• Answer:

    A plant cell as seen under electron microscope

  
  Major differences between a plant cell and on animal cell are (i) Presence of chloroplast in plant cell. (ii)Presence of large central vacuole in plant cell. (iii) Presence of cell wall.

• Answer:

    A diagram of an eukaryotic nucleus is as given  

  
    The major differences between prokaryotic and prokaryotic nucleus is that a prokaryotic Nucleus (i) is undifferentiated                                                     (ii) is not bound by nuclear membrane (iii) does not contain chromosome                           (iv) does not possess nucleolus and nucleolus,

• Answer:

    The major differences between rough and smooth endoplasmic reticulum are

  Smooth Endoplasmic Reticulum	Rough Endoplasmic Reticulum
  SER has no ribosomal particles on the surface, hence look smooth.   It helps in manufacturing of lipids and fat molecules.	RER has particles of ribosome on the surface, therefore are rough in texture. They are the sites of protein synthesis.

  Endoplasmic reticulum synthesizes lipids (smooth endoplasmic reticulum) and proteins (rough endoplasmic reticulum) which are responsible for formation of membrane. Thus, they help in membrane biogenesis.

• Answer:

    (a) Dry apricots when placed in pure water swell due end osmosis (inward movement of water) and later when are transferred sugar solution exosmosis (outward movement of water) occurs and they shrink again. (b) When a Red Blood Cell is placed in concentrated saline solution exosmosis occurs and the RBCs shrink due to excess loss of water. (c) Breaking of the plasma membrane leads to the scattering of the ceil organelles as it forms the basic supporting unit of the cell. (d) When Rheo leaves are boiled in water first and then a drop of sugar syrup is put on it, osmosis does not occurs, due to the death of the cells of the leaf. This shows that selective permeability is property of living plasma membrane. (e) Golgi complex helps in the package, storage and transfer of proteins synthesized by ribosome?s. Thus, when ribosome?s are removed the cell will not function properly.

• Answer:

                              

  
                  (i) Cell wall in the characteristic feature of plant cell. (ii) Chloroplast is found in plant cell which helps in photosynthesis in plants, Animals cannot synthesize their own food because chloroplast is not found in the animal cell. (iii) Large vacuoles are found in plant cell which contains excretory waste of plant cell Animal cell do not possess vacuoles, if present these are of small size.
