Well I guess I should start with some weird and unusual facts about plants. Plants live in just about every place in the world. A plants called lichens can grow in extremely cold regions of the Arctic and Antarctica, and cacti grow in extremely hot, tropical deserts. Mushrooms can grow in dark caves, while algae can grow in the waters of seas, lakes, and ponds. The cells are the tiny units of life in a plant.
Tissues are the groups of cells that are very much alike in size and shape.
Each of the cells in a tissue does similar work. The organs of several different tissues. Tissues work together to do the job of an organ. The systems are groups of organs working together to perform one big job, such as getting food for an organism. The organisms are whole living things.
