___________a molecule that is present in all living cells and that contains the information that determines the traits a living thing inherits and needs to live.
Cell
Stimulus
Homeostasis
DNA
Which statement was NOT included in cell theory?
All living things are composed of cells.
Living cells come only from other living cells.
Each cell contains a cell membrane, cytoplasm, nucleus, mitochondria, and endoplasmic reticulum.
Cells are the smallest structure of living things that can perform the functions necessary for life.
Who discovered and named cells while looking at cork?
Captain Hook
Robert Hooke
Matthais Schleiden
Rudolf Virchow
What was Schleiden convinced of?
All plants are made of cells
All animals are made of cells
All cells are prokaryotic
None of the above
Who noted that all animals are made of cells and helped write the first two parts of cell theory?
Rudolf Virchow
Anton van Leeuwenhoek
Theodor Schwann
Robert Hooke
Who discovered that all cells come from other living cells and had research that lead to the last major principle of cell theory?
Matthias Schleiden
Theodore Schwann
Robert Hooke
Rudolf Virchow
These three scientists together helped come up with the second part of the cell theory (all living things are made of one or more cells). CHOOSE 3 ANSWERS
Schleiden
Leeowenhoek
Hooke
Virchow
Schwann
The cell power house where nutrients are digested and energy is created for the cell. It is also responsible for cellular respiration.
lysosome
mitochondria
cytoplasm
ER
Storage where food nutrients and waste are kep
cytoplasm
mitochondria
vacuole
Golgi Body
These connect amino acids to build proteins in the cell. They are needed for cell function
cell membrane
ribosomes
vacuole
golgi Body
Made of cellulose. Unique to plant cells
cell wall
cytoplasm
chloroplast
mitochondria
Produce food by converting light energy into sugar that cells can use. (Plant cells )
cell wall
cytoplasm
chloroplast
mitochondria
If the cell is considered to be EUKARYOTIC, what does that mean about its DNA and nucleus?
It DOES have a NUCLEUS, and the DNA is INSIDE the NUCLEUS
It DOES NOT have a NUCLEUS, and the DNA is free floating in the cytoplasm.
This structure provides protection and structure to ALL plant cells & SOME prokaryotes. Animal cells DO NOT have this.
Plasma Membrane
Cell Wall
Golgi Apparatus
Ribosomes
This is what controls what goes into and out of the cell (helps maintain homeostasis). It is made of lipids and ALL CELLS have this.
Plasma Membrane
Cell Wall
Lysosomes
Vacuole
I am an organelle that helps clean up the cell, break down food, break down the cell when it is dead, and is also considered an enzyme.
Nucleolus
Nucleus
Lysosome
Ribososme
Both prokaryotic & eukaryotic cells have all 4 of these!
Cytoplasm, Ribosomes, Mitochondria, Vacuole
DNA, Cytoplasm, Chloroplasts, Plasma Membrane
Ribosomes, DNA, Nucleus, Cytoplasm
Plasma Membrane, Ribosomes, DNA, Cytoplasm
The theory of Endosymbiosis explains
The origin of eukaryotes
How bacteria live
How species develop
Why cells rely on one another
____________ & _________________ are organelles that definitely arose from endosymbiosis.
Nucleus and cell membrane
Chloroplast and mitochondria
Mitochondria and nucleus
Cell wall and chloroplast
Which of the following is evidence to support the endosymbiotic theory?
Mitochondria and chloroplasts have their own DNA, which is similar to prokaryotic DNA.
Fossil evidence shows that the first forms of life were prokaryotic cells.
All eukaryotic cells have a double-layered membrane composed of phosplipids and proteins.
Prokaryotes have the same number and types of enzymes as eukaryotes.
Mitochondria , chloroplast , and bacteria are similar in size.
true
false
Eukaryotes are thought to have evolved by a prokaryote engulfing one heterotrophic bacteria and one photosynthetic bacteria.
false
true
A few days after fertilization, cells in the embryo begin to turn on and off particular genes in order to become particular cell types. This process is called...
Differentiation / Specialization
Homeostasis
The cell cycle
Mitosis
Why are your muscle cells different from your nerve cells?
muscle and nerve cells have different DNA, different genes
muscle and nerve cells have the same DNA (same genes) but different genes are turned on
muscle and nerve cells began with the same DNA (same genes) but some different genes were destroyed by each cell type
muscle cells are not different from nerve cells, they are the same
