INTRO TO CELLS

BIO 111 chapters 1-3

What is cell theory

Every living organism is composed of one or more cells, All cells came from pre existing cells, The smallest unit of life is a single cell

What are ways we can see a cell

microscopes, light microscope, electron microscope

What are the advantages of an Electron Microscope

higher resolution, 100,000 real life, can see inside cell

What are the characteristics of prokaryotes

small simple cells, no nucleus, Domain: Archea and bacteria

What are the charecteristics of Eukaryotes

Large and complex , Nucleus and many parts, Domain: eukarya , Single and multicellular

What is surface area

Outside edge of cell, Separates inside from out, Exchange of materials

What is Volume

Everything inside of cell, “needy “ part of cell

define paramecium

a single-celled freshwater animal that has a characteristic slipper-like shape and is covered with cilia.

what happens when cell size increase

surface area to volume ratio decreased

Define Multicellular

makes cell specialization possible and enables individuals to function more efficiently through division of labor, different cell types with same dna

what are the important functions in cells

Cell structure, Cell movement , Immune defense, Cell transport, Cell communication ,Enzymes

What is the protein structure

Sequence of amino acids > shape of protein > function of protein

how meany different types of cells are there?

220

Define Somatic Cells

any cell of a living organism other than the reproductive cells

What is the flow of information

Information > builder > Producer

Define gene regulation

cells regulate flow of genetic information

What are the advantages of being multicellular

increased size, longer lifespan due to cell specialization, the ability to perform complex functions through cell differentiation
