Ch. 3The Basic Structure of a Cell[細胞的基本結構] Introduction- Cells are basic units of organisms [引言:細胞是生物的基本單位] - Cells are very small in size and can only be observed under microscope. [細胞很細,只能用顯微鏡觀察] - Two basic types of cells: plant cells & animal cells...
TISSUESEVOLUTIONARY theoriesCOGNITIONCONSCIOUSNESSMULTICELLULAR organismsCells evolved some 4 billion years ago, and since then the integrity of the structural and functional continuity of cellular life has been maintained via highly conserved and ancient processes of cell reproduction and division. The pl...
Our body consists of a hierarchical structure of substances in order to carry out the functions needed for survival. We typically observe the higher levels of organization in our body. Organs, such as the heart, lungs, brain, kidneys, and li...
Organoids are three-dimensional (3D) miniature structures cultured in vitro produced from either human pluripotent stem cells (hPSCs) or adult stem cells (AdSCs) derived from healthy individuals or patients that recapitulate the cellular heterogeneity, structure, and functions of human organs. The adv...
fat. It is found throughout the body and is characterized by large, empty-looking cells that contain a single lipid droplet. White adipose tissue helps to insulate the body, protect organs, and provide a source of energy when needed. It is also involved in hormone regulation and immune ...

Study of the microscopic structure of tissues. Ectoderm Embryonic cell layer that differentiates into epithelial tissue of ectodermal origin. Mesoderm Embryonic cell layer that differentiates into connective tissue and muscle. Endoderm Embryonic cell layer that differentiates into epithelial tissue of endoderm...
Tissue is made up of cells that are like each other and do the same job. A group of cells with the same function make up tissue An organ is a structure made up of two or more tissues working together. A group of organs that work together form an organ system which is the highest ...
In a creature high on the evolutionary “tree of life”, one important feature is that each cell type has a physiological total number. Another trait is that in most organs and tissues, cells come and go by replication and death whereas, in some other cell types such as neurons and cardia...
These latter cells may be either scattered throughout the tissues or localized together in hemopoietidphagocytic organs. In addition to these cell-mediated defenses, there are a number of chemical and mechanical barriers to parasite invasion. The chapter also explains the structure and classification...
