The stamen is where pollen is produced. The stamen is where the eggs are stored. The stamen is where the seed germinates. The stamen is where fertilization takes place. A; have students eliminate other options with reasoning. B- eggs are produced in the ovules; C-seeds are germinated in the soil (on the ground), D- fertilization takes place in the ovary (ovule)

The following structures are involved in the process of photosynthesis The following structures are involved in the process of photosynthesis. Which one do you believe is most important to this process? Use reasoning to defend your answer. Leaf Stomata Chloroplast Chlorophyll There is no correct answer here.

The vast majority of plants function best when there is ample water and temperatures are well above freezing throughout the year. Plants, unlike animals, do not have the luxury of body insulation or locomotion. Consequently, as the temperatures decrease in the winter many plants respond by losing leaves and slowing growth.

Should I water the plants with something other than water? Your neighbor had to go out of town for three weeks. You agreed to water her plants every few days. She closed the curtains so people could not see into the house. The only window that was NOT covered was in the kitchen. After two weeks, you noticed that the only healthy plant was in the kitchen. What question could you ask yourself to find out why the other plants do not look healthy anymore?   Does the amount of sunlight a plant receives affect how well the plant grows? Should I repot the plants into bigger pots to give them more room to grow? Should I water the plants with something other than water? Do I need to water the plants more often to make them grow better? A
