Prokaryotic
What is a prokaryotic cell?
A prokaryotic cell is a simple, single-celled organism that lacks a nucleus and other membrane-bound organelles
What is a eukaryotic cell?
A eukaryotic cell is a complex cell that has a nucleus and membrane-bound organelles.
What is a tissue?
A tissue is a group of similar cells that work together to perform a specific function.
What is an organ?
An organ is a structure made up of different types of tissues that work together to perform a specific function in the body.
What is an organ system?
An organ system is a group of organs that work together to perform complex functions for the body.
Give an example of a prokaryotic organism.
Bacteria are examples of prokaryotic organisms.
Give an example of a eukaryotic organism.
Plants, animals, fungi, and protists are examples of eukaryotic organisms.
Can you name four types of tissues in the human body?
The four main types of tissues are epithelial tissue, connective tissue, muscle tissue, and nervous tissue.
Can you give an example of an organ in the human body?
Examples of organs include the heart, lungs, brain, liver, and stomach.
How many organ systems are there in the human body?
There are 11 major organ systems in the human body.
What is the defining feature of prokaryotic cells?
Prokaryotic cells do not have a nucleus; their genetic material is not enclosed in a membrane.
What is a defining feature of eukaryotic cells?
Eukaryotic cells have a nucleus that contains their genetic material.
What is the function of epithelial tissue?
Epithelial tissue covers body surfaces, lines cavities and organs, and helps protect the body.
Name one organ that is part of the nervous system.
The brain is a key organ in the nervous system, along with the spinal cord and nerves.
What is the role of the digestive system?
The digestive system breaks down food into nutrients that the body can use for energy, growth, and repair.
What is the function of the cell membrane in both prokaryotic and eukaryotic cells?
The cell membrane controls what enters and leaves the cell and provides protection.
What is one similarity between prokaryotic and eukaryotic cells?
Both types of cells have DNA and ribosomes, which are essential for protein synthesis.
What type of tissue connects different parts of the body together?
Connective tissue connects different parts of the body and provides support and structure.
What is the largest organ in the human body?
The largest organ in the human body is the skin. It protects internal organs and helps regulate body temperature.
What organs are part of the respiratory system?
The main organs of the respiratory system include the nose, trachea, lungs, and diaphragm.
How can you tell if a cell is prokaryotic under a microscope?
If the cell lacks a distinct nucleus and is smaller in size, it is likely prokaryotic.
Do eukaryotic cells have a cytoplasm?
Yes, eukaryotic cells have cytoplasm where cellular processes occur.
What is the function of muscle tissue?
Muscle tissue enables movement in the body by contracting and relaxing.
Which organ is essential for breathing and gas exchange?
The lungs are essential for breathing and gas exchange; they allow oxygen to enter the blood and carbon dioxide to be expelled from the body.
What is the function of the circulatory system?
The circulatory system transports blood, nutrients, oxygen, carbon dioxide, and hormones throughout the body.
