Components of a Cell
This organelle is mostly filled with water. In plants this water serves to make the plant ridged.
What is a vacuole?
Robert Hooke coined the word "cell" after this.
What is a monastery chamber?
Molecules that travel from high concentration to low concentration.
Passive transport?
Composed of Phospholipid molecules lined up side by side in a double layer.
What is the nuclear membrane and the cell membrane?
This organelle has numerous ribosomes embedded within its membrane.
What is the rough endoplasmic reticulum.
The function of Lysosomes in animal cells.
What is to break apart food particles to serve the needs of the cell or in white blood cells they digest invading bacteria or viruses.
Antoine van Leuwenhoek discovered a powerful microscope with a single spherical lens to look at ...
Antoine van Leuwenhoek discovered this microscope to examine the quality of cloth
Simple Diffusion
What is it when small, nonpolar molecules travel directly through the plasma membrane.
Ribosomes, the protein-building factories of the cell are located in the?
What is the nucleolus?
Does not have a nucleus. DNA is loosely contained as a single chromosome.
What is a prokaryotic Cell?
Almost all the cellular DNA is located here.
What is the nucleus?
Modern times added additional tenets to cell theory.
4. Energy flow occurs within cells. 5.Hereditary information is passed on from cell to cell. 6. All cells have the same basic chemical composition.
Osmosis
What is the movement of water from a higher concentration of molecules to a lower concentration through a cell's semi-permeable membrane.
Three parts of a chloroplast.
What is Thylakoid, stroma, 2 membranes (inner and outer) grana (10-100 stacks)
DNA is contained as a single chromosome.
What is a Prokaryotic cell?
The interconnected network of membranes next to the nucleus.
What is the endoplasmic reticulum?
Early scientist established 3 tenets of cell theory still used today
1. All living things are made of cells. 2. Cells are the fundamental structure for living things. 3. Cells arise from pre-existing cells.
Key factor that requires certain substances to use active transport to cross the cell membrane
To move against a concentration gradient
Carries out ATP generating chemical reactions.
What is a mitochondria?
Harnesses energy from sunlight, converting it into potential energy stored in sugar molecules in plants.
What are Chloroplasts?
All cells share 4 features.
What 1. Contains DNA2. Enclosed by plasma membrane 3. Contains a fluid called cytosol 4.Includes protein factories call ribosomes?
The first to describe the cell as the fundamental unit of science.
Who is Henri Dutrochet.
Requires ATP energy to transport molecules against the concentration gradient.
What is active transport?
Cytoskeleton is composed of these.
What are the microtubules and filaments .
Considered the most important class of biomolecules for a cell.
Nucleic acids are considered the most important class of biomolecules for a cell, as they carry the genetic information (DNA and RNA) needed for cell function and reproduction. Other biomolecules like proteins, carbohydrates, and lipids are also vital for cell function, they rely on the information encoded in nucleic acids to perform their specific roles.
