Tissues, cells + organs SPEC Flashcards
What features that plant + algal cells have that animal + humans cells don’t?
Cell wall, cellulose, strenthens cell
Chloroplasts, absorb light energy, make food
Permanent vacoule - cell sap
Describe bacterial cell
cell membrane
cell wall
cytoplasm
genes not in distinct nucleus
Describe yeast cell
single-celled organism nucleus cell membrane cell wall cytoplasm
why may cells be specialised?
to carry out a particular function
Give some examples of specialised cells?
plant cells, many chloroplasts, photosynthesising
mesophyll cells leaf
root hair cells
increased surface area –> efficient absorbtion
mineral ions + water
sperm + muscle cells, lots of mitochondria
release energy for movements
gland cells, lots of ribosomes
make lots of protein
produce enzymes
