Question

1. from the images above, come up with three statements to describe the main features that link cells and living things. (a) (b) (c) 4. for each of the cells listed below, use the matching image above to explain why the cell is prokaryotic or eukaryotic: (a) human cheek cells: (b) paramecium: 5. use your reasons from question 3 above to explain why each of the objects below is living or non - living:

Explanation:

(a) All living things are made of cells. Cells are the basic structural units of life as seen in the images of single - celled organisms like Paramecium and the cells in a plant.
(b) Cells carry out life processes. For example, Didinium captures and eats Paramecium, showing the process of obtaining nutrients which is a life - process.
(c) Cells contain genetic material. The presence of chromosomes in the dividing plant cells indicates the presence of genetic information necessary for life.
For 4(a), Human cheek cells are eukaryotic because they have a well - defined nucleus and membrane - bound organelles (not shown directly in these images but known from general cell biology).
For 4(b), Paramecium is eukaryotic as it has membrane - bound organelles as seen in the image of organelles inside Paramecium.
For 5, without the list of objects, we can't provide specific answers, but in general, if an object has cells and can carry out life processes like those described in 3, it is living; if not, it is non - living.

Answer:

(a) All living things are made of cells.
(b) Cells carry out life processes.
(c) Cells contain genetic material.
4(a) Human cheek cells are eukaryotic due to having a well - defined nucleus and membrane - bound organelles.
4(b) Paramecium is eukaryotic as it has membrane - bound organelles.
