hypertonic
Which structure will form when a primitive cell engulfs an aerobic bacterium? mitochondria chloroplast nucleus cell membrane
mitochondria

It provides support.
Based on the data in the graph, which would most likely happen if the paramecium were placed in distilled water? The contractions would increase. The contractions would decrease. The contractions would cease altogether. The contractions would establish dynamic equilibrium.
The contractions would increase.
Which organelle in the table is correctly matched with its function? nucleus endoplasmic reticulum Golgi apparatus lysosome
nucleus
According to the endosymbiotic theory, which cellular process was involved in the evolution of mitochondria and chloroplasts? symbiosis phagocytosis endosymbiosis photosynthesis
phagocytosis
What is shown in the image? prokaryote eukaryote chloroplast mitochondrion
prokaryote
Which organelle in the table is correctly matched with its function? lysosome vacuole mitochondrion ribosome
ribosome
Two cells in the same organism differ only in the number of chloroplasts they contain. The first cell has multiple chloroplasts, and the second cell has very few. What would most likely characterize these cells? There would be no difference between the functioning of the cells because the chloroplasts are not essential cell structures. The second cell would become larger because it would have fewer chloroplasts regulating its size and shape. The second cell would shrink because it would not be able to store water and maintain cell shape. The second cell would not be able to produce as much food because it could not capture very much sunlight.
The second cell would not be able to produce as much food because it could not capture very much sunlight.
Chlorophyll is found in plant leaves and absorbs light from the sun to enable plants to perform photosynthesis. Magnesium is an important component of chlorophyll. The concentration of magnesium ions is higher in the root-hair cells of plants than in the soil. Which mechanism of ion uptake would best enable a plant to produce a steady supply of chlorophyll? osmosis diffusion passive transport active transport
active transport
Which organelle can be compared to a security guard who decides whom may enter a building and whom may not? cell membrane cytoplasm endoplasmic reticulum mitochondrion
cell membrane
Which organelles are not found in plant cells? vacuoles mitochondria chloroplasts centrioles
centrioles
Shannon is making a Venn diagram to organize the characteristics of cell walls and cell membranes. Which pair of characteristics both belong in the two areas of the Venn diagram that do not intersect? helps with communication; contains mostly cellulose contains mostly cellulose; forms the outer layer of animal cells is found in plant cells; is found in animal cells is semipermeable; found in animal cells
contains mostly cellulose; forms the outer layer of animal cells
Which is a function of the cell membrane? performs photosynthesis controls what enters and leaves the cell produces proteins provides energy to the cell
controls what enters and leaves the cell
Which organelle, is found in both plant and animal cells?
the cell membrane
