Cell Structure Flashcards
What are the two types of differing cell structure
- Eukaryotic cells
* Prokaryotic cells
What makes an eukaryotes cell different
- Found in multicellular organisms
- membrane bound nucleus
- membrane bound components
What are the organelles found in eukaryotic cells
- Nucleus
- Nucleolus
- Mitochondria
- Vesicles
- Lysosomes
- cytoskeleton
- centrioles
- flagella and cilia
- SER
- RER
- ribosomes
- gioligi apparatus
What is the function of the nucleus
Contains DNA that has the blueprint for proteins
Nucleolus function
Area within the nucleus that is responsible for creating ribosomes
Mitochondria function
Site for final stages of reputation where energy is produced.
Has a double membrane the folded part is the cristae while the other is the matrix
Vesicles function
Single membrane sacs which aid in the transport and store of materials
Lysosomes
Specialised vesicles that contain hydrologic enzymes to break down waste products
Cytoskeleton
fibre that hold the shape of the cell, keeps organelles in place and controls movement within a cell.
Cytoskeleton can be further broken down into 3 components name these
•micro filaments
Made from actin involved in cell contraction and cytokinesis
•microtubules
Determines shape of the cell and acts as a road for transport
•intermediate fibres
Fibres that give mechanical strength
Centrioles function
•part of the cytoskeleton found in animals made up of microtubles, two centrioles working together are called a centresome
Flagella and cilia function
•flagella
Detecting chemical changes and involved in cell movement
•cilia
Mobile cilia will help move external objects
Stationary cilia is acts as a sensory organ
SER (smooth endoplasmic reticulum)
Responsible for the lipid and carbohydrates synthesis and also storage
RER (rough endoplasmic reticulum)
has ribosomes bound to it it is responsible for the synthesis and transport of proteins
Ribosomes function
site of protein synthesis
