Science study 3
| What are three differences between monocots and Dicots ? | number of cotyledons:shape of leaves :roots |
| What is the function of the roots? | supply plants with water and nutrients |
| What do plants need to do photosynthesis ? | carbon dioxide,sunlight |
| What gas is released from plants during photosynthesis? | oxygen |
| What pigment is responsible for a plant's green color ? | chlorophyll |
| What does cellular respiration need to produce energy ? | water,carbon dioxide ,ATP (energy) |
| What cell part captures energy from the sun to make food? | chloroplast |
| Where does the energy that starts the process of photosynthesis come from ? | gluecose |
| What is the male part of the flower? | stamen |
| What is the female part of the flower? | pistil |
| What part of the flower contains the ovules? | ovary |
| During cellular respiration what do plant cells use to produce energy from food | oxygen |
| Why is photosynthesis important? | all food chains begin with photosynthetic organisms |
| What is fertilization? | the joining of egg and sperm |
| What does an ovule turn into after fertilization? | seed |
| To be considered a food what does a substance must provide? | energy |
| What are 6 things needed for a plant to grow and develop? | sunlight,gluecose,air,water,temperature,minerals |
| If a plant gets light from only one direction ,what is the likely direction of the shoots? | grow toward |
| If a plant tipped on its side ,the shoots will most likely grow in what direction ? | grow up away from the pull of gravity |
| if a plant bends toward light ,it is showing what kind of tropism? | positive phototropism |
| Roots growing toward the center of the earth are showing what kind of tropism? | positive gravitropism |
| Why do leaves turn orange and yellow in the fall? | the amount of chlorophyll is not being replaced so other color pigment show |
| Why do deciduous trees shed their leaves? | to preserve water during colder months when rain is less |
| What is the function of the fruit that surrounds seeds? | protect the seeds |
| Why are plants green in color ? | green wave lenghts of light are reflected |
| What is the purpose of petals? | to attract pollinators |
| What is the purpose of cotyledons? | to store energy for the developing plant |
| What are sperm and eggs? | sex cells |
| What is an embryo? | the early stage of an organisms developement |
| A collection of specialized cells is called? | tissue |
| A group of tissues that carry out a special function is called? | an organ |
| What do animals use to get from one place to another? | movement |
| What is an organism that eats other organisms called? | consumer |
| Do animals have prokaryotic or eukaryotic cells ? | eukaryotic |
| Do animals have cells have a cell walls? | No |
| Are animals unicellular or multicellular? | multicellular |
| What is an invertebrate? | an organism that does not have a backbone |
| What is an vertebrate? | an organism that does have a backbone. |
| What is a heterotroph? | an organism that does not produce its own food |
| What is Tropism? | a plants growth in response to a stimulus |
| What is phototropism? | plants growth response to light |
| What is thigmotropism? | plants growth response to touch |
| What is gravitropism? | plants growth response to gravity |
| Anther | That part of the stamen where pollen is produced |
| Stigma | The sticky tip of the pistil |
| Pollen | male sex cells that can be carried by the wind |
| Flower | That part of the shoot of a higher plant specially modified for reproduction |
| Ovary | the part of the flower where female sex cells are made |
| Sepal | outermost leaves modifies to protect the bud |
| Petal | brightly colored leaf shaped parts of a flower |
| transpiration | the loss of water from leaves |
| cellular respiration | the process by which plants get energy from food |
| chlorophyll | green pigment found in plant cells that capture energy from sunlight |
| photosynthesis | the process by which plants make their own food |
| dormant | describes an inactive seed of plant part |
| pollination | happens when pollen is moved from the anthers to the stigma |
| decidous plants | plants that lose all of their leaves at about the same time every year |
| evergreen plants | plants that keep some of their leaves year round |
| During photosynthesis what gas do plants release? | oxygen |
| During cellular respiration what do plant cells use to produce energy? | oxygen |
| When seasons change some plant respond to changes in the amount of chlorophyll in leaves | the length of day and night |
| after fertilization in a flower the ovary developes into a? | fruit |
| where does germination occur | underground |
| how many different minerals are needed by a plant | 13 |
| what is a brassica rapa | wisconsin fast plant |
| ow long does it take for a fast plant to go through a life cycle | 6 weeks |
| what 3 things does an embryo contain? | stem,roots,leaves |
| what gives roots more surface area? | root hairs |
