Answer 1

1 prokaryotic cell is a simple cell with out a well defined nucleus. The chromosomal material is freely floating in the cytoplasm. for example - bacterial cells.
____________
2 eukaryotic cells has a well defined and membrane bound nucleus. It's a complex cell. example - plant and animal cells
__________________________
3 plant cell - rigid cell wall, large vacuoles, chloroplast is present for photosynthesis
animal cell - cell wall absent, small or no vacuoles, photosynthesis is not carried out so chloroplast is not present
_____________________
4 vacuole acts as storage sacs in the plant cells. it occupies most of the area in the cytoplasm of the cell. it is enclosed by membrane and contains fluid.
_______________________
5 mitochondria are power house of the cell. they help in protein synthesis in the cell.
________________________________
6 contents of plant cell wall, the major carbohydrates are cellulose, hemicelluloses and pectin. The cellulose microfibrils are linked via hemicellulosic tethers to form the cellulose-hemicellulose network, which is embedded in the pectin matrix.
______________
7 genes are the functional segment of DNA
__________________________________
8 They both have their own DNA and ribosomes, and are self-replicating. They both have a double membrane.
______________________
9 chloroplast - photosynthesis
nucleus - contains genetic information
chromoplast -  are found in fruits, flowers, roots, and stressed and aging leaves, and are responsible for their distinctive colors. 
leucoplast - are colorless plastids. found in endosperm, tubers, roots and other non-photosynthetic tissues of plants. They serve various functions, for example, storage of starch, lipids, or proteins.

10 mitochondria and plastids
_______________________
11 endocytosis is the process of taking in of matter by a living cell by invagination of its membrane to form a vacuole. (amoeba )
________________________________
12 In biology, cell theory is a scientific theory which describes the properties of cells. These cells are the basic unit of structure in all organisms and also the basic unit of reproduction. it was proposed by Theodor Schwann and Matthias Jacob Schleiden.
