Answers
A1. The plastid is a major double membrane organelle found, among other, in the cells of plants and algae. Plastids are the site of manufacture and storage of important chemical compounds used by the cells. ... LEUCOPLAST are non pigmented organelles. They have no colour at all
A2.The Golgi body is an organelle found in most eukaryotic cells. ... The Golgi body has a number of functions, including sorting and processing proteins. Proteins are synthesized in the rough endoplasmic reticulum, then they travel to the Golgi body. While in the Golgi body, they are processed and sent throughout the cell.
A3.Nucleoid is an region of undefined nuclear region in cytoplasm of Prokaryotic cells , which contains chromatin structure which has the hereditary material of the cell.
A4. A difference between plant cells and animal cells is that most animal cells are round whereas most plant cells are rectangular. Plant cells have a rigid cell wall that surrounds the cell membrane. Animal cells do not have a cell wall.
A6.LYSOSOMES are called suicide bags of the cell because digest materials taken up from outside the cell. ... LYSOSOMES HAVE DIGESTIVE ENZYMES. WHEN LYSOSOMES BURSTS DIGESTIVE ENZYMES DIGEST ITS OWN CELL.SO THEY ARE CALLED SUICIDAL BAGS OF THE CELL
A7.The Function of Chromosomes. Chromosomes are the thread-like structure found in the nuclei of both animal and plant cells. They are made of protein and one molecule of deoxyribonucleic acid (DNA). ... Chromosomes are important to this process to ensure the DNA is accurately replicated.
A8.The smallest cell in the human body is the sperm cell. These cells are small in volume. Head of the sperm cell measures about 4 micrometres in length, just a little bit smaller than a red blood cell (RBCs). The largest cell in the human body is Egg cells (ovum).
A9.The largest cell in the human body is female ovum.
A10.The plant cells are more rigid compared to animal cells as they have cell wall. It provides rigidity as well as protection from outer environment. ... Similarly, when excess water enters cell, the plant cell swells but it do not burst due to presence of wall pressure
A11.An example of osmosis is slowly learning how to sew after sitting next to an experience seamstress. Osmosis is defined as the distribution of liquid with a low concentration flowing through a membrane into an area with a higher concentration resulting in the concentrations being equal on both sides.
