Question

A Tour of the Cell
While taking care of his yard, my inquisitive 10 year old nephew asked me why humans don't wilt when we get dehydrated. Explain to him how human and plant cells are similar, but different enough to experience different effects from lack of water. Describe several structures for each organism's cells, along with analogies to help him understand what you are talking about. A Tour of the Cell

Explanation / Answer

When plant cell get dehydrated, the cell gets die or we an say that the plant goes under wilting.but this wilting either temporary or permanent.temporary wilting gets managed by dewatering the plant but permanent wilting leads to death of plant. In plants the cell consist of large vacuole as compared to animal cell. Large vacuole consist of large amount of water. After dehydration the vacuole gets empty and finally the cell fie. Or metabolic inactive .

In case of animals as human there. Is no wilting as cell other cell sap consist of water even in dehydration . Metabolic activity of cell ceases.

Plants and animal cell consists of different organelles-

Cell wall- present in plants. Helps in maintain the shape of cell

Cell membrane- present in both. Selective permeable

Nucleus- protein synthesis and remote control of the cell

Mitochondria- power house of the cell as it provides energy to cell

Chloroplast- present in plants. Known as kitchen of plant cell as the main site of preparation of food

Golgi- site of lipid synthesis and protein packaging

Endoplasmic reticulum- lipid synthesis, protein synthesis

Ribosomes - protein factory of the cell
