Question Seven: Continuing to probe further, what came before multicellular organisms was unicellular organisms. What preceded unicellular organisms?You can further explore the endosymbiotic theory regarding mitochondria and unicellular organisms. Through such questioning, do you not feel that the plant world...
Cells are tiny units of life that make up all living organisms on Earth. Large organisms are often made of many cells and are known as multicellular organisms. Smaller organisms that are microscopic tend to be made of one cell and are known as s unicellular organism. ...
All organisms irrespective of unicellular or multicellular are made of cells. Hence, cells are the building blocks of life. They have the ability to carry all essential functions on their own. The structure of a cell includes various organelles that perform all crucial functions such as the produ...
Transformation can be done in unicellular or multicellular organisms. Transformation is the primary method for large scale production on medically important compounds, such as insulin. To produce insulin for diabetics, the insulin gene from humans is inserted into a plasmid (a genetic structure in a...
Plant, any multicellular, eukaryotic, usually photosynthetic life-form in the kingdom Plantae. There are an estimated 390,900 different species of plants known to science. Learn more about the plant kingdom, including the life and evolutionary histories
By definition, tissues are absent from unicellular organisms. Even among the simplest multicellular species, such as sponges, tissues are lacking or are poorlydifferentiated. But multicellular animals and plants that are more advanced have specialized tissues that can organize and regulate an organism’...
Quiz Course 18Kviews When did Plant Life First Appear on Earth? The earliest aquatic plants on Earth arose around 700 million years ago asalgae. Algae can be multicellular or unicellular and have pigments that help catch the light for photosynthesis. Water offers support to the pieces of algae...
Algae are photosynthetic aquatic organisms that are more commonly known as pond scum, seaweed or algal blooms. Many are unicellular organisms and they lack the root, stem, leaves and vasculature of higher plants. Others are multicellular and live in colonies. Blue-green algae are also called cyan...

They can be classified as either simple trichomes or glandular secreting trichomes. The simple trichomes on Arabidopsis leaves consist of a unicellular structure with a stalk and three to four branches. The glandular trichomes on tobacco leaves have a multicellular structure with a stalk terminating ...
