All cells are the same size and shape
There are no single cell organisms
Some living parts of organisms are not made of cells
Plants are not made of cells
Cells of living organisms do not make molecules for their own growth and repair
Animal cells do not eliminate their own wastes
Bacteria do not extract energy from food
Bacteria do not make molecules for their own growth
Bacteria do not carry out essential life functions for themselves
Bacteria do not eliminate their own wastes
Bacteria do not need a way to eliminate waste materials to function
Bacteria do not need molecules from food to function
Plant cells do not eliminate their own wastes
Animals do not make molecules for their own growth
Bacteria do not need water to function
Cells do not need water to function
Cells are not organised into the body structures they are part of
Plant cells do not make molecules for their own growth
In the early development of an organism, cells that result from the cell division do not
grow before dividing again
Organisms grow by cell division, but the cells do not themselves increase in size or
mass
In the early development of an organism, cells grow in size but the number of cells
remains constant.
In the early development of an organism, the organism grows in size and mass without
cell division or cell growth
The leaves of plants cannot develop from a single fertilised cell
Red blood cells do not supply oxygen to cells of the digestive tract
The flowers of plants cannot develop from a single fertilised cell
The stems of plants cannot develop from a single fertilised cell
Red blood cells do not supply oxygen to nerve cells
Genes are traits or characteristics
New cells form when old cells die
Cells spend most of their time dividing
Diploid cells (2n) are formed as a result of meiosis
The number of chromosomes is halved after mitosis
The number of chromosomes remains the same after meiosis
Larger macromolecules, such as proteins and carbohydrates, are made of cells
Fruits have the potential to develop into new plants
All cells have cytoplasm, cell membrane, nucleus and cell sap
Interphase is the resting phase of mitosis
In mitosis, homologous chromosomes separate in the anaphase
Diploid (2n) cells are formed as a result of meiosis
A chromosome has always two chromatids during cell division
Spindle fibres are formed by centromere
The number of chromosomes is halved after mitosis
The meiosis of a cell with 2n = 4 chromosomes produces cells with a single
chromosome
The number of chromosomes remains the same after meiosis
The number of chromosomes is doubled after mitosis
Students confuse the movement of chromosomes and chromatids during mitosis and
meiosis.
Meiosis can take place in any human body cell
Meiosis results in zygote formation
Only the mammalian life cycle involves meiosis, mitosis and fertilisation.
