Cell structure Flashcards
Are animal cells eukaryotic or prokaryotic cells?
Animal cells are eukaryotic cells
Are plant cells prokaryotic or eukaryotic cells?
Plant cells are eukaryotic cells
Are bacterial cells eukaryotic or prokaryotic cells?
Bacterial cells are prokaryotic cells
Are prokaryotic cells much bigger or much smaller than eukaryotic cells?
Prokaryotic cells are much smaller than eukaryotic cells
Give five sub cellular structures that are found in both animal and plant cells
Nucleus
Cytoplasm
Cell membrane
Ribosomes
Mitochondria
Give three sub cellular structures that found in plants cells but not animal cells
Cell wall
Chloroplasts
Permanent vacuole
Cell membrane
Controls what goes in and out of cell
Nucleus
Contains the genetic material and controls cellular activity
Cytoplasm
A jelly like substance where most of the chemical reactions take place
Mitochondria
Provides energy for the cell from respiration and aerobic respiration takes place
Ribosomes
Site of protein synthesis
Chloroplasts
Site of photosynthesis
Cell wall
Provides strength and structure. Made of cellulose
Plasmids
Rings of DNA which contains genes for antibiotic resistence
Slime Capsule
Used for protection against immune system
Flagella
Enables kovement
Why aren’t there chloroplasts and mitochondria in a bacterial cell?
This is because they are too large for the cell
Cell differentiation
Takes place early in embryo’s development and given the particular job
Sperm cell
Tail- enables movement
Mitochondria- energy for enabling movement
Light microscope
Light
Cheap
Low resolution
Low magnification
Electron microscope
Electron beam
Expensive
High resolution
High magnification
Cells
The basic unit that makes an organisation
Tissue
A group of similar cells that work together to perform a particular function
Organ
A group of similar tissues that work together to perform a particular function
Organ system
A group of organs that work together to perform a particular function
