Mitosis
Cell cycle
pattern of growth, DNA replication, and cell Division that occurs in a eukaryotic cell
Cell cycle
Mitosi
Cell cycle
Growth and normal metabolic processes take place
G2
Mitosis
G1
Synthesis
This is the correct order of mitosis Prophase,
Metaphase ,Anaphase ,Telophase
True
Fals
What limits the maximum amount of size of a cell?
G2
Synthesis
The ratio of cell surface area to volume
long continuous thread of DNA that consists of numerous genes along with regulatory information
Chromatin
Chromatid
Chromosomes
protein that organizes chromosomes and around which DNA wraps
Chromatid
Histone
Chromosomes
1st phase of mitosis when chromatin condenses, the nuclear envelope breaks down, the nucleolus disappears, and the centrosomes and centrioles migrate to opposite sides of the cell
Prophase
Telomere
Metaphase
What is Growth factor?
programmed cell death
broad group of proteins that stimulate cell division.
having no dangerous effect on health, especially
referring to an abnormal growth of cells that are not
cancerous.
Apoptosis are programmed cell death?
True
False
Asexual reproduction is creation of offspring from a single parent, does not involve the joining of gamets
True
False
Binary fission is Joining of gametes
True
False
group of cells that work together to perform a similar function
Tissue
Organ
Stem cell
What is Stem cells?
2 or more organs that work in a coordinated way to carry out similar functions.
cell that can divide for long periods of time while remaining undifferentiated
group of cells that work together to perform a similar function.
Organ is a group of different types of tissues that work together to perform a specific function or related functions.
False
True
Cell differentiation is a process by which unspecialized cells develop into their mature form and functions.
False
True
Differences between prokaryotic and eukaryotic
They have less DNA
Forms a separate new individual
What is Vegetative reproduction
Modification of a stem or underground structures of the parent
organism ex. Strawberries and potatoes
Parent organism splits into pieces, each can grow a new individual
Small projection grows on the surface of the parent organism
What is a benign tumor?
spreds out
You can remove it or you can stay with it
How are cancerous cells formed?
Normal cells that have damaged genes that make proteins for cell
growth regulation
Nucleus breaks apart, cell reorganized by cells of the immune system
What is Carcinogen?
cancerous tumor in which cells break away and
spread to other parts of the body, causing harm to the
organism’s health.
having no dangerous effect on health, especially
referring to an abnormal growth
substance that produces or promotes the
development of cancer.
Cancer is a common name of a class of diseases characterized
by uncontrolled cell division.
True
False
Growth factor are programmed cell death
True
False
What is Cytokinesis?
Chromosomes uncoil
Divides the cytoplasm into
two cells
Spindle fibers begin to
shortens
Metaphase is Sister chromatids separate
from each other
True
False
