cells + control // growth in plants

Question 1

Describe the stages of growth in plants

Answer 1

cell division/mitosis, elongation, differentiation

Question 2

Give examples of specialised plant cells

Answer 2

• Xylem Cell
• Phloem Cell
• Root Hair Cell

Question 3

Describe how the root hair cell is adapted to its function

Answer 3

it has a larger surface area which allows it to absorb more minerals and water from the soil

Question 4

Describe how the xylem cell is adapted to its function

Answer 4

the cells that make up the xylem are adapted to their function: They lose their end walls so the xylem forms a continuous, hollow tube. They become strengthened by a substance called lignin and can provide minerals + support to the plant easier.

Question 5

Describe how the phloem cell is adapted to its function

Answer 5

the cells that make up the phloem are adapted to their function: … Each sieve tube has a perforated end so its cytoplasm connects one cell to the next. Companion cells - transport of substances in the phloem requires energy. One or more companion cells attached to each sieve tube provide this energy.

Question 6

Explain why cell differentiation is important in the development of specialised cells in plants

Answer 6

differentiated cells are important in a multicellular organism because they are able to perform a specialised function in the body.
