Parts of The Cell
Structures in the cytoplasm where proteins are made
Ribosomes
Phase of spindle fibers attach to each chromosome and then align the chromosomes along the cell equator.
Metaphase
What is cell reproduction?
the process by which cells divide to form new cells
Phase of cell growth
G1 phase
A basic principle of genetics and explains how characteristics are passed from one generation to the next.
genetic inheritance
Which organelle is animal cell doesn't have?
A. cell membrane
B. ribosome
C. chloroplast
C. chloroplast
What is mitosis?
a type of cell division that results in two daughter cells
How many chromosomes each human has?
46
the cytoplasm of the cell is split in two, making two new cells.
cytokinesis
Which definition is this?
Alleles that are masked or hidden by dominant alleles are known as recessive alleles. In some situations, both alleles are expressed equally. A genetic scenario where neither allele is dominant or recessive and both get expressed is known as it.
A. Co-dominance
B. Incomprecate Dominance
A. Co-dominance
Why cell membrane does need?
It maintains the integrity of a cell and controls passage of materials into and out of the cell.
begins with diploid cells and ends with haploid cells
The process of meiosis
A picture of the chromosomes in a dividing cell
karyotype
What is the longest phase of the cell cycle?
During cell division
If baby has two copies of the X chromosome, it would be...
A. Boy
B. Girl
B. Girl
Which cell has many lysosomes to help break down nutrients?
A. Animal cell
B. Plant cell
A. Animal cell
stages of mitosis is
prophase, metaphase, anaphase, telophase
If there are 16 chromosomes in the egg cells of an organism, how many chromosomes would be found in its muscle cells?
32
Why is the cell cycle important?
replication and reproduction of cells
(overall it allows biotic to survive)
What is the difference between Haploid cells and Diploid cells?
Diploid cells contain two complete sets (2n) of chromosomes. Haploid cells have half the number of chromosomes (n) as diploid.
Structure in plants made of cellulose that is outside of the cell membrane
Cell Wall
Which of the following is mitosis not used for?
A Repair (of a wound) in multicellular organisms
B Asexual reproduction in unicellular organisms
C Development (e.g., baby in mother's womb) D Production of gametes
E All of the above use mitosis
D Production of gametes
uncontrolled growth and division of cells
failure in the regulation of the cell cycle
They would cause...
cancer
During which stage is the cell actively doing its special job?
Interphase
The process where homologous chromosomes pair up with each other and exchange different segments of genetic material to form recombinant chromosomes.
Crossing over
