Answers
1. Virus canbe consider to be alive as they depend on host to replicate their RNA & DNA.They are much smaller than cells.
But cell theory states " cells areally basic and funtalented unit of life." But virus is not made up of cells. But it is a living.
2. Haploid cells have 46 chromosomes that is 23 pairs.
3. Passive transport- refers to the movement of substances from one part of cell to another without involvement of energy.
Active transport- It is a fast processband requires energy(ATP)to transport molecules.it can transport molecule against the concentration gradient and needs transport protein.
4. It provides define shape to the cell.It prevent cell from drying.
5.An organellesnisha subcellular that has a specific function.The activities depends upon structure including organelle and plasma membrane.
6.The aqueous component of cytoplasm of a cell, which various organelle and particles are suspended.
7.Dictyosome are stacks of flat membrane bound cavities that together comprise the golgi apparatus protein ate stored, modified, stored, and packed into vesicles.
8.The nerve cell also known as neuron. combine and collect the information received from other sensory cell and from an output that serves as an inputb for the nerve cell.
9.Cis faces - Convex in shape, Faces the endoplasmic reticulum , Receives vesicles from the endoplasmic reticulum and receive immature or unmodified protein.
Trans face- Concave in shape, faces the cytoplasm, vesicles exist the golgi apparatus from this side, modified protein leaves the golgi apparatus.
10.A membrane which bound the cheif vacuole of the plant cell.
