The cell as the basic unit of lifeCells are the basic units of organismsAll cells come from preexisting cells through cell division. Unicellular organisms are made of one cell onlyThe cells of multicellular organisms are specialized to perform different functionse.g. mesophyll cells for photosynthesis and root hair cells for water absorptionThere are many different kinds of cells, doing many different jobs in a plant or animal.
Most living things can be divided into two. Do you know what they are?To answer this question, look at these two pictures. Left is a picture of a plant cell and right is of an animal cell.
Strong and rigidTo trap light energy, to make food the green pigment
enclosed by cell membranContains organelles and granules :e.g. chloroplaste.g. mitochondrionProvide a medium for chemical reactions to take place
Glycogen granules as food storeNucleus at the centreStarch granules as food storeNucleus near cell wall
Stores glycogen granules and oil droplets in the cytoplasm
