A Virus is a nonliving structure that attacks cells and multiplies by injecting RNA or DNA telling the cell to make multiple copies of the virus.

This virus is attacking a small microorganism.


Bacteria are small single celled organisms that have a cell wall and do not have a well defined nucleus.

These are many bacteria together in one location


Archea are small single-celled organisms that have a cell wall and do not have a well, defined nucleus. Archea is very similar to bacteria but have a different rhibosome structure and tend to be extremophiles. Extremophiles can live in extreme conditions such as extremely high and low temperatures.

One of the small bodies in a cell's cytoplasm that are specialized to perform a specific function.

In eukaryotic cells, a process of cell division that forms two nuclei, each of which has the same number of chromosomes. The process of mitosis ensures that each new cell must get a copy of each of the chromosomes. Mitosis is divided into 5 phases, Interphase, Prophase, Metaphase, Anaphase, Telophase and Cytokinesis. First in Interphase mitosis has not begun yet, so the chromosomes will be copied, the chromosome then becomes two chromatids. In Prophase the the nuclear membrane will disolve and the chromosomes condense into rodlike structures. During metaphase the chromosomes will line up on the equator of the cell, then the homologous chromosomes will pair up. In the process of anaphase the chromatids must seperate then move to exact opposite sides of the cell. While telophase is going on something forms around each set of chromosomes called a nuclear membrane, then the chromosomes will unwind and mitosis is complete.



Is a process in cell division during which the number of chromosomes decreases to half the original number by two divisions of the nucleus which results in the production of sex cells. Before meiosis can begin the chromosomes are in threadlike form, each chromosome will make an exact copy of itself. Which forms two halves called chromatids.


This is a diagram of a leaf


Leaf structure:
Photosynthesis-the main function of a leaf is related to the structure of the leaf. On the outer-surface of a leaf there is something that prevents water loss from the leaf, which is called a cuticle. What lies beneath the cuticle is the upper epidermis. The upper epidermis is a single layer of cells. Stomata-which are tiny openings in the epidermis, allow carbon dioxide to enter the leaf. The center of a leaf is where most of photosynthesis takes place. That particular part of a leaf often had two-layers. Inside the palisade layer (the upper layer) hold several chloroplasts. Inside the chloroplasts is where photosynthesis takes place. Xylem and phloem are found in the spongy layer. The spongy layer is the space between the cells on the second layer. Also carbon dioxide moves freely in the spongy layer.

panda034_t.jpg I like panda's because they are cute, fat and fluffy. Also this is a funny video from youtube on a sneezing Panda.

Panda Facts:

  • They love eating bamboo
  • They are almost extinct
