1. You breathe the air which can contain bacerial cells.
2. The organism would die.
3. The nucleus holds DNA.
4. Robert Hooke and Anton van Leeuwenhooke.
5. Growth, reaction to stimuli, reproduction.
1. How are you exposed to cells everyday?
We’re exposed to cells when we eat, drink, smell, and touch because cells are around us and them maybe bacterial or viral, for example.
2. What would happen if cells did not regenerate?
We would disappear or die because our cells are always renewing with new cells as old cells die.
3. Why is the nucleus called the control center of the cell?
Because it contains the genetic information of the cell and it communicates with organelles in the cytoplasm and controls cell growth and reproduction.
4. Name the men who coined the cell theory.
The 3 men who coined the cell theory were Theodor Schwann, Matthias Jakob Schleiden, and Rudolf Virchow.
5. List the characteristics of life?
Cells- All living things except for viruses are made of one or more cells.
Organization- The cells of living things have different levels of organization. A group of cells forms tissue, a group of tissues form an organ, a group of organs form an organ system, and a group of organ systems make up the organism.
Energy Use- All organisms use energy for example, animals or heterotrophs eat food for energy and plants or autotrophs get food from the sun for energy through photosynthesis.
Homeostasis- Living things must maintain a stable functioning like the heart beating, having energy to fuel the body, maintaing temperature, and having enough water.
Growth- Organisms grow and change as cells divide.
Reproduction- So life doesn’t go extinct, all organisms reproduce through sexual or asexual reproduction.
1) I am exposed to cells every day by touching something living.
2) If cells did not reproduce then we would all be dead.
3) Because it is like the brain, it makes the different parts of the cell complete functions. The nucleus also has DNA that goes through different functions.
4) Hooke, Leeuwenhoek, Brown, and Scheilden.
5) Homeostasis, Reproduction, Growth, Respond to Stimulus, Uses Energy.
1. they are every where.
2. the world would end.
3.Matthias Schleiden and Theodor Schwann
1. You mean ‘exposed’ to cells ‘on’ a daily basis. I feel my body, I eat both plant and animals cells, and I ingest or inhale microbes.
2. Cells would grow old and die, leading to the death of the organism.
3. It contains the DNA/RNA connection and instructions to make the proteins that make up and run the cell.
4. Off the cuff, Virchow, Schleiden and Schwann (sp), but this is incomplete.
5. Hereditary material (like DNA), reproduction, metabolism, response to stimuli, both internal and external are 4 of them.
Hi, I was browsing the web looking for help to take my national boards this year, and ran into you on a google search with science in the phrase. Hope you make it; feel free to share, although your credentials put you way above my league. Tim Clifton, WV
1. How are you explosed to cells of the daily basis?
every time you get around a living organism you are around cells.
2. What would happen if cells did not reproduce?
you would walk around with a bunch of dead cells in your blood stream
3. Why is the nucleus called the controll center of the cell?
because it controls everything that goes on in the cell
4. Name the men who coined the cell theory.
Schwanne, Schlatten, and Luewenhooke
5. What are the characteristics of life?
Theme #1 – Cells-All living things are composed of one or more cells. Different types of cells have different “jobs” within the organism. Each life form begins from one cell, which then will split. These cells split, and so on. After this has happened several times, differentiation is undergone, when the cells change so that they are not the same thing anymore. Then they are used to begin to put together the final organism, some cells, for example, as the eyes, some as the heart, etc. The only arguable exception to this is viruses. They are not composed of cells, but are said to be “living.”
Theme#2 – Organization-Complex organization patterns are found in all living organisms. They arrange themselves on very small levels, grouping like things together. On larger levels, they become visible. This also has to do with differentiation, as the cells are organized in a manner that makes sense for the organism after they change to what they’ll be in the final organism.
Theme#3 – Energy Use-All organisms use energy. The sum of the chemical energy they use is called metabolism. This energy is used to carry out everything they do. Autotrophs (plants) use energy from the sun for photosynthesis, to make their own ‘food’ (glucose). Heterotrophs (animals and humans) must ingest food for this purpose.
Theme#4 – Homeostasis-All organisms have stable internal conditions which must be maintained in order to remain alive. These include temperature, water content, heartbeat, and other such things. In a way, this has to do with energy use, because a certain level of energy must be kept within the body at all times. For this, obviously, humans must then ingest food on a regular basis. Not all conditions are for the body to maintain itself; though most are.
Theme#5 – Growth-All organisms grow and change. Cells divide to form new, identical cells. Differentiation happens, as well, when cells mutate into other types of cells, making a more complex organism. Organisms growing, changing, and becoming more complex is called development. Single-celled organisms do grow as well, but they will only become slightly larger – this is nearly unmeasurable
Theme#6 – Reproduction-All organisms reproduce in order to continue the species’ life. This is combining genetic information (in sexual reproduction) or splitting into two organisms (in asexual reproduction) in order to create another of the same species. In sexual reproduction, the new organism will have some characteristics from the mother, and some from father. It may look like either of them, or it may not. In asexual reproduction, the new organism is an exact copy of the first. Sometimes, not every member of a species is able to reproduce. As long as others are (which we know they can, if they still exist today) then it does not threaten the species. (Except for mules, but don’t worry about them, they are a bizarre anomoly.)
4. Robert Hooke, Rudolph Virchow, Theodor Schwann, Mathais Jacob Schleiden, and Alexander Braun coined the cell theory, or had something to do with cells.

1. how are you exposed to cells of the daily basis? ( radioactivitity is the answer).
2.What would happen if cells did not rproduce? (tissue would die )

5. What are the characteristics of life? ( cells)
2) If cells did not reproduce then we would not be living right now, because cells have to reproduce to make us.
