B1 Cell Biology Flashcards
What type of cells are plants and animals?
Eukaryotes
What does the nucleus contain?
DNA
What is the function of mitochondria?
Provides energy and allows respiration
Where do chemical reactions take place in a cell?
Cytoplasm
What is the role of the cell membrane?
Allows substances in and out of the cell
What does the vacuole contain?
Cell sap
What is the function of the cell wall?
Strengthens and adds structure to the cell
What is the site of protein synthesis in a cell?
Ribosomes
What do chloroplasts contain that allows for photosynthesis?
Chlorophyll
What type of cells are bacterial cells?
Prokaryotic
What is the function of a flagellum?
Allows bacteria to move
What are plasmids?
Strands of DNA
How many kingdoms of life are there?
5
Name the 5 kingdoms of life.
- Protists
- Plants
- Animals
- Bacteria
- Fungi
What type of organisms are animals and plants?
Multicellular
What type of organisms are bacteria?
Unicellular
Which type of microscope is cheaper and easier to use?
Light microscopes
Which type of microscope has a higher resolution?
Electron microscopes
• DNA condenses into chromosomes + produces more sub cellular smactures
L> They line up in the centre of the cells
→ Cell fibres pull two ams of each chromosome to opposite poles (scles)
→ Cytokinesis ( cell membrane + cytoplasm split in half
The entire cell divides to form new ‘daughter ‘ cells
