Question

1. (2) What is "vitalism?" What kind of evidence eventually killed this theory? 2. (4) Compare prokaryotic and eukaryotic cells in terms of size and structures. Give examples of each 3.(4) Compare features found in plant vs. animal cells that would allow you to tell them apart under a light microscope 4. (4) For each of the types of transport shown in the figure below, identify is this transport active or passive? is this transport carrier- or non-carrier mediated? what is this type of transport called? give an example of something in a cell transported this way Please label in your answer A,B,C and D so l know which part of the figure you are referring to Fluid Plasma Membrane Cytoplasm Material to be secreted Vesicle ATP @d

Explanation / Answer

VITALISM:

All the functions of a living organism are due to an unknown vital principle distinct from all chemical and physical forces.

Prokaryotic cell

Eukaryotic cell

Not present

contain membrane-bound organelles, such as the nucleus

DNA content is low

DNA lies inside the nucleus, mitochondria, and plastids

DNA is circular

DNA is linear

Mitochondria absent

Mitochondria present

Ribosomes are 70s

Ribosomes are 80s

Endoplasmic reticulum absent

Endoplasmic reticulum present

Golgi aparatus present

Golgi aparatus absent

Plant cells

Animal cells

Have cell walls, one large vacuole per cell, and chloroplasts

Have a cell membrane only and several smaller vacuoles

Centriole is not found

Have a centriole
