13. The main differences between animals and plant cells are:
(1) Animals do not have the ______ that plant cells have;
(2) Animals do not have ______ in their bodies and cannot carry out photosynthesis;
(3) Animals are generally free to ______;
(4) Animals are free from the outside world . Stimulus response ______.
Answer:
(1) Animals do not have the cell walls that plant cells have;
(2) Chloroplasts are unique to plant cells and are the place where plants perform photosynthesis. Chlorophyll in chloroplasts can absorb light energy, convert light energy into chemical energy, and convert carbon dioxide and carbon dioxide. Water is transformed into organic matter, but animals do not have chloroplasts and cannot perform photosynthesis;
(3) Since animal cells do not have cell walls, animals can generally move freely, and their movements are flexible and sensitive;
(4) Because animals do not have cell walls that plant cells have, Therefore, animals are sensitive to external stimuli.
So the answer is:
(1) cell wall;
(2) chloroplast;
(3) movement;
(4) sensitive
