Eukaryotic+Prokaryotic Flashcards
Describe what are Eukaryotic Cells are and how how many cells are there?
What are prokaryotic cells?
Eukaryotic cells are membrane-bound organelles
12=2 plant cells + 10 Animals cells
Prokaryotic cells are not membrane bound organelles
What are the two plant cells present in Eukaryotic Cells?
Describe them and what is their function?
Chloroplast which is double membrane and is the site of photosynthesis.
Cell wall which is composed of cellulose.
Determine strength,shape and support of cell.
Control Turgid pressure by regulating water content.
What are the two Endoplasmic Reticulum present in Eukaryotic cells and what are their function and describe them?
Rough Endoplasmic Reticulum- Has Large number of ribosomes attached to it.
Function: Synthesise and ‘make changes’ to proteins
Smooth Endoplasmic Reticulum:
Function- Lipid Synthesise, toxin modification and Glycogenesis
[Glycogenesis- Glucose converted into Glycogen]
What is and describe the function of Nucleus?
Nucleus is double membrane.
Function: Control the cell
Contains chromosome and histones and one or more nucleoli for RNA Synthesis.
Describe everything about Mitochondria?
What is function of mitochondria?
What is the adaptation?
Mitochondria is double membrane.
Function: Site of Aerobic Respiration
Adaptation: Is folded called Cristae which gives it a large Surface Area so rate of Aerobic Respiration maximally increased.
what are the double membraned organelles?
Nucleus
Mitochondria
Chloroplast
What is the function of Ribosomes?
Synthesis proteins
What is the function of lysosomes?
Lysosomes get rid of unwanted cells/Organelles
Contain lysozymes which destroy pathogens
What is and the function of Cell-Surface Membrane?
Cell-Surface Membrane is a phospholipid Bilayer which control extra cellular substances entering and leaving
What is the function of the vacuole?
Vacuole function is to store water,nutrients and waste products.
What is the function of Golgi Body and Golgi Vesicle?
Golgi Body
Function: Modify Proteins and Role in ‘Packaging’ and secretion of protein.
Golgi Vesicle
Function: Gets packaged protein ready for export to other organelles
Contrasts Eukaryotic and Prokaryotic cells?
Eukaryotic cells are membrane-bound organelles and prokaryotic cells are not membrane-bound organelles.
Prokaryotic are smaller then Eukaryotes
(70s Ribosomes in Prokaryotic and 80s Eukaryotic)
Describe the structure of a prokaryotic cells.
DNA doesn’t contain histones
Have plasmids (extra Genetic Material)
Capsule surrounding the cells
Short Circular DNA
Flagella/Flagellum
Describe the Structure of Virus Structure
Has Reverse Transcriptase RNA to cDNA
Capsid (protects genetic material)
Nuclear envelope
Glycoprotein
Short circular DNA
