CELLS (1) by Mind Map: CELLS (1)

1. Structure and Functions

1.1. Eukaryotic Cells

1.1.1. Plant Cell Cell Wall Outer layer of the cell that provides support Chloroplast Contains the chlorophyll which is the site of photosynthesis. It is the site of photosynthesis Central Vacuole Storage compartment for water, sugar, ions, and pigments. Plasmodesmata Openings in the cell wall that functions during cell-to-cell communication

1.1.2. Common Organelles Plasma Membrane Lipid bilayer in which proteins are embedded Cytoplasm Semifluid matrix that contains the nucleus and other organelles Mitochondria Powerhouse of the cell Cytoskeleton Supports the organelles as well as the cell shape and it also plays a role in cell motion Nucleus It is the command center of the cell. It also contains the hereditary information of the cell Endoplasmic Reticulum Smooth ER Rough ER Golgi Apparatus Collects, packages, and distributes molecules manufactured in the cell Peroxisome Vesicle that contain enzymes that carry out particular reaction such as detoxifying potentially harmful molecules Lysosome Vesicle that breaks down macromolecules and digests worn out cell components

1.1.3. Animal Cell Centriole Complex assembly of microtubules that occurs in pairs

1.2. Prokaryotic Cells

1.2.1. Cell Wall Protects the cell and provides support and shape

1.2.2. Cytoplasm Gel like substance that contains enzymes, salts, cell components, and other organic molecules

1.2.3. Cell Membrane It surrounds the cell's cytoplasm and regulates the flow of substances

1.2.4. Pili Hair-like structures that allows the cell to attach to other cells and surfaces.

1.2.5. Flagella Long, whip-like protrutions that helps in cell locomotion

1.2.6. Ribosomes Cell structure that is responsible for protein production

1.2.7. Plasmids Circular DNA structures that carries the genes

1.2.8. Nucleoid Region Region that contains the single bacterial DNA molecule

1.2.9. Capsule Additional covering to the cell

2. Biomolecules

2.1. Biomolecules, aka macromolecules, are molecules produced by the cell

2.1.1. Carbohydrates Monomer: Monosaccharides It is the quickest energy source

2.1.2. Lipids Monomer: Fatty acids and glycerol Can be used as alternative source of energy and can provide insulation Non polar

2.1.3. Proteins Monomer: Amino acids Composed of chains of amino acids that is essential in muscle development

2.1.4. Nucleic Acids Monomer: Nucleotides Essential in directing the protein synthesis DNA RNA

3. Bioenergetics

3.1. The transformation of energy that occurs in living organisms

3.1.1. Endergonic Reaction Requires energy Photosynthesis

3.1.2. Exergonic Reaction Releases energy Cellular Respiration

4. Division and Reproduction

4.1. Eukaryotes

4.1.1. Mitosis A parent cell divides into two identical cells

4.1.2. Meiosis A process which occurs in gametes. A parent cell divides twice to produce 4 varying daughter cells

4.2. Prokaryotes

4.2.1. Binary Fission The cell's genetic material (DNA) is duplicated and then the cell elongates then the septum forms and the cell pinches into two

5. Transport Mechanism

5.1. Occurs in the plasma membrane, its function is to maintain homeostasis

5.1.1. Active Transport Uses energy (ATP) Endocytosis Exocytosis Sodium-Potassium Pump

5.1.2. Passive Transport Doesn't use energy Simple diffusion Facilitated diffusion Osmosis
