This page delves into the types of diabetes and their causes, as well as the structure and function of the circulatory system. It emphasizes the importance of efficient transport and exchange in organisms.
Key points:
Definition: Diabetes is a condition characterized by high blood glucose levels due to issues with insulin production or response.
Highlight: The heart is a muscular pump with four chambers that circulates blood throughout the body.
Photosynthesis is a crucial biological process that occurs in chloroplasts, providing energy for plants and animals while producing oxygen. How photosynthesis increases plant biomass is explained through its endothermic nature and glucose production.
Key points:
Definition: Photosynthesis is an endothermic reaction where light energy is used to convert carbon dioxide and water into glucose and oxygen.
Highlight: Leaves have specific adaptations to maximize photosynthesis, including broad surfaces, palisade cells packed with chloroplasts, and stomata for gas exchange.
This section covers cellular respiration and introduces key concepts in ecosystem biology. It explains how energy is released from glucose and defines important ecological terms.
Key concepts:
Vocabulary: An ecosystem includes all the organisms in a given area and their interactions with the physical environment.
Example: Quadrats are used to sample and estimate population sizes in ecology studies.
This section covers the movement of water and nutrients in plants through transpiration and translocation. It also introduces hormones and their role in the body, particularly focusing on the control of blood glucose and its relation to insulin.
Key concepts:
Vocabulary: Transpiration is the movement of water from roots through the xylem and out of the stomata.
Example: The menstrual cycle is regulated by hormones, demonstrating the importance of endocrine system in reproductive processes.
