Study Notes
Eukaryotic Cells and Tissues
- Eukaryotic cells develop into tissues and organisms. This is the introduction to the next unit of study.
Learning Outcomes
- Know the definition of a tissue.
- Understand the two different tissue types in plants.
- Give examples of different types of plant tissues and their functions.
- Understand the four different tissue types in animals.
- Give examples of different types of animal tissues and their functions.
- Describe the components of blood.
- Describe the individual blood components in relation to their biological function.
What is a Tissue?
- Tissue types vary in relation to the differences and diversity of living organisms and the activities/vital function of the tissues.
- A tissue is a group of similar cells working together, having an extracellular secretion specialized for performing one or more specific functions.
- Tissues may contain one or several different cell types.
Simple Plant Tissues
- Cells in simple tissues are symmetrical.
- Structure and shape are key identifiers of plant tissue types.
- In plants, parenchyma, collenchyma, and sclerenchyma are three tissue types.
Parenchyma Tissue
- Parenchyma cells are oval or round-shaped.
- Cell walls are loosely packed and soft.
- Parenchyma cells contain chlorophyll or contain areas for air.
- Parenchyma performs photosynthesis, stores nutrients (e.g., starch), and is responsible for aeration.
Collenchyma Tissue
- Collenchyma tissue is soft and living.
- It's composed of rectangular, elongated cells with fewer intercellular spaces.
- Cell walls are irregularly thickened with lignin.
- This tissue provides elasticity in plants.
Sclerenchyma Tissue
- Sclerenchyma is solid non-living tissue.
- These tissues have long, narrow, tough, thick-walled cells.
- They're thickened with lignin in addition to cellulose.
- Sclerenchyma gives plants elasticity and hardness, commonly found in fruit and nut shells.
Complex Tissues in Plants
- Two types of vascular conductive tissues: xylem and phloem.
- Xylem and phloem transport substances.
Xylem
- Made up of vessels, tracheids, and parenchyma cells.
- Xylem vessels are vertical rows of cells with dissolved lignin.
- Tracheids are composed of a single cell with no end walls.
- Xylem transports water and salts.
Phloem
- Consists of sieve tubes, companion cells, phloem parenchyma, and phloem fibers.
- Sieve tubes have no nuclei and perforated dividing walls.
- Companion cells support sieve tubes' energy needs.
- Phloem transports food (sugars).
Animal Tissues
- There are four main tissue types in animals that correspond to their functions.
- Epithelial, connective, muscle, and nerve tissue.
Epithelial Tissue
- This covers and lines internal and external surfaces.
- Four main subtypes: membranous, glandular, stratified, and simple.
- Simple epithelial tissues have one layer of cells and stratified epithelial tissues have multiple.
Connective Tissue
- Connects and surrounds other tissues.
- Includes many types: loose, dense, skeletal (cartilage and bone), and vascular (blood).
- Specialized cells in an extracellular matrix.
Muscle Tissue
- Contractile tissues
- Three types include skeletal, smooth, and cardiac.
- Skeletal muscle is voluntary, smooth is involuntary, and cardiac is involuntary with rhythmic contraction.
Nerve Tissue
- Contains neurons; transmit electrical impulses.
- Controls and coordinates body functions using sensory neurons, relay neurons, and motor neurons
Blood Components
- Blood consists of erythrocytes, a buffy coat, and plasma.
- Erythrocytes (red blood cells) comprise 45% of blood volume.
- Buffy coat contains platelets and leukocytes (<1%).
- Plasma makes up 55% of blood volume.
Blood Component Functions
- Erythrocytes are responsible for carrying oxygen and carbon dioxide.
- Plasma maintains osmotic pressure and acts as a carrier protein.
- Plasma also contains various proteins, electrolytes, and dissolved gases involved in various functions.
Immune System
- Innate and adaptive immune systems.
- Innate system is non-cellular and extremely fast.
- Physical barriers, inflammation, and complement cascade.
- Adaptive system is highly specific and takes weeks to develop.
- Clonal expansion and deletion are key parts of the adaptive response.
- Different immune cells (e.g., phagocytes, granulocytes, B cells, T cells) are categorized.
