The function of a sperm cell (repraduction)
The function of a sperm is basically to get male dna to the female dna
1 of 23
The function of a nerve cell (Rapid signalling)
The fuction of a nerve cell is to carry electrical signals from one part of the body to another
2 of 23
The function of a muscle cell ( contraction )
The function of a muscle cell is to contract quickly
3 of 23
what are root hair cell
root hair cells are cells on the surface of plant roots, which grow into long "hairs" that stick out into the soil
4 of 23
How are root hair cell specialised at absorbing water and minerals)
big surface area for absorbing water and minerals ions from the soil as well as long hair extension to increase the surface area for absorption.
5 of 23
what do both xylem cell and xylem tubes do
transport substances such as food and water around plants
6 of 23
how are sperm cell specialised
it has long tail and a streamlined head to help is swim to the egg/ a lot of mitochondria in the cell to prmm
7 of 23
how are muscle cell specialised
these cells are long (so that they have space to contract) and contains lots of mitochondria to generate the energy needed for contraction
8 of 23
how are nerve cell specialised
these cell are long (to cover more distance) and have branched connections at their ends to connect to other nerve cells and form a network throughout the body
9 of 23
The function of a xylem cell
transport water and minerals ions from roots to the leaves
10 of 23
stem cell
A stem cell is an undifferentiated cell that is capable of becoming other cell types
11 of 23
how are phloem speciaised
xylem cells are hollow in the centre and phloem cells have very few subcelluar structures so that stuff can flow through them
12 of 23
The function of a phloem cell
transport the products of photosynthesis from the leaves to the rest of the plant
13 of 23
what is differentiation
differentiation is the process by which a cell changes to become specialised for its job
14 of 23
what happens when a cell differentiates
it produces certain sub cellular structures to become a specialised cell that is adapted for its function
15 of 23
What structures do all cells have inside them?
sub-cellular structures
16 of 23
undifferentiated
called stem cells can divide to produce lots more undifferentiated cells. They can differentiate into different type of cell, depending on what instructions they;re given
17 of 23
where are stem cells found
in early human embroys
18 of 23
zygote
fertilized egg
19 of 23
where can u find adult stem cell
in certain places like bone marrow
20 of 23
what can stem cell be produced to do
to produce clones( genetically identical cell) and made to differentiate into specialist cells to use in medicine or research
21 of 23
why has it change to light to electron microscope
electron microscope have a higher magnification and a higher resoulution than light microscope
22 of 23
risk of light microscope(3)
Care must be taken when looking down the microscope if the illumination is too bright(1)/. Care when using microscope stains(!)/. Care when handling coverslips, microscope slides and mounted needles.
