The cell theory states that the cell is the mst basic unit of life, all organisms are made of cells and all cells come from cells. What makes the cell theory a scientific theory?
It is based on a scientific publication that is read by scientists worldwide.
It is based on the work of many scientists and leads to accurate predictions.
It is based on ideas that have been proven true and that are not subject to revision.
It is based on preliminary evidence but still needs to be confirmed with experiments.
Which of the following pairs incorrectly matches a cell structure with its function?
Cell Membrane : Protein Synthesis
Nucleus : Information (DNA) storage
vacuole : storage
chloroplast : energy conversion
Which of the following is a function on the Golgi Apparatus?
Storing genetic information.
Recycling waste products of the cell.
Providing a protective barrier.
Processing and storing proteins.
What are the folds in the Golgi Apparatus called?
The cell membrane maintains homeostasis and is made of a combination of phospolipids and proteins.
Why is the cell membrane made of phospolipds and proteins?
The phospholipids prevent the membrane from dissolving and the proteins aid in semi-permeability.
Phospholipids have little oxygen and proteins cause enzyme catalyzed reactions.
What is the function of the ribosome?
To make proteins.
To make RNA.
To adhere to the Rough Endoplasmic Reticulum and adhere itself to the nucleus.
What is the function of lyosomes?
To transport the proteins
To carry out the waste of a cell.
What are chromosomes?
Long, thread-like bodies clearly visible during mitosis. Composed of DNA. Linear genes.
The central focus of a cell.
What invention was an early step in the discovery of cells?
Which of the following is NOT a component of the cell theory?
All Living things are made of one or more cells
The cell is the smallest unit of life
All new cells come from preexisting cells
All cells contain cell walls
Which organism creates the energy required by cells?
What organelle creates proteins?
Which organelle processes and transports proteins?
Which organelle contains digestive enzymes to break down foreign invaders?
Which organelle is a network of fibers that criss‐cross to support a cell from the inside?
Which organelle performs photosynthesis to make sugar?
Which organelle is thought to help with cell division in animal cells?
Which cell part is the internal fluid found in all cells?
Which organelle holds DNA and chromosomes?
The Rough Endoplasmic Reticulum is studded with ribosomes and is often the site of protein synthesis.
How does form fit function apply to cytology?
Neurons are long and thin as they typically connect to one another to perform tasks.
Red blood cells are typically small and have large vacuoles and more proteins in the cell membrane so that they can hold and transport oxygen and nutrients.
Plant Cells have cell walls to protect them from nature as they are exposed.
