A and  D i think

Oxygen is ONLY released and others are taken in.

Gas exchange during respiration occurs primarily through diffusion. Diffusion is a process in which transport is driven by a concentration gradient. Gas molecules move from a region of high concentration to a region of low concentration.

What are guard cells and their function?

Guard cells are another type of plant single-cell model to study early signal transduction and stress tolerance mechanisms in plants. Guard cells are surrounded by stomatal pores and are located in leaf epidermis. Guard cells control influx and efflux of CO2 and water from leaves, respectively.

What is the role of guard cells in a plant's leaves?

Guard cells are located in the leaf epidermis and pairs of guard cells surround and form stomatal pores, which regulate CO2 influx from the atmosphere into the leaves for photosynthetic carbon fixation. Stomatal guard cells also regulate water loss of plants via transpiration to the atmosphere.
