In experiment 3, what was the appearance of the elodea cells in aquarium water a: the chloroplasts were located mostly from the center of the cell b: the chloroplasts were located mostly at the periphery of the cell c: the cell membrane was pressed against the cell wall d: the cell membrane shriveled and pulled away from the cell wall

The correct answer will be option-B.

Explanation:

Elodea is the aquatic plant which contains all the organelles like a nucleus and cell wall which gives the box-like appearance to the cells. The elodea cells lack a central nucleus.

In the given question, the chloroplast organelle associated with the photosynthesis in plants is observed at the periphery in every plant cell. Few chloroplast cells are distributed in the center.

Thus, Option-B is the correct answer.

phylogenetic tree is the tree of life or evolution tree. it shows the different branches of evolution. the sequence goes like tissues - coelom - backbone - endoskeleton - segmentation

condensation. good luck!
