WebThe Study of Life Recall 1. The potato tuber cells are rounder and less packed together because they are for food storage (starch) and do not need to function as cohesively together as the onion epidermal cell, Why is the central vacuole not as prominent in the potato tuber cells relative to the Elodea leaf cells, The elodea leafs are constantly exposed to a high concentration of water so it's more critical that elodea can efficiently remove excess water from the cell, plastids that contain pigments other than chlorophyll - various places in the cell, usually a cluster around the nucleus though, Do tomato pulp cells more closely resemble those of the potato or of the onion, They more closely resemble the potato cell in both their round shape and their higher concentration of plastids than any other organelle, Compare the size, shape and color of chromoplasts with chloroplasts and amyloplasts, - Chromoplasts are red and circular and a medium size - Chloroplasts are green, circular, large and numerous - Amyloplasts are the same color as the cell and a discoid/round shape and relatively small, small extensions of the plasma membrane that extend through holes in the cell wall, an particularly thin area of the cell wall where plasmodesmata sometimes cluster.
