1. the lysosome is responsible for?

a. holding genetic material for cell division

c. digestion of food and other molecules
d. protein synthesis

1. eukaryotic cells are those with membrane - bound organelles such as?

a. nucleus
b. ribosomes
c. lysosomes
d. all of the above
e. none of the above

1. where are organelles located?

a. nucleus
b. centriole
c. cytoplasm
d. lysosome

1. despite the differences in size and shape between cells and cell types, all cells have cytopla

a. cell wall
b. cell membrane
c. mitochondria
d. nucleus

1. which organelle converts food (glucose) into a form that the cell can convert into a useabl (atp)?

a. mitochondria
b. nucleus
c. chromosomes
d. chloroplast
e. nucleus

Explanation:

1. The cell theory states that all living things are composed of cells, cells are the basic unit of life, and new cells are produced from existing cells. Cells are not the smallest known substances.
2. Eukaryotic cells have a nucleus, while prokaryotic cells do not. Bacteria are prokaryotes and viruses are not cells.
3. Lysosomes are responsible for the digestion of food and other molecules.
4. Eukaryotic cells have membrane - bound organelles like the nucleus. Ribosomes are not membrane - bound and lysosomes are just one type of membrane - bound organelle.
5. Organelles are located in the cytoplasm.
6. All cells have a cell membrane. Not all cells have a cell wall (e.g., animal cells), mitochondria (prokaryotes lack mitochondria), or a nucleus (prokaryotes).
7. Mitochondria convert food (glucose) into ATP.

Answer:

1. b. Cells are the smallest known substances
2. b. Eukaryote
3. c. Digestion of food and other molecules
4. a. Nucleus
5. c. Cytoplasm
6. b. Cell membrane
7. a. Mitochondria
