10 Questions
______ structure and function are studied in Biology.
Cell
______ Cells are cells with specific functions.
Specialised
______ is the movement of molecules from high concentration to low concentration.
Diffusion
A process like ______ helps maintain water balance in cells.
Osmosis
The ______ carries genetic information in cells.
DNA
Explain the similarities and differences between animal and plant cells in terms of structure and function.
Similarities: both have cell membrane, cytoplasm, and nucleus. Differences: plant cells have cell wall, chloroplasts, and large central vacuole.
Describe the structure and function of a neuron, highlighting its specialized features.
Neurons have dendrites, cell body, and axon. They transmit electrical impulses in one direction.
Explain how diffusion plays a role in gas exchange in the alveoli of the lungs.
Oxygen diffuses from the alveoli into the blood, while carbon dioxide diffuses from the blood into the alveoli.
Discuss the significance of osmosis in maintaining turgidity in plant cells.
Osmosis helps plant cells maintain their shape and rigidity by regulating water uptake and pressure.
Explain the structure of DNA and how it carries genetic information in cells.
DNA is a double helix made of nucleotides. It carries genetic information through sequences of nucleotide bases.
