Pcells-Size less than 10 micrometers Ecells-size more than 10 micrometers

42
Q

What is the difference between plant and animal cells in regards to exterior of the cell?

A

Pcells- exterior of cell includes an outer cell wall with a plasma membrane just inside Acells- exterior of cell includes only a plasma membrane, no cell wall

43
Q

What is the difference between plant and animal cells in regards to chloroplasts?

A

Pcells- chloroplasts are present in cytoplasm Acells- no chloroplasts

44
Q

What is the difference between plant and animal cells in regards to vacuoles?

A

Pcells- possess large central vacuoles Acells- vacuoles not ususlly present, or very small

45
Q

What is the difference between plant and animal cells in regards to carbohydrates?

A

Pcells- store carbohydrates as starch Acells- store carbohydrates as glycogen

46
Q

What is the difference between plant and animal cells in regards to centrioles?

A

Pcells- do not contain centrioles within a centrosome area Acells- contain centrioles within a centrosome area

47
Q

What is the difference between plant and animal cells in regards to cell shape?

A

Pcells-because a rigid cell wall is present, this cell type has a fixed angular shape Acells- without a cell wall, this cell is flexible and more likely to be rounded shape

48
Q

What are the exceptions to cell theory?

A

1) Viruses cannot metabolize or reproduce on their own 2) Skeletal muscle and some fungal hyphae are not divided into cells but have a multinucleate cytoplasm.
