Mitochondria = known as the powerhouses of the cell.
They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell.
Answer:
In both animal and plant cells. ... Only in plant cells. Mitochondria. Produces a usable form of energy for the cell.
Yannick's class measured the width of one leaf serval times the values that the class recorded included 10 mm 8 mm 15 mm 5 mm 13 mm. The several different widths indicate that the class lacked the understanding of the word 'width' of the leaf and a standard procedure to make the measurements. Since leaf has two axis of making measurements, along the vein and across the vein. The measurements made along the vein would be greater than that of the across the leaf stem. Also the point of measurement of the width across the vein would vary as leaf tappers by the tip. Hence they should have been instructed to measure the width across the vein by folding the leaf into two halves, so as to make the readings more relevant.
The F1 generation differed from the F2 in the Mendel's experiments in that all the F1 generation showed the dominant phenotype, however only three- fourths or three quarters of the F2 generation did. This is because all the F1 generation were heterozygous and thus the dominant phenotype was expressed, while in the F2 generation there was a mixture of homozygous dominant, homozygous recessive and heterozygous. Therefore, the heterozygotes and the homozygotes dominant showed a dominant phenotype.
Transport proteins require energy because they are pumping materials. Without energy, they won't function and we will have huge problems in our body.
I hope this helps! :D
