Plant Biology Lecture Notes

These flashcards cover key concepts from plant biology, including meristems, guard cells, photosynthesis, and the structural differences between plant and non-plant cells.

Meristems are regions within plants that are actively undergoing relatively high rates of _ ____ where primary growth is initiated.

cell division

Guard cells are responsible for controlling the intake of molecules of ___, which are required for the __ reactions of photosynthesis to occur.

carbon dioxide; photosynthetic

The activities of these cells also affect evaporation of water from the plant through a process known as

transpiration

In what structures within plant cells do photosynthesis reactions occur?

chloroplasts

What are the three basic inputs required by photosynthesis reactions?

water, carbon dioxide, sunlight

What are the two ultimate products of photosynthesis reactions?

glucose and oxygen

What three structures would occur within the cells of plants that would not occur in the cells of non-plant organisms?

chloroplasts, cell walls, vacuoles

What four organs would you examine in order to determine whether a particular plant species is a monocot or eudicot?

leaves, stems, roots, flowers
