out of the bottom of a stem |
| example of a prop root | corn |
| describe aerial roots | never touch the ground |
| example of an aerial root | ive and orchids |
| What is photosynthesis? | food making process of plants using energy from sun and water, absorbed by roots and carbon dioxide from the air to make food |
| what is needed for photosynthesis to occur | sun, carbon dioxide (co2) and water (h20) |
| what does carbon dioxide enter the plant? | through the stomata |
| what happens to the stomata when there is little water? | guard cells close and preserve water |
| what happens to the stomata when there is too much water? | guard cells open |
| where does photosynthesis take place | in the choloroplasts |
| what is the name of the chemical that absorbs light energy? | chlorophyl |
| photosynthesis creates sugar for teh plant What is the sugar used for? | for food |
| what is teh waste plants make? | oxygen |
| what is the chemical equation for photosynthesis? | 6CO2 + 6H2O + energy > C6H12O6 + 6o2 |
| what is the purpose of photosynthesis and Respiration cycle? | provide energy to plants and animals |
| What is the name of the sugar plants produce during photosynthesis? | carbohydrate |
| what is a carbohydrate made from? | carbon, hydrogen, and oxygen |
| Why do animals also depend on photosynthesis? | because of the food chain |
| what do you call it when animals breathe in oxygen? | cellular respiration |
| when would an animal of plant use oxygen? | when the cell needs energy. |
| Why are Photosynthesis and respiration are opposites? | cellular respiration is co2 + h2o, photosynthesis uses co2 and h2o to produce sugars |
| Where does cellular respiration occur in cells? | mitochondria of a cell |
| What is the energy for? | help plant and animal cells grow and repair themselves |
| what do mitochondria use oxygen for? | breaks down stored carbohydrates to release energy. |
| What is the released energy in the mitochondria called? | ATP is the energy released from mitochondria |
