Eukaryotic plant cells

Question 1

vacuoles function

Answer 1

maintains cell turgidity and has a key role in regulating the cells water conc. in changing environmental conditions

Question 2

vacuole structure

Answer 2

membrane = tonoplast which is selectively permeable + filled with cell sap

Question 3

chloroplast function

Answer 3

responsible for photosynthesis

Question 4

chloroplast structure

Answer 4

–>double membrane
–>internal network of membranes form flattened sacs called thylakoids
–> a stack of thylakoids = a granum - contains chlorophyll
–> granum are joined by lamella membranes
–> contain their own ribosomes and DNA

Question 5

cell wall function

Answer 5

helps maintain cell shape by providing structure and support

Question 6

cell wall structure

Answer 6

rigid, contains pectin and hemicellulose
