Study Notes
- Cells and their organelles are the building blocks of life
- A cell's organelles maintain life processes, requiring the input of materials and removal of wastes for efficient cellular function
- Cells, tissues, and organ systems are represented through diagrams which are used to communicate understanding, solve problems, and make predictions
- Organisms, including humans, consist of individual repeating units called cells
- A tissue is the name given when many cells of the same type work together
- An organ is the name given when different tissue types work together
- A body system is the name given when different organs work together
- Within cells are specialised components called organelles which can be thought of as "organs" of the cell
Nucleus
- It contains the cellular DNA
- Responsible for control of cellular functions
- The nucleus is surrounded by a nuclear envelope, which regulates the passage of substances through nuclear pores
Nucleolus
- A dense region within the nucleus containing cellular RNA
- RNA enables the process of transcription, that is protein synthesis (step 1)
Ribosome
- The site for translation, that is protein synthesis (step 2)
- Ribosomes can be found on the rough endoplasmic reticulum or freely in the cytoplasm
Rough Endoplasmic Reticulum
- Location for protein synthesis and then transport
- Chemical reactions can occur on its membranes
- Consists of ribosomes connected to flattened sacks
- It is connected to the nuclear membrane
Smooth Endoplasmic Reticulum
- A transport system for the cell and a site of chemical reactions
- Can synthesize lipids and detoxify drugs and alcohol
- Consists of flattened sacks without ribosomes
Mitochondria
- Produces energy, or ATP, through aerobic cellular respiration
- Glucose plus oxygen produces carbon dioxide, water, heat, and ATP
Golgi Body
- Packages molecules into vesicles for transport around the cell or body
- Packages unnecessary or hazardous molecules into lysosomes
Lysosome
- A double-membraned organelle that digests worn-out organelles and hazardous chemicals using the enzyme lysozyme
- Produced by golgi bodies
Centriole
- Creates a spindle for chromosome attachment during cellular reproduction, that is mitosis and meiosis
Cell Membrane
- A selectively permeable biphospholipid membrane
- Controls the movement of substances into and out of the cell
- Allows for intercellular communication
- Provides receptor sites for cell-specific chemicals such as hormones
Cytoplasm
- A jelly-like substance that occupies the remaining space in cells
- Location for chemical reactions including anaerobic cellular respiration
- Contains proteins, salts, ribosomes, and organelles
