Question | Answer |
---|---|
Organism | living thing |
biology | STUDY of living |
All living things... | are made of cells, reproduce, exchange gases, produce waste, regulate their bodies, breakdown nutrients for energy, and respond to stimuli or to their environment |
Taxonomy | the study of classification |
Two scientist that developed the microscope? | Leeuwenhoek and Hooke |
What is the diameter of the field of view on medium power? | 2.0 mm |
What is the diameter of the field of view on high power? | 0.2 mm |
What classifications make up an organisms' scientific name? | Genus and species |
Which level of classification has the most members? | Kingdom |
total magnification on HIGH power | 400x |
total magnification on MEDIUM power | 100x |
The part of the microscope that changes magnification? | objective lenses ** know where this is on microscope |
What part of the microscope changes the amount of light? | diaphragm **know where this is on microscope |
raises and lowers the stage | fine and course adjustment knobs **know where this is on microscope |
parts of an insect | head, thorax and abdomen six legs exoskeleton |
Black worm uses blood to .... | carry nutrients and waste |
Earthworms and black worms have these in common. | segmented bodies, tiny bristles (chaetae/setae) for moving, regeneration, |
The process that happens because an exoskeleton does NOT grow. | molting. Cabbage white butterflies larva molts. |
Do cabbage white butterflies go through metamorphosis? | yes, during chrysalis |
Why do we not release the cabbage white butterflies outside after they come out of chrysalis? | they are an invasive species here. |
Our ponds went through a series of changes. What is this called? | succession |
Life cycle of the cabbage white butterflies. | egg, larva, chrysalis, adult |
Characteristics of asexual reproduction | DNA identical (same) as parents, requires only one parent, budding is an example, most common method of reproduction for blackworms |
characteristics of sexual reproduction | DNA that is different from the parents, creates unique offspring (genetic variation), occurs with fertlization |
What are some reasons that seeds do NOT germinate? | too much water, too cold, not enough water, or a fungus |
Seed leaves that provide energy for a DEVELOPING plant are called ________________. | Cotelydons |
Where does transpiration occur? | in the stomata of a leaf |
What is release by the stomatal unit during transpiration? | oxygen and water |
What do desert plants have to prevent water loss in dry climate? | they have adapted by having a thicker cuticle |
What is transpiration? | water loss through the cuticle of a leaf |
What two processes have to happen for a plant to produce a seed? | First, pollination and then fertilization. |
What is the process that forms a seedling after a dormant seed absorbs water? | germination |
Cross-pollination occurs when pollen from the anther of a plant | goes to the stigma of another plant |
The pigment in a cell that captures the sun's energy for photosynthesis? | chlorophyll (is in chloroplast) |
A rigid outer covering found in most plants cells | cell wall |
Flexible covering that lets substances in and out of the cell | cell membrane |
contains chromosomes, control center of cell | nucleus |
green, performs photosynthesis | chloroplast |
jellylike filler that holds organelles | cell membrane |
Two organelles that are sometimes found in plant cells but NEVER in animal cells | cell walls and chloroplast |
Chromosomes are found in the nucleus and are made of ______________ and ______________. | DNA and protein molecules |
Why do chromosomes duplicate during Interphase? | So that the daughter cells will have the same genetic information after they split. |
Do cells grow between cell division? | Yes, cells grow during Interphase |
What helps the chromosomes move in mitosis? | spindle fibers |
List correct order of the cell cycle | IPMAT (Interphase, prophase, metaphase, anaphase, telophase) |
How many chromosomes do humans have? | Humans have 46 chromosomes. |
What are two important characteristics of a Paramecium? | cilia and oral groove |
What two protists have chloroplast? | Euglena and Volvox |
Vertebrate | an organism with a backbone |
Bacteria belong to _____________ kingdom. | They are found in the Monera kingdom. |
Independent variable | What is being tested or what "I" change |
Dependent variable | the results or what changes because of the experiment |
What kind of graph do you use when showing changes over time? | line graph |
What kind of graph do you use to show a relationship between two things? | Scatter plot |
How was selective breeding used in fast plants? | by replanting only the seeds that flowered and produced seeds the fastest. |
