                                                            The plants flowers didn't show that much variation. They mostly look the same. The plant's leaves have a lot of variation. Most of the leaves on the plants are different sizes and the outline is sometimes different. Plant 1 has a leaf height of 16 cm and width of 14 cm the stem size is 30 cm. Plant 2 has a leaf height of 14 cm and a width of 8 cm, the stem size is 14 cm. Plant 3 has a leaf height of 26 cm and a width of 26 cm, the stem size was 32 cm. Mostly now these days, people do selective breeding which is when people select certain types of genes for plants like brassica oleracea to make them better. Artificial selection is when people select certain phenotypes. Some mutations could contribute to the plants looks and genotypes. This could help with the plants ...

Here is a view at (2x) on the microscope. Here is a part of a plant that is called the carpel. The carpel has a stalk called the style. There is a sticky tip of the carpel that is called the stigma. This part of the carpel is sticky which means it can get pollen sticking to it.  We are using the brassica orleracea flower. This is a picture of the whole flower. You can see the pedals, stem, stamen, and the carpel.  This picture shows all the parts needed for reproduction. This flower in particular has both a stamen and a carpel.  This part of the flower has all the parts stripped away except the ovary. The sliced open ovule shows, the ovaries. These ovaries are immature, unfertilized seeds. The ovules are inside of the ovaries. That's what's inside of the ovaries.  Here is a view at (2x) on the microscope. This is the stamen. It is a male part of the flower. There is a stalk that's called the filament. This is the base of the flower that is coming up ...

  Which part (anatomy) or characteristic of the Brassica oleracea plants seems to exhibit the most variation (greatest number of different forms)? Which part or characteristic of the Brassica oleracea plants seems to show the greatest range of variation (biggest difference between one extreme and its opposite)? Use and include data collected from multiple measurements to support your answer. The characteristic of the Brassica oleracea plants that seem to exhibit the most variation is the ratio of length to width size of the leaves on the variety of plants. for example one of the plants the ratio from length to width of the leaf is 1.14 cm, another leaf's ratio of length to width is 1.75 cm, and the last plants' leaf is .93 cm. this shows a great variety and most variation in terms of traits of the plants. the greatest range of size between the ratio of the leaves is .93 cm compared to 1.75 cm. that is a .82 cm difference between ratio of leaf size between the plants...
