Chp 2 Life Cycles
| Question | Answer |
|---|---|
| stages that an organism passes through from egg or spore to reproducing adult | life cycle |
| a decomposer that usually reproduces through spores | fungi |
| structures on the underside of a mushroom cap | gills |
| the set of instructions that control an organism's characteristics and life processes | genetic material |
| what is a generation | one complete life cycle |
| how long does it take a bacterium to go through its life cycle | 20 minutes |
| the science word for consisting of only one cell | unicellular |
| give an example of where bacteria are found | {{Recall class discussions & refer to science notebook}} |
| science tool needed to see bacteria | microscope |
| the first stage in a bacterium life cycle | copy genetic material |
| scientist who studies fungi | mycologist |
| example of unicellular fungus | yeast |
| organism in its early stages of development | embryo |
| nutrient rich structure inside a seed (food for the embryo until it can make its own food) | cotyledon |
| the outer protective covering of a seed | seed coat |
| the male structure of a flower | stamen (male = staMEN) |
| the female structure of a flower | pistil |
| what does the anther produce | pollen |
| what does the ovary contain | egg cells (ovules) |
| the process when a pollen grain unites with an egg cell | fertilization |
| the process where pollen is transferred from anther to stigma by pollinators | pollination |
| what does the fertilized egg of a plant become | a seed |
| what develops around the seed (from the ovary) | fruit |
| what do we call a young PLANT | seedling |
| give an example of a pollinator | {{Recall class discussions & refer to science journal}} |
| True or False: All organisms have the SAME life cycles. | False |
| the best way to get rid of bacteria on our hands | good hand washing |
| what does germinate mean | to begin to grow or develop |
| the job of fungi | decomposing |
| 3 basic parts of a bean seed | seed coat, cotyledon, embryo |
| Pollen grain contains half of the genetic material and the egg contains the other half of the genetic material needed to make a new plant. | |
| True or False: All organisms go through life cycles. | True |
| stages of bacterium life cycle | 1) copy genetic material; 2) cell elongates; 3) build a cell wall; 4) divide into two new cells |
| what is difference between how a fungus and a plant reproduce | {{Recall class discussions & refer to science journal}} |
| Be able to label the parts of a flower & be familiar with the job/function of each part | {{Recall class discussions & refer to science journal}} |
| How do we see God's purposeful design in life cycles? | {{Refer to Genesis 1) |
