Mitosis Mitosis is a division of the nucleus to produce two new daughter cells containing chromosomes identical to the parent cell. Significance of mitosis Growth- allows a zygote to produce more cell in order to grow Repair and replacement- allow the multicellular organism maintain its tissues‚ example skin cells and blood Asexual reproduction- clone The cell cycle divided into two major phases a. Interphase b. Mitosis Interphase is the period between division‚ divided into 3 sub phases (G1‚ S and

There are many ways in which substances can move across the cell membrane and in which then helps in the function of the body (cells‚ tissues and organs) overall. There are 3 processes that a substance can move across the membrane‚ theses are diffusion (simple and facilitated)‚ osmosis and active transport. Both diffusion and osmosis are passive processes‚ which mean they do not need energy to occur‚ whereas active transport does require energy. All three processes are involved in many functions

ANIMAL TISSUES 1. Classify the animal tissues. On the basis of the function they perform‚ animal tissues are classified into four different types. They are: i) Epithelial tissue ii) Connective tissue iii) Muscular tissue iv) Nervous tissue 2. What are epithelial tissues? What are the characteristic features of these tissues? The covering or protective tissues in the animal body are called epithelial tissues. They also perform the functions of secretion and absorption

A Cell Compared to a Hospital Cameron Browne The main organelle is the nucleus. I think the nucleus is like the hospital administration because the nucleus is the core of the cell that handles everything‚ and the hospital administration handles everything that goes on in the hospital. Without the “cores” for both the hospital and the cell‚ neither could properly functions. The nucleolus is the center of the nucleus‚ and it basically sends out all of the other organelles that work within the

September‚ 2013 Tissue Ownership “I think people are morally obligated to allow their bits and pieces to be used to advance knowledge to help others” (Korn). Different people have opposing opinions on the topic of whether or not patients or doctors own the body tissues after it’s been removed from the patient. Ownership is the act‚ state‚ or right of possessing something. Tissue ownership is different from ownership because once it leaves your body‚ you no longer own it. Contributing your tissues to the

There are four types of tissue found in animals: connective‚ muscle‚ nervous‚ and epithelial. We are going to go into muscle tissue. The cells of muscle tissues are called fibers. There are three types of muscle tissue and they are skeletal‚ cardiac‚ and smooth. All types can go though hypertrophy (enlargement or overgrowth of an organ or part of the body due to the increased size of the constituent cells). Muscle fibers contract due to the interaction of the contractile proteins‚ actin and myosin

Different type of tissues can be found in different organs. In humans‚ there re four basic types of tissue: epithelial tissue‚ connective tissue‚ muscular tissue‚ and nervous tissue. There may be various sub-tissues within each of the primary tissues. Epithelial tissue covers the body

Tissue Types Amy Chanda Morrison Colorado Christian University Our bodies have four different types of tissues. They are epithelial‚ connective‚ muscle and nervous. Each one has a specific job to do to keep the body in homeostasis. Patton stated “homeostasis is the relatively constant state maintained by the body” (pg.19). He also stated that “the precise and constant chemical composition of the internal environment must be maintained within very narrow limits‚ or sickness and death will result”
