Biology Test

QuestionAnswer
Who was the first to describe cells by looking through a microscope at them. (name and discover) and in what year? Robert Hooke 1665
Robert Hooke wrote a book called what? What is that book about? Micrographia Accurate and detailed record of his observations
Who was the first person to see living cells, and when? Anton Van Leewenhoek mid 1600s
What is the average range in size of animal cells? 10-50 microns
What is the average range in size of plant cells? 30-150 larger than animal cells
What are the shapes of cells? Rectangular, round/flat, disc (RBCs), long extensions (nerves), some change shape (WBC)
how many kinds of cells are there, and how many are in the human body? 200 kinds, 17 billion in human body
In what year did who observe many plants had cells? 1830s Matthias Schleiden
Who discovered varieties of animals had cells? Theodore Schwann
What is the cell theory? 1. All organisms are composed of one or more cells 2. cell is the basic unit of life 3. all cells come from preexisting cells
How found out that all cells come from preexisting cells? Virchow
What are the two types of cells? Prokaryotes and Eukaryotes
What are the characteristics of Prokaryotes? No nucleus No membrane bound organelles (ex. Bacteria and algae)
What are the characteristics of Eukaryotes True nucleus Membrane Bound Organelles (ex: humans, and plants)
What are the organelles in plants? Chloroplast
What are the organelles in animals? Centrioles, pinocytic vesicle
What is the outer boundary of plants? Cell wall
What is the outer boundary of animals? Cell membrane
What is the shape of plant cells? Angular
What is the shape of animal cells? Round-ish
What are the size of plant cells? Larger
what are the size of animal cells? Smaller
What is the color of plant cells? Green
What is the color of animal cells? Colorless (mostly)
How many vacuoles are in plant cells? 1 Large
How many vacuoles are in animal cells? Several small
The outer boundary of cells, and in plant cells are next to the inner surface of cell wall. And they regulate what leaves/ comes in cell, protects DNA, shapes cell, and separate contents from environments. All Cells Plasma membrane/ Cell membrane
In the outer boundary of nucleus. And they regulate what leaves/ comes in cell, protects DNA, separates nuclear contents from rest of cell. Eukaryotic plant and animal cells Nuclear membrane/ Nuclear Envelope
Center of cytoplasm/ cell. Stores DNA, synthesis of RNA, direct cell activity, (brain of cel). Eukaryotic plant and animal cells Nucleus
Inside nucleus. Site of chemical reaction, surrounds and bathes chromosomes. Eukaryotic plant and animal cells Nuclear sap/ Nucleoplasm
Inside nucleus. assembly of ribosomes, did not see when first looked at cells. Eukaryotic plant and animal cells "little nucleus"/ nucleolus
In nucleus or center of cytoplasm of cell. Stores genetic info, genes. ALL CELLS Chromatin/ Chromosomes
Area between the cell membrane, and nuclear membrane. Contains organelles, and site of all metabolic reactions. ALL CELLS Cytoplasm
Throughout the cytoplasm. prepares proteins for export, transports substances, synthesis of proteins and lipids. Eukaryotic plant and animal cells Endoplasmic Reticulum
Cytoplasm and on endoplasmic reticulum. Provides surface area for protein synthesis, link amino acids together, take out water. Eukaryotic plant and animal cells some bacteria (prokaryotes ) Ribosome
Cytoplasm. Cellular respiration converted in energy (ATP) Eukaryotic plant and animal cells Mitochondria "powerhouse"
Cytoplasm near nuclear (one pair in each cell). Forms spindle fibers for chromosome's migration during cell division, form microtubules. Eukaryotic animal cells centriole
Cytoplasm. storage, maintains stiffness in plants. Eukaryotic plant and animal cells (few prokaryotic cells) vacuole
Cytoplasm near ER. Processing and packaging substances produced by cell export, contain enzyme that make additional changes to proteins Eukaryotic plant and animal cells Golgi body
Cytoplasm. Digestion within cell, breaks down old cells defends cells from invading bacteria and viruses. Eukaryotic plant and animal cells Lysosome
On cell membrane. Bring in large amounts of food and water. Eukaryotic plant and animal cells Pinocytic vesicle
In cytoplasm. Photosynthesis. Eukaryotic plant cells Chloroplasts
Outside and next to cell membrane. Support and protect plant cells. Gives support to entire plant. ALL CELLS and some bacteria Cell wall
Do both prokaryotes and eukaryotes have DNA? Yes
Plant and animal cells both are classified as eukaryotes because they both have a what nucleus
How does DNA of a prokaryote differ from a eukaryote DNA is free floating in prokaryotes
Which structure is responsible for making the proteins Ribosomes
Traveling through a tunnel endoplasmic reticulum
What is a centrosome A container for the centrioles
Do plants have small or big vacuoles? Big
On cell membrane. Propels unicellular organisms through environment, moves substances through body. Animal cells & protists Cillia
On cell membrane. Propels cell through environment ex. sperm or bacteria. Few P and E Flagella
In cytoplasm. Forms cytoskeleton, contributes to the support of the cytoplasmic network, aids the movement of chromosomes in cell division, movement of organelles. Eukaryotic plant and animal cells few P cells Microtubules
In cytoplasm. Forms cytoskeleton, contributes to the support of the cytoplasmic network, aids the movement of chromosomes in cell division, aid cell movement- mini muscles Eukaryotic plant and animal cells few P cells microfilaments
In cytoplasm. Forms cytoskeleton, contributes to the support of the cytoplasmic network, aids the movement of chromosomes in cell division, movement of organelles Eukaryotic plant and animal cells Cytoskeleton
What is the difference in description between Microtubules and microfilaments Microtubules are hollow and microfilaments are not hollow and have thin rotten fibers
