B1: Cells Structure and Support Flashcards
What is in a animal cell?
- Cytoplasm
- Ribosomes
- Cell membrane
- Nucleus
- Mitochondria
What is in a plant cell?
- Chloroplasts
- Ribosomes
- Cell membrane
- Nucleus
- Mitochondria
- Permant Vacule
- Cell wall
How is a root hair cell specialised?
- They uptake of water and nutreients by having a large surface area
- They contain mitochondria to do active transport so they can form more nutrients
How is a sperm cell specialised?
- Specialises to help function the egg and the tail
- Lots of mitochondria to stay energised
- The nucleus helps fertilise the egg
How is a nerve cell specialised?
- Lots of dentries to make conections to other nerve cells
- Exop carries the nerve impulse
- lots of mitochondria to transfer chemicals
What is the function of a cell membrane?
It allows the passage of substances in and out of the cell - found in plant and animal cells
What is the function of a cytoplasm?
Jelly-like substance, where chemical reactions take place
- found in plant and animal cells
What is the function of a nuclues?
Contains genetic material and controls the cells activity
- found in plant and animal cells
What is the function of mitochondria?
Where aeorobic resperation happens and provides energy for the cell
- found in plant and animal cells
What is the function of a permant vacule?
Contains a liquid called cell sap, which keeps the cell firm
- found in plant cell ONLY
What is the function of a cell wall?
Gives the cell structure and support, keeps cell rigid
- found in plant cell ONLY
What is the function of a chloroplast?
Contains chlorophyll (a green pigment used to carry out photosynthesis)
- found in plant cell ONLY
What are features of Prokaryotic Cells?
- contians small rings of DNA
- bacteria cells
- smaller
- fagella
- cells wall
What are some features of Eukaryotic Cells?
- aminal and plant cells
- no slime capsules
- bigger
- vacules
- fungi, humans, plants
- chromosones
What do Prokaryoic cells and eukaryotic cells similarities?
- cell membrane
- cytoplasm
- nuclues
- genetic material
- cell wall (plant cell)
