BIOS 1404 Test 1

• indeterminate growth

–Answer When something grows throughout its life.

• two

–Answer Plants have major systems that they need for photosynthesis.

• root system

–Answer anchors the plant and takes in water and nutrients from the soil

• shoot system

–Answer this system harvests light and carbon dioxide from the atmos- phere to produce sugars

• Vascular tissue

–Answer structure where water and nutrients are transported to and from the roots to the shoots

• taproot

–Answer primary root found in some plants that grows longer and thicker than other roots

• lateral roots

–Answer The roots that grow out of the sides of a taproot.

• shoots system

–Answer a repeating series of nodes, internodes, leaves, and apical and axillary buds;

• phenotypic plasticity

–Answer when plants form are changeable, depending on environ- mental conditions 1 / 2

SUBSCRIBE

• nodes

–Answer a stem where leaves are attached

• internodes

–Answer segments between nodes. What is B?

• photosynthesis

–Answer A process used by plants and other autotrophs to capture light and energy and use it to power chemical reactions that convert carbon dioxide and water into oxygen and energy-rich carbohydrates, such as sugars and starches.

• light reaction

–Answer Part of photosynthesis that involves light. ATP and NADPH are produced. Takes place on the thylakoid membrane.

• calvin cycle

–Answer reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugars

• C4 photosynthesis

–Answer process that first converts CO2 into a 4-carbon molcule in the mesophyll cells, converts that product to malate and then shuttles it to the bundle sheath cells, where the malate releases CO2 and rubisco picks it up as if all were normal

• CAM plants

–Answer plants close their stomata during the day, collect CO2 at night, and store the CO2 in the form of acids until it is needed for photosynthesis, which can occur with stomata closed

• apical meristems

–Answer Embryonic plant tissue in the tips of roots and in the buds of shoots that supplies cells for the plant to grow in length.
