Plant Cell And Animal Cell Biography

Animal cells usually have an irregular shape, and plant cells usually have a regular shape
Cells are made up of different parts. It is easier to explain what these parts are by using diagrams like the ones below.
Animal and plant cells both have a cell membrane, cytoplasm, and a nucleus. Plant cells also have chloroplasts, a vacuole and a cell wall.
Animal cells and plant cells both contain:
cell membrane, cytoplasm, nucleus
Plant cells also contain these parts, not found in animal cells:
chloroplasts, vacuole, cell wall
The table summarises the functions of these parts.
Part Function Found in
Cell membrane Controls what substances can get into and out of the cell. Plant and animal cells
Cytoplasm Jelly-like substance, where chemical reactions happen. In plant cells there's a thin lining, whereas in animal cells most of the cell is cytoplasm. Plant and animal cells
Nucleus
Controls what happens inside the cell. Carries genetic information.
In exams don't call the nucleus the 'brain' of the cell. That is not a good description and will not get you marks.
Plant and animal cells
Chloroplast Where photosynthesis happens – chloroplasts contain a green substance called chlorophyll. Plant cells only
Vacuole Contains a liquid called cell sap, which keeps the cell firm. Plant cells only
Cell wall Made of a tough substance called cellulose, which supports the cell. Plant cells only
Humans are multi-cellular animals. That means we are made of lots of cells, not just one cell. The cells in many multi-cellular animals and plants are specialised, so that they can share out the processes of life. They work together like a team to support the different processes in an organism.
Specialised cells
You should be able to work out special features of a cell from a drawing, if you are told what the cell can do. The tables below show examples of some specialised animal and plant cells, with their functions and special features.
Type of animal cell Function Special features
Red blood cells
Some red blood cells
To carry oxygen
Large surface area, for oxygen to pass through
Contains haemoglobin, which joins with oxygen
Nerve cells
Nerve cells
To carry nerve impulses to different parts of the body
Long
Connections at each end
Can carry electrical signals
Female reproductive cell (egg cell)
an egg cell
To join with male cell, and then to provide food for the new cell that's been formed
Large
Contains lots of cytoplasm
Male reproductive cell (sperm cell)
a sperm cell
To reach female cell, and join with it
Long tail for swimming
Head for getting into the female cell
Type of plant cell Function Special features
Root hair cell
Diagram of a root cell in a plant
To absorb water and minerals
Large surface area
Leaf cell
Diagram of a plant leaf cell
To absorb sunlight for photosynthesis
Large surface area
Lots of chloroplasts
