Cell Division, Differentiation & Stem Cells
Question 1 of 7
Plants contain cells with the ability to differentiate into specialised cells.
Specialised cells in plants include palisade cells, guard cells, and root hair cells.
What is the name given to cells that can differentiate into several types of specialised cells?
What is the function of these cells in the growth of a plant?
Explain why root hair cells are considered specialised cells.
The shape of the root hair cell is an adaptation.
Explain how this adaptation helps the root hair cell to absorb water and mineral ions from the soil more effectively.
Mitosis is a process of cell division in eukaryotic cells.
During mitosis, a parent cell divides to produce two identical daughter cells.
Give two reasons why new cells need to be produced throughout an organism's life.
Which cells, found in the early stages of embryonic development, have the potential to differentiate into specialised cells?
Complete the diagram to depict the levels of organisation found within a multicellular organism.
Cell → → Organ → → Organism
Name the organ in the human body responsible for pumping blood around the body.
Mitosis is a fundamental process of cell division that occurs in eukaryotic organisms.
During mitosis, a single cell divides into two identical daughter cells.
The picture below shows a stage of mitosis.
Name structure X.
Describe what happens immediately before mitosis.
How many cells are produced from one fertilised egg, after three cell divisions by mitosis?
Following mitosis, which process causes the divided cells to become specialised?
A student is trying to map out the sequence of events that occur during mitosis.
Put the following statements about mitosis in the correct order by writing the numbers1 to 6 into the table.
Plant cells divide by mitosis.
Before mitosis can take place, the cell prepares for cell division by obtaining nutrients, synthesising molecules, and replicating its DNA.
Which two cell components are duplicated before plant cells start to divide?
Plant cells divide by mitosis so that the plant can grow.
Give one other reason plant cells divide by mitosis.
Describe the process of mitosis from when the parent cell's chromosomes become visible to the production of two identical daughter cells.
In the human body, stem cells can differentiate into many different types of cells, including:
- Muscle cells
- Neurones
- Red blood cells
- White blood cells
- Sperm cells
- Egg cells
Which of the cells above are referred to as gametes?
Gametes have adaptations to increase the chances of fertilisation and therefore successful reproduction of the organism.
Explain how the adaptations of the male and female gametes allow them to carry out their job.
Which of these statements about red blood cells are correct?
The image below shows a cell going through the different stages of the cell cycle.
Assign numbers from 1 to 6 to each figure to arrange them chronologically.
