A cell is the fundamental, structural, and functional unit of all living things. Plant cells do not have lysosomes or centrosomes, whereas animal cells do (or a pair of centrioles).
What is Plant cells?A plant cell is a eukaryotic cell with a true nucleus and organelles that perform specific functions. However, some organelles found in plant cells differ from those found in other eukaryotic cells. Organelles, cytoplasmic structures, cytosol, cell membrane (also known as plasma membrane), and cell wall are all components of a typical plant cell structure.Plastids, nucleus, mitochondria, endoplasmic reticulum, and Golgi apparatus are plant cell organelles. The plant cell is the fundamental unit of all plants. Plant and animal cells are both eukaryotic, which means they have a membrane-bound nucleus and organelles. The following is a summary of some of the most important characteristics of plant cells. See cell for a more in-depth explanation.To learn more about Plant cell refer to:

-They increase the rate of reaction by decreasing the activation energy of the reaction.
-As they are not used up in the reaction they are required in a small quantity.
-In biological system, enzymes are referred to as biological catalyst or biocatalyst. They are generally protein in nature and are very specific for their substrate. They also increases the rate of biological reaction by forming enzyme-substrate complex.
-Few examples of catalyst are: potassium permagnet, platinum, enzyme (like hexokinase, hydrolase etc) etc.

Write a brochure to third graders explaining the three different types of muscles? Give an example of each type and include a description of each in your article.

an example of a cardiac muscle muscles that contract the heart to pump blood. this heart muscle is a striped muscle in the walls of the heart. it is involuntary meaning a person cannot control it consciously.
an example of a smooth muscle is muscle tissue which is used by various systems to apply pressure to vessels and organs. this muscle is also involuntary and are usually in sheets or layers. your brain and body tell these muscles what to do without you even thinking about it.
an example of skeletal muscle are your biceps, deltoids, or even pectoralis. this muscle is called striated, meaning long or streak like, because the light and dark parts of the muscle fibers make them look striped(striated). these muscles are voluntary, which means they can control what you do.
