Roots respond byGrowing

Stems and leavesRespond by growingUpward

Geotropism is the growth response of a plant in response to gravity. Roots exhibit positive geotropism while stems and leaves exhibit negative geotropism.

Phototropism is the growth response of a plant in response to light direction. Different parts of a plant exhibit different reactions to light. Stems exhibit positive phototropism while most roots exhibit negative

phototropism.

Plant has lost Turgor Pressure

How does the plant regain turgor pressure?

Transpiration

Process of water evaporating from leaves through the stomata. This allows the leaf to take in carbon dioxide and eliminate oxygen

Botany

Botany is the study of plants.

How does the body respond to bacteriaand viruses in our body?

What is cellular respiration?

Cells of an organism use food nutrientsand oxygen to produce energy (ATP) thatCan be used by the organism to function

What is the waste products that is alsoProduce with the energy ATP?

How does the body maintain homeostasiswhen you exercise?

How does the body maintain homeostasiswhen you exercise?

Nervous system detects body temperatureIncrease and sends a message to sweat glandTo release sweat to cool the body

Nervous system detects high levels of CO2

in the blood and sends a message to therespiratory system to increase breathing and tothe circulatory system to increase heart rate to remove CO2 from the body and deliver moreoxygen to the body cells

How does the body maintain homeostasis ofBody temperature?
