1. State two structures found in animal cell but not plant cell
2. Name the tissue in plants responsible for growth
3. State the importance of specimen preservation
4. Explain why a virus can be both classified as a living and non living thing
5. State the characteristics of viruses
Answers
1.The lysosomes are the animal cell's “garbage disposal”, while in plant cells the same function takes place in vacuoles.the centrosomes are only present in animal cell
2.Primary meristems are responsible for the primary growth (lengthening) of the plant. Secondary meristems make the plant grow in thickness (secondary growth) and are formed by tissues that thicken the stem: cambium and phellogen (cork cambium).
3.Proper preservation ensures a high quality specimen, which increases the quality of information the specimen contains, and increases the value of the maintenance of the specimen.
4.A virus is a microscopic particle that can infect the cells of a biological organism. ... They are similar to obligate intracellular parasites as they lack the means for self-reproduction outside a host cell, but unlike parasites, viruses are generally not considered to be true living organisms.
5.Nonliving characteristics include the fact that they are not cells, have no cytoplasm or cellular organelles, and carry out no metabolism on their own and therefore must replicate using the host cell's metabolic machinery. Viruses can infect animals, plants, and even other microorganisms.......
