C. Economic importance of mosses?
16. a. What is seed plant?A plant which reproduce by seed.
b. Explain Birds.A warm-blooded egg-laying vertebrate animal distinguished by the possession of feathers, wings, a beak, and typically by being able to fly
c. Ecological and economic importance of fungi?Fungi play many roles in nature. One is that of a decomposer. Mold, mildew and mushrooms grow on dead organic matter and are able to obtain nutrients while breaking down the organic matter which helps to recycle their components back to the environment.
A. What is virus and which diseases can it cause.
b. Animal body is complex and has many systems, say 3 of them.Respiratory, Circulatory and Skeletal system
c. Say general properties of Kingdom Monera.Single celled, some are motile, some are autotrophs others obtain food from different organisms.
18.a. What is Zoology?Zoology is the scientific study of the characteristics and classification of animals. It is one of the branches of biology.
b. Explain amphibians.A cold-blooded vertebrate animal of a class that comprises the frogs, toads, newts, salamanders, and caecilians. They are distinguished by having an aquatic gill-breathing larval stage followed (typically) by a terrestrial lung-breathing adult stage.
c. Say general properties of Kingdom Protista.Protists are eukaryotic organisms that cannot be classified as a plant, animal, or fungus. They are mostly unicellular, but some, like algae, are multicellular. Kelp, or 'seaweed,' is a large multicellular protist that provides food, shelter, and oxygen for numerous underwater ecosystems. Even though kelp resembles a plant, it is not classified into Kingdom Plantae because it lacks the cellular complexity of plant cells.
19. a. Explain Fish (Pisces) and give examples. Most fish are cold-blooded, allowing their body temperatures to vary as ambient temperatures change, though some of the large active swimmers like white shark and tuna can hold a higher core temperature.
b. Explain Arthropods and give examples..It mean join legs their body is 3 part head, tharax, abdomen. The three main classes of arthropods are: insectscrustaceansand arachnids. Arthropods present three distinguishing features: they are metameric organisms (segmented body).
c. Classify bacteria according to its’ Nutrition.Autotrophic and Heterotrophic.
20.a. Explain Mammals..A warm-blooded vertebrate animal of a class that is distinguished by the possession of hair or fur, females that secrete milk for the nourishment of the young, and (typically) the birth of live youngMammals are the vertebrates within the class Mammalia.

b. Explain Birds. A warm-blooded egg-laying vertebrate animal distinguished by the possession of feathers, wings, a beak, and typically by being able to fly
c. What is cell? Say main 3 main parts of it.All living things are made up of cells, (2) Cells are the smallest units (or most basic building blocks) of life, and (3) All cells come from preexisting cells through the process of cell division. Cells were first observed by the natural philosopher Robert Hooke in 1665.
21. a. Give an example for open seed plant.Bulb, Tuber, Corn, Coconut.
b. Animal body is complex and has many systems, say 3 of them.Respiratory, Circulatory and Skeletal system
c. What is Homologous organ?Organs such as bat's wing, wings of birds, seal’s flipper, forelimb of a horse, and human arm have a common underlying anatomy that was present in their last common ancestors; therefore their forelimbs are homologous organs.
22. a. Say general properties of Kingdom fungi.Members of the kingdom Fungi are eukaryotes, meaning they have complex cells with a nucleus and organelles. Most are multicellular, with the exception of single-celled yeast. Structurally, fungi are made up of individual feathery filaments called hyphae.
b. Explain amphibians.A cold-blooded vertebrate animal of a class that comprises the frogs, toads, newts, salamanders, and caecilians. They are distinguished by having an aquatic gill-breathing larval stage followed (typically) by a terrestrial lung-breathing adult stage.
c. What is Basidomycota?A division of higher fungi comprising the basidiomycetes when they are considered a division.
23.a. Explain Mammals..A warm-blooded vertebrate animal of a class that is distinguished by the possession of hair or fur, females that secrete milk for the nourishment of the young, and (typically) the birth of live youngMammals are the vertebrates within the class Mammalia.
b. Explain Arthropods and give examples..It mean join legs their body is 3 part head, tharax, abdomen. The three main classes of arthropods are: insectscrustaceansand arachnids. Arthropods present three distinguishing features: they are metameric organisms (segmented body).
