Specialized plant cells

Question 1

What is the structure and function of the palisade cell?

Answer 1

Structure – typical plant cell structure but with many chloroplasts

Function – photosynthesis

Question 2

What is the structure and function of the root hair cell?

Answer 2

Structure – long, narrow extension

Function – absorption of nutrients and water from soil

Question 3

What is the structure and function of the guard cell?

Answer 3

Structure – pair of kidney shaped cells, less flexible inner cell wall

Function – control stomatal opening ( water exits, CO2 enters)

Question 4

What is the structure and function of the xylem cell?

Answer 4

Structure – long, dead, hollow, rigid tube like a straw, lignified cell walls

Function – transport water in plant

Question 5

What is the structure and function of the phloem cell?

Answer 5

Structure – long sieve tubes, partially broken down end walls forming sieve plates

Function – transport sugar from leaves to other parts of plants

Question 6

What is division of labor?

Answer 6

it is the sharing of work that can be done at different levels of organization within an organism eg. in every cell each organelle has a specific role and they work together to function properly.
Division of labour prevents cells from being overworked and ensures tasks are done efficiently.
