B1 Cell Biology Flashcards
(45 cards)
What type of cells are Animal and plant cells?
Eukaryotic
Why are animal and plant cells classed as ‘eukaryotic’?
They have genetic material (DNA) formed in chromosomes that is contained in the nucleus.
Do animal cells and plant cells both have a cell membrane?
Yes, they do!
What is the purpose of a cell membrane?
It controls the movement of substances in and out of a cell.
Do animal cells and plant cells both have a nucleus?
Yep, they do!
What is the purpose of a cell membrane?
It controls the movement of substances in and out of a cell.
What is the purpose of a nucleus?
It contains DNA.
What is the purpose of a cell membrane?
It controls the movement of substances in and out of a cell.
Do plant cells and animal cells both have mitochondria?
Absolutely, they both do!
What is the purpose of mitochondria?
It’s where energy is released through respiration.
Do plant cells and animal cells both have ribosomes?
Yep, both do!
What is the purpose of ribosomes?
The site of protein synthesis.
Do animal cells and plant cells both have cytoplasm?
Yes!
What’s the purpose of cytoplasm?
It’s a jelly-like substance where chemical reactions happen.
Do plant and animal cells both have permanent vacuoles?
Nope, only plant cells!
What is the purpose of permanent vacuoles?
They contain cell sap.
Do plant and animal cells both have chloroplasts?
No, only plant cells!
What’s the purpose of chloroplasts?
They contain chlorophyll to absorb light energy for photosynthesis.
Do animal and plant cells both have cell walls?
Nah, only plant cells.
What’s the purpose of cell walls?
They’re made of cellulose which strengthens the cell.
What type of cell are bacteria?
Prokaryotic!
What characteristics do bacteria have?
•single-celled
•no nucleus (have a single loop of DNA)
•have small rings of DNA called plasmids
•smaller than eukaryotic cells
Do bacteria have a cell membrane?
Yes!
Do bacteria have a cell wall?
Absolutely!
