What is the main function of the cell membrane?
Maintain cell shape
Produce energy
Store genetic information
Regulate passage of substances
Name three organelles found in a typical animal cell and their functions.
Nucleus, Mitochondria, Golgi apparatus
Lysosome - stores waste material, Endoplasmic reticulum - produces lipids, Peroxisome - breaks down fatty acids
Define the term 'tissue' in the context of biology.
A group of similar cells which come together to perform a specific function.
A type of molecule found in cells.
A group of organs working together.
A single cell that performs a specific function.
Explain the difference between a tissue and an organ.
A tissue is a type of fabric, while an organ is a part of the body
A tissue is a type of paper product, while an organ is a musical instrument
The main difference between a tissue and an organ is that a tissue is made up of a group of cells that work together to perform a specific function, whereas an organ is made up of a group of tissues that work together to perform a specific function.
A tissue is a type of food, while an organ is a type of plant
How are organ systems different from individual organs?
Organ systems are smaller in size compared to individual organs.
Organ systems perform only one function, unlike individual organs.
Individual organs are always found in pairs, while organ systems are not.
Organ systems involve multiple organs working together, whereas individual organs are single structures with specific functions.
What is the role of the phospholipid bilayer in the cell membrane?
Semi-permeable barrier and structural support
Energy production
Cell division
Waste removal
Describe the function of the mitochondria in a cell.
The mitochondria function to regulate and regulate cellular processes
The mitochondria function to generate ATP through cellular respiration.
The mitochondria function to store genetic material
The mitochondria function to synthesize proteins
What is the function of the Golgi apparatus?
Stores genetic information
Produces energy for the cell
Processes, sorts, and packages proteins and lipids
Regulates cell division
What are the four main types of tissues found in the human body?
skin tissue, ligament tissue, cardiac tissue, and brain tissue
bone tissue, cartilage tissue, blood tissue, and fat tissue
smooth tissue, rough tissue, striated tissue, and cardiac tissue
epithelial tissue, connective tissue, muscle tissue, and nervous tissue
Give an example of an organ and explain its function.
Brain
Lungs
Stomach
Heart
How do organs work together within an organ system?
By working independently without any coordination
By communicating through telepathy
By performing specialized functions and coordinating activities through various mechanisms such as chemical signals, nerve impulses, and physical connections.
By randomly selecting tasks to perform
What is the function of the endoplasmic reticulum in a cell?
Photosynthesis, respiration
Cell division, DNA replication
Protein and lipid synthesis, molecule transportation
Energy production, waste removal
Explain the concept of cell specialization.
Cell specialization is the process of cells losing their functions.
Cell specialization is the process of cells multiplying uncontrollably.
Cell specialization is the process by which cells develop specific structures and functions to perform particular tasks within an organism.
Cell specialization is the process of cells becoming identical to each other.
Describe the structure and function of the nucleus in a cell.
The nucleus is responsible for protein synthesis in the cell
The nucleus is a membrane-bound organelle that contains the cell's genetic material (DNA) and serves as the control center of the cell.
The nucleus contains the cell's cytoplasm
The nucleus is a non-membrane-bound organelle in the cell
How do cells communicate with each other in a multicellular organism?
Morse code
Chemical signals like hormones, neurotransmitters, and cytokines
Smoke signals
Cellular telepathy
