C3.1 Integration of body systems HL

Question 1

Function of the Enteric Nervous System

Answer 1

Regulates gastrointestinal movement and digestion processes

Question 2

Enteric Nervous System vs CNS

Answer 2

Enteric: Autonomous control of gut. CNS: Controls swallowing and egestion

Question 3

Neuronal Control of Digestion

Answer 3

Enteric neurons manage peristalsis and secretion in digestion

Question 4

Role in Gastrointestinal Motility

Answer 4

Coordinates contraction of GI muscles for food movement

Question 5

Autonomous Nature of the Enteric System

Answer 5

Operates independently of the central nervous system

Question 6

Phototropism

Answer 6

Growth of plant parts towards or away from light

Question 7

Geotropism

Answer 7

Plant growth in response to gravity

Question 8

Tropic Movements

Answer 8

Directional growth movements responding to environmental stimuli

Question 9

Role of Auxins in Phototropism

Answer 9

Hormones promoting growth towards light

Question 10

Impact of Gravity on Plant Growth

Answer 10

Influences direction of roots (positive geotropism) and stems (negative geotropism)

Question 11

Auxins

Answer 11

Promote cell elongation, involved in phototropism and geotropism

Question 12

Gibberellins

Answer 12

Stimulate stem elongation, seed germination, and flowering

Question 13

Cytokinins

Answer 13

Promote cell division and growth, delay aging in leaves

Question 14

Abscisic Acid (ABA)

Answer 14

Regulates stress responses, seed dormancy, and stomatal closure

Question 15

Ethylene

Answer 15

Controls fruit ripening, leaf abscission, and flower wilting
