| 1. |
A plant which grows on another plant without apparent harm to the host plant is called A. a parasite B. an epiphyte C. a saprophyte D. a predator E. a hermaphrodite Detailed SolutionEpiphytes, which differ from parasites in the sense that epiphytes grow on other plants for physical support and do not necessarily negatively affect the host. Hence, epiphytes show no apparent harm to the host plant. |
|
| 2. |
Given the equation: A. proteinsynthesis B. respiration C. photosynthesis D. transpiration E. translocation Detailed SolutionThe given equation is that of photosynthesis which is the use of sunlight and chlorophyll by green plants in order to yield their food. The equation yields sugar and oxygen. |
|
| 3. |
Given the equation: A. sunlight B. chlorophyll C. carbon dioxide D. atmosphere E. water Detailed SolutionThe oxygen given of by plants is from WATER which is split during photolysis(splitting of water by sunlight). |
|
| 4. |
One of the function of xylem is A. strengthening the stem B. manufacturing food C. reducing loss of water D. conducting manufactured food E. storing unused sugar Detailed Solution. Xylem plays an essential 'supporting' role providing strength to tissues and organs, to maintain plant architecture and resistance to bending. |
|
| 5. |
People suffering from myopia A. can see near object clearly B. can see far away object clearly C. cannot see any object clearly D. are colour blind E. are able to see clearly in the dark Detailed SolutionMyopia is another name given to short- sightedness. Affected persons see close objects clearly but far objects are blurry and would take correction to get from a distance fixed on their retina. |
|
| 6. |
The cilia in paramecium are use for A. respirating B. locomotion C. protection D. regulating food intake E. excretion Detailed SolutionCilia have important functions in the life of Paramecium, such as locomotion through the surrounding water and ingestion of food into the cytostome. |
|
| 7. |
Euglena may be classified as a plant because it A. has chloroplast B. has a gullet C. lives in a pond D. possesses a flagellum E. has pellicle Detailed SolutionMost euglena have chloroplasts, which is a basic characteristics of plants. |
|
| 8. |
A trawler on a fishing trip caught a type of animal with hairs on its body. This animal could have been A. An amphibian B. a reptile C. a shark D. a mammal E. a seagull Detailed SolutionWe have aquatic mammals. These are mammals which depend on water either fully or partly. They have the qualities of mammals |
|
| 9. |
Which of these type of skeleton is most appropriate for a cockroach? A. Hydrostatic skeleton B. Exoskeleton C. Endoskeleton D. Cartilaginous skeleton E. Bony skeleton Detailed SolutionLike most other insects, cockroaches have an exoskeleton, meaning their skeleton is located on the outside of their bodies. |
|
| 10. |
When protein are broken down they provide A. oxygen B. carbonhydrate C. energy D. amino-acid E. carbon dioxide Detailed SolutionThe end-product of the breakdown of protein is amino-acids and other simple products. |
