Growth in Animals and Plants
Fichas del conjunto (9)
- 1Define Growth How do you measure it?Growth is the increase of cells in number and in size.
Growth can be measured using length r mass - 2Name a few specialised animal cells. How does their structure relate to their function?1. Red blood cell
( High surface area for extra haemoglobin)
2. Fat Cells
(Stores large fat droplets until the body need energy)
3. Neurons
(Has long fibres that carry electrical impulses)
4.Muscle cells
(Contain contractile proteins that can shorten) - 3Why is differentiation important in the development of specialised cells?Without differentiation there wouldn't be any specialised cells as they are different in structure (which benefits them) to other cells.
- 4Know how to read and interpret percentile graphs.k
- 5What are the stages of plant growth?1. Cell division (mitosis)
2. Elongation
3. Differentiation - 6Describe Cell divisionAt the end of the shoot, a group of cells called meristems rapidly reproduce through mitosis.
- 7Describe ElongationThis is when the newly formed cells from the meristem increase in length.
- 8Describe DifferentiationThis is when the Elongated cells specialise into more complex cells to assist the plant another way.
(E.g. Xylem cells or Root hair cells ) - 9Name specialised plant cells and link their structure to their function.1. Xylem cells-
They have thick walls, pores, loss of wall to create a tube and no cytoplasm - This results in a tube resistant to high pressure that allows minerals and water to flow out through pores.
2.Palisade cells
They are found at the top of the tree and have a high surface area - This leads to high photosynthesis levels.
3.Root hair cells
They are long and have a high surface area - This results in high intake of the necessary water and mineral intake.
