3 parts of cell theory? Types of cells it applies to?
All life is made up of cells, all cells are made from pre-exhisiting cells, cells are the most basic form of life
Applies to all cells
-
contractile vacuole
- gets rid of excess water, found in some protists
- prevents bursting of cell and dilution
-
central vacuole
stores mostly water, only one, only found in plants
-
Funtion of vacuole
storage containers of various substances
-
Funtion of smooth er
synthesizes lipids, stores calcium, detoxifies enzymes
-
Funtion of rough er
makes more membrane, modifies proteins
-
Funtion of cell wall
rigid, tough layer, keeps cell from bursting, made of cellulose
-
Funtion of peroxisome
break down fatty acids, H2O2 (catalase), synthesis of myelin, produced by ER
-
Funtion of lysosome
digests food particles to release nutrients to cell, destroys damaged organelles, contains powerful digestive enzymes
-
Funtion of nucleus
encloses DNA, control center of the cell
-
Funtion of ribosomes
makes proteins using instructions from DNA
-
Funtion of golgi body
recieves vesicles for the ER and finishes, sorts, and ships proteins
-
Funtion of mitochondira
site of cellular respiration and creates energy for the cell (ATP)
-
Funtion/parts of cytoskeleton
- function: help with support/ internal structure and movement
- parts: microfilaments, intermediate filaments, microtubules
-
Funtion of chloroplast
make food through photosynthesis
-
Funtion of cytoplasm
hold structures in place within the cell: metabolic chemical reactions occur here
-
Funtion of cell membrane
regulates what enters and leaves the cell
-
Chromatin
uncoiled DNA, usually in this form
-
Chromosome
- coiled DNA, contains genes
- all humans contain 46 in each cell except red blood cells and gametes
-
Importance of large surface area in cell
Absorb nutrients, oxygen, water, etc. and dispose of waste
-
Protist
unicellular eukaryote
-
Ex: prokaryotes and eukaryotes
- pro: bacteria
- eu: plants, animals, fungi, protists
-
Prokaryotes vs. eukaryotes
- Pro: small, unicellular, simple, no membrane bound organelles, no nucleus, reproduce asexually
- Eu: Larger, mulit/unicellular, more complex, membrane bound organelles, nucleus
-
Parts in all cells?
Cell membrane, genetic information (DNA), ribosomes, cytoplasm
