Answer 1

answer of 7 question


Onion Cell

An onion is a multicellular (consisting of many cells) plant organism.As in all plant cells, the cell of an onion peel consists of a cell wall, cell membrane, cytoplasm, nucleus and a large vacuole. The nucleus is present at the periphery of the cytoplasm. The vacuole is prominent and present at the centre of the cell. It is surrounded by cytoplasm. The presence of a cell wall and a large vacuole are indicators that help identify plant cells, such as seen in the onion peel.

Human Cheek Cell

As in all animal cells, the cells of the human cheek do not possess a cell wall. A cell membrane that is semi-permeable surrounds the cytoplasm. Unlike plant cells, the cytoplasm in an animal cell is denser, granular and occupies a larger space. The vacuole in an an animal cell is smaller in size, or absent. The nucleus is present at the centre of the cytoplasm.The absence of a cell wall and a prominent vacuole are indicators that help identify animal cells, such as cells seen in the human cheek.

Answer 2

ans 7 is onion peel cell is a plant cell...and human cheek cell is an animal cell...and now we can easily differentiate between plant and animal cell....firstly...we will discuss about plant cell...outer member of plant cell is cell wall which is absent in animal cell.. nextly...the plasma membrane of plant cell is made up of cellulose while the plasma membrane of animal cell is made up of phospholipid bilayer...plant cell consists of plastids which are not present in animal cells....plant cells are generally larger in size than animal cells...plant cells contain permanent large sap vacuole while animal cell contain small,temporary and many vacuoles...golgi appartus in plant cell is in simpler form called dictyosomes...while animal cells have single highly compact(complex) and prominent golgi apparatus...animal cells have centrosome and centrioles while plant cell do not have centrioles and centrosome...
