Anatomy Lab 4 Flashcards
Eukaryotic Cell
-Plasma membrane
-Nucleus
-Organelles: Mitochondria
Ribosomes
Rough endoplasmic reticulum
Smooth endoplasmic reticulum
Golgi apparatus
Lysosomes
Centrosome
Plasma Membrane
-Separates cell from its environment
-controls passage of substances
-carbohydrates-recognition of neighbors
-phospholipid bilayer
Plasma Membrane is Selectively Permeable
-Pores
-Simple Diffusion
-Facilitated Diffusion
-Active Transport
Parts of a Nucleus
-Endoplasmic reticulum
-Nucleolus
-Chromatin
-Nucleoplasm
-Nuclear pore
-Nuclear envelope
What is the nuclear envelope (membrane) continuous with?
ER membrane
What does nuclear pore allow to escape into the cytoplasm?
mRNA
What does chromatin condense into at division?
chromosomes
What does the nucleolus produce?
-ribosomal subunits
-rRNA
Mitochondria
-Smooth outer membrane
-Highly folded inner membrane
-location of electron transport chain enzymes
-high proton concentration in-between outer and inner membrane
Where is there a high content of mitochondria?
in metabolically active cells
ER and Golgi Apparatus
-Smooth ER
-Rough ER
-Golgi apparatus (Body)
-Proteins move from rough ER to Golgi apparatus
Smooth ER
-synthesis of lipids and steroids
Rough ER
-Ribosomes
-protein synthesis
Golgi apparatus (BOdy)
-modification of some proteins
What comes from fertilisation?
-Somatic cells
-germ cells
