Cell Types
which of the following is the smallest?
ribosome
atom
tissue
bacteria cell
Atom
What are the four chromosomal mutations?
Deletion
Duplication
Inversion
Translocation
How many stages are there in mitosis?
Four
What is ecological succession?
The gradual replacement of one plant community with another through natural changes over time.
Plant Cell
are eukaryotic and have a rigid outer cell wall, chloroplasts, and large vacuoles. The do not have lysosomes.
Deletions
removes a base from the DNA sequence
What is the longest stage of the cell cycle called?
(S phase)interphase
Primary succession is about ________________.
Soil building
Nucleus
This is the control center of the cell and contains the DNA. Only eukaryotic cells have them.
Point Mutations - involve changes in one or a few nucleotides/bases.
involve changes in one or a few nucleotides/bases.
During what stage does the G1, S,and G2 phases happen?
Interphase
What grows after the early soil forms?
Simple plants like mosses and ferns grow in the new soil
Cell Wall
Plant cells have these. Some prokaryotes also them. They are on the outside of the cell and provide structure and protection for the cell.
Frameshift Mutation
caused by insertions and deletions that changes the reading sequence.
Usually causes a change in the amino acid sequence.
Put the stages of mitosis in order!
Prophase, metaphase, anaphase, telophase
What are lichens?
A mutualistic relationship between fungi and algae or fungi and cyanobacteria
Mitochondrion
This is where the cell creates energy. It's the powerhouse of the cell. The energy is made in the form of molecules called "ATP".
Chromosomal mutation
change in the number or structure of a chromosome.
Change the location of genes on a chromosome
Change the number of copies of genes.
Put the following actions in order: DNA replication, cell grows, cell division, cell prepares for mitosis
The cell grows and then there is a DNA replication. The cell then prepares for mitosis after the cell division happens
What happens TO THE SOIL when the simple plants die?
It thickens, and grasses, wildflowers, and other plants begin to take over and replace the lichens and mosses.
