BI110 Lecture Notes - Lecture 28: Body Shape, Red Blood Cell, Endoplasmic Reticulum
Document Summary
Bi110 lecture 28 (wednesday november 22nd) start of chapter 10. Cells, tissues and organs: structure and function are related, ex. function of proteins related to their structure, more than 200 cell types in human body shape and structure of cells differ, characteristics of cells, 1. Individual cell: may be single or part of an ensemble, tissue, organ, organ system, organism. Long, multinucleated muscle cells have a striped appearance and are specialized for cotraction. Tissues and organs: a tissue is a collection of cells that work together to perform a specific function, two or more tissues combine and function together to make up an organ. Intermediate filaments (not necessarily specific to animal cells like the textbook says: more permeant structures, variable composition (keratin, lamin, least studied of the 3 structures. In between microtubules and microfilaments in diameter: right fluorescent microscopy, green mitochondria.
