We did this project to learn more about macromolecules, cells, and types of diffusion. We did this project by making a poster and observing cells in a microscope. We took multiple pages of notes to better learn the topic.

The four macromolecules are :

• Lipids
  • Monomer : Fatty Acids
  • Function : Make up cell membrane, provides long-term energy
• Proteins
  • Monomer : Amino acids
  • Function : Build/repair muscle, enzymes that speed up chemical reactions
• Nucleic Acid
  • Monomer : Nucleotides
  • Polymer : DNA or RNA
  • Function : Carry genetic information
• Carbohydrates
  • Monomer : Simple sugars (Monosaccharides)
  • Polymer : Complex sugars (Polysaccharides)
  • Function : Provides short-term energy (simple), provides long-term energy (complex)

Diffusion : movement of anything from a region of higher concentration to a region of lower concentration

Facilitated diffusion : the passive movement of molecules along their concentration gradient

Passive transport : a movement across cell membranes without need of energy input

Exocytosis : a process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane

Endocytosis : substances are brought into the cell

Osmosis : movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides

Cytoplasm : the material or protoplasm within a living cell, excluding the nucleus

Mitochondria : powerhouse of the cell

Vacuole : extremely important in providing structural support, as well as serving functions such as storage, waste disposal, protection, and growth

Centriole : occurring in pairs and involved in the development of spindle fibers in cell division

Cell Membrane : the semipermeable membrane surrounding the cytoplasm of a cell

Cell wall : a rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants

Ribosomes : a minute particle consisting of RNA and associated proteins found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins.

Golgi body : involved in the transport of lipids around the cell, and the creation of lysosomes

Endoplasmic Reticulum : a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. Rough ER has ribosomes attached and is involved in protein and lipid synthesis.

Nucleus : contains most of the cell's DNA

Nucleolus : a small dense spherical structure in the nucleus of a cell during interphase

Chloroplast : a plastid that contains chlorophyll and in which photosynthesis takes place

Organelles -> Cell -> Tissue -> Organ -> Organ System -> Organism

We did this poster on the cells & their organelles. On the bottom right, you can see passive transport. On the top right, you can see a zoomed in picture of the cell membrane

Though this was a really short project, I felt we learned A LOT. We had success in time management. We finished all of our assignments efficiently. I felt that I had a lot of success being a conscientious learner. I was mostly always on task, and I used outside resources to find my answer.

We had trouble in being collaborative. We barely talked and we went our separate ways after we finished. I also felt I could have been a better collaborator. I talk a lot, but I just did not talk a lot when finishing this project.
