Study Notes
- Chapter 3 focuses on the organization of multicellular organisms and cells
Cells
- Cells are in both unicellular and multicellular organisms
- Multicellular organisms organize from cell to tissue to organ to organ system to organism
Definition of Terminology
- A cell is the basic unit of a living organism
- A tissue is a group of cells with similar structures performing a specific function
- An organ is a structure made of different tissues working together for a specific function
- An organ system is a group of organs working together for a common purpose
- An organism consists of various organ systems working together to perform life processes
Specialized Cells
- Specialised cells have developed certain characteristics/ structures to perform particular functions
- Examples: Neuron, Xylem cells, blood cells
Animal Specialized Cells
Adipose Cell
- These store energy in the form of fat, cushions, and provides insulation for body
- Has a location under the skin, between muscles, among intestines, and between various organs
- Adipose cells have large fat reservoir, pool
Neuron/ Nerve Cell
- There are found throughout the whole body
- A Dendrite are the end branches of a short projection of the cell body/soma and receive impulses.
- An Axon is the long projection of the cell body/soma
- It transmits/ sends away impulses from the soma
- The cells receive, process and send impulses/information.
Red Blood Cell
- Red blood cells are located in the blood vessels and the heart (cardiac)
- Haemoglobin (a red pigment) binds to oxygen.
- The shape is circular & biconcave to increase the surface area to volume ratio, therefore it can take in and release oxygen at a faster rate
- Lacks a nucleus to store more haemoglobin
- The cells function to transport oxygen to the whole body
Epithelial Cell
- These line the mouth, oesophagus, and blood vessels
- Simple squamous epithelial cells have a flat and thin shape
- Act as a protection, producing sweat, absorbing nutrients, and secreting enzymes.
Muscle Cells
- Voluntary actions can be controlled
- Involuntary actions are automatic and cannot controlled
Plant Specialized Cells
Root Hair Cell
- Located between the epidermis cells of the plant's root
- It includes a long and narrow cell membrane and cell wall extension to increase the surface area to volume ratio
- Absorbs water and mineral salts
Xylem cell
- Located in the root, stem, and leaves of the plant
- Xylem cells (vessels) are no longer alive
- They lose their end wall when mature, forming a continuous, hollow tube
- Has lignin to strengthen
- Transports minerals and water from the root up to the stem and into the leaves
Palisade Cell
- These cells are in leaves, under the epidermis cell
- Has many chloroplasts which contain large amounts of green pigment, the chlorophyll
- Performs Photosynthesis, converting solar (sun) light energy into chemical energy (glucose)
Identification
- A = Nerve Cell
- 1 = Nerve Tissue
- B = Red Blood Cell
- 3 = Connective tissue
- C = Adipose Cell
- 2 = Adipose Tissue
- D = Epithelial Cell
- 4 = Epithelial tissue
- A = Skeletal Muscle Cell
- B = Smooth Muscle Cell
- C = Cardiac Muscle Cell
- 1 = Cardiac Muscle Tissue
- 2 = Skeletal Muscle Tissue
- 3 = Smooth Muscle Tissue
- A = Xylem Cell
- 1 = Epidermis Tissue
- B = Root Hair Cell
- 2 = Xylem Tissue
- C = Palisade Cell
- 3 = Palisade Tissue
Epidermis Tissue
- This is epidermis tissue;
- Consists of lots of epidermis cells (root hair cells) that work together
- The function of epidermal tissue is for protection of the internal plant's parts and to absorb water and nutrient (on the root), and for exchange of gasses
Human Body systems
- Nervous system controls body movement and senses
- Monitors and maintains other body systems
- The digestive system stores and digest food, absorbs nutrients, and eliminates waste
- The circulatory system flows blood, nutrients, hormones, and oxygen
- The plant transport system carries water and minerals from roots to the leaves and glucose (food) from leaves to other organs
