Organs are groups of tissues working for a common purpose, which is photosynthesis in the case of a leaf. In plants, as in animals, similar cells performing similar functions are organised into tissues. The simple tissues (tissues with uniform cells) are composed of the same type of cells; complex tissues (tissues with more than one type of cells) are composed of more than one type of cell, these are unique to plants.

A leaf is an organ which is made out of tissues which are made out cells A leaf is comprized of epidermal tissue. acaulescent Mesophyl tissue, conductive tissue (Phloem and Xylem). Your nervous system is connected to your brain and your brain tells your muscle system what to do. Can be seen: Tissues need a microscope to be seen. In this section, we will discuss how a plant leaf is an example of an organ. The reason xylem is a complex tissue is because different cells make it up, whereas in a simple tissue is made up of the same cells. It helps the plants. Organ, tissue, or organism? organ , tissue , or organism? 25. These three motifs are continuous throughout an entire plant, but their properties vary significantly based upon the organ type in which they are located. In a like fashion, it can't be the organ because the branches of … Meristems produce cells that quickly differentiate, or specialize, and become permanent tissue. Please see section 1.3 for more information. An organ is a group of tissues with similar functions. An organ is a collection of tissues joined together as a structural unit in order to perform a common function. thanks goldenmonkey1997 goldenmonkey1997 It would be classified as an organ because leaves are primary organs of plants. We've mentioned the specialised cells found in a leaf in Unit 1, but here's the same diagram labelled with the tissues instead. This tissue enables the monocot leaf blade to increase in length from the leaf base; for example, it allows lawn grass leaves to elongate even after repeated mowing. Plants have cells, tissues and organs also. We will present its structure with respect to its functions in photosynthesis, gaseous exchange and transport. The below shows the Juxtaglomercular apparatus (JGA). Hope this helped! One example of a plant organ which is a leaf. Suppose a baseball pitcher throws the ball to his catcher.

The one in my opinion that best describes a leaf is tissue. An organ is composed of a similar type of tissues which perform the same function. Such cells take on specific roles and lose their ability to divide further. For this purpose, a leaf is typically flat (laminar) and thin, to expose the cells containing chloroplast (chlorenchyma tissue) to light over a broad area, and to allow light to penetrate fully into the tissues. Such cells take on specific roles and lose their ability to divide further. Anonymous. Plant life and animal life rely on many organs that coexist in organ systems.. A given organ's tissues can be broadly categorized as parenchyma, the tissue peculiar to (or at least archetypal of) the organ and that does the organ's specialized job, and stroma, the tissues with supportive, structural, connective, or ancillary functions.
