I.) What is the cell membrane? A. AKA: Plasma membrane B. The boundary between the cell and the environment C. Does every cell have a cell membrane? 1. Yes, Each and every cell has a cell membrane. Cell membranes help maintain homeostasis, what is that? 1. Cells breathing 2 ...
Learning objectives At the end of lecture student should be able to • Describe the structure of cell membrane • Explain molecular basis of cell membrane • Name different types of membrane protein • Correlate functions with structure of membrane Membranes (highly fluid & Dynamic structure) Plasma membranes form ...
Objectives At the end of this session, the students should be able to: • Describe the fluid mosaic model of membrane structure and function. • Define permeability and list factors influencing permeability. • Identify and describe carried-mediated transport processes: Primary active transport, secondary active transport, facilitates diffusion. Previously.. • Fluid ...
S7L2. Students will describe the structure and function of cells, tissues, organs, and organ systems. A. Explain that cells take in nutrients in order to grow and divide and to make needed materials. B. Relate cell structures (cell membrane, nucleus, cytoplasm, chloroplasts, mitochondria) to basic cell functions. C. Explain that ...

There are 2 types of cells 1. Prokaryotes 2. Eukaryotes Prokaryotes • Do NOT have a membrane surrounding genetic material, therefore, can make proteins simultaneously when reading genetic code. • Lack some structures found in Eukaryotic cells Eukaryotes • Have a membrane surrounding their DNA, forming a NUCLEUS • Contain ...
What is a model? • Models are conceptual representations used to explain and predict phenomena. • Models can be quite useful when the subject under study (the membrane in this case) cannot be observed directly. SCIENTIFIC MODELS are HYPOTHESIS THAT A. Explain observations B. Predict future observations C. Are realistic ...
Robert Hook • 1665 - Hook used a primitive microscope to view cork. What he saw (cell walls) he described as “cells” because they looked like rooms in a monastery. The Cell Theory (1835-1855) Schleiden, Schwann, and Virchow 1. All living things are composed of cells. 2. Cells are ...
How big is a cell? • http://www.cellsalive.com/howbig.htm The Cell Theory The Cell Theory 1. All organisms are made of cells. 2. The cell is the basic unit of life in all living things. 3. All cells come from existing cells. THIS IS IMPORTANT BECAUSE IT SHOWS THAT ...
