(44 cards)
Somatic
Body cells
Gametes
Sex cells
Are diploid cells that divide to give rise to differentiated cells and replicate themselves in a process called “renewal”
Stem Cells
Cells are composed of macromolecules such as
Carbohydrates
Lipids
Proteins
Nucleic Acids
Carbohydrates
Sugars and Starches
Lipids
Fat and oils
Proteins
Enzyme reactions to sustain life
Nucleic Acids
DNA and RNA
Control center of the cell
Nucleus
Site of protein synthesis and folding; lipid synthesis
Endoplasmic Reticulum
Has ribosomes, protein synthesis
Rough Endoplasmic Reticulum (rER)
Lipid synthesis
Has no ribosomes attached
Soft Endoplasmic Reticulum (sER)
Site where sugars are made and linked into starches or joined to lipids or proteins; proteins finish folding; secretions stored
Golgi Apparatus
Degrades debris; recycles cell contents
Lysosome
Releases energy from nutrients, participate in cell death
Mitochondrion
Breaks down and detoxifies various molecules
Peroxisome
Scaffoid and catalyst for protein synthesis
Ribosome
Stores and transports substances
Vesicle
Bilayer molecules called phospholipids which forms the structural backbone
Plasma Membrane
Plasma Membrane layers
Hydropholic layer (outer) Hydrophobic layer (inner)
Meshwork of protein rods and tubules that serves as the cell’s architecture, positioning organelles overall providing 3D shape
Cytoskeleton
Cytoskeleton has 3 major types of elements, what are these?
Microtubules, microfilaments and intermediate filaments
All cells have 3 things in common, what are these?
Cell membrane
Cytoplasm
Dna
do eukaryotic cells have nucleus
Yes
