What is the function of the xylem, sporangium, cerebrum, and sensory neurons in plants and animals?

Here are the solutions for the questions from the image:

15. A structure which carries water from the roots to the leaves:
The xylem is the plant tissue responsible for transporting water and dissolved minerals from the roots upwards to the rest of the plant, including the leaves.

The correct option is C. Xylem.

16. Below is the structure of a mould fungus: The structure numbered 4 functions in?
Structure 4 in the diagram of the mould fungus represents the sporangium. The primary function of the sporangium is the enclosure of spores until they are mature and ready for dispersal.

The correct option is Enclosure of spores.

17. Which part of the mammalian brain is responsible for voluntary activities of the body?
The cerebrum is the largest part of the brain and is responsible for higher-level functions such as voluntary movements, thought, memory, and sensory processing.

The correct option is B. Cerebrum.

18. The sensory neurons plays a role in conducting impulses from the:
Sensory neurons (afferent neurons) transmit nerve impulses from sensory receptors (which detect stimuli) to the central nervous system (brain and spinal cord) for interpretation.

The correct option is A. Receptor to the central nervous system.

19. The diagram below is a cross-section of a hibiscus flower Which part is responsible to attract insects for pollination?
The petals of a flower are typically brightly colored, often scented, and shaped to attract pollinators like insects, guiding them towards the reproductive organs.

The correct option is A. Petal.

20. Below is a diagram of a bacterial cell Which structure is labelled 1?
Structure 1 in the diagram of the bacterial cell points to the long, whip-like appendage that extends from the cell body and is used for movement. This structure is a flagellum.

The correct option is A. Flagellum.
