dissimilarities with animal

Answers
Answer:
Similarities:-
Both plant and animal cells are surrounded by a cell membrane composed of lipids and proteins.
Membrane bound nucleus is present in both cases.Nucleus has 4 components:-Nucleur envelope,nucleoplasm,nucleolus,chro-matin fibres.
Membrane-bound cell organelles like mitochondria,golgi body, endoplasmic reticulum,vacuoles,etc are present in both plant and animal cells.
80s type of ribosomes are present in both cell types.Ribosomes occur both freely in the cytoplasm as well as they remain attached to the endoplasmic reticulum.
Cytoskeleton is present in both plant and animal cells.
Double-stranded helical DNA present in both cell types.
All the 3 types of RNA viz. m-RNA,r-RNA and t-RNA occurs in both the cells.
Differences:-
Cell wall is present only in plant cells and absent in case of animals.
Chloroplasts present in plant cells whereas absent in case of animals.
In plant cells,large central vacuoles are present but in animal cells vacuoles are very less in number and small in size.
Lysosomes occur in animal cells only and not in plant cells.
Centrioles and centrosomes present in animal cells but absent in case of plants.
In case of animals,reserve food material is glycogen whereas in plants it is starch.
Photosynthesis occurs only in plant cells containing chlorophyll but not in animal cells.
During cell division, spindle formation takes place through microtubules in plant cells,but in animal cells it takes place through aster formation.
In plant cells, cytokinesis or the division of the cell is centrifugal type and a cell plate is laid down in the cytoplasm during division. Whereas in animal cells,cytokinesis is centripetal type.
Answer:
u can simply write the difference between plant and animal cell. it is available in many books
Explanation:
in the differences there are featured of both of the cells
