A spore is a small structure, usually a single cell, produced by plants, fungi, and some microorganisms. In the right environment, a single can develop into a new, individual organism
During observations of soil samples, Eientists find tiny structures that to spores
Which could the Kientists use that would determine if the* tiny structures are
A) Test them for chemicals normally found in living cells
Rationale: Chemicals found in living cells, such as water or salt, might also found in structures or conditions life
B) Place them in water and if they change in or mass Rationale: Many nonliving things can change or mass when plæed in water
C) Observe whether they go through the steps of cell division to form new cells
Rationale: Living cells come from existing cells
D) Observe whether they are of atoms by using a microscogk
Rationale: Nonliving things are also composed of atoms
Correct Answer
C) Observe whether they through the steps of cell division to form new cells

Jade places a fresh, thin slice of onion on a microscope slide to look for evidence that an onion is made Of cells
Describe two observations Jade could make to provide evidence that an onion is made Of cells
Correct Answer
Answers may vary
Explanation
Observations that Jade could make to provide evidence that an onion is made of cells include seeing
cell walls. The [rectangular] cell walls surround rows Of units (bu-like structures) [cells] that are attached to one another. [Onions are plants; so. their cells have a cell wall to provide structural support.]
cell membranes. Thin membranes within the cell walls contain the cell organelles
nuclei. Each cell has a nucleus that may be seen with a light microscope. [Some cells may have a nucleus that is in the process of mitosis and actively dividing.]
cell division. Recognizing the different stages of cells dividing [mitosis] is evidence that an onion is made Of cells
