Study Notes
Motion Class 9th One Shot Series
- The series covers topics related to motion in class 9th.
- There are five topics in the series.
Topic Breakdown
- Topic 1: Equation of Motion
- Topic 2: Distance and Displacement, Motion, and Velocity
- Topic 3: Acceleration
- Topic 4: (Not specified)
- Topic 5: Circular Motion
Cell Structure and Functions
- Endoplasmic Reticulum (ER) functions as both an intercellular transport system and a manufacturing surface.
- ER provides a framework for the organelles.
Characteristics of Cells
- Cells are the basic units of life.
- All plants and animals are composed of cells.
- A cell is a building unit of an organism.
Organelles
- Lysosomes serve as an intracellular digestive system and are also known as digestive bags or suicide bags of the cell.
- Mitochondria are present in bacteria and the red blood cells of mammals, and synthesize energy-rich compounds (ATP), making them the powerhouses of the cell.
- Mitochondria are found in both bacteria and the red blood cells of mammals.
- Chromoplasts are present in flowers, fruits, or any other colored part of the plant (other than green part).
- Chloroplasts are present in leaves and stem of plant (green part).
- Leucoplasts are present anywhere in plant as they are colorless and store food.
Cell Transport
- Endocytosis is the ingestion or engulfment of food and other material by folding of the plasma membrane, as seen in Amoeba.
- Active transport is the process in which molecules are moved uphill against the concentration gradient, requiring energy.
- Passive transport involves movement of molecules along the concentration gradient, requiring no energy.
Cellular Components
- Chromosomes are made up of DNA and Protein.
- Cytosol is the semifluid part of the cell cytoplasm which is embedded in between cell organelles.
- Cytoskeleton is a network of protein fibers present in the cell, providing a supporting framework for the organelles.
Cell Division
- The phenomenon where cytoplasm shrinks in a hypertonic medium is called Plasmolysis.
History of Cell Discovery
- Robert Hooke coined the term "cell".
