OAU POST UTME PRACTICE: Biology Quiz 1

Meiosis occurs during gamete formation in sex-organs.
The correct option is A

Seedless plants include bryophyles, (mosses & liverwort), pteridophytes (e.g. fern plant), thallophyles (c.g. red, brown & green algac).
Gymnosperms bear seed which is naked and are only borne on special compartment called cones (e.g. conifers).
Fungi is not a plant; it belongs to a separate kingdom. Bacteria are not classified as a plant as they also belong to a separate kingdom (moncran).
The correct option is D

High altitude is associated with lower average temperature and a greater diurnal temperature, high temperature (including snow), increase wind speed, more intense radiation, lower atmospheric pressure all of which have influence on plants and animal life. Note that high altitude is associated with high precipitation and not lower precipitation.
The correct option is C

Flagellation menning the presence or absence of flagellum in an organism. And it is often found in animal rather than a plant. It is used for classification in animals especially lower animal and not used for classification in plants.
Fucoxanthin is merely a type of pigment not a means of classification or grouping of piants
The correct option is D

Generally, the quantity of rainfall in Nigeria and worldwide determines to a large extent the type of vegetation of each biome or habitat.
Where rainfall abundantly throughout the year, the vegetation is dense rainforest.
The correct option is D.

Ecosystem is a community of organism and their physical environment interacting as an ecology unit. It is the basic functional unit in nature.
The correct option is B.

The mitochondria are double-membrane envelopes. The region between the outer and inner membranes, which is filled with liquid, is known as the outer compartment. The inner membrane has numerous folds called cristae.
Cristae are the sites of ATP synthesis, and their folded structure greatly increases the surface area where ATP synthesis occurs.
Transport proteins, molecules called electron transport chains, and enzymes that synthesize ATP are among the molecules embedded in the cristae. The cristue enclose a liquid-filled region known as the inner compartment, or matrix, which contains a large number of enzymes that are used in the process of acrobic respiration for classification in animals especially lower animal and not used for classification in plants.

The correct option is D

Food chain is the pathway along which food energy is transferred from trophic level to trophic level, beginning with producers.
Grass → Grasshopper → Toad → Snake → Hawk
