Structure and Function of tissues, organs and systems Flashcards
What are four tissues in a leaf and their function
Epidermis: waxy protective layer to protect against drought, UV and pathogen
Mesophyll: contributes in gas exchange and transpiration, is found in between upper and lower epidermis
Phloem: carries glucose from the leaves to the rest of the plant
Xylem: carries water from the roots to the leaves of the plant as needed for photosynthesis
What are four tissues and their functions in a mammalian system
epithelial tissue: provides a lining to protect other organs and tissues
Connective tissue: connects and supports different organs and tissues in the body
Muscle tissue: thin elongated fibres that apply forces to the body to create movement
Nervous tissue: monitors and regulates body function through electric impulses
What are the eleven major organ systems and their roles
Integumentary: protects from water loss and outside environment
Endocrine: hormone production and regulation
Respiratory: gas exchange
Excretory: removes waste material
Lymphatic: aids in immune function
Digestive: chemical and mechanical breakdown of food
Muscular: facilitates movement
Reproductive: enables reproduction
Circulatory: transport gases, nutrients and waste
Skeletal: supports body and protects vital organs
Nervous: coordinates involuntary and voluntary responses
Justify the hierarchical structure of organisation (organelles, cells, tissues, organs, systems, organism)
Provides chronology to size, function and complexity –> easier to understand roles

How are vascular bundles in plants arranged
consist of two primary specialised tissues: xylem on the inside to transport water, phloem outside that transports glucose around plant
