Catalysts of Change
Enzymes are this type of biomolecule.
What are proteins?
Transport
What is the circulatory system?
Growth in response to light.
What is phototropism?
This plant structure can open and close to maintain water homeostasis.
What is the stomata?
Releasing and transporting hormones.
What are the circulatory and endocrine system?
This plant hormone helps plants conserve water and survive winter by inducing dormancy and closing stomata.
What is abscisic acid?
Gas exchange
What is the respiratory system?
Growth in response to touch.
What is thigmotropism?
This smelly response helps animals maintain body temperature when the temperature rises.
What is sweating?
This system works with the circulatory system to deliver oxygen to tissues and remove carbon dioxide through processes like gas exchange in the lungs.
What is the respiratory system?
Chemical messages
Hormones
What is the endocrine system?
These structures help increase the surface area for nutrient and water absorption.
What are root hairs?
This organ works to detect stimuli and coordinate responses to help animals maintain homeostasis.
What is the brain?
The immune system depends on this system to transport white blood cells throughout the body to fight infections.
What is the circulatory system?
This enzyme is found in the stomach and is the most efficient in environments with a low pH
What is Pepsin
Pathogens
These two types of vascular tissue work together to transport water, nutrients, and sugars throughout a plant, with one carrying water up from the roots and the other distributing sugars from the leaves.
What are xylem and phloem?
This type of regulatory mechanism helps maintain balance in the body by counteracting a change, such as the way your body regulates temperature or blood sugar levels.
What is a negative feedback loop?
These two systems work together to regulate metabolism by controlling the breakdown of food and the release of hormones that manage energy use and storage.
What are the digestive and endocrine systems?
This animal system is responsible for releasing hormones from glands.
What is the endocrine system?
Barrier
What is the integumentary system?
This process helps plants spread their offspring to new areas, reducing competition and increasing the chances of survival by allowing them to grow in different environments.
What is seed dispersal?
Plants are able to reproduce through self-pollination by transferring a grain of pollen to this female structure.
What is the stigma?
These two systems work together to regulate blood sugar levels, with one releasing hormones like insulin and the other sending signals to initiate a response.
What are the nervous and endocrine systems?
