Topic 1 Flashcards
What are eukaryotic cells
The are complex
All animal and plant cells are eukaryot
What are prokaryotic cells
They are smaller and simpler
Bacteria is an example
What features does an animal cell have
- nucleus
- cytoplasm
- cell membrane
- mitochondria
- ribosomes
What features does a plant cell have
Has all the bits of an animal cell plus:
- cell wall
- permanent vacuole
Nucleus
Contains genetic material
-genetic material controls what the cell does
Cytoplasm
Where most chemical reactions happen
Cell membrane
Controls what goes in and out of cell
Mitochondria
Where most aerobic respiration happens
What is respiration
Respiration transfers energy that the cell needs to work
Ribosomes
These are where proteins are made in the cell
Cell wall
Made of cellulose
It supports the cell and strengthens it
A permanent vacuole
Contains cell sap
Chloroplasts
Where photosynthesis happens
Photosynthesis makes food for the plant
What structure does a prokaryotic cell have such as bacteria
- cell wall
- cell membrane
- cytoplasm
- a single loop of DNA
- plasmids
How to estimate the area of a sub-cellular structure
Area = l x w
